The Nitecore D4 is a universal smart charger compatible with almost all cylindrical rechargeable batteries. With LCD to display the status of power charging, the Smart Charger NiteCore D4 also comes with four battery slots, so it can charge four batteries at one time. The Nitecore D4 automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging LiFePO4 batteries. Besides, it also provides reliable and overall protection for your batteries.
I've been using the D2 for the last couple of weeks, great little unit
