What to look for in a power bank
Capacity: 5,000mAh is a single top-up, 10,000mAh is the sweet spot, 20,000mAh and up is for laptops, tablets or long trips.
Speed: look for USB-C Power Delivery (PD). It charges recent iPhones and Android phones much faster than old USB-A ports.
Flying: power banks must go in carry-on luggage, not checked bags. Batteries under 100Wh, which includes every power bank here, are allowed by US airlines.
Our verdict
Get the Anker for a dependable everyday charger, the INIU for the lowest price, and the Belkin magnetic pack if you have a MagSafe iPhone and want to charge without a cable.

Do magnetic power banks work with Android?
Only with phones or cases that have magnets and Qi wireless charging. Many Android users add a magnetic ring or case to use them.
