Mastervolt ChargeMaster 24V 20 Amps 3 Outlets
Thanks to Mastervolt’s innovative 3-step+ charging process, batteries perform better and last longer. ChargeMaster guarantees fast and complete charging of your batteries no matter where you are.
ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2 and ChargeMaster 24/6). What’s more, you have the option for central, local or remote monitoring, configuration and control of your system.
