Great for my Laptop Dv7
This inverter is working good for me so far. I have only been using it for about a week now and it is charging my phone and lap top and I even used the AC outlet on it to charge a battery for my small cordless drill and cordless LED light. So basically it is doing exactly what I purchased it for.
Does as specified, also unlisted is it has either a ground loop isolator or a noise filter, when charging a device that is plugged into the radio (headphone out to aux in) there is no alternator noise/whine. no fan built in so its completely silent.
