Nitecore UM2 Intelligent USB Charger – Multi – Li-ion, LiFePO4, Ni-MH, Ni-Cd Charger
THE WORLDS BEST MULTI – CHARGER, HAS JUST GOTTEN BETTER!
The Nitecore UM2 is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers.
The UM2 automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging LiFePO4 batteries.
Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the UM2’s two microcomputer-controlled charging slots then monitors and charges the battery independently.
Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current and time while an intelligent automatic power-off function terminates current when charging is complete.
The new NITECORE UM2 is a QC input available, Intelligent USB dual-slot charger, with a total max output of 3,000 mA and a single slot max output of 1,500 mA and is capable of charging 2 batteries simultaneously and controlling each slot independently.
It only takes 2 hours to charge 80% of a 3,500mAh battery.
The LCD screen can display a real-time information of Charging Current, Battery Voltage, Charged Volume and Charging time.
It can enable an automatic detection of battery power level and automatic selection of the appropriate voltage and charging mode and automatic selection between 3 charging modes (CC, CV and -dV/dt).
The charging parameters can be set manually as well to meet various charging needs.
The specially designed Micro USB port is compatible with various Mobile Power Source, Solar Panel, Powerbanks and USB Adaptors to ensure endless power supply.
UM2 incorporates an optimized IMR battery charging program, which is able to monitor the entire charging process, ensuring that the cut-off voltage is always within safe limits to extend the lifespan of the batteries.
The UM2 is compatible with 3.6V/3.7V Li-ion rechargeable batteries, 3.8V Li-ion rechargeable batteries, 1.2V Ni-MH/Ni-Cd rechargeable batteries and 3.2V LiFePO4 batteries.
Multiple safeguards ensure the safe charging process, including anti-short circuiting and reverse polarity protection, overtime charging protection, over-discharged Li-ion battery activation and over-discharged IMR battery restoration.
Apart from being constructed from durable and fire retardant PC materials, the built-in temperature regulation system is designed to prevent the overheat and to ensure the stability of the charging process.
If there is no action to the buttons or batteries in 10 minutes, the screen will automatically go dim to save energy.
