Apple doesn't publish its battery capacity, but teardowns have shown that the iPhone 15 has a battery with around 3,350mAh of battery life. That means a 10KmAh battery can charge that phone twice ... almost. You may not get to 100% the second charge, but you'll be in the 90% range. The use of USB-C for the single input/output port is a little weird given the target market, and you’ll need a fast USB-C charger and a USB-C to Lightning cable to make the most of the device. What’s more, the wired charging isn’t super-speedy; our Android test smartphone only recovered by 11% from a 15-minute charge. But if you’re an iPhone user looking for a light and convenient portable charger, the Anker 622 is almost perfect for the role. Now that you know a little bit about power bank maintenance and the most common ways they fail, we can explore how to narrow down the issue. You need fast power: This is a very slow charger, whether wired or wireless, so it's better for casual charging while you sip your water and read a book. We wish there wasn't such an easy answer to this question, because competition is better for everybody, but Anker is making the best power banks right now by far. It offers the best power-to-weight ratio, the fastest charging, and the most useful features.

In terms of charging, this massive power bank can charge an iPhone 15 more than five times. It can charge a big Galaxy S23 Ultra's 5,000mAh battery three-and-a-half times. Best of all, it charges at the fastest speed available on most of your favorite phones (excluding Oppo/OnePlus's unusual SUPERVOOC battery). There are also cool additional features to consider. Our favorite power bank has a built in charging plug so it can go right into a wall outlet. Some power banks have data about your charging devices. Some are just super small and cute. Which power bank is the best quality? Anker batteries also look great and are built with high quality parts. The display on our best battery for power users is bright and sharp OLED display, totally unnecessary for a power bank, but that's what makes Anker the best. It far exceeds our expectations of what's necessary to make power banks that are great. The two USB ports mean that you can charge two devices at once. It offers pass-through charging and cleverly, the efficient circuitry prioritizes charging your connected device first and then funnels the extra energy to your IonBank itself at the same time, so you get the optimum run time out of the time you have spent plugged in.Considering that today's kids are probably more interested in an iPad than a remote control car, it seems an ideal way of Duracell bringing their brand a bit further into the future. There are plenty of other power bank makers around, and most of them have not caught up to the faster charging speeds available on the iPhone 15 family, let along even faster Android phones. Except for unique form factors or serious bargains, we stayed away from recommending power banks from reputable makers if they couldn't charge at 2023 speeds. Running out of juice, and therefore being unable to access Google Maps, is no longer a viable excuse for standing someone up or missing a conference call.

It's a charming look though the plastic case can't help but feel a little less premium than some of the other devices on this list. Still it feels sturdy and has a nice bright set of lights on the side so you can always see how much power you've got left in it. Consider the price. We’ll dive into a lot more detail on the price of GOJI G6P4WL20 Portable Power Bank shortly, but in terms of quality, the obvious advice here is ‘you get what you pay for’. It’s really just being aware that if you’re buying the cheapest of the Mobile accessories from Currys PC World you might not expect the same level of quality as you’d get from a decent quality product like GOJI G6P4WL20 Portable Power Bank.Why we like it: The best looking of the lot – and capable of providing a MacBook Pro with a 40pc power boost. So, brains and brawn. Wise deployment of airplane mode – when you're watching a set, sleeping or charging – will go a long way. Everybody on our gift list who got a new iPhone is going to get an Anker Nano Power Bank (22.5W) this year. This cute little charger is perfectly sized to sit beneath your favorite smartphone, plugged into the USB-C port with a little plug that opens out or hides away for a sleek look. Versatility is also worth considering – for example, can you use the charger for multiple devices? What devices is it compatible with? Does it offer pass-through charging (which means you can charge the bank itself, while using it to charge a connected device)? That app is essential because there's a Find My feature built into the battery. It doesn't work like an AirTag over UWB, it's only Bluetooth, but it's useful if you misplace your battery in your office (or you have multiple batteries, like I do).
