I have found this one to be the best available and at a really good price. It's easy to use, and it has not failed me to date.
The best feature is the reversible polarity. In a rush or pinch you may grab an adapter with the wrong polarity by accident. Sure, it'll work, but you could definitely end up ruining your adapter and or the device you are powering up.
