Universal Car Cigarette Powered Adapter/Charger for Laptop/Cell Phone/PDA/GPS

Pros: - It's a great power supply as you can adjust the voltage
- It comes with a lot of connectors and options
- You can reverse polarity by switching the pins on the terminal connector, giving you a wide possibility to connect a large amount of devices
- It has a normal USB port, convenient for charging a mobile phone, PDA, etc. which is rated to 1 Amp.

Cons: - None i could find

Other: - It's easy to use, supplies ~ 80W of power, enough to run most of normal laptop computers and even recharge the batteries (for example my Dell laptop uses a 65W power supply).

Pros: this is a great gadget for me because i use it with 12 volt car batterys whitch charge from the sun (solar panels 34 watt),and this works my laptop (acer 5738g) .

Cons: there is a wrong in the dx list for this product it says 19 volt 3,3 amper the truth is 4 amper at 19 volt and 3,3 amper at 20 volt you can see it on the buck of the converter nothing else !

Other: for what i expect is just great !!! i put it with my 12 volt car battery and works with my laptop 70 watt !
