Nitecore Intellicharger i4:

The Nitecore Intellicharger i4 is a universal, automatic smart-charger compatible with almost all types of rechargeable batteries thus eliminating the need to own several chargers. The i4 is able to automatically identify Li-ion, Ni-MH and Ni-Cd rechargeable batteries and apply an appropriate charging mode (Constant Charge Current (CC), Constant Charge Voltage (CV) and Trickle Charge). Additionally, yellow and blue power/charging status indicator lights could visibly indicate battery status and charging process. Features: Capable of charging 4 batteries simultaneously Each of the four battery slots monitors and charges independently Automatically identifies Li-ion, Ni-MH and Ni-Cd rechargeable batteries Features three charging modes (CC, CV and Trickle Charge) Automatically detects battery status and selects the appropriate voltage and charge mode 3 Color LED displays charging progress for each battery Automatically stops charging when complete. Features reverse polarity protection Designed for optimal heat dissipation Certified by both RoHS and CE Input voltage: AC 100-240V 50/60HZ or DC 12V Dimensions: 139mm × 96mm × 36mm Weight: 156g (without batteries and power cord) Compatible with: Li-ion: 26650, 22650, 18650, 17670, 18490, 17500, 17335, 16340(RCR123), 14500, 10440 Ni-MH/Ni-Cd: AA, AAA, C. DC Adapter Not Included Batteries Not Included

Nitecore Intellicharger i2:

The Nitecore Intellicharge i2 is a universal, automatic smart-charger compatible with almost all types of rechargeable batteries thus eliminating the need to own several chargers. The i2 is able to automatically identify Li-ion, Ni-MH and Ni-Cd rechargeable batteries and apply an appropriate charging mode (Constant Charge Current (CC), Constant Charge Voltage (CV) and Trickle Charge). Each of the i2's two microcomputer-controlled charging slots is capable of monitoring and charging batteries independently. Additionally, yellow and blue power/charging status indicator lights could visibly indicate battery status and charging process. i2: The all-new highly advanced smart charger. It's as simple as insert, detect, and charge.
