The Anker Nano is a 5,000mAh Qi2-certified magnetic power bank that snaps onto the back of an iPhone and charges wirelessly at up to 15W. It is about 0.3 inches thin and weighs 0.23 lb, so it rides in a pocket without bulk. A USB-C port adds up to 20W wired output for other devices. At $54.99 at Walmart as of November 7, 2026, it sits at the top of its recent range: 6 stores carry it new and this is the best current price, so it is not a discount moment.
