5.0 out of 5 stars Great Universal Charger, June 20, 2010

This charger is designed for laptop batteries, so don't worry about being anemic on the power. The selector switch can pick 15, 16, 18, 18.5, 19, 19.5, 20, 22 and 24 volts power. Not only that, but there is a device to lock your selection so the switch doesn't accidentally move and fry your device. That is awesome!

After I received it, I discovered that the input voltage can vary all over the place, 120v, 240v, it really doesn't matter and the electronics sense the voltage supplied to the device. You can take this puppy to Europe, Africa, South America, just switch the standard input plug and you're good to go!

There are plenty of different output plugs to fit just about anything. I am very impressed with this great charger and doubly impressed by the price. The only thing that does not impress me is that the rating above asked me to rate the charger's battery life. That's food for thought...

Buy one. You won't be disappointed.

3.0 out of 5 stars Flexible, but not as comprehensive as advertised, August 1, 2011

This review is from: Universal AC Adapter 15V 16V 18V 18.5V 19V 19.5V 20V 22V 24V 70W (Electronics)

This adapter offers a variety of tips and a variety of voltages. There is a switch that can be used to set the voltage, some rubber inserts that will keep the switch in any give position, and a rubber cover for the switch, making the rubber inserts unnecessary. I don't know why they bothered giving both, but it can't hurt.

The power supply is as accurate as you could expect for its design. The output will be in proportion to your AC voltage, which will vary a bit from place to place. If you look at the picture (enlarge as much as possible) you will see a switch that shows available voltages. The instructions list others, such as 19 volts, that are not really there. What they should be telling you is that the device is suitable for 19V uses, since electronic devices have a degree of tolerance. Although the device is suitable for the uses it implies, has the correct tips for the devices it claims to support, and has voltage settings that are within the range of any of the ones listed, it can't technically be set for some of the voltages listed. Even though it's unlikely to make a real world difference, I still have to downgrade it by a star for that. It will confuse customers.

DC devices such as computers run on batteries or can use a power adapter to provide equivalent voltage. When batteries are used, the voltage drops over time, and the batteries can die completely. So having a power setting that's a half volt under what you were expecting is far less of a deviation than your computer is designed for, but for charging purposes, the optimal settings are the one that the computer was designed for, which are the ones for the factory power supply.

This was the second charger I bought in a month. This brand works a lot better than the other cheap one I bought. I definitely recommend it. Only downfall is that it sticks straight out of my laptop about an inch.... can't beat the price though
