Not ideal...
Review by

I bought 3 of these. Charging is less than optimal even after 18 hours and green lights on all of them. They do operate as normal but dissipate unusually quick.

Will not work with USB-C chargers

The USB-C port on this battery is not implemented properly, and so most USB-C chargers will not charge it. If you want to charge the battery via USB-C you'll need to use a regular USB-A power source and a USB-A to USB-C cable. Other than that this is a perfectly fine battery.
If you want to learn more about how USB-C is supposed to work you can google "USB-C pulldown." Basically the issue here is that there is no pulldown resistor on the battery's USB-C port to let the charger know what kind of device this is and whether to feed it 5V or something else, so most chargers won't send voltage. USB-A doesn't support anything like this and will just blindly feed 5V over an adapter cable.

using usb to charge battery

Charging for over 18 hours via USB and still not fully charged, it is at 7.75 volts though which would power the radio for a while. Same charger/cable pair charges my cell in 3 hours.
