Nitecore UMS4 Intelligent QC 4-Slot Quick Battery Charger

The NITECORE UMS4 is an intelligent USB four-slot charger that offers a remarkable charging experience. With a total maximum output of 4,000 mA and a single-slot maximum output of 3,000 mA, the UMS4 is capable of charging four batteries simultaneously, allowing for independent control of each slot.

One of the standout features of the UMS4 is its rapid charging capabilities. It only takes 55 minutes to charge 80% of a 3,500 mAh battery, making it an efficient and time-saving option for users. The LCD screen on the UMS4 displays real-time information, including battery health (categorized as "Good" or "Poor"), internal resistance, charging current, battery voltage, charged volume, and charging time. This detailed information allows users to monitor the charging process and make informed decisions.

The UMS4 boasts advanced charging features, including automatic detection of battery power level and automatic selection of the appropriate voltage and charging mode. It also offers three charging modes (CC, CV, and -dV/dt), which can be manually set to meet various charging needs. The specially designed Micro USB port ensures compatibility with a wide range of mobile power sources, solar panels, and USB adaptors, providing users with a reliable and versatile power supply solution.

The UMS4 incorporates an optimized IMR battery charging program that closely monitors the entire charging process, ensuring that the cut-off voltage remains within safe limits to extend the lifespan of the batteries. The charger is compatible with a variety of rechargeable battery types, including 3.6V/3.7V Li-ion, 3.8V Li-ion, 1.2V Ni-MH/Ni-Cd, and 3.2V LiFePO4.

To ensure a safe charging experience, the UMS4 is equipped with multiple safeguards, including automatic battery internal resistance detection, anti-short circuiting and reverse polarity protection, overtime charging protection, over-discharged Li-ion battery activation, and over-discharged IMR battery restoration. Additionally, the built-in temperature regulation system is designed to prevent overheating and maintain the stability of the charging process. The charger's durable and fire-retardant PC materials further contribute to its overall safety and reliability.

In conclusion, the NITECORE UMS4 is an intelligent and versatile USB four-slot charger that offers a seamless charging experience. With its fast charging capabilities, precise battery monitoring, and comprehensive safety features, the UMS4 is an excellent choice for users who demand reliable and efficient battery charging solutions.
