Nitecore UM10 Single Battery Charger

Sold out
The Nitecore UM10 Battery Charger is an advanced USB battery management and charging system that is capable of powering lithium ion batteries from a wall outlet while simultaneously charging an external electronic device such as a mobile phone or tablet. The UM10 also works as a data transfer medium when a device is plugged in.

Compared to most battery chargers, the Nitecore UM10 charger is highly portable due to its compact size. The single-bay Nitecore UM10 has two charging ports – one on top and another at the back. This way you can charge one Li-ion battery and an external device simultaneously.

During low power conditions, you have the option to prioritize charging according to your preference.

Unlike most chargers, the UM10 has an LCD screen in front that displays charging progress and battery power levels in real time.

At the back of the Nitecore UM10 is a cable winder that eliminates cable clutter while the rear USB port allows you to transfer data to your device while it is charging. Safety is always an issue with battery chargers, and Nitecore has gone the extra mile to ensure that your batteries and devices are protected while charging.

The Nitecore UM10 is made of high-quality, fire-retardant ABS plastic. It has reverse polarity protection and automatically selects charging current based on battery capacity. The UM10 also has the capability to detect input power and distribute charging power effectively.

Priority Mode -
-When used with a high power adapter, the UM10 can charge both the battery and external device simultaneously. When used with a low power adapter, the UM10 has a priority switch that allows the user to select which to charge first.
-When input power is sufficient, the UM10 will charge the battery and device simultaneously.
-When input power is not sufficient to charge both battery and device, the UM10 will go into Priority Mode and start the charging process based on user preference.
-When input power is not sufficient and Priority Mode is set to Battery, the UM10 will charge the battery first. Once the battery is fully charged or removed, the UM10 will start charging the external device automatically.
-When input power is not sufficient and Priority Mode is set to Device, the UM10 will charge the external device first. Once the device is fully charged or disconnected, the UM10 will start charging the battery automatically.

Data Transfer -
The Nitecore UM10 also serves as a data transfer medium via USB. While your device is charging on the UM10, you can connect your Nitecore charger to a computer and start transferring data.

Clutter-Free Charging -
No more tangled mess. The cable winder at the back keeps all excess wire tucked in a clean loop with grooves that can accommodate 2.5mm and 3.0mm thick cables.

Guaranteed Safety -
Constructed from fire-retardant materials, the Nitecore UM10 is designed for optimal heat dissipation. It also has reverse polarity protection that automatically stops the charging process if the battery is installed backwards.

Authenticity Code -
All genuine Nitecore chargers carry a product ID sticker, a scratch code, and a QR code on the packaging. Validation codes and QR codes can be verified through the Nitecore website.

How To Use Your Nitecore UM10 Charger:
-The base of the UM10 charger flips open to reveal the USB port underneath the charger. The included power cord is a micro USB cable that can be connected to a micro USB capable external device or into the micro USB input port on top of the UM10.
-When the UM10 is connected to a power supply, the LCD screen will light up and display 0% with an empty charge bracket.
-When a battery is installed in the charging bay, the LCD screen will indicate the battery's current charge level in percentage. The bracket on the left side will also display a number of charge indicator bars which correspond to the current battery charge percentage.
-When charging is complete, the Nitecore UM10 LCD screen will show 100% plus 5 charge indicators bars.
-When you insert a battery, the UM10 will automatically detect battery type and choose the appropriate charging current. Large capacity batteries will charge at a rate of 1000mA while smaller batteries will charge at 500mA.
-Nitecore does not recommend charging zero volt overdischarged unprotected Li-on batteries. If the UM10 detects a damaged battery, the error code ""EE"" will show up on the LCD screen.
