Nitecore UI1 battery charger

The Nitecore UI1 battery charger is an intelligent charger. As soon as you place the battery in the charger, the U1 will automatically adjust to fit the type of battery. As such you make optimal use of the battery life. The charger works via a USB connection and weighs next to nothing. With it you can easily charge your battery.

Intelligence of the Nitecore UI1

The Nitecore UI1 has a charging capacity of 800mA or 100mA. When you charge a battery with a voltage below 2.9V, the charger will automatically activate the ‘Low Current Charging’ mode. When you charge a battery with a voltage higher than 2.9V, the charger will use the standard mode of 800mA. As such the life of the battery is optimally used.

But that is not all! The Nitecore UI1 has many more functions. If the battery is inserted upside down, the three indicators will turn red and the charger will not charge the battery. Also if the charger becomes too hot the UI1 will change the charging capacity. This protects both the charger and the battery, As soon as the battery is fully charged the charger will automatically stop charging. Great!

Practical functions on the Nitecore UI1

The charging indicators always show you the current charging status. As such you can quickly see how full the battery is. With the Nitecore UI1 you can also reactivate deeply discharged Li-Ion batteries. As soon as you put the battery in the charger, the UI1 will check the battery status. After this check the charger will start charging the battery. As such the battery will receive the right treatment.

Because of the USB connection you can easily charge the battery with a micro-usb cable. Because of this connection you have a lot of charging options. Think of charging via an adapter, but also via a powerbank, solar panel or with the Nitecore F2 Flexible Power Bank,
