The best iPhone power bank in 2025: portable chargers for your Apple device

The best iPhone power bank is a very important investment. Because this could be a real lifesaver when your iPhone runs out of juice, whether you've been on a long trip, working remotely, or just forgot to charge your phone.

Most iPhone power banks offer between 5,000mAh and 10,000mAh of power, which is normally enough for one to two full charges. If you're heading into the wilds for a weekend, or need to keep a laptop charged as well, you might need a larger one with 20,000mAh or even 25,000mAh capacity. These will be heavier and bulkier, as well as pricier, so there's a balance to be struck between capacity and portability.

To compile this list, we've drawn on our experience both testing power banks as tech journalists, and using them in our daily work. We've also included links to full reviews if you want to read about the different models in detail.

Best iPhone power bank overall

This is basically the Swiss Army knife of portable chargers. With its Qi2-certified 15W wireless charging and zippy 27W wired option, it's designed to juice up your iPhone quickly and efficiently. And that's not all. It also has a built-in display, which provides a clear readout of remaining battery life and estimated charging time. The clever flip-out stand is another winner, allowing you to prop up your phone for video watching or FaceTime calls while it charges.

While it's not the slimmest power bank on the market, its 10,000mAh capacity offers ample recharges for most iPhones. The premium build quality and Anker's reputation for reliability help justify the fact that it's quite expensive.

Best compact and light iPhone power bank

Want something more portable than number one on our list, which weighs 250g? The Belkin magnetic power bank weighs 100g less, but it's still very capable. We especially like its a nifty built-in stand; a way to prop up your phone for videos, keep tabs on notifications, and even dive into video calls hands-free.

Though it might not pack the biggest battery punch out there, this power bank manages to give your phone almost a full recharge when needed. The smaller battery size isn’t a flaw; it’s what keeps it slim, compact, and light and doesn’t weigh you down during long days.

The best slim iPhone power bank

If you want the convenience of Qi2 wireless charging but in a slimmer, more pocketable package than our top pick, the Anker MagGo 10K Slim is an excellent choice. At 200g, it's 50g lighter than the original MagGo, and at just 14.7mm thick, it slips easily into a jacket pocket.

The liquid silicone covering provides excellent grip, while the premium metal frame and matte finish give it a quality feel. Battery LED indicators keep you informed of remaining power, though a small display would have been preferable. The raised border around the Qi2 charging area is a thoughtful touch that helps with phone alignment.

With 15W wireless charging and 30W wired charging via USB-C, it delivers fast charging speeds. In testing, it charged an iPhone 12 from 0% to 50% in 45 minutes wirelessly, or just over 30 minutes with a cable. The power bank itself recharges in around 125 minutes. While it lacks the flip-out stand of the original MagGo, this is the trade-off for improved portability.

Best power bank with USB-C and USB-A

This power bank from Ugreen supports MagSafe, does a great job of snapping magnetically into place, and the 10,000mAh battery is impressive. In my tests, the Ugreen power bank kept my iPhone 15 Pro Max topped up for around two full days, recharging the phone's full capacity around one and a half times.

The battery also comes with a versatile built-in foldable kickstand, which you can use to position your phone for a comfortable viewing angle. You also get a USB-C port and a USB-A port for older devices, which allows you to charge your phone or perhaps a camera. The power bank can also use this USB-C port to fast-charge itself back up in just a few hours.

Best high-capacity iPhone power bank

If you need serious charging power for your iPhone, laptop, and other devices, the Anker Laptop Power Bank is the solution. With a whopping 25,000mAh capacity, it can charge an iPhone 16 Pro around seven to eight times, or a MacBook Pro (M2) approximately four times before needing a recharge itself.

The standout feature is the built-in cables: a USB-C cable that doubles as a carry handle, plus a retractable USB-C cable that extends from the top. Both are beautifully implemented, with the retractable cable featuring a magnetic strip that keeps it neatly tucked away when not in use. You also get a USB-C port and a USB-A port for additional flexibility.

The 100W maximum output means genuinely fast charging: a 16-inch MacBook Pro reaches 50% in just 33 minutes, while an iPhone 16 hits 50% in 25 minutes. The large TFT display provides real-time information on battery level, input/output power, and recharge times, all clearly visible even in bright daylight.

Yes, it's heavy at 592g, but the robust plastic casing is built to last and can be thrown in a bag without worry. The built-in ActiveShield 2.0 technology monitors temperature millions of times per day, ensuring safe operation. For photographers working remotely or anyone who needs to keep multiple devices charged throughout the day, this is an invaluable tool.

Best small iPhone power bank

The switch to USB-C charging for the iPhone 15 and 16 is indeed a game-changer, making the Anker Nano 22.5W power bank an enticing solution to just slip into a pocket at all times. With its 5,000mAh capacity, it packs just the right punch to give your phone that essential boost precisely when it's needed, although it isn't going to give you more than one full recharge. However, the 22.5W charging capability ensures a swift charge, so you can get your phone topped up faster.

What's truly convenient is the built-in pop-up USB-C port, eliminating the hassle of carrying an extra cable. It's the kind of versatile gadget that feels like a must-have for every jacket pocket, ready to step in whenever your phone calls for a pick-me-up.

How to choose the best iPhone power bank

The best iPhone power bank for you is the one that suits your charging style best. If you prefer wireless charging, then there are a number of power banks on this list that would suit you better. Wireless charging is much more convenient, but it is much slower than wired charging, and wireless power banks tend to have much lower capacities than wired banks.

If you are happy to charge with a wire, then your choice comes down to how big you want your power bank to be and how often you want to recharge. If want to recharge multiple times then the power bank will be much larger, but it means you'll have to charge the power bank less. If you want a power bank to just keep your phone from completely dying then a smaller power bank will do for emergencies, but might require you to think more about how much power is left in the power bank itself.

How we test iPhone power banks

We test iPhone power banks by trying to use them in our regular daily use of our iPhones, specifically looking at how fast each power bank recharges our phone, and how many chargers can we get out of the power bank before it runs out of juice itself. We can then compare this to the manufacturer specifications, and see how they match up.

We also look at the design and build quality of power banks, rating each power bank on its appearance and durability. Finally, we assess power banks' convenience in use, is it easy to understand, and does it have all the necessary parts.
