Superfast 3000mA. The Fastest 2 Slot Intelligent USB Charger On The Market Today.

3 reasons why this should be your next charger

Quick and Efficient Charging
Designed to charge your batteries fast, safe and efficiently. Works best when using a 2A output USB power adapter. When connected to quick charge (QC) power adapter, the screen will show “Quick Charge” and a single slot will achieve a max output of 3000mA.

LCD Display with Real-time Charging Information
A brightly lit LCD displays battery health, charging time, charged volume, charging current, battery voltage and type, cut-off voltage and charging mode. An energy saving function activates and dims the LCD display after 10 minutes, when there is no action to the buttons or batteries.

Intelligent USB Charging
Intelligent charging technology automatically detects and applies the appropriate charging current/voltage while allowing users to manually adjust the charging current/voltage for specialized battery types.

Great product, the Battery management system display is very informative

Alex Loi
UMS2 charger

A charger which is compact and able to charge various types of batteries.👍🏻

Works far better than regular off-the-rack chargers

The chargers that come with off-the-rack NiMH batts don’t do a good job at all. Even after charging for the recommended time, batts still die very quickly or don’t work at all. This Nitecore UMS2 charger does a great job every time and I know my batts are fully charged!

Izzati Rasul
