Trust the Milwaukee® M18™ Sequential Charger to keep your tools powered even through the toughest uses. This device provides the power, and it works with REDLITHIUM® technology to charge M18 batteries with ease. Just plug the batteries into this six-port charger, and it takes care of the rest, powering the full set in sequence, one battery at a time. It boasts a pass through plug to free up power socket usage, and it keeps the area free of extraneous power cords. Use this six-pack charger to restore power to M18 batteries just a half hour. The larger batteries (XC) take about twice that time and store a higher total capacity for each use. Like most Milwaukee chargers, this one includes a well-conceived design that maximizes impact without taking up much space. Sequential charging allows one battery to charge as soon as the last battery finishes, and it helps increase efficiency during work hours. It even includes a handle for easy transport.
