Nitecore UMS2 Universal Intelligent Charger - 2 Slots - 3000mA Max USB

The Nitecore UMS2 Intelligent Charger is a portable 2-slot charger for Li-ion/IMR/LiFePO4 batteries and Ni-MH/Ni-Cd cells with maximum output of 3000mA. Equipped with a USB port with QC 2.0 support, it enables fast charging and can be powered by external battery or solar panel. Compatible with 21700 format. Revolutionary technology to charge IMR batteries, restore over-discharged Li-ion batteries and manual selection of charging parameters. The 2 slots are independently controlled with automatic detection of battery type. More powerful than UM2 with 3000mA in fast mode versus 1500mA.

USB Port and QC 2.0 Fast Charging Mode

The UMS2 integrates a USB port with QC 2.0 support allowing connection via external battery or solar panel for portable charging. Fast charging mode automatically activates with QC source: the screen displays "Fast Charge" and the charger reaches 3000mA in single slot or 2000mA per slot (2 batteries). Standard mode: 2000mA (1 battery) or 1000mA per slot (2 batteries). The LCD screen displays real-time information: mode, voltage, battery type, charging time, power and charged volume. Energy saving function: screen automatically dims after 10 minutes of inactivity.

Intelligent Charging and Maximum Safety

The UMS2 automatically detects battery type, capacity and internal resistance (displays "Good" or "Poor"). Automatic selection between 3 charging modes (CC, CV, -dV/dt) with manual adjustment option for voltage and current. Capable of activating over-discharged Li-ion batteries and restoring discharged IMR batteries (hold V button). Complete protection: anti-reverse polarity, anti-short circuit (displays "EE EE") and automatic stop after 20h. Made from fire-resistant PC with optimal heat dissipation. RoHS, CE, FCC, CEC certifications.
