This is a great product. It is perfect in (almost) every way. Smallest 150 watt inverter around. Very quiet. Works both in the car and on a plane. Has both a 3-prong AC and USB powerpoints. It shines particularly well verses the 'big-black' inverters for traveling for 3 reasons. 1) Again, it is so quiet that more often than not you can't even hear it; 2) when you re-start the ignition on your car it properly resets itself and keeps providing power (unlike the 'big-black' units which are universally dumb and unpower themselves); 3) if your car's battery voltage drops (because it is cold...older battery...or you are not running the engine) this unit tends to keep working whereas most others sense the voltage drop and quit working. The only minor quirk with it is that the silver-tipped spring that you insert into the lighter socket is overly sprung and in some cars you need to occasionally re-push it into the lighter. An annoyance but not a deal breaker. Overall I cannot recommend this enough. The only other unit that comes close is the Xantrex 175 watt unit (#813-0291). It has all of the above qualities except that the airline portion of the adapter would not seperate correctly from the cigarette portion of its cord. This resulted in the unit's tip being slightly loose at the plastic seem of the cigarette portion of the adapter.

Get this adapter for your laptop! I tried two other adapters and they failed to support the load on my Sony Vaio Z series laptop adapter. Plus it comes with a nice little case and has the airline adapter. There are two fuses one in the tip and one in the adapter to help keep things safe. Highly Recommended!

I spent an absurd amount of time comparing the different inverters on Amazon and finally decided on this one. I'm glad I did, and I am a very persnickety designer. Unlike some of the other ones I was looking at, this one has a clean, slim design. Most inverters must be triple or quadruple the size and weight, if not more! This one is light and tiny, about half the size of a small paperback book, if even that. The plastic it is made out of is the high quality impact resistant stuff, not the fragile junk I was half expecting. The cord is detachable and is just right to keep the inverter out of the way of things like your shifter, but not too long that it's messy. The product comes with this nice little case for the inverter and cord which is pretty handy, perfect for storing it in the glove box. I just got it but have tested it out and it was charging my laptop. I recommend going with this one, you will be happy.

The product is great overall. Incredibly small for inverters (will be perfect for flying with my laptop), the power is not underrated, and the pouch it comes in is very handy.

The only downside is that it is noisy. I've heard noisier inverters, but this thing is far from silent. I can hear the cooling fan distinctly over my car's engine and road nice (and I have a pretty loud car).

Overall still happy with the product. I needed an inexpensive, compact power inverter that can be used in a car and on a plane.

First of all, it works. There aren't too many 150 watt inverters out there, so the fact that this is one, and it works, should be more than enough to buy.

Other pro's are that it is a good price, and it also includes a USB port so you can charge ipods/smartphones without any other coversion devices.

I used this for several hours with my 120 Watt quad core laptop on the road. I turned the power settings down as low as I could just to be sure I didn't fry something, but I had no problems. It gets a little warm, but not too bad. Yes there is a fan, and yes you can hear it, but it isn't really annoying.

The biggest area for improvement would be the length of the cord. It isn't super long, but I have been able to charge my phone off this while sitting in the back seat, you just have to have a long enough cord.

I would buy it again.

UPDATE: I've had this for about a year and a half now, and I've decided to take a star away. I don't use this thing all the time but it is starting to make some bizarre noises. Still a good product though.
