 worked fine for a month November 11, 2009

I really loved this while it worked but alas after just over a month of use it just stopped working. Now when it is plugged in it makes a continuous high pitched annoying noise and doesn't charge anything.
very disappointed because I was really enjoying the convenience
 Does the job well November 3, 2009

So far no problems with it. Only thing is as some people mentioned, the heat vent is at the bottom, so I'm not sure if you're supposed to put it in a cup holder or not. Which makes it pretty stupid to shape it in a cup. But work-wise, it's awesome.
One minor complaint, the top of the cap is a bit weak. As I was unplugging one of the devices, the cap broke one of the hinges, so I taped the thing shut. It was a bit of a violent pull, but I'd expect it not to happen nonetheless.
 Very handy. Just what I was hoping for. October 9, 2009

I really like this product. I originally got it so that I could recharge my video camera while I'm on one of my offroad adventures. Instead of wasting money to buy new camera batteries, I just got the Power Line Coffee Cup Inverter and it does the job well. I especially like the USB outlet. I've used it to charge my mp3 player while on my way to the gym and it worked fine.
It can't be used for any heavy-duty devices, like an air pump for a camping mattress, but I've used it with my laptop and a few other low wattage devices and it's been very reliable. I bought an 800 watt inverter that I bring with me for other higher power needs, but this one is great to keep in the vehicle for charging phones, cameras, mp3 players, laptops and similar devices.
I agree with another review that the design really isn't going to fool anybody looking into your vehicle. It's obvious from the outlets that it isn't a coffee cup. But the novelty of the design is more of a functional thing that a security thing. It fits well into a cup holder and that keeps it steady and close to my Jeep's power outlets.
The "lid" on mine didn't seem like it was completely attached when I took it out of the package. But I just pressed down on it and it snapped shut and I haven't had a problem with it since.
Died quickly (again) September 29, 2009

This worked for maybe 20 minutes, but after that, any time I so much as plugged this unit into the car's outlet, the car's fuse would immediately blow (even with nothing plugged into the inverter).
The concept is great, having a place to put the inverter that is convenient and doesn't dangle or shift around, yet also isn't a big device that has to plug right into the accessory outlet (which isn't always placed to facilitate a device like this, and also precludes being able to simultaneously use the outlet to power anything else.) And enough people have left good reviews that I assume they're not all so prone to quick failure. Nevertheless, I will not buy another PowerLine. I previously had the PowerLine 0900-36A which also failed (though I did get more than 20 minutes out of it). So I just don't consider them reliable, and I don't know how long other reviewers have had their units.
Luckily, there are numerous other cup-holder-sized inverters to choose from, just do an amazon search for "inverter cup"
Great for long haul road trips with computer and mp3 July 23, 2009

My family used this for over 8 hours to and from our vacation with great success. The cord was long enough for it to be plugged in the front and used in the back seat. I used it to power the laptop while my wife drove then later to recharge the MP3 while she slept. The unit does make some noise when the internal fan is on to cool the device however that sound is only noticeable when the car it off and then barely. I highly recommend the product.
