CHARGING THE INTERNAL LITHIUM ION BATTERY
Your ThermoTank hand warmer has an internal, 4400 mAh
rechargeable Lithium Ion battery, which allows for up to 6
hours of continuous use at a constant temperature of 40°

partial charge, but you should charge it completely before
using it for the first time.
TO CHARGE THE BATTERY:
1. Plug the Mini USB connector into the Mini USB port
(1) on the ThermoTank.
2. Plug the standard USB plug end of the included USB
cable into a USB port on a PC, laptop, car charger or USB
5V-500mA adapter plug
3. Once plugged in, charging will begin and the Red LED
(3) will start to blink.
4. When the Red LED (3) stops blinking, the charge
is complete.
NOTE:
The ThermoTank is designed with overcharge
protection to prevent damage to the internal battery.
