Anker started by selling a better phone charger on Amazon. Fourteen years later it is putting battery walls, robot vacuums, and solar systems in homes across 100-plus countries - and betting its next act is energy, not accessories.

The Anker Nano Power Bank (5K, MagGo, Slim) - Model A1665 - is Anker's thinnest-ever 5,000mAh portable charger, measuring just 0.34 inches (8.6mm) thick. With Qi2-certified 15W MagSafe wireless charging, 20W USB-C wired charging, graphene-based thermal management, and a body made from 75% recycled materials, it redefines what a pocket-sized power bank can be. Beloved by travelers, iPhone users, and minimalists who refuse to carry a brick.
