This product does exactly what was stated on the literature. I used it on a trip to power a theraputic cold water pump in the car and everything worked per specification. A second power cord (besides the standard vehicle power point design) based on direct battery connection via clamps was also provided and I consider this a bonus to be used if a battery is not installed in a vehicle.

My main worry for this product before I bought it was the many reviews that it did not power their laptops, I bought this mainly for that purpose. I have a 65W dell laptop and it powered it up without problems. I tried playing movies and everything and it maintained charging state. Worries put to rest. Pretty good product in my option. Slim so very easy to store, and becomes warm to the touch when in use but not hot. <br/> <br/>Edit: (Jan 5, 2011). Took this product on a 10 day road trip. Used it for hours with no problems encountered. One thing I noticed, sometimes when I hit the brakes, the unit will for a split second toggle to red (no charge) and back to blue (charge). It happened on a rental van I was driving but not on our CRV.

Only used it for 30 mins. or so at time. Worked well charging my daughters cell phone and ran my Sony Vaio laptop just fine.

I haven't used too many power inverters, but I'm surprised at how incredibly small, light and generally unintrusive this unit is. <br/> <br/>Bought it in time for our 10-day Christmas-to-New Year's road trip. We spent a good deal of time driving and had a GPS and either a smartphone or laptop hooked up to it most of the time ... worked just fine. <br/> <br/>Con: the cable from the lighter jack to the unit is not too long, so depending on the placement of things in your car you might not be able to find a good place to put the unit itself. It worked fine in our car (Infiniti G20) and my parents' car (Ford Explorer), though. <br/> <br/>Another thing: the advertised power (175W) is actually peak power ... continuous power is more like 130W. If you draw 175W for an extended period of time it might overheat (haven't tried it myself).
