UMS4 Charger

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."

Great charger

Great charger and it helps me to repair my other brand Li ion battery 🔋 that is Over Discharged and Over Discharged IMR battery Restoration 🔋

UMS4 Charger does the work!

Great practical product, I start using rechargeable batteries for night light, bicycle lights etc or simply use on products around the house. The charging by the Charger is fast and the LED indication is clear to see.

Great Charger

Bought this to replace my current Nitecore Intellicharger i4 years back, although some slot of the spring become very still but still can use to charge those 18650 batteries. And this new USM4 is a good improvement to charge all types of batteries fast with OLED display that tells you how much volt and current is using and even can revive dead battery. Best part is it will indicate fast charge or normal depend on your power source. Highly recommended!

Cheong Kevin

Received it quite fast thats an A+ for me .
Tested it out on the QC3 Anker USB charger really love the displayed info on all the different batteries .
Don't regret buying the UMS4 at all. 😻

UMS4 Battery Charger

Clear display on battery status. Allows for configuration if charging different types of batteries. Would recommend since all flashlights run better on respective suggested rechargeable batteries to optimize performance.
