The Anker Nano Power Bank (5K, MagGo, Slim) is a 0.3-inch-thin, 5,000mAh Qi2 MagSafe-compatible battery that magnetically snaps to your iPhone for wireless top-ups on the go.

At just 0.3 inches thick, it disappears against the back of your phone while delivering 15W Max MagSafe-compatible wireless charging — enough to take an iPhone 17 Pro to 25% in about 34 minutes. A 20W Max USB-C port adds wired charging when you want it, and continuous battery protection keeps things safe.

Graphene cooling, dual NTC chips, and smart charging adjustments keep the surface below 104°F — about 14 degrees cooler than the industry standard — for safer, more reliable charging.
