Wireless charging has become popular because it allows you to power up compatible devices without a cable. Qi is the dominant standard for compatible Android phones (up to 18W) while Apple iPhones rely on MagSafe charging (up to 15W). iPhones will charge wirelessly on Qi chargers, but only at 7.5W. We expect this competition will heat up next year as more power bank makers catch up and make faster charging batteries. Until then, Anker is the dominant brand, and if you want the best it's an easy choice. How many times can my power bank charge my phone? The best power banks we have tried have all come from Anker, but that doesn't mean Anker is the only brand you should consider. All of the power banks on this list passed our testing, traveling with us on the road and powering our devices at home. Anker is the best, but these batteries from Baseus and Otterbox performed well.

In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty. Alignment Method: Traditional wireless charging requires a precise placement on the charging pad, while MagSafe chargers use built-in magnets to automatically align your iPhone, ensuring consistent optimal charging. The iWalk power bank also boasts a sizeable battery, with 2.2Wh (6000mAh) capacity. It recharged our test iPhone 13 Pro to 100% and then another 5% above that, so, in reality, a full charge with a little over for expected battery drain if left sitting in your bag for a few days. And it will charge a non-Pro 12, 13, 14 or 15 even further. Our favorite power bank has a 10,000mAh battery, and the Samsung Galaxy S23 Ultra has a 5,000mAh battery, so the math should be simple, right? It charges twice. Except that's not how it works. Power banks are not 100% efficient, and even though you start with plenty of power, a lot of it is lost in the charging process.

Take it Anywhere

Larger and weightier (2x the nearest rival) than alternatives, the Belkin Magnetic Portable Wireless Charger 10K is more of a wireless charging pad that can also be carried around as a power bank. What it does offer is a massive battery capacity of 92.5Wh (25,000mAh), which should be enough to get you through a weekend festival. If you spend a lot of time outdoors, this is among your best choices for keeping your devices running while off of the grid. In other words, it’s camping approved. The QiSa Solar Charger can use the sun to recharge itself, supports both wired and wireless charging, and even has a built-in flashlight. Best of all, it offers a massive 38,800mAh capacity. Who It's For MagSafe chargers do more than wirelessly charge your phone. They can provide utility, versatility, and even help you declutter your workspace. The best MagSafe Chargers often have the ability to charge multiple devices at once. This is great for someone who has an iPhone, Apple Watch, and AirPods. Instead of taking up three wall or surge protector outlets, you can conveniently charge all three devices with a single MagSafe charging stand.

You can buy the Tylt Bottle with just a power bank attached, but our review sample from AT&T had the full wireless charging treatment. It's easy to set up a phone to charge while studying, working out, or working away from home: all places we take a water bottle and need a full phone battery. Courant Mag:2 Essentials / Classics: Courant’s same elevated formula but this time in a 2-in-1 charger for your phone and earbuds. If you’re the type that obsesses over mid-century modern stylings like hairpin legs and Eames chairs, here’s your (non-MagSafe) magnetic charger. It’s even sold at the Herman Miller store — need I say more? 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. The good news is that the LED charge percentage indicator lets you know the remaining juice left in the charger. The bad news is that it is placed on the same side as the magnetic connection so that your phone covers up the display while attached.

Easy Magnetic Attachment

You want a more portable option: Because of its combo nature, the Anker 733 is a bit bulky and cumbersome, but if you use it both ways, it's worth the trade-off in size to have such a useful device. The Anker battery charges wirelessly at 7.5W–faster than Apple’s 5W charge, although the Apple battery can use the wireless Qi and cabled USB-C power simultaneously to speed charging at up to 15W. Charging Speed: The higher the watts your power bank can deliver, the faster your phone will charge. A five-watt capacity is pretty standard, but some can go as high as 15. You will need a fast USB-C charger to power up the power bank itself, with a maximum 65W charging input. Larger batteries with higher capacities might include a multitude of ports to support input and multiple outputs at the same time. You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common.
