NITECORE D4 Battery Charger (4-Bay)

The Nitecore D4 4-Slot Battery Charger with LCD Display is a powerful and versatile charging solution designed for both beginners and advanced users. Featuring four independent charging bays, the D4 allows you to safely and efficiently charge multiple batteries at the same time, even if they’re different sizes or chemistries.

Compatible with Li-ion, IMR, LiFePO4, Ni-MH, and Ni-Cd rechargeable batteries, the D4 automatically detects the battery type and status before applying the optimal charging mode (CC, CV, or dV/dt). This intelligent design ensures each battery gets the safest, most efficient charge possible.

The large LCD display provides real-time information on voltage, current, and charging progress, making it easy to monitor each slot independently. Safety is a top priority with built-in temperature monitoring, overcharge prevention, reverse polarity protection, and a fire-retardant ABS housing. The D4 also features excellent heat dissipation, ensuring long-lasting performance.

Certified by RoHS, CE, FCC, and CEC, the Nitecore D4 offers unmatched reliability, making it a must-have for vapers, gadget users, and anyone who relies on rechargeable batteries.
