You do not need to remove the Rack Shower from your vehicle in order to charge it. The Rack Shower’s included 12v power cord is 8 feet long and if needed, you can purchase a separate 12v power cord extender to adapt to your vehicle's length. Otherwise, if you don’t want to worry about charging, you can have power constantly flowing to your Rack Shower by plugging it into the SAE plug located at the bottom of the Rack Shower.
