As much as I like the iPhone, the battery sometimes struggles to make it a day. This is why I like to have a power bank on hand to stay one step ahead of the problem.
The best iPhone power banks are designed to fit right your pocket and provide you a reliable source of power when you’re on the go. A good power bank prioritizes capacity, fast charging speeds, and port options. Power banks with MagSafe technology are even more convenient since it attaches to the back of a MagSafe-compatible iPhone.

Why we like it: At a time when a lot of MagSafe wireless chargers want to become big and bulky, adding kickstands and cooling fans, and lanyards, it’s great to come across a wireless power bank that wants to do one thing — keep my iPhone charged up.
The Sharge CarbonMag 5K does it’s job exceptionally well with a simplistic design. At 120 grams and 8.8 millimeters thin, this is something that feels like it blends in with the aesthetic of the iPhone once it’s snapped onto the MagSafe ring.
Also: Finally, a long-lasting power bank that’s lighter than competing accessories I’ve tested.
On the charging front, you have the option of using a 15W wireless MagSafe for the iPhone and a 20W USB-C port for everything else. There are tiny LEDs on the back of the power bank showing charge levels, charging status, and whether it is switched on. There’s a single button for switching the unit on.
Almost a year on from my first encounter with this power bank, I’m still finding myself turning to this one.
Who it’s for: Someone who wants a small, lightweight, energy-dense power bank that delivers on what it promises.
Who should look elsewhere: This is for small on-the-go top-ups, not big battery recharges.

Why we like it: This is a carbon fiber clad power bank that has it all — it’s ultralight, ultrathin, and waterproof to IP68.
I’ve thoroughly tested this power bank’s dust and water resistance, and it impressively shrugs off both elements.
Also: My favorite power bank for traveling is waterproof and surprisingly lightweight
However, I wish it had port covers for the USB ports to prevent dirt, dust, and water from getting inside. While a quick shake is enough to remove water, extracting dust and sand can be more challenging. In the end, I 3D-printed end caps for it from TPU, and that solved that problem.
Who it’s for: This looking for a decent capacity, high energy density power bank that can deal with the element.
Who should look elsewhere: You’re paying a premium for a power bank that’s ultralight, ultrathin, and waterproof. If you don’t need that, there are cheaper units.

The biggest downer is reaching into your bag and discovering that you have a power bank without a cable. The Belkin Boostcharger removes this possibility with built-in Lightning and USB-C cables. This feature separates it from the competition and impressed many Amazon and B&H Photo reviewers.
This power bank also features passthrough technology, which means you can charge your iPhone with speeds up to 18W while charging the power bank.
This passthrough charging feature might not seem like much, but I’ve found this to be super useful on a desk, a nightstand, and when traveling. It means I can have one small wall charger juicing up the power bank while the power bank is simultaneously charging up other devices. This saves on space and how many power outlets I need, and it streamlines what I need to carry, which is really appreciated when traveling.
The 10,000mAh capacity also means that it’s not too big to be slipped into a pocket or bag.

The Anker Nano 10,000mAh 30W is a power bank with a built-in USB-C cable — a great option for the iPhone 15.
This cable is a decent length at 0.6ft (19cm) and can be used for both charging the power bank and charging other devices. This cable fits through a metal loop on the power bank, keeping it out of the way when not in use and allowing it to be used as a lanyard loop when not in use.
There’s a single button on the top of the unit to turn the power bank on. On the front, a small but exceptionally vibrant display shows the charge level and estimated charge/discharge time.

Why we like it: Some people want as big of a power bank as they can get away with. For portability, this 20,000mAh is about as big as they get.
I like that this MagFlow unit is the built-in cable. This means I can throw my iPhone onto the charging pad and give another device a boost without needing any extra cables.
This offers a lot of choice as well. In addition to the cable, there’s a USB-C and USB-A port.
Who it’s for: This is great for those who roll with an iPhone power user with other things that need charging.
Who should look elsewhere: This power bank is a fairly hefty lump that weighs a just over a pound, so it’ll drag your pocket down.

Here are some factors I suggest you consider when choosing a power bank for your iPhone:
- Size: It’s no good having a power bank if you’re going to end up leaving it at home. Sure, if you’re going off grid for a few days, you’re going to need something big, but most people are looking for something to top up their phone during the day before going home, and for this a power bank with a 5,000mAh capacity is more than enough for a quick top-up.
- Wired or wireless: If you don’t want the hassle of having to carry a charge cable and a power bank, go for a unit that feature wireless MagSafe charging.
- Safety: I test every power bank for a number of safety issues, including checking for overheating in use and whether the case is robust enough to protect the internal batteries. I recommend sticking with name brands and avoiding dollar store power banks.
I chose these iPhone power banks through a combination of extensive research and using the products to charge everyday devices. I paid attention to:
- Customer reviews and ratings: I evaluated personal experiences and ratings of the included products to take note of strengths, weaknesses, and overall customer satisfaction with each battery pack.
- Pricing: I considered battery packs with a varied price range to ensure there is a product for everyone, with most battery packs costing between $20 and $100.
- Renowned brands: I selected battery packs manufactured by trusted and ZDNET-reviewed brands to ensure the recommended picks were of quality and standard.
- Capacity: Battery packs can differ in the amount of power (measured in milliamp hours or mAh) contained in the battery. I used a USB power meter to test the capacity of every power bank listed to ensure that it delivers what it says on the spec sheet.
- Overheating: I used a thermal camera to check for overheating, both when the power back was in use, and when it was being charged.
Some cheap power banks and chargers can harm your smartphone. Overall, though, power banks are safe and work using the same technology as a regular charger. We trust any of the picks above to be quality power banks that won’t damage your iPhone’s battery.
According to the Transportation Security Administration (TSA), portable chargers or power banks containing a lithium-ion battery must be packed in a carry-on bag, rather than in checked baggage. Most airlines allow a power bank with a battery of up to 27,000mAh.
Those cheaper power banks work; however, in my experience, they don’t offer the capacities that they claim and don’t last nearly as long as a decent power bank from a reputable manufacturer, don’t deliver the power stated, and can overheat in use.
The phrase “you get what you pay for” applies to everything, including iPhone accessories. That’s why it’s better to spend more money to get something that’ll enhance your phone’s productivity and last.
A wireless power bank can be very helpful, since you don’t have to remember to bring any cords or cables with you. Just set your iPhone on the power bank and start charging.
They’re not ideal for use while you’re actually traveling, however, since there isn’t a way to secure your phone to the power bank. When flying or driving, your phone could slip off the charger without you noticing, leaving you with a dead or dying phone when you reach your destination. MagSafe power banks are good, but they’re not infallible.
When you’re researching for a power bank, it’s important to consider the capacity, charging speed, portability, if it’s wired or wireless, and safety features. However, a lot of times you can find a lot of helpful information by looking for customer reviews and ratings to gauge the reliability and durability of a power bank. Any of the picks above are expert tested and reviewed by our editors.
It depends on how many recharges you want. A 5,000mAh power bank will give you about two recharges of a standard iPhone, and a little less for the bigger iPhones.
