Got this to put in my little RV. I was looking for something small enough to not draw downthe one battery I have in the Coach. Installed under a cabinet close to the battery andran 10 ga wire to it. Plug in the Coach electrical cord to it and turned it on. It willrun a Radio or TV or the Microwave or the Fan in my A/C but not the A/C itself which wouldtake about a 3000 watt inverter which would drain my battery really fast! I watched TV andlistened to the radio for 2 days and finally ran the battery down running the A/C fan on thesecond day. It's a little workhorse. Good for the price too!
