How do I charge my WHOOP Battery Pack 4.0?

Plug your battery pack 4.0 into a power source using your WHOOP-provided USB-C cord. While charging, the LED will stay red. Once your battery pack is fully charged, the LED will turn green.

I just received my WHOOP Battery Pack 4.0, but when I clicked on my WHOOP it wasn't charging.

Make sure you charge your WHOOP Battery Pack 4.0 before trying to charge your WHOOP. See above FAQ on how to charge your WHOOP Battery Pack 4.0.
