A slim magnetic power bank snaps onto the back of your phone, so you can top up on the move without a cable dangling from your pocket. All five here are 5,000mAh and thin enough to carry in a pocket.
The catch for Android owners is that these banks only hold on if your phone is in a MagSafe-compatible case or has a magnetic ring stuck on, unless it has magnets built in, as Google's Pixelsnap phones do. The five picks list from $19.99 to $69.99 on Amazon at the time of writing, ordered from cheapest to most expensive.
Baseus Picogo 5,000mAh: best budget pick
Baseus says the Picogo is 0.3 inches thin and weighs 3.8oz, with a 5,000mAh capacity and 20W USB-C. It has an aluminum shell, an NTC temperature-control chip, and comes with a 60W nylon braided USB-C cable and a 24-month warranty.
Baseus lists it as a magnetic bank for iPhones, so Android phones need a magnetic case or ring.

Verdict
The Baseus Picogo is the pick for most people, with the lowest price and a cable in the box. The FIOK is the one whose listing names Android wireless speeds, and the Anker is the best-reviewed of the bunch. The Belkin is for anyone who cares about battery lifespan, and the UGREEN is the lightest in the pocket.
Street prices on Amazon change often and can sit below these list prices, so check the current price before you buy, and keep an eye out for promotions. It will be worth seeing how the wireless speeds hold up on Android phones in everyday use.
