I saw that one too, I own the Jinheng 12A, I use it as my mobile phone charger and this one looks better: bigger reflector for better throw, better driven, available with three desirable leds, but best of all: the access ports are hidden behind a cap that screws on, so I guess the light is waterproof, which the Jinheng is certainly not.
Hank really is on top of some good products lately!
The Jinheng has problems with long batteries. Because there were no specs of its charging performance I wanted to have protected Panasonics in it, but I had to cut away almost the entire battery springs to squeeze them in.
The specs with this new light says that protected cells don't fit, and because the light comes with much more information I would trust unprotected batteries in it and have them charged with the inbuild charger. But I guess that the battery carrier has the same tolerances as the Jinheng, so with some fiddling I suppose you could get protected cells to fit.
I noted that they are in parallel. So because of that I understand it would be relatively safe to use unprotected cells to power the light, can charging still be dangerous however with this sort of setup?
For stock LED I didn’t test. But I changed to XM-L2 T6 3C on Noctigon XM20 MCPCB
2820lux @4M = 45120 cd
Flashlight : Build quality is good
7*7135 350mA = 2450mA
Lower is firefire mode
Fit with unprotected cells
Available for adding 7135chips , You can add many 7135chips to this driver board
USB Charger : not test.
I did notice the Fasttech one, despite cheaper in price but it comes with XM-L 1st gen LED, no cover for the charging ports and not-ideal mode group, hmmm.
