Used by me for a total of about 50 hours while inside my Prius, for charging my first ebike while on the road. I got a different e bike that has a much larger battery so also a larger inverter, thus the sale. MorningStar has long been considered the best in long term reliability and efficiency this is a high featured (LVD and connections for a remote control as one example) little inverter. The best price I could find for a new one was about $325.00, I'll sell this one for $150.00, buyer pays for the shipping. My zip is 83245.
