I have been using it for almost a month now. I have only powered small appliances so far with no problems. This inverter is heavy. There are other features as well which I can't use at the moment like connecting it to you mains so in case your battery is low it will automatically switchto it.One of the reasons I bought this is because of the connection output. I'm not limited to an 13A plug.The sellere repIied to my query quickly as well and re assuring.
