It feels like it's of pretty high quality. One of the reasons why I am particularly happy with it is that I bought it for about $16:-D (price mistake?). I'm running my laptop off of it currently (dell 15 inch with discrete graphics) and it hasn't even gotten warm. I haven't been able to get the fan to turn on, hopefully the loads I've used it for are too low and it's not actually broken.
It comes with both a cigarette adapter and alligator clips for connecting directly to a car battery (or other DC source). I like that it has 2 plugs, though it would be nice to have an USB plug also...but I can't complain:).
Anyways, I don't think I would have bought it for $40, but it's definitely worth that much (I'm just cheap)This item seems to ship for PA, it only took 2 days to arrive.
It comes in a blister pack and is surprisingly small, included is a tiny 19 page manual, 32" Direct to battery cord with medium sized alligator clamps, and a 32" inch cord with a cigarette lighter plug, and of course the inverter unit itself. The dimensions of the unit are 5"L by 2" high by 3.5" wide.
Tested using a small 8Amp 12v SLA AGM battery.
The unit's manual specifies that the Low Battery alarm will sound at 10.7 volts, however it's actually 11.00 volts. The alarm can not be turned off, so I did not experiment to see what voltage the unit would cut off at. At the Battery Cut Off voltage specified in the manual (10 Volts) your battery would be destroyed. However it's unlikely anyone would be leave the thing running for that long, without noticing the VERY LOUD alarm. a typical car battery probably has at least 300-600watts of storage (for one hour), and is recharged faster then the inverter could deplete it if the car is running.
The internal fan never came on, the manual specifies it will only come on under a load of 100watts. i've only tested a 60watt laptop and it ran without any problems, with the inverter only becoming warm.
I don't see anyone having trouble drawing 300 watts from a car battery due to the batteries voltage drop under load, I tested a 0.7v drop under heavy load with a tiny 8Amp SLA battery for lamp, there were no problems powering electronic equipment.

So, in summery, the alarm sounds at a reasonable battery voltage, but the cut off voltage is useless. The device does not draw an appreciable current while idle, but you might want to disconnect it when not in use anyway to protect the cars battery during extended storage of the car (-5Amps/day). This is a pretty awesome product for a $20 inverter, but it's probably not really all that wise to run sensitive electronics on it for long periods of time, you know, like days.

If you have any questions i'll probably reply to them here.I have had this inverter for about a year now. it still works like new (Knock on wood). I have no problems with it.I have this guy permanently installed in my car. It's never drained the battery, and has always worked. I have my car charger plugged into it all the time, and although my cell gets warm when charging, it's never hurt anything. It beeps when I turn my car on, but otherwise I never even know it's there.

I bought this item to inflate tubes using an AC powered inflator using only 1.8 Amps, well under the rating for the device. I connected the converter directly to the battery as required in this situation, and correctly had the polarity of the connections in place. Upon turning the power switch on, I heard a pop and it was totally dead. I'd give this zero stars but chose one star since that seems to be the lowest one that has a description associated to it. I do not recommend that anyone buys it. I am not even bothering to return it since the cost is not worth the time, effort an shipping costs involved.
