NITECORE. UM4 CHARGER

A four-position smart charger with quick charge (QC) capability,
a total maximum charging current of 3000mA (QC) and a single position maximum charging current that can reach 1500mA
Liquid crystal digital display (LCD) for real-time information presentation of charging.
Charging from a USB port makes it an ideal charger for outdoor activities.
It has an improved charging program for IMR battery.
Detects internal resistance and battery health.
It automatically selects between three programs (CC, CV and -dV / dt) according to the type and capacity of the batteries.
Charging parameters can be manually adjusted to meet different needs.
It is compatible with various external energy sources such as USB adapters, Power Banks, Solar Panels etc.
It has the ability to restore over-discharged IMR batteries.
It has the ability to activate over-discharged Li-ion batteries. It will check and activate before it starts charging. If the battery is damaged the display will show the message “EE EE”.
It has reverse polarity and short circuit protection.
If there is no action on the charger buttons within 10 minutes, the display will turn off to save power.
It is made of durable polycarbonate materials, fire retardant.
It incorporates a smart temperature regulation system designed to protect it from overheating.
The unique cooling fins are designed for excellent cooling performance
