Detachable head torch power bank.

This 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!

It 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?

I looked to see if you can buy them seperately with no luck.

That detachable torch looked neat. Was it all metal or mostly plastic?

I've got a big head and this one fits comfortably.

Does 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.

If your 18650 batteries don’t have the pip and you need the pip, add a small magnet on the end. I also used this to chain some batteries for tests.
