Introducing the eFest MEGA USB Charger: The Efest MEGA Li-Ion and Ni-MH battery charger is a cost-effective and smart USB battery charger, capable of charging a wide variety of different batteries.

LED Indicator
“Li-Ion” and “Ni-MH” indicators will both light up when charging their respective battery types. A built-in 4 power level indicator will indicate charging percentage.
Automatic Battery Recognition
Recognising battery length to set the best charging rate automatically, the Efect MEGA protects smaller batteries from stress and excess heat to extend the life cycle. Faster charging will be set automatically for bigger batteries. 1A fast charge will be automatically selected on batteries with a cell length of greater than 63mm, while 0.5A will be selected for batteries with a cell length of less than 63mm. Charge both Li-Ion and Ni-MH batteries simultaneously.
