I didn't get a chance to photo it today but it's a very basic site generator so I wouldn't recommend you run sensitive electronic items with it. We used it mainly for portable site flood lighting in the days before LED was widely available, nowadays we use a few rechargeable 50w LED floods which are a lot less bulky and less hassles so it's hardly been used for the last couple of years. It's also far from silent so it's not a good option for a domestic back-up solution, I thought Sparks might have wanted something for site power which was why I mentioned it.
