UMS4 Charger (4 Slots)

Superfast 3000mA. The Fastest 4 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.

"I use this charger with a the same PD 3.0 USB wall plug i use to charge my laptop, and it charges just as well as QC 2.0/3.0. Two batteries pull 2A without a problem for super fast charging.

The display is easy to read, the controls are easy to navigate, and it provides more information that a lot of other chargers in the market.

Also, the charger does not make the high pitched electric whining noises that I am so sensitive to - an indicator of high quality.

All in all, this charger meets the high standards I expect in my devices. Will buy Nitecore again."
