Nitecore UMS4 Charger

An extremely intelligent four-slot charger with quick charge (QC) capability, total maximum charge current of 4000mA (QC) and maximum charge current in a single slot that can reach 3000mA (QC, can charge a 18650/3500 battery in 55 minutes). Digital liquid crystal display (LCD) for real-time display of charging information. Charging from a USB port, making it an ideal charger for outdoor activities. It has an improved charging program for IMR batteries. It detects the internal resistance and health of the battery. The UMS4 automatically selects between three programs (CC, CV and -dV / dt) according to the type and capacity of the batteries. The charging parameters can be manually adjusted to meet different needs. It is compatible with various external power sources such as USB adapters, Power Banks, Solar Panels, etc. It has the ability to restore over-discharged IMR batteries. The UMS4 has the ability to activate over-discharged Li-ion batteries. The UMS4 will check and activate before starting charging. If the battery is damaged, the message “EE EE” will appear on the screen. It has reverse polarity and short circuit protection. If there is no action on the charger buttons within 10 minutes, the screen will turn off to save energy. It is made of durable, fire-retardant polycarbonate materials. It incorporates an intelligent temperature control system that is designed to protect it from overheating. The unique cooling fins are designed for excellent cooling performance.
