1.  CHARGING THE INTERNAL LITHIUM  

ION BATTERY 

Your ThermoCharge 3 2-in-1 device has an internal, 3000 mAh 
rechargeable lithium ion battery, which allows for at least 4 hours 
of continuous use at a constant temperature of 104° to 113° 
Fahrenheit (40° to 45° Celsius). Your ThermoCharge 3 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 3.

2.   Plug the standard USB plug end of the cable into a USB port
    on a PC, laptop, car charger or USB 5V-1A adapter plug.

3.  Once plugged in, the blue LED (4) will start to blink, 

indicating that charging is in progress.  

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

NOTE:  

The ThermoCharge 3 is designed with overcharge 
protection to prevent damage to the internal battery.

2. USING THE HAND WARMER FEATURE

•  Press and release the on/off button once (3). The unit will 

begin to heat up. In minutes, it will reach its maximum 
temperature and you will feel the heat being conducted 
through the aluminum housing.  

•  Press the on/off button again to turn the ThermoCharge 3 off.

3. CHARGING AN EXTERNAL DEVICE

•  Plug your device’s USB charging cable into the USB 2.0 port (5) 

on the ThermoCharge 3.

•  Press and release the on/off button (3) quickly, then press and 

hold the on/off button to begin charging. Your device should 
indicate it is charging.
