Using a 12-Channel Wall charger is a convenient way to make sure all your batteries are always ready for the set. Best suited for rental houses. The Kit includes screws and plates for wall-mounting. And it only uses one power cable. With three switches, you can power just four channels at once – or all twelve together. The sturdy aluminum housing and three fans on top make sure the device doesn’t overheat. The status display shows the battery voltage and charging output, so you always know the percentage of each individual battery. Easy to use – with a big impact on charging control.
