Introducing the Nitecore UMS4 Intelligent USB Four-Slot Superb Battery Charger, designed to recharge your batteries fast, safe and efficiently. The UMS4 will reach a maximum total output of 4A when using a ≥2A output USB power adapter. When the charger is powered or connected to quick charge (QC) power adapter, the screen will show “Quick Charge” and the single slot will achieve a max output of 3A.
LCD DISPLAY WITH REAL-TIME CHARGING INFORMATION - A brightly lit LCD display reports real information including battery health, charging time, charged volume, charging current, battery voltage and type, cut-off voltage and charging mode. The UMS4 offers an energy saving function that activates and dims the LCD display in 10 minutes, when there is no action to the buttons or batteries.
INTELLIGENT USB CHARGING - The UMS4’s intelligent charging technology automatically detects and applies the appropriate charging current/voltage while allows users to manually adjust the charging current/voltage for specialized battery types. The UMS4 supports various battery types (Li-Ion / IMR / LiFeP04 / Ni-Cd / Ni-Mh) and common battery sizes including (18650, 20700, 21700).

IMPORTANT NOTE: Understanding how to handle and care for Lithium-ion batteries is very important and should always be practiced. Lithium type batteries are very sensitive to charging characteristics and may explode or flame if mishandled. DO NOT charge your batteries overnight or while unattended for a prolonged period of time! Always charge your batteries in a fire-proof surface/area and DO NOT expose them to high temperatures (e.g. inside your car). DO NOT expose the battery's terminals to metal objects or immerse in water/liquid. We are not responsible for any damage if there is any misuse, abuse or modification of the batteries and/or chargers in any shape or form (including operating while wired in series). Furthermore, Electric Vapor Cigarettes LLC (a.k.a. EVcigarettes.com) will not be held responsible or liable for any injury, property damage, or defect that is caused by misuse, abuse or modification of Lithium batteries and/or chargers.
