Best MagSafe portable battery pack, magnetic wireless power bank and charger 2026: iPhone 12, 13, 14, 15, 16 and 17

• Capacity: 39.5Wh (10000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (25W Qi2.2) & USB-C (35W)
• Macworld Recharge Test Score: 177%
• Weight: 8.65oz (245g)
• Dimensions: 4.2 x 2.8 x 0.9 inches (107 x 71 x 22mm)
• Colors: Black

The Kuxiu S3 was the first semi-solid-state 25W magnetic wireless power bank to enter the Macworld Lab. A semi-solid state (SSS) power bank is more energy-dense than a traditional liquid electrolyte power bank because its semi-solid electrolyte is less prone to leakage and thermal runaway. SSS is therefore more durable, safer and offers more charge cycles so will last longer.

Indeed, not only does it tick those boxes but its also boasts three other top-end features: a built-in USB-C cable, integrated kickstand, and super-clear digital battery display.

Only the iPhones 16 and 17 support the very fastest wireless tech Qi2 25W, and only the iPhone 15 and later have a USB-C charging port. Older iPhones (from 12 on) can use a 25W charger such as the S3 but are pegged back at 15W—still faster than the 7.5W found on cheaper power banks.

Switch to wired charging via the integrated USB-C cable and you’ll achieve up to 35W so even faster.

The S3 has a 10000mAh (10K) battery capacity and managed to recharge that same iPhone to 177%—so up to 100% then another 77% when it came to a second recharging task. That’s not the top score we’ve had in our 10K power bank tests: the champ so far is the Ugreen MagFlow Air 10K, which scored an unmatched 208%, with the EcoFlow RAPID 10K and Anker MagGo Slim scoring 190% or close—both are reviewed here. But 177% is above average.

The same company offers two other 25W magnetic power banks: the similar S4 reviewed below, and the K1 Ultra (reviewed in our multi-device section below) that has a neat slide-out panel that can charge your Apple Watch or AirPods at the same time as the iPhone.

• Capacity: 39.2Wh (10000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (15W Qi2) & USB-C (30W)
• Macworld Recharge Test Score: 208%
• Weight: 7.55oz (214g)
• Dimensions: 4.1 x 2.7 x 0.53 inches (112 x 70 x 13.9mm)
• Colors: Gray, Blue, White

It might lack the very fastest 25W wireless tech but the 10K Ugreen MagFlow Air packs a built-in USB-C cable that can connect to an iPhone 15 or later and charge at 30W.

What really wowed us, though, was its performance in our recharging tests. It scored 208%, so two full charges and a trickle on the third round. The previous champ, the EcoFlow RAPID 10K, scored 190%. There are a bunch of environmental factors that come into play each time you charge but there’s no doubting that the MagFlow Air is an ace.

It’s also nearly as thin as the Kuxiu S4, the slimmest 10K battery pack reviewed above.

There’s a 5K MagFlow Air model, reviewed with the other small power banks further down, and that too won its class on battery capacity.

Somewhat confusingly, Ugreen also sells a non-Air 10K MagFlow Power Bank, shown above, that is faster at 25W wireless but scored a less impressive 144% in our recharging tests. The Kuxiu S3 is a better choice at that speed, or its S4 sibling, reviewed below, if you want something even slimmer than the MagFlow Air 10K.

• Capacity: 39.2Wh (10000mAh)
• Input charger: USB-C (45W)
• Output charger: Wireless (25W Qi2.2) & USB-C (45W)
• Macworld Recharge Test Score: 185%
• Weight: 6.9oz (196g)
• Dimensions: 4.1 x 2.8 x 0.53 inches (105 x 71 x 13.7mm)
• Colors: Space Gray, Silver, Metallic Mocha, Lilac, Orange, Navy

The Iniu SnapGo Air matches the Kuxiu S4, reviewed below, as the slimmest 10K magnetic portable charger we’ve had in for testing. It’s a little lighter but a tiny bit wider, and it scored with a similar result in our iPhone recharging tests.

It beats the S4 with 45W wired charging (but matched it on 25W wireless) and by including a detachable (but not built-in) USB-C cable. It’s also available in a wider range of colors. Unlike the S4 it’s not semi solid state, which may mean it can perform fewer recharge cycles although it will take you a long time to find out. There are two USB-C ports but total output is pegged back to 15W when more than one id used at the same time.

Its neat base-mounted digital display is helpful and better than most LED indicators but the S4’s display shows a bit more information if you need it. The S4 also features a kickstand, missing from the SnapGo Air.

• Capacity: 38.5Wh (10000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (25W Qi2.2) & USB-C (30W)
• Macworld Recharge Test Score: 182%
• Weight: 7.55oz (214g)
• Dimensions: 4.1 x 2.7 x 0.53 inches (104 x 69 x 13.7mm)
• Colors: Black, Cosmic Orange

Like its S3 sibling, the Kuxiu S4 is a semi-solid-state 25W magnetic wireless power bank with all the safety and durability benefits gained from that technology.

While it lacks the S3’s super-useful and powerful built-in 30W USB-C cable, it measures up in terms of slim profile. At just 13.7mm thin, it’s the slimmest 10K power bank we’ve tested (equakl with the Iniu SnapGo Air 10K, reviewed above). The S3 and most 10K power banks look chunky in comparison. If you want thinner, you need to switch down to a 5K capacity power bank.

Its integrated kickstand is not quite as robust as that found on the S3 but it does the job well enough, and its digital battery display carries even more charging information.

You’ll need to bring your own cable to switch to wired charging for 30W output. The S4 recharged our test iPhone to 182%, so a little higher than the S3 but close enough for the difference to be down to environmental factors such as temperature.

• Capacity: 38.7Wh (10000mAh)
• Input charger: USB-C (65W)
• Output charger: Wireless (15W Qi2) & USB-C (30W)
• Macworld Recharge Test Score: 190%
• Weight: 9.7oz (275g)
• Dimensions: 4.25-x-2.8-x-0.9 inches (108-x-70-x-23mm)
• Colors: Gray/silver

The EcoFlow RAPID 10K has a large capacity, refilling a iPhone 16 Pro twice over in our tests—close to the best we’d seen, with only the Ugreen MagFLow Air 10K beating it. What makes this power bank special—although not unique—is its short built-in USB-C cable that can be used for fast-charging an iPhone 15, 16 or 17 or refilling the power bank itself. The cable fits neatly away when not in use at the bottom of the power bank. It’s the highest rated we’ve tested with 65W input and output.

Wirelessly it will work with any MagSafe iPhone (12/13/14/15/16/17) at 15W. iPhone 15/16/17 users can connect via the integrated USB-C cable or a separate longer cable via the side USB-C port if required, for faster 30W charging. Owners of earlier iPhones can use a USB-C to Lightning cable instead for fast 20W wired charging from the power bank’s port. Note that the iPhone 16e does not work with magnetic wireless charging.

For faster wireless charging, consider the new generation of Qi2 25W power banks such as the Kuxiu S3, Baseus PicoGo and Iniu SnapGo Air reviewed here. That said, the 25W power banks we have tested didn’t match the EcoFlow or Ugreen MagFlow Air on battery capacity in our tests, although they are not too far behind.

No 10K magnetic wireless power bank can match the EcoFlow on input speed—that is the rate at which it is recharged itself. Its 65W is much faster than the average 30W input speed.

While winning on charging performance and capacity, the EcoFlow Rapid is reasonably chunky compared to the Ugreen MagFlow Air, Anker MagGo Slim and Benks ArmorGo, and notably bulkier than smaller-capacity 5K power banks. It’s still pocketable but the slightly larger size is the compromise for the other benefits. If you want a slimmer battery pack, look for a smaller 5000mAh option—we’ve tested the best slim power banks further on. It has a handy pull-out kickstand at the back.

• Capacity: 38.7Wh (10000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (15W Qi2), USB-C (30W)
• Macworld Recharge Test Score: 188%
• Weight: 7.05oz (200g)
• Dimensions: 4.1 x 2.8 x 0.58 inches (104 x 71 x 14.7mm)
• Colors: Black, White, Pink, Teal

At just 14.7mm thick, the 10000mAh Anker MagGo Slim power bank rivals even some of the 5000mAh battery packs in terms of slimness. Only the 13.7mm Kuxiu S4 is thinner. It’s also lighter than any other 10K magnetic wireless power bank that we have tested, and scores highly on recharging power. Built-in USB-C cables are nice but I admit that the svelte Anker Slim is the magnetic power bank in my backpack every day.

It uses fast Qi2 magnetic tech, so can wirelessly charge at an impressive 15W. If you have a spare cable with you, it can charge at twice that speed via its USB-C port. This makes it as fast a wireless charger as the EcoFlow RAPID reviewed above but slower than the bulkier Kuxiu S3 or S4. The EcoFlow charger is more convenient with its built-in USB-C cable, but owners of iPhones 12/13/14 might appreciate the ability to add a Lightning cable to the USB-C port and charge that way.

In our tests it performed among the best of the 10K magnetic power banks we have put through their paces: recharging an iPhone 15 Pro to 188% (over the course of two iPhone charges from one power bank charge).

It’s available in up to four colors depending on your country and where you buy it, including pink and teal versions.

There’s an even slimmer 5K Anker Nano model, reviewed below.

• Capacity: 36Wh (10000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (25W Qi2.2) & USB-C (45W)
• Macworld Recharge Test Score: 182%
• Weight: 7.45oz (196g)
• Dimensions: 4.1 x 2.6 x 0.63 inches (102 x 67 x 16mm)
• Colors: Black

This 25W wireless power bank lived up to its claims of wirelessly charging an iPhone 16 Pro from 0% to 50% in 36 minutes—12 to 15 minutes faster than a 15W power bank. That might not sound a lot but when you’re in a rush to charge your phone, every minute counts. 25W wireless charging is limited to the iPhone 16 and 17 families, running at least iOS 26; older iPhones will charge at 15W using this power bank.

Most 10K wireless power banks are around 22mm deep, so the 16mm-thin Baseus PicoGo Magnetic 10K Power Bank (AM52) is one of the slimmest we’ve tested. The Kuxiu S4 reviewed above is even slimmer at just under 14mm but the AM52 is certainly thinner than most.

The AM52 is an output blazer is more ways than one. It is certified Qi 2.2 so charges wirelessly at 25W, as fast as the Ugreen MagFlow reviewed below, and like the MagFlow also boasts an option with a built-in USB-C cable. And if you choose wired charging, you can access output at 45W—the fastest of any magnetic wireless power bank reviewed here, alongside the Iniu SnapGo Air reviewed above. If you use the wireless charging pad, the handy integrated USB-C cable and the spare USB-C port to simultaneously charge three devices—say your iPhone, Apple Watch and AirPods—total output is restricted to 15W.

When recharging an iPhone, it refilled our test 16 Pro more than one and a half times, scoring an impressive 182% in the Macworld Recharge Score. Other 10K power banks have performed a little better: we recorded scores of 208% with the 15W Ugreen MagFlow Air 10K and 190% with the 15W EcoFlow Rapid 10K and 7.5W Anker Zolo 10K, although both lag behind the Baseus in terms of charging speed.

The Baseus PicoGo AM52 costs $69.99 / £59.99 for the model with no integrated cable and $79.99 / £69.99 for the AM52 with cable built in. We think that extra ten bucks is worth it for the convenience of the built-in cable. The ‘cableless’ AM52 does in fact ship with a separate 300mm USB-C to USB-C cable but it’s not integrated into the power bank itself.

The same company also sells the25W Baseus PicoGo AM61 10K Power Bank that is very similar but not quite as slim, and the Baseus Nomos Magnetic 10K Power Bank that, like the PicoGo, has an integrated 45W USB-C cable but slower 15W Qi2 wireless charging. Its recharge score of 166% is close to that of the 25W PicoGo. As it is priced similarly to the 25W PicoGo, the newer model makes more sense.

• Capacity: 38.5Wh (10000mAh)
• Input charger: USB-C (20W)
• Output charger: Wireless (15W Qi2) & USB-C (27W)
• Macworld Recharge Test Score: 170%
• Weight: 8.8oz (250g)
• Dimensions: 4.2-x-2.7-x-0.8 inches (107-x-69-x-20mm)
• Colors: White, Black, Blue, Green

Around the same size as the Ugreen MagFlow power bank, reviewed above, the Anker MagGo Power Bank (10K) didn’t quite match that battery pack in terms of recharging but was still impressive—around the same as the Baseus Nomos.

It is certified for the Qi2 standard and so supports 15W wireless charging. This works with all MagSafe-supporting devices: from the iPhone 12 to 17. (Note that the iPhone 16e doesn’t officially support magnetic charging.)

The EcoFlow RAPID has a slightly more powerful cabled charging spec (30W vs Anker’s 27W) but the difference is negligible. We like the integrated USB-C cable included with those power banks, but any decent USB-C charging cable can be used with the MagGo to fast wire-charge an iPhone.

Aside from fast wireless charging, the Anker boasts an easy-to-read digital display that shows you exactly how much charge is left in the battery pack. Seeing the actual percentage is much more useful than the traditional four LED lights seen on most power banks. It also features a solid pull-out stand at the back.

• Capacity: 39.1Wh (10000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (25W Qi2.2) & USB-C (35W)
• Macworld Recharge Test Score: 171%
• Weight: 7.7oz (220g)
• Dimensions: 4.3 x 2.8 x 0.78 inches (110 x 71 x 20mm)
• Colors: Black

The Sharge Icemag 3 has a cool name and is certainly one of the coolest-looking magnetic power banks we’ve seen. It even has a little RGB light show going on. They don’t mean much but they do look pretty.

At 25W it’s super fast for iPhone 16 and 17, and it maintains power output throughout by having built-in active cooling. Note. though. that this fan is quite noisy in oepration but it should mean more reliable faster charging. Older iPhones will charge at a more sedate 15W.

In our tests it performed well—not the very best but a respectable 177% score.

It has a built-in USB-C cable and a kickstand so ticks all the right boxes in terms of functionality.

• Capacity: 36.5Wh (10000mAh)
• Input charger: USB-C (15W Qi2)
• Output charger: Wireless (15W Qi2) & USB-C (30W)
• Macworld Recharge Test Score: 165%
• Weight: 8.5oz (240g)
• Dimensions: 4.1-x-2.6-x-0.6 inches (103-x-67-x-17mm)
• Colors: Black, Rose Gold

This power bank stands out with its Aramid Fibre weave—a high strength material that is more resistant to heat, cuts and abrasion than other cases and is often used in protective clothing and aerospace parts.

The rose gold color also looks rather nice. Benks doesn’t call it that (or anything) but that’s how it looks with a pleasing weave pattern.

It’s Qi2 so capable of 15W charging—no longer the fastest but what was until recently the cutting edge of wireless power. It scored a decent 165% in the Macworld recharging tests so will give you over 1.5 charges before it, too, needs filling up—which, by the way, it takes its time doing as the 15W input power is less than on other power banks.

Benks also offers an equally tough and super-slim 5K Aramid Fiber model, although it is only MagSafe Compatible so a slower charging experience at 7.5W. The 10K model is Qi2 so faster 15W charging power.

• Capacity: 38.5Wh (10000mAh)
• Input charger: USB-C (18W)
• Output charger: Wireless (7.5W), USB-C (20W) & USB-A (18W)
• Macworld Recharge Test Score: 150%
• Weight: 9.1oz (258g)
• Dimensions: 5.25-x-2.6-x-0.65 inches (133-x-66-x-17mm)

While a wireless charging pad saves you the bother of carrying a cable around to charge your phone from a power bank, you still need a wall charger to hand to recharge the power bank itself… but not with the PhoneSuit Journey Mag, which features foldable North American plug prongs so you can plug the battery pack straight into a power socket. While plugged in, the power bank can charge the attached iPhone wirelessly at the same time as recharging the battery pack.

Two further USB ports are also handy. The USB-C port can charge at 20W, so much faster than the 7.5W MagSafe-compatible wireless charging pad—but you will need a USB-C cable in this instance: USB-C to Lightning for iPhones older than the iPhone 15, and USB-C to USB-C for the 15, 16 and 17. The USB-A port can charge another device at up to 18W.

The 10000mAh battery capacity allowed us to charge a faded iPhone to 100% and then again another 50%, which is about average for this size battery.

• Capacity: 19.35Wh (5000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (15W) & USB-C (30W)
• Macworld Recharge Test Score: 70%
• Weight: 6.4oz (180g)
• Dimensions: 4.3 x 2.8 x 0.6 inch (108 x 70 x 14mm)
• Colors: Gray/silver

5K battery packs are slim enough to clamp to your iPhone and still slip into your pocket. While 10000mAh power banks boast larger re-charging capacity, if you want a slightly smaller and lighter battery pack with a stand, we recommend you choose between this EcoFlow RAPID 5K power bank—the smaller sibling of our recommended best 10K magnetic power bank—and one of the latest slim portable chargers reviewed below.

Where the 5K EcoFlow Rapid gets the overall nod—especially for owners of the iPhone 15, 16 and 17—is its built-in USB-C cable. No other 5000mAh wireless power bank we have tested has the handy integrated cable. Several of our favorite 10K battery packs have built-in cables but this is the first 5K power bank to boast one. Even if you have an earlier Lightning iPhone, the integrated cable can be used to top up the power bank itself.

It features 15W Qi2 wireless charging when clamped to the back of an iPhone, and can be charged with a cable at a top 30W speed. You can find faster 25W 5K power banks reviewed below, and also thinner models with higher recharge scores but the EcoFlow offers a greater mix of features with its integrated cable and kickstand.

• Capacity: 18.5Wh (5000mAh)
• Input charger: USB-C (15W)
• Output charger: Wireless (15W) & USB-C (20W); 22W combined
• Macworld Recharge Test Score: 89%
• Weight: 4.1oz (116g)
• Dimensions: 4.1 x 2.8 x 0.27 inch (103 x 70 x 6.8mm)
• Colors: Titanium Gold, Titanium Black, and Titanium Silver

This semi-solid-state battery promises to be more sustainable and safe than conventional Lithium-ion rivals. At 6.8mm, it’s easily the slimmest magnetic power bank we’ve tested, and it performed the best of any 5K power bank too.

Solid-state electrolytes are replacing flammable liquid electrolytes with more stable, efficient materials that allow for smaller, more compact, and safer battery designs. Semi-solid-state cells reduce flammable liquid to a fraction of that found in standard lithium-ion batteries.

It’s not all about size—these batteries are safer and should last significantly longer with a greater number of cycles before the battery degrades.

In our battery recharge test the BMX SolidSafe Air 5K achieved an impressive score of 89%, among the highest of all the magnetic wireless power banks we have had in the Macworld Labs.

The SolidSafe Air features the usual four LED battery indicator lights. If you want a display with more detail, its plain (non-Air) BMX SolidSafe sibling (available in Black, Blue, Silver or Orange) boasts a great digital screen that is much more informative. That model also has a short USB-C cable attached: it’s not built in but is tied to the power bank on a tough thread.

• Capacity: 19.6Wh (5000mAh)
• Input charger: USB-C (20W)
• Output charger: Wireless (15W) & USB-C (30W)
• Macworld Recharge Test Score: 90%
• Weight: 4.3oz (122g)
• Dimensions: 4 x 2.8 x 0.31 inches (102 x 70 x 8mm)
• Colors: Black

The Zens Semi Solid State 5K Powerbank matches the Ugreen 5K MagFlow Air with the best performance the best we’ve seen in our battery recharging tests, achieving a Macworld Recharge Test Score of 90%. While that’s only 1% more than the BMX SolidSafe Air 5K, reviewed above, and 2% higher than the Statik State 5K Power Bank, reviewed below, it beats the Ugreen by being a little slimmer (8mm vs 8.6mm) and faster at 25W (vs 15W).

Using a semi-solid electrolyte helps this portable charger hit such a high recharge score and remain thin and lightweight with a higher energy density in a compact design. This newer battery structure also enhances stability and durability with improved thermal control, greater resistance to shock and temperature changes, plus a longer lifecycle with sustained performance over more charge cycles.

The 10K Zens Semi Solid State 5K Powerbank (unsurprisngly thicker at 14mm but still thinner than most 10K portable chargers, and heavier at 199g) also performed well in our tests with a score of 181%.

• Capacity: 19.6Wh (5000mAh)
• Input charger: USB-C (20W)
• Output charger: Wireless (15W) & USB-C (20W)
• Macworld Recharge Test Score: 90%
• Weight: 4.48oz (127g)
• Dimensions: 4.1 x 2.7 x 0.53 inches (105 x 70 x 8.6mm)
• Colors: Gray, Blue, White

Like its 10K sibling, the 5K MagFlow Air performed the best we’ve seen in our tests, achieving a Macworld Recharge Test Score of 90%. That matches the same score as the Zens Semi Solid State Powerbank reviewed above and is impressive beating the two semi-solid-state battery packs despite not being solid state itself.

Its 15W wireless charging speed isn’t the very fastest on the market but it’s standard for 5K magnetic power banks, and no slouch with some reviewed here merely 7.5W.

This Belkin BoostCharge Pro Power Bank 5K + Stand impressed in our recharging tests, recharging a faded iPhone 16 Pro by 79% compared to 70% by the 5K EcoFlow RAPID 5K and 68% for the Ugreen 5000mAh Magnetic Wireless Power Bank. Only the Ugreen MagFlow Air 5K (90%), BMX SolidSafe Air (89%), and Statik State 5K Power Bank (88%) beat it and Kuxiu S2 Solid-State Power Kank matched it.

The Belkin’s kickstand is easy to use and feels robust, and the battery pack itself is marginally smaller than the Ugreen. The $49.99 Torras MagStall Power Bank is a little slimmer but wider and boasts a stand/finger-grip, although recharges to a slightly lesser extent.

It features 15W Qi2 wireless charging when clamped to the back of an iPhone, and can be charged with a cable at 12W, which is not as speedy as some power banks that have 20W or even 30W USB-C ports.

Check here first: While Belkin and Amazon offer a choice of Black or White, and the Apple Store now has an exclusive set of new colors, including a brighter Pink, Deep Purple with a red stand and a fetching Teal with a yellow stand.

• Capacity: 19.25Wh (5000mAh)
• Input charger: USB-C (18W)
• Output charger: Wireless (7.5W) & USB-C (20W)
• Macworld Recharge Test Score: 88%
• Weight: 5oz (131g)
• Dimensions: 4.1 x 2.8 x 0.45 inches (104 x 70 x 11.5mm)

This is a Semi Solid State (SSS) power bank so offers greater durability and capacity plus all-important safety on the more traditional liquid electrolyte batteries. It’s likely that SSS power banks represent the next stage in charging technology not just for travellers but all of us on the move.

The Statik State 5K Power Bank may not be the smallest power bank we’ve tested but it’s pretty tiny all the same, and it is the overall winner in our 5K magnetic power bank recharging tests, scoring 88%—just a marginal 2% below our highest scorer, the Ugreen MagFlow Air 5K.

Its only real downside is the slow wireless charging at just 7.5W compared to the superior 15W and 25W power banks reviewed here. If you aren’t after the fastest recharging times, this is a solid choice and gets very close to offering a full battery recharge.

• Capacity: 19.35Wh (5000mAh)
• Input charger: USB-C (20W)
• Output charger: Wireless (15W) & USB-C (20W)
• Macworld Recharge Test Score: 77%
• Weight: 4.3oz (122g)
• Dimensions: 4 x 2.8 x 0.34 inches (102 x 71 x 8.6mm)
• Colors: Gray, Black, and White

Most people carry their power bank around with them, and there’s none better in a small bag or pocket than the super skinny Anker Nano MagGo 5K Slim, the a super-slim magnetic power bank. Only the BMX SolidSafe Air 5K is thinner (at 6.8mm). It’s the little sibling of the 10K Slim reviewed above.

The Anker Slim performed excellently in our recharge tests, boosting an iPhone 16 Pro from 0% to 77%. Charging speeds were impacted by the heat, which is caused by the smart temperature control that slows things down when they get hot.

• Capacity: 19.25Wh (5000mAh)
• Input charger: USB-C (20W)
• Output charger: Wireless (15W) & USB-C (20W)
• Macworld Recharge Test Score: 80%
• Weight: 4.3oz (122g)
• Dimensions: 4-x-2.8-x-0.36 inches (102-x-71-x-9.1mm)
• Colors: Dune, Slate

At just 0.36 inches thick the Twelve South 5K PowerCapsule is one of the slimmest magnetic power banks we’ve tested. Only the BMX SolidSafe Air 5K Solid-State Qi2 (0.27 inches) and Anker Nano 5K MagGo Slim Power Bank (0.34) are thinner; both are reviewed above.

The semi-solid-state BMX scored a very high 89% in our recharging tests, and the PowerCapsule was also impressive at 80%.

We also like the Twelve South PowerCapsule for its sandy Dune color and the fact that it feels great to touch, being crafted in sustainable cactus leather.

There’s a 10K PowerCapsule measuring the same dimensions except for height, which at 0.61 inches (15.5mm) makes it one of the thinnest 10K power banks but not as slim as the 5K; you can see the physical difference above with the 10K PowerCapsule at the top. It scored a decent 165% in our recharging tests.

• Capacity: 18Wh (5000mAh)
• Input charger: USB-C (15W)
• Output charger: Wireless (10W) & USB-C (20W)
• Macworld Recharge Test Score: 85%
• Weight: 4.6oz (132g)

We tested the Titanium version of the UAG SRGE Slim 5K Power Bank with Stand. Not only does it look very smart—as all UAG products tend to—but it impressed in our recharging tests, getting an iPhone 16 Pro from 0% to 85%. Only the semi-solid-state Statik State 5K Power Bank performed better (88%), and that lacks the stand on this UAG power bank and is rated at just 7.5W.

This power bank is rated at 10W wireless, which is faster than 7.5W but noticeably slower than the 15W and 25W power banks also reviewed here. As long as you’re not in an awful hurry, the recharge capacity makes up for the speed.

UAG

UAG has some versions in camo and floral patterns, but without the stand.

• Capacity: 18Wh (5000mAh)

There’s an interesting battle for the crown of smallest, slimmest and lightest magnetic battery pack between three of the power banks reviewed and tested here

The Baseus PicoGo 5K is a tiny bit shorter and less wide than the Vonmählen Evergreen Mag but almost exactly the same slim depth and is 13g lighter. It is precisely the same weight (111g) as the Infinacore M3. We think it’s the sweet spot between the three, and is available from Amazon for less than $23.

Recharging our iPhone 16 Pro to 71%, it performed much better in our battery tests than the smallest power bank (Infinacore: 56%) and very slightly better than the slimmest (Vonmählen: 70%), although that will charge faster at 15W compared to the PicoGo’s 7.5W.

There is a larger capacity 10K Baseus PicoGo (4 x 2.7 x 0.6 inches; 6.2oz) that is about the same credit-card length and width but noticeably thicker in depth than the 5K, as you’d expect from a much more powerful battery pack. The 10K version is faster charging at 15W Qi2, and performed well in our tests with a score of 142%.

• Capacity: 19Wh (5000mAh)
• Input charger: USB-C (18W)
• Output charger: Wireless (15W) & USB-C (20W)
• Macworld Recharge Test Score: 79%
• Weight: 6.1oz (174g)
• Dimensions: 3.3 x 2.4 x 0.4 inch (84 x 60 x 11mm)
• Colors: Stainless Black, Natural Titanium

Solid-state batteries (SSB) are a new technology that promise to be more powerful, sustainable and safe than conventional Lithium-ion rivals by using a solid rather than liquid electrolyte. The Kuxiu S2 is actually “semi solid-state” but it’s still the first SSB power bank that we’ve tested. We have since tested the Statik State 5K Power Bank, which performed even better (88%) in our recharge challenge but is slower (7.5W) at wireless racharging.

One of the benefits of semi or solid-state batteries is that you should get as much as twice as many charges from the power bank before it starts to degrade: 1,000 vs a normal power bank’s 500. It should also be more robust and safer to carry and store.

The Kuxiu S2 performed very well in our charging tests, matching the Belkin BoostCharge at 79%. With Qi2 it wirelessly charges at 15W.

It’s not the smallest we’ve tested but also not the largest, although it does tip the scales more than the tinier power banks reviewed here.

Capacity: 19.25Wh (5000mAh)
Input charger: USB-C (20W)
Output charger: Wireless (15W) & USB-C (20W)
Macworld Recharge Test Score: 70%
Weight: 4.4oz (124g)
Dimensions: 4 x 2.4 x 0.35 inch (102 x 70 x 9mm)
Colors: Black, White

Longer and wider than the smallest power bank we have tested, the well-named Infinacore M3 Mini reviewed below, the Vonmählen Evergreen Mag 5000mAh Power Bank however is a slimmer 5K power bank. If you want to shave 2mm off the width of the power bank clamped iPhone sliding in and out of your pocket, then this is a great option—although the BMX SolidSafe Air 5K (68mm) and Anker Nano MagGo 5K Slim (8.5mm) are thinner.

It is also faster than the M3 Mini and Phonesuit Elite Mag Slim at wirelessly charging as it supports Qi2, and in our tests it recharged an iPhone 16 Pro from 0% to 70% before requiring a power-up itself, which easily beats the Infinacore and just shades the PhoneSuit.

• Capacity: 19.25Wh (5000mAh)
• Input charger: USB-C (18W)
• Output charger: Wireless (7.5W) & USB-C (20W)
• Macworld Recharge Test Score: 69%
• Weight: 3.9oz (111g)
• Dimensions: 4-x-2.6-x-0.35 inches (108-x-65-x-9mm)
• Colors: Space Grey

Knowing how much charge is left in your power bank could mean the difference between leaving the house confident that your battery pack is full of juice and finding out too late that it needs a recharge itself.

The Elite Mag Slim from PhoneSuit has a large digital display showing off the exact remaining charge that is more accessible than the usual four LED dots found on most power banks.

This battery pack is also notable for its slimness, which is equal to the Vonmählen Evergreen Mag, reviewed above. The Vonmählen power bank narrowly beat it in our tests but certainly not significantly so, but it does charge faster wirelessly (15W vs 7.5W) than the PhoneSuit.

The PhoneSuit Elite Mag Slim Pro is a 10K version, with a recharge score of 149%, and the same bright easy-to-read display for just $10 more but deeper (0.5in vs 0.35in).

• Capacity: 19.25Wh (5000mAh)
• Input charger: USB-C (20W)
• Output charger: Wireless (7.5W) & USB-C (20W)
• Macworld Recharge Test Score: 56%
• Weight: 3.9oz (111g)
• Dimensions: 3.3 x 2.4 x 0.4 inch (84 x 60 x 11mm)
• Colors: Stainless Black, Pearl Silver

If you want a magnetic power bank that’s super small, the Infinacore M3 Mini Wireless Power Bank is a slimmer, shorter and narrower and 25% lighter than most battery packs tested here. The PhoneSuit Elite Mag Slim and Baseus PicoGo power banks, also reviewed here, are equally light. You’ll hardly notice any of them in your pocket or bag.

The compromise is in recharging performance—in our tests the M3 Mini resurrected a faded iPhone 16 Pro by 56%, which might be enough for several hours service but is notably weaker than the other battery packs tested here.

If you want the security of a power bank in your handbag or backpack, then this takes up little space and weighs next to nothing, while offering just enough juice to perk up your fading iPhone.

• Capacity: 38.7Wh (10000mAh)
• Input charger: USB-C (30W)
• Output charger: Wireless (25W Qi2.2) & USB-C (30W)
• Macworld Recharge Test Score: 170%
• Weight: 9.05oz (257g)
• Dimensions: 4.1 x 2.7 x 0.9 inches (105 x 69 x 22mm)
• Colors: Black, Cosmic Orange

The Kuxiu K1 Ultra bills itself as a 3-in-1, and certainly can charge iPhone, AirPods and Apple Watch but not all wirelessly at the same time. Let’s not knock it, though, as this is a super Qi2.2 iPhone magnetic power bank that can wirelessly charge your iPhone at the very fastest speed.

The other multi-device magnetic power banks reviewed below are limited to 7.5W wireless iPhone charging. That will take around 90 minutes to charge an iPhone to 50%, where this power bank’s 25W wireless output reduces that charging time to a mere 30 minutes. Noe that only the iPhone 16 and 17 benefit from 25W wireless charging; older iPhones will charge at 15W using this power bank.

The back section of the K1 Ultra cleverly clicks round like a rotated Rubik’s Cube to show off its Qi module that can charge Watch or AirPods at 5W. There’s also a spare USB-C port to enable a third device to be charged if you have a cable handy. A handy kickstand is also available.

There’s a lovely Cosmic Orange model, which is available via Amazon or direct. Otherwise, you can choose the Black model.

If 15W is all you need—0-50% charging in around 45 minutes—Kuxiu offers the K1 Pro for a lower price, although we’d recommend you consider spending the extra so you’re ready for your next iPhone upgrade.

• Macworld Recharge Test Score: 235%

Much bigger and meaner than the power banks reviewed above, the Statik SmartCharge Pro can charge through its USB-C and USB-A ports, an iPhone or Apple Watch wirelessly through a magnetic charging pad, and one through the built-in USB-C cable. As a portable power bank you might carry in a bag on your travels, but not in your pocket—it’s one to rest on a table rather than in actual transit.

In our tests, it demonstrated its 15K battery capacity—charging an iPhone 16 Pro nearly two and a half times over. It even recharged a flat 14-inch MacBook Pro to 54%.

Certified Qi2, the iPhone wireless charging pad is rated at 15W. There is an integrated 60W USB-C output cable, as well as a 60W USB-C port and 18W USB-A. It’s not so great at charging multiple devices at the same time—when using all the ports simultaneously they share a maximum 15W output. If you want to get the 60W charging use either the USB-C port or cable and have nothing else hooked up to the power bank.

It features built-in U.S. plug prongs so can be connected straight into a power socket rather than requiring a separate USB-C charger. You can quickly charge the power bank plugged into a wall AC socket, but during recharging the output is reduced to 20W on the port and cable until the battery is at 100% when the charging returns to 60W. If you need a higher-wattage standalone USB-C wall charger, check our reviews of the best USB-C chargers.

The U.S. plugs are fine for users based in North America, but not for international users, so there are U.K., E.U, and AU/NZ plug adapters included making it work in those countries and as a travel companion.

Statik has a non-Pro version, the 10K SmartCharge Gen 2, which features two integrated 15W USB-C cables, plus 20W USB-C and 22.5W USB-A ports. In our tests, it was very close in battery charging power to the top scorers—charging an iPhone 16 Pro nearly twice over. This version isn’t available in the Pro’s bright orange color.

The first version of SmartCharge Gen 1 has one USB-C for iPhone 15/16/17 and a Lightning cable for older iPhones. if that suits you better, Amazon still has stock at the time of writing.

Another plug-in-the-wall power bank option is the Infinacore P3 Pro, pictured above, which costs $129 / £102, and can charge four devices at the same time, including an iPhone at 15W Qi2. It lacks the integrated USB-C cable found on the Statik power bank but as it plugs directly into a wall power socket you won’t need to carry a cable to recharge the power bank itself. Like the Statik battery pack, it comes with U.K., E.U, and AU/NZ travel adapter plug heads. As well as the Qi2 charging pad, there are two USB-C ports and one USB-A. The P3 Pro also boasts an excellent display, showing charging speed, battery status, temperature, and charge time remaining.
