Anker has released its thinnest MagSafe-compatible power bank, measuring about a third of an inch thick. It’s only got a 5,000mAh battery inside, so you probably won’t get two full iPhone charges with it, but Anker has updated it with 15W Qi2 wireless charging speeds so your phone can charge faster.

It’s currently available exclusively through Apple’s online and retail stores for $49.95 in either blue or white, making it $10 more expensive than the older MagGo 621 Magnetic Battery that Anker still sells through its website. For comparison, the older version of the 5K battery is 0.45-inches thick and only supports wireless charging speeds up to 7.5W.

The bidirectional USB-C port on the bottom of the power bank can charge it or other devices at 20W. However, when both power outputs are in use, wireless charging speeds drop to 5W, while the USB-C port slows to 12W. The battery is compatible with iPhone models going back to the iPhone 12, but it will also work with Android devices that fully support the Qi2 specifications.
