Detachable head torch power bank.
Added 2019-01-13 05:58:32 +0000 UTCThis seems fitting after several people mentioned this style of USB flashlight converter. I got this a while back, but they still sell them.

It's interesting in that it's a head torch that doubles up as a low current <800mA power bank.

The little flashing red LED on the back might be for use by cyclists as a sort of rear light. A bit pathetic as such and certainly not conforming with any legislation, but you see quite a lot of cyclists using headlamps instead of the regular bike illumination. Nice lamp, though. Might as well order one!
2019-01-14 23:15:12 +0000 UTCIt looks like there might be room to add a tiny decoupling capacitor across the solder pads for the boost circuit input... Would that have much effect on the voltage drop-off?

2019-01-13 20:17:26 +0000 UTCI looked to see if you can buy them seperately with no luck.
2019-01-13 12:24:59 +0000 UTCThat detachable torch looked neat. Was it all metal or mostly plastic?
2019-01-13 11:21:35 +0000 UTCI've got a big head and this one fits comfortably.

2019-01-13 07:24:10 +0000 UTCDoes the headband actually fit a Westerner’s head? I’ve had quite a few Chinese head torches and they were so tight that my head is now hourglass shaped.
