I´ve got an Everlight. It can be charged in about half a minute and hold enough charge for a few days. The beam is bright enough for about 10 to 15 feet. The advantage is that I don´t have to worry about batteries to be empty or leak. The downsides are the short operation time (3-5 min) and the strong magnet. You better keep it away from your cards with magnetic strips. My compass deviats up to 6 degrees when the light comes in a two feet range of it. So unlike other flashlights you can´t use it to work with map and compass.
