XTAR Over 4 Slim Li-Ion Charger

The fastest cylindrical cell charger ever! The Over 4 Slim from XTAR can charge at up to 4.1A per channel - meaning you can fully charge two 2000mAh cells in just 30 minutes. You don't have to worry about charging your cells too fast, either - the charger automatically determines the appropriate charge rate every time based on the measured internal resistance of each cell.

Built-in temperature sensors constantly monitor each cell, and the charger will lower the charge rate if the cell begins to overheat. The Over 4 Slim will also charge your USB devices, with two high-power 2.4A USB charge ports built in to the side of the charger.
