Chunky high power keychain light
Added 2023-04-02 01:47:10 +0000 UTCI'll make a guess that this is a clone of another product, but there are so many copies of specific styles that it's hard to work out which came first.
It's rechargeable by USB C and has a 500mAh lithium cell.
The flashlight/torch has a momentary action turbo mode that drives the two front LEDs with 2A of current, giving off light you can feel as heat.

That is definitely an interesting little light. They developed quite a bit over the years. I can remember the mini maglight before LED became more uses in applications like this. I find the myriads of different head light LED lamps fascinating. Useful and durable stuff.
