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?

Battery Type (Capacity)	One at a time 1500mA	Two at a time 750mA	Four at a time 375mA
18650 (3500mAh)	2hr 20min	4hr 36min	9hr 20min
18650 (2600mAh)	1hr 44min	3hr 28min	6hr 56min
RCR123 (650mAh)	1hr 18min		1hr 44min
Eneloop AA (2000mAh)	1hr 20min	2hr 40min	5hr 20min
Eneloop AAA (800mAh)	1hr 36min		2hr 8min

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."
