The Anker 321 MagGo is a 5,000mAh magnetic power bank that snaps onto the back of MagSafe iPhones and charges them wirelessly at up to 7.5W. Its slim, lightweight body and strong magnet make it a pocketable top-up for a day out rather than a full recharge. Anker says the cells hold about 90% capacity after 20 months, well above the 60% industry norm. It only works with MagSafe-compatible cases and wireless charging is slow, so it trails higher-capacity or wired rivals on speed and total charge.

The Anker 321 MagGo Battery (PowerCore Magnetic 5K), model A1616, is a slim, lightweight magnetic power bank with a 5,000mAh capacity. It snaps onto the back of an iPhone 12, 13 or 14 series phone, or later, for charging on the go.
A magnetic attachment holds it securely to the phone. It works through MagSafe cases, so the case can stay on while charging. It does not work with non-magnetic cases, such as Otterbox Defender cases. Magnetic charging provides up to 7.5W of power.
The battery is designed to keep 90% of its capacity after 20 months of use. The 5,000mAh figure is the total nominal rated capacity of the internal battery cells.
