  • Compact and Lightweight – The CSW provides pure sine wave power from a small footprint designed to fit in tight vehicle and marine spaces. And it is lightweight, so won’t weigh you down.
  • At-a-Glance Status – The inverter’s status can be determined at a glance with the easy-to-read LED light.
  • Digital Display* – The alphanumeric display shows the inverter’s battery voltage, total AC output power, along with additional operation codes. (*not available on the CSW412)
  • USB Port – Power and charge your USB-enabled device with the available USB port.
  • GFCI AC Outlet – Plug in two pieces of equipment directly to the CSW and know that the GFCI outlet will quickly stop the flow of electricity should a ground fault occur. The outlet also comes with an LED indicator and test/reset capability.
  • Automatic Transfer Switch Option – The CSW2012-X automatically switches between shore power and inverter/battery power.
