Is the Anker 621 MagGo worth it?

It is worth it if you want a slim, cable-free top-up for a MagSafe iPhone. If you need a full recharge, a wired pack with more capacity is a better fit.

How fast does it charge?

Wireless output is 5W, which is slow. Expect a partial charge over an hour or more, not a fast full recharge.

Which phones does it work with?

It is made for MagSafe iPhones (iPhone 12 and later). Other phones can charge on it but will not snap on magnetically.

The pack comes with a USB-C cable. A wall adapter is not included.

Is $42.99 a good price?

Our take on the Anker 621 MagGo Magnetic Battery

The Anker 621 MagGo is a slim magnetic power bank that snaps onto the back of a MagSafe iPhone and charges it wirelessly, with no cable needed. It is built for top-ups on the go rather than full recharges, and its 5W wireless output is slow compared with wired charging. At $42.99 at Walmart as of November 7, 2026, it sits at the low end of its recent price range, so this is a good moment to buy.
