The CTEK M Series range is a subset of the CTEK MXS series of 12 volt chargers. Available in 100W, 200W & 300W versions for meeting the needs of most applications in Marine or Motorhome, these units benefit from Eyelets instead of Alligator clips for direct installation to bus bars for distributed power, or connections directly to the top of house batteries. The units focus on comfort for the users by reducing noise from the internal fan by lowering the power output of the charger so the occupants can sleep well at night. And 8 hours later the unit returns to normal operation mode and continues charging at its full rate if the batteries still require topping up.
