2-in-1 Car and Airplane Laptop Power Adapter

Pros: It work as it's said but power not strong.

Cons: Nil

Other: Consider of buying if you got addtional cash to spend.

Pros: Runs very cool under typical conditions
Good DC power plug retention when inserted into laptop
No heavier or bulkier than similar AC adaptor

Cons: Shielding against Radio Frequency Interference could be better (produces some noise on AM broadcast band)
Needs a Velcro strap for winding power cords around adaptor housing

Other: Well worth the money!

Pros: It works. The current is stable. I was able to use in an airplane and I use it a lot in my car between meetings. I tested the current and it is stable with out peaks that could harm your laptop.

Cons: build quality is not good. after I used it in an airplane I found that the piece that goes into your car socket is broken to pieces. I had to glue the whole thing back.
So don't play with it too much.

Other: it's a good product. build quality needs improvement and fast. still, in the overall experience I'm happy.

Pros: Only had it one day and it works perfectly in the car powering an msi wind netbook but will try and test it more. The quality actually seems pretty good which I didn't expect. Its a great price, most of these units usually sell for about $60 or more.
Not sure if it works in a plane yet but im assuming it will.

Cons: Nothing so far but with something like this I think only time can tell. I got it to take on world trip in about 6 weeks and if it lasts the trip I will be happy with that but will be good if it lasts longer.

Other: If you need to power your device and are travelling with an airline that supports empower inflight power and also using a car during your trip and dont want to buy one of the expensive alternative items then this is the item for you!

Pros: - very good build quality (I didn't even expect it!) - no noise - stable 20V output

Cons: - about 80% efficiency measured (1.65A/12V input, 0.75A/20V output) - can be a little bit cheaper, but 17$ is not a over-priced

Other: The connectors in package will be suitable for a lot of notebooks, I think. Really recommend this unit for notebook in your ca? or carputer - small, quiet and cold power supply.
