The big brother of Nitecore UM2 with a little more charging current in the reserve for switching on.
The Nitecore UMS2 is visually indistinguishable from the UM2. However, the letter "S" reveals the slightly better equipment.  The Nitecore UMS2 has besides higher charging current of max. 3A on one slot or together 4A on two slots, battery status detection and indication after inserting the battery by "GOOD" or "POOR". 
 

The Nitecore UMS2 works with up to 3A on one slot.

 

Equipped with Quick Charge 2.0 processor, charging the batteries with a USB QC power adapter becomes unusually fast. Nitecore used the process that was originally developed for smartphones to optimise the power supply of the chargers. Besides the 2 bay Nitecore UM2 charger, the Nitecore UMS2 presented here was also equipped with QC interface.
 

 

Intelligent Universal Charger Nitecore UMS2 for Li-Ion, LiFePO4 and NiMh Batteries


The Nitecore UMS2 charger detects the battery type, determined battery condition, battery charge level and automatically determines the correct charging method. Charging of batteries up to a length of 77mm e.g. protected 20700/21700 batteries, automatic battery internal resistance detection, calculation of the charged capacity as well as Li-Ion battery reactivation are further useful additions.

Enables charging of Li-Ion, Ni-MH, Ni-Cd and LiFePO4 batteries. The charging system is optimised for IMR batteries and charges the batteries safely and gently. The LCD display shows the charging current, charging voltage, resistance and charging time for each charging slot. CE, FCC, ROHS and CEC certified.

The following battery types can be charged with the Nitecore UMS2 :

Li-Ion/LiFePO4:10440, 14500, 14650, 16500, 16340(RCR123), 16650, 17350, 17500, 17650, 17670, 17700, 18350, 18490,
