G.T. Power Li-Po Battery Tester and USB Charger

This innovative product from GT Power is two devices in one - a one to six cell LiPo battery tester and a USB connected device charger. Plug any 2S to 6S LiPo battery into this handy device and you have an instant portable charger for a USB connected mobile device. Charge your cell phone, tablet, and virtually any device that has a USB compatible charging cable. To protect the life of your battery, the charger has an integrated low-volt cut-off circuit to prevent over discharge of your LiPo battery. When you are not charging your mobile devices, use this device to test the voltage of your LiPo batteries. This is a neat and useful device for topping off your mobile phone battery when you're down at the flying field - just remember to take your charging cable with you!

- Connects to the balance lead on 2-6S lithium batteries
- Test your battery's voltage and cell count 
- The USB output will be cut off automatically when the battery voltage falls below 3.0V and at the same time the LED will display 'SOP'
- Uses the popular standard-size USB “A” connector (approximately 4mm x 12mm)

Remark: This charger does not charge LiPo batteries.  It charges items like smart phones, etc.
