Our take on the Anker 621 MagGo Battery (MagGo Power Bank)

The Anker 621 MagGo Battery is a slim magnetic power bank that snaps onto the back of a MagSafe iPhone and charges it wirelessly. It is built around a 5,000 mAh cell, so it adds roughly one full phone charge rather than several. The magnetic hold is strong and the pad aligns itself, which makes it a pocketable top-up for commutes and travel. Against larger magnetic banks it trades capacity for a thin, light body, and owners say it is best treated as a daily top-up rather than a weekend power source.

Questions and answers

Does the Anker 621 MagGo work with non-MagSafe phones?
It charges any Qi phone, but the magnetic hold only aligns with MagSafe iPhones. Other phones need to be held in place or charged by cable.
How many charges does it add?
The 5,000 mAh cell adds roughly one full charge to a typical iPhone. Expect less on large phones or with heavy use.
Can I charge it and my phone at the same time?
Yes. You can plug the bank into a charger over USB-C while it wirelessly charges a phone, though charging slows.
Does it come with a cable?
It ships with a USB-C cable for charging the bank itself. You do not need a cable to charge the phone wirelessly.
Is it worth it over a larger power bank?
Choose it for its slim magnetic fit and cable-free top-ups. If you need several full charges, a larger bank with more capacity suits better.
