NOT HEATING? FIX IT FAST.

If your vest isn’t heating up properly, don’t stress.

1
Check your charge
Press the button on the side of your battery. If fewer than 4 dots light up, give it a full charge.
2
Test the cord
If the battery isn’t charging at all, try a different USB-C cord, outlet, or power block to rule out the cable.
3
Confirm your connection
Make sure the battery is plugged securely into the cord inside the left pocket — same side as the power button.
4
Double power-on
Press and hold the power button for 3 seconds — you may need to do this twice the first time to connect.
5
Flickering light?
Rapid flashing means low battery. Fully charge again before use.
6
Pro tip
Always unplug the battery while not in use to preserve charge life.
