Anker 621 Magnetic Battery (MagGo) and Anker 511 Charger (Nano 3, 30W)

Smaller Than Ever: Anker's new MiniCell technology delivers identical charging performance with fewer components. This means it's smaller and lighter than ever before.
Pocket-Sized Power: Slim enough to snap to your phone and slip into your pack, purse, or pocket.
Strong Attachment: Equipped with ultra-strong magnets that firmly attach to the back of the iPhone 13 or 12 so you can single-handedly take selfies, make calls, and more.
Charge in a Snap: Align your iPhone and battery with a snap. Say goodbye to disconnection issues caused by wireless charging misalignment.
Small Yet Powerful: By swapping out silicon for GaN we've been able to fit 30W of power into a charger that's just 1.12 inches thick, and 70% smaller than an original 30W charger.
Nano Now Charges Everything: Upgraded with a 30W output so now you can charge your earbuds, phone, tablet, and even your MacBook Air with a tiny charger.
High-Speed Charging: Deliver full-speed 30W charging for iPhone 13 Pro and Pro Max, or power up your iPad Air (5th Generation) to 50% in just 45 minutes. Also supports Samsung Super Fast Charging (25W).
Upgraded Protection with ActiveShield 2.0: Anker's proprietary technology safeguards your devices by intelligently monitoring temperature over 3 million times per day—that's twice as often as ActiveShield 1.0.
