I can't say about the durability because I can't get it to make anything work. I have tried using the suction machine with it~no power. It whirs and the little fan runs but what I needed it for didn't work. It might run a laptop or a video~I don't know I haven't tried that cause that wasn't what I bought it for. It is just layin in my back seat and I figure when I have my next yardsale it will be in it. But I'll have to make sure they try it on what they want to power first~cause I sure ain't giving them no guarantee.
