Pros: Great size... fits into any cup holder. Soft start feature will certainly save some fuses. The USB port is a great feature in the car if you have a device that needs charging.

Cons: At night the LED is a bit too bright... but you can place something over that if needed (but don't block the vents). If you have enough cord you can place it in one of the back seats cup holders to dim out the light from the LED.

Overall Review: I bought this to replace a 12V car powersupply for my netbook which lasted only 2 uses. I would not recommend the 12V adapters, instead use this device and use your regular power adapter instead, it is much more reliable.

Pros: Does what it is supposed to.

Cons: None.

Overall Review: I ended up cutting off the car plug end and put alligator clips on it. I wanted to use it in a go-bag type situation. Tested it with 12 volt UPS battery and worked great. I already have a plug in my car.

Pros: Silent. Has enough juice to power my laptop, cell phone, and MP3 player simultaneously. The blue indicator light is bright enough to be seen in the daytime but doesn't distract me at night.Silent. Has enough juice to power my laptop, cell phone, and MP3 player simultaneously. The blue indicator light is bright enough to be seen in the daytime but doesn't distract me at night.

Cons: The manual says the continuous output power rating is only 120W (and 20 minutes at 150W). However, the details tab states 150W continuous (take note Newegg).

Overall Review: Output may be limit by the car's fuse -- my 2010 Camry has 10A. The calculation is as follows for the maximum I can get (with motor running): 14V x 10A = 140W x .85 (85 percent is the efficiency rating stated in the manual) = 119W. Also, a 10A fuse wouldn’t last very long if run at 10A; drop the input down to a 9A and the max output becomes 107W. FYI - the inverter itself includes a 15A fuse in the plug. In actuality, you may not need as many Watts as you think. My Lenovo G530 states "120V, 1.5 Amps" (180W) but uses only 45W when on with a half-charged battery. A "P3 Kill A Watt" type meter can determine your needs.

Pros: It's...a power inverter...that fits in your cupholder....seriously, everyone needs this product...at least until the car companies wake up and actually start integrating them...

Cons: Whiny fan, so what, turn up the stereo.

Overall Review: Consult the product you are plugging into this unit before making charcoal. Pay attention to the power draw...you'd be surprised how much power things like hair dryers will pull. But if you're using the hair dryer in the car...you have other problems.

Pros: It's worked with every device i've plugged it into

Cons: USB port doesn't work with iPhones.

Pros: Light, resistant to cold and wet conditions, cheap, the USB port is genius!

Cons: Just slightly smaller than the cup holders

Overall Review: In the cascades I used this can inverter (hoocked to a car battery in a sled) to power a video projector for an art project, all during a major storm. It is incredibly light, it was exposed to very cold temperatures for three days and was subsequently covered in snow.

Pros: Dead silent - no fan yet never runs hot. Good power, even surge at startup. Was easily able to power a 19" tv in our RV daily for two months with no problem.

Cons: Wish I could find something twice this capacity that still had no fan. Obviously this is not a con of this inverter, more like a suggestion to Rosewill.

Overall Review: Have always had good luck with all sorts of Rosewill products from mice to hard drive enclosures.

Pros: I have had this inverter for over a year and it has fulfilled its purpose in every way. I recently took it car camping so that I could use the fast, electric air pump for my mattress. We use it to power laptops on long trips and pretty much anything else we want to plug in. It is quiet, durable, and easily worth the price especially if you're able to land the occasional <$20 sale.

Cons: None: This product successfully fulfills all the purposes of its design. I love it.
