Stopped by Costco yesterday and saw a no-battery flashlight. Before Christmas I saw one at Fred Meyer and was going to buy it as a gift for camping trips but by the time I decided to buy it, they were out.
Anyway, it's a yellow thing labeled GEI INC. Has a squeeze handle and a switch, so I had to buy one. The instruction say you get about 3 minutes of light for each 30 seconds of squeezing. Damn it is bright. Probably not much good for wandering around the woods, but useful if the electricity goes out, and I can read by it which is more than I can say for the standard lights in my travel trailer. It must have a small capacity rechargeable battery in it. I squeezed it for about 30 seconds yesterday afternoon, checked how bright it was and turned it on for a few seconds several times during the evening. Still bright this morning and still bright tonight, so it is holding a charge. Cute, useful, and $8.
