The Nitecore D4 EU is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers.

The D4 EU automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging LiFePO4 batteries.

Compatible with and identifies Li-ion / IMR / LiFeP04: 26650, 22650, 20700 (unprotected cell), 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440 Ni-MH and Ni-Cd: AA, AAA, AAAA, C rechargeable batteries.

Optimised charging design for IMR batteries.

Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the D4’s four microcomputer-controlled charging slots then monitors and charges the battery independently.

Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current and time while an intelligent automatic power-off function terminates current when charging is complete.

The Nitecore D4 EU : The world’s most advanced fully-automatic digital charger. It’s as simple as insert, detect and charge.
