Quick and Efficient Charging
Introducing the NITECORE UMS4 Intelligent USB dual-slot charger designed to recharge your batteries fast, safe and efficiently. The UMS4 will reach a maximum total output of 4000mA when using a 2A output USB power adapter. When the charger is powered or connected to quick charge (QC) power adapter, the screen will show “Quick Charge” and the single slot will achieve a max output of 3000mA.
LCD Display with Real-time Charging Information
A brightly lit LCD display reports real information including battery health, charging time, charged volume, charging current, battery voltage and type, cut-off voltage and charging mode. The UMS4 offers an energy saving function that activates and dims the LCD display in 10 minutes, when there is no action to the buttons or batteries.
Intelligent USB Charging
The UMS4’s intelligent charging technology automatically detects and applies the appropriate charging current/voltage while allows users to manually adjust the charging current/voltage for specialized battery types. The UMS4 supports various battery types (li-ion/imr/lifep04/ni-cd/ni-mh) and common battery sizes including (18650, 16340,14500).
