## Long description

The Nitecore UM4 battery charger is a compact household charger designed to handle multiple common battery chemistries, including Lithium Iron Phosphate (LiFePO4), Lithium‑Ion (Li‑ion) and Nickel‑Cadmium (Ni‑Cd). It accepts a DC input of 9V and provides an output voltage of 4.35V per charging channel, and supports simultaneous charging of up to four batteries. Compatible battery sizes include AA, AAA, AAAA, C and D. The unit's black finish and slim profile are suited to everyday home use and storage.
Advantages
The UM4 provides multi-chemistry support, allowing the same charger to service LiFePO4, Li‑ion and Ni‑Cd cells. With four charging slots it enables parallel charging of several batteries, reducing waiting time. The charger’s DC input and standardized 4.35V output simplify integration with common DC power sources. Compact dimensions and a discreet black colour make it convenient to place on a shelf or in a drawer without occupying much space.
