Nitecore UMS4

We are pleased to introduce you to the intelligent dual-slot charger NITECORE UMS4 USB, which has been designed with emphasis on speed, safety, and efficiency in battery charging. The UMS4 charger achieves a maximum total output of 4000 mA when used with a 2A USB adapter. If the charger is powered or connected to a quick charging adapter (QC), one of the slots will reach a maximum output of 3000 mA, and the screen will display "Quick Charge".

The charger is equipped with a backlit LCD display, which provides real-time information about the charging status, including battery status, charging time, number of charged batteries, charging current, voltage, battery type, cut-off voltage, and charging mode. The UMS4 model also has an energy-saving function, which turns off the LCD display after 10 minutes of inactivity with buttons or batteries.

This intelligent USB charger can automatically identify the correct charging current and voltage for a given battery and allows users to manually set the charging current and voltage for specific battery types. The UMS4 supports various types of batteries, including li-ion, imr, lifep04, ni-cd, and ni-mh, as well as different battery sizes such as 18650, 16340, and 14500.
