1.  CHARGING THE INTERNAL LITHIUM  

ION BATTERY 

Your ThermoCharge 2-in-1 device 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° to 45° Cel-
sius (104° to 113° Fahrenheit).  Your ThermoCharge ships with a 
partial charge, but you should charge it completely before using 
it for the first time.  

Follow these steps to charge the internal battery:   
 1.  Attach the Mini USB connector end of the included USB cable 

to the Mini USB “in” port (1) on your ThermoCharge.

2.  Plug the standard USB plug end of the cable into a USB port 

on a PC, laptop, car charger or USB 5V-500mA adapter plug.

3.  Once plugged in, the blue LED (2c) will start to blink, indicat-

ing that charging is in progress.

4. Charging is complete when the blue LED (2c) stops blinking.  

NOTE:  

The ThermoCharge is designed with overcharge protec-
tion to prevent damage to the internal battery

housing.  

• Press the on/off button again to turn ThermoCharge off.
•  Use the included caps when extra protection is needed.  These 

silicone caps help repel moisture and protect the device should 
it be dropped on a hard surface.

(4) on ThermoCharge.
