Pocket-Sized Power for Apple Devices

The Anker 621 is a 5,000mAh portable charger with a foldable built-in Lightning connector. MFi certification ensures safe, reliable charging for iPhone 12, 13 and 14 series models. Its compact 3.03*1.45*0.98 inch form factor and 0.22lb weight make it easy to carry in a pocket or small bag. The 12W output delivers up to 20 hours of extra video playtime on an iPhone 14 Pro Max.

Check Your Case and Port Needs

The foldable Lightning plug requires direct contact, so cases thicker than .19 inch (4.9 mm) must be removed before charging. A USB-C port recharges the power bank itself; simultaneous pass-through charging is not supported. A 1.9 ft USB-A to USB-C cable is included for recharging the unit. Verify your device uses Lightning, as USB-C iPhones are not compatible with the built-in connector.

Ideal for Daily iPhone Top-Ups

Suits iPhone owners who want a cable-free emergency charge for a single Lightning device. Not for users needing to charge multiple devices at once, power USB-C phones, or use thick protective cases without removal. Buyers who want more capacity or pass-through charging should look at larger multi-port models.
