MOXOM MX-PB116 WL 10000mAh Magnetic Wireless Power Bank with Built-In Cable

The cable is attached, which is the one thing none of the other magnetic banks here can say. No hunting through a bag for a lead that migrated to somebody else's desk — it is built into the body and it is there when the phone is flat.

Three ways to charge from one brick: snap it magnetically to a compatible phone for up to 15 W with no cable at all, run the built-in lead, or plug into USB-C for 20 W Power Delivery. There is an 18 W Quick Charge path as well for phones that want it. Ten thousand milliamp-hours behind all three.
