I've still not needed to charge mine since I got it, although it hasn't been my primary light. I do have another two on the way now though. The Tube won't replace all my other lights as I do need bigger/brighter lights at times, but it's certainly the best keyring light I have ever owned, and as a lightweight back up to my main light, or for days when I'm just relying on what's on the keyrings (Vic Manager and Gerber Dime), I can't find fault with it at all
