I needed something to charge my laptop while on the road. This low-cost gem fills the bill perfectly. One annoyance though, if the engine is not running, the unit will emit an annoying high-pitched whine as a warning, I suppose, of voltage drop.

Turn off the ol' hearing aid, if you must and try this beauty.

I did a lot of research on this item, given the small price. Cobra in my mind had a lingering reputation for poor quality. I am quite satisfied with this product. I like the fact that it gives you the option of using a cigarette plug in or connection directly to the battery terminals to draw the DC power, and the plugs are quite easily swapped with two thumb screws. The directions did say not to power over 150 watts with the cigarette lighter. I'll take their word for it. But if this is the case, I think they need to understand that we need more than 2 feet of cord to get from the battery to the passenger compartment in any sort of installation. There is probably some technical reason behind them not wanting to provide longer cords that could melt or something......

Anyway, it pops right on after you flip the on switch, is quiet, and powers a variety of electronics just fine - laptop, dvd player, cell phone charger etc. It also comes with a well-built hard-side case for storage, which is a strong plus in my book. Otherwise you would just throw it in the trunk, crud would get into the outlets etc. Also, this inverter comes with two outlets for AC, that isn't clear from the picture.

My initial impression is one of extreme satisfaction, from design, packaging, quality and usability, it appears to be the real deal.
