I call it rechargeable lamp but the store attendant said it is called Emergency Lamp. Anyway, I bought one that costs a little over $10 and tested it when I came home. It said the charge is good for 20 hours so I left it working overnight. Lo and behold it was still working on the next morning. With that bench marking, I bought another one. This emergency lamp is good for camping purposes because the luminosity can be adjusted. And it has a built in solar charger although I haven't tested it yet.
In the pic below are the 2 yellow lamps that are good. The green runs for 2 hours only.
