Can you run a USB rechargeable headlight off a backup battery?
I'm in the market for a new light, and it seems like most of the nice ones these days are USB rechargeable. My current light takes AAs. I like the fact that I can keep some spare batteries in the seat bag or stop at a convenience store and pick some up when I'm out and about at night and it dies. I will definitely be in that situation again at some point. I have a small USB backup battery for charging cell phones, so I thought maybe I could use it to run a USB light off of until I got home to give it a proper charge? Has anyone tried this?
