This is smaller than I imagined it (yeah, I know, the photo shows how small it is), so it fits nicely in the rear of my mid-sized SUV. I have not used it much yet, but I picked this up so I could recharge camera batteries, attached to a small 4-outlet power strip. In its limited use so far, it has worked perfectly.
Works absolutely great. I used mine every day for about 2 months then got my girlfriend one on sale for less than 15 bucks. You do need to remember to not leave the inverter plugged into your car while you turn it on or the surge of electricity from your car starting can overload the inverter and cause it to fail. I just got into the habit of unplugging and plugging it back in and it has been working great.
