    I already had one of these inverters but, unfortunately, was on vacation and 12 hours from home when I realized I had forgotten to pack it. I didn’t hesitate to buy another one because I personally knew the quality and longevity of this product. Naturally this was the only option and now I have one that stays packed with my travel bag and the other stays in my vehicle.

    Doesn’t charge laptop

    I returned the product 10 minutes after I purchased it. Reason being is that I purchased for laptop charging in my car and in fact it does not complete this task. It sends my laptop into a never ending loop of silent, power, charging, battery low in that order. It also made my car sound like r2d2 with a whole lot of extra sounds coming through my speaker.

    This product did not really do much of what I wanted it to do. I was hoping it would allow me to plug in my laptop while sitting in the passenger seat on a road trip. The appliance did not hold enough power to keep my laptop charged. That could just mean that it really isn't intended for that type of use so it might not be a fair expectation. However, when I had spoke with a best buy representative, he gave the impression that it should work. I ended up returning it when I reached my destination due to the fact it didn't do what I was hoping.

    the three prong on my mac power cord has a hard time making it into the receptacle here. very tight fit and hard to insert and remove. something is going to give sooner than later. and hopefully not the expensive power cord. Wont buy this brand of adapter again.

    Went to store and asked a salesperson for cordless external battery backup for laptop to use when there’s no where to plug into electricity. He sold me this. It’s for a car! Not useful at all.
