Nitecore D4

Nitecore D4 is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The D4 automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging LiFePO4 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: The world's most advanced fully-automatic digital charger. It's as simple as insert, detect and charge.

Nitecore NEW i2

Nitecore NEW i2 Intelligent Charger - upgraded edition of the i2, is a charger with compatibility, efficiency and intelligence

The NEW i2 is extremely efficient as it is able to charge batteries twice as fast as the i2 (up to 1A), which will drastically reduce charging time. With the Active Current Distribution (ACD) Technology, the NEW i2 automatically identifies battery types and capacity, and then applies an appropriate charging current based on automatic detection or manual setting. The design of non-rechargeable batteries automatic detection takes safety issues out of concern and ensures top safety during use. It can even restore your depleted IMR batteries. It works with almost all types of rechargeable batteries, thus eliminating the need to own several chargers. Additionally, yellow and red indicator lights could visibly indicate battery status and charging process at real time. NEW i2, it's as simple as insert, detect and charge.
