What You Get: Anker 511 Charger (Nano 3, 30W), welcome guide, our worry-free 24-month warranty, and friendly customer service (cable not included). 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. 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). 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. Small Yet Powerful: By swapping out silicon for Gallium Nitride (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.
