Charger Description

The eFest slim K2 charger is a compact, portable, and professional looking two-channel charger that has several useful features. The intelligent design will protect you from overcharging, reverse polarity, and independent charging. It automatically detects the level of your charge and will cut off when your batteries have reached their full charge.

Unlike many of the other Efests, it does not have an LED display but does show color to indicate charging is complete. This is perfect for plugging into your computer at work or into your home computer to give it the charge it needs.
