Charging dock for 4 batteries
The Nitecore UM4 is an intelligent USB charger that sets new standards in battery charging with its advanced technology and four charging slots. With QC 2.0 compatibility and a sophisticated LCD display, the UM4 enables fast and gentle charging of your batteries.
The charger supports the following battery types: Li-Ion, Li-Ion IMR, NiMH/NiCd, and LiFePO4. Its intelligent detection system determines the battery type and condition, analyzes the charge status, and automatically selects the appropriate charging method. No matter which battery you want to charge, the UM4 always ensures optimal charging.
The standard charging current of the UM4 is 500 mA. For flexible adaptation to different battery types, the charging current can be manually increased to up to 1 A and even up to 1.5 A when using QC mode. This ensures that every battery is charged quickly and safely.
Another remarkable feature of the charging dock is its ability to reactivate deeply discharged Li-Ion batteries. This process allows you to extend the lifespan of your batteries and ensures that you can always rely on the full performance of your devices.
