i4 Charger (4 slots)
Ultrafast 1500mA Charger. As Simple as Insert, Detect, and Charge.
This charger works with nearly all types of rechargeable batteries. It automatically identifies Li-ion, Ni-MH and Ni-Cd rechargeable batteries to apply the right charging mode (Constant Charge Current (CC), Constant Charge Voltage (CV) and Trickle Charge).
Each microcomputer-controlled charging slot is capable of monitoring and charging batteries independently. Red, yellow and green lights clearly show battery status and charging progress.
How fast does it charge?
Charging duration uses this formula:
Battery Capacity (mAh) / Charger Output Current (mA) = Hours

"The new second edition of the i4 Intellicharger from Sysmax appears to live up to the initial promise of this model. It successfully charged all manner of cells that I threw at it, with performance generally consistent with its specifications."

"This charger uses a CC/CV charging profile, this is the recommended way to charge LiIon batteries. The charge current is a good compromise for handling many battery sizes with only one current setting. I will call it a good universal charger."
