Anker Nano Power Bank Review

Anker Nano Power Bank (5K, MagGo, Slim) is an ultra-thin 5,000mAh Qi2-certified magnetic power bank with 15W MagSafe-compatible wireless charging, just 0.34 inches thick.

As thin as an Apple Pencil, this is the power bank for people who hate carrying a power bank. It snaps onto MagSafe iPhones for genuine 15W Qi2 charging, though it does run warm during use and won't fully refill a large-battery phone in one go.

Design

0.34-inch thick card-style body with curved edges and a metal frame; available in six colorways.

Charging

15W Qi2-certified wireless charging for MagSafe-compatible iPhones; 20W USB-C input for fast recharging in under two hours.
