Aliexpress. A simple TP4056 usb-c charging board costs as little as 50p. For a few pence more you can get a power bank board with a charge controller and a 5v boost converter.

Interesting, I have some TP4056 already, but wouldn't I need some form of "balance" circuitry if I want to connect multiple of these together, to ensure they're all charged and discharged evenly?
