This runs and has started on the 1st pull for me, just ran it for 45 minutes yesterday,  the DC charging side puts out 20 volts ,these were made for charging car batteries as the Dc side of these have unregulated voltage so that is why the voltage is higher than 12 volts, they used these on boats ,helicopters and any vehicle or rv that need a battery charged, it does not come with the charging cable, you can buy them for around 12.00 last time I bought one. When I bought it the man I bought it from said the AC side needed a new fuse, I tried to remove the fuse holder cap and the screw driver slot is pretty stripped out, so i have no way of knowing If the AC side works, I am vision impaired so no longer work on small motors, it has the small dent onto the top edge where my finger is pointing.  You can see the green light working on the left side when it is running.  Again it runs and idles but is being sold as is for parts are repair because I cannot test the ac side. So please see the pictures and judge it for yourself as they are part of the description.  We use heavy bubble wrap and packaging peanuts and the proper cartons to get it to you undamaged,  IT WILL BE DRAINED OF FUEL AND MOTOR OIL,SO YOU WILL NEED TO ADD OIL TO IT BEFORE YOU START IT , IT WILL BE DRY OF OIL AS I CANNOT SHIP IT WITH FLUID IN IT. thanks for looking and God Bless America and our Troops
