Nitecore UMS4 Intelligent 4-Slot Battery Charger

Introducing the Nitecore UMS4 - An Intelligent Four-Slot Charger with Unmatched Efficiency and Safety

Max Output and Charging Speed Capable of a total max output of 4,000 mA and a single slot max output of 3,000 mA, the UMS4 charges four batteries simultaneously. It takes only 55 minutes to charge 80% of a 3,500 mAh battery, making it one of the fastest chargers in its class.

Real-Time Battery Health Monitoring The UMS4 features an intuitive LCD screen that displays real-time information. It indicates battery health as “Good” or “Poor,” shows internal resistance, charging current, battery voltage, charged volume, and charging time.

Automatic Battery Detection and Intelligent Charging The charger automatically detects battery power levels and selects the appropriate voltage and charging mode. It offers three charging modes: Constant Current (CC), Constant Voltage (CV), and -dV/dt. Manual charging parameters can be set to meet various needs.

Optimized IMR Charging Program Equipped with an optimized IMR battery charging program, the UMS4 ensures the cut-off voltage remains within safe limits, extending the lifespan of your batteries. It is compatible with 3.6V/3.7V Li-ion, 3.8V Li-ion, 1.2V Ni-MH/Ni-Cd, and 3.2V LiFePO4 batteries.

Built-in Safety Features Multiple safeguards ensure safe charging. Automatic internal resistance detection, anti-short-circuiting, and reverse polarity protection are included. Over-time charging protection, over-discharged battery activation, and over-discharged IMR battery restoration further enhance safety.

Durable and Safe Construction Constructed from durable and fire-retardant PC materials, the UMS4 is built to withstand rigorous use. A built-in temperature regulation system prevents overheating and ensures a stable charging process.

Versatile Power Compatibility The specially designed USB-C port allows compatibility with various mobile power sources, solar panels, and USB adaptors, ensuring a continuous power supply.

Proudly designed to meet your charging needs with speed, efficiency, and unmatched safety, the Nitecore UMS4 is your ultimate choice for charging Li-ion, LiPo, Ni-MH, and Ni-Cd batteries.
