Pocket-Sized Magnetic Power

The Anker 621 Magnetic Battery (MagGo) is a 5000mAh power bank that snaps magnetically to the back of compatible iPhone 12, 13 and 14 series models. It is built for users who want cable-free top-ups while keeping the phone in hand. The slim MiniCell design lets it sit in a pocket or purse without adding bulk.

Thermals Noise and Power Draw

The lithium polymer cell recharges through a USB-C port using the included 60 cm cable and a separate adapter of at least 12W output. MultiProtect safety technology monitors temperature and current during both wireless and wired charging. No fan or active cooling is present, so operation stays silent.

Bundled Cable and Warranty

A 23.6 in USB-C to USB-C cable is supplied for recharging the power bank or for wired charging of other devices. The package also includes a welcome guide and a 24-month warranty. The PU leather coating protects the phone from scratches while the magnets hold firm.

Questions about this item

How do I attach the Anker 621 Magnetic Battery to my iPhone 13 and what alignment step do users often miss?

Snap the MagGo unit onto the back of the iPhone 13 or 12 series; the ultra-strong magnets pull it into the exact charging position, eliminating the misalignment that causes wireless charging to drop.

What part of the Anker 621 Magnetic Battery will need replacement first and when?

The internal 5000 mAh lithium-polymer cell is the only consumable; after hundreds of charge cycles its capacity will gradually fall below useful levels, at which point the whole power bank is replaced.

What thermal or power limit appears first during continuous wireless charging with the Anker 621?

Sustained wireless output is capped by the battery's 5000 mAh capacity; once the stored energy is depleted the unit stops charging until it is recharged via the USB-C port with a 12 W or higher adapter.
