The Anker 621 MagGo is a slim magnetic power bank that snaps onto the back of MagSafe iPhones and charges them wirelessly. Anker's MiniCell design makes it smaller and lighter than most magnetic packs, so it stays pocketable and can be used one-handed while attached. It suits iPhone 12 and 13 owners who want a top-up charge without a cable. Against rivals like the Apple MagSafe Battery Pack, it is lighter and adds a USB-C port for wired charging, though its capacity is modest and it is not built for multiple full phone charges.

Owners rate it highly, praising the compact size, the firm magnetic grip and the convenience of snapping it on without a cable. The main complaints are the limited capacity and slower wireless charging speed.
The Anker 621 Magnetic Battery (MagGo) is a magnetic wireless power bank for the iPhone 13 and iPhone 12. It uses Anker's MiniCell technology, which delivers the same charging performance with fewer components, so the battery is smaller and lighter.
Ultra-strong magnets attach it firmly to the back of the phone. This lets you take selfies and make calls with one hand. The magnets align the phone and battery with a snap, which avoids the disconnections that wireless charging misalignment can cause.
The battery is slim enough to stay attached to the phone and slip into a pack, purse or pocket.
