The UMS2 is a 3A, 2 slot USB quick charger capable of a maximum output of 4000mA.  Specifically optimized to charge IMR batteries in various sizes (yet perfectly compatible with Li-ion, LiFePO4, NI-MH & Ni-Cd in various sizes (see specs to ensure compatibility)), the programming of the unit effectively extends the lifespan of your cells by ensuring the charge process finishes with the cell voltage within safe limits.   

 

The UMS2 features automatic detection of cell power levels which then automatically sets the appropriate voltage and charging mode (LiFePO4 and 3.8V Li-ion batteries excluded). The charge settings can also be manually adjusted to suit various charging needs.  The UMS4 is energy-efficient and boasts a large and detailed LCD that provides real-time charging information as well battery internal resistance and the health of the cell. 

 

The UMS2 comes standard with piece of mind also: insured worldwide by Ping An Insurance (Group) Company of China, Ltd., made from durable and fire-retardant PC materials designed for optimal heat dissipation, and fitted with a plethora of safety features like reverse polarity protection, short circuit protection, over-discharged battery activation, and overtime charging protection. 

RoHS, CE, FCC, and CEC certified.
