USB micro-B is a pretty widespread standard, compact AND inexpensive. An USB type-C connector is bigger, more complex and more expensive, without real advantages here besides reversibility.
In the past I replaced some USB micro-B male connectors for a sloppy friend in a DIY power bank with a permanently attached micro-B output cable, they can be bought rock bottom cheap with shells (and I've seen cheaper).
On the other hand, USB type-C male connectors: 5x pieces, 10x pieces. Without :facepalm: shells.
Of course the above is for comparison purposes, just made the type-C thing search out of curiosity. It serves as comparison because as it is understandable the female part cost is thereabouts.
I could say a chair or even the wheel are outdated. I like outdated stuff. ;-)
Devices are pushing the usb-c standard for a variety of reasons, and adoption is picking up. I have less and less need for micro-USB and have fewer and fewer of the cables hanging around. I wouldn't want a new light, which I'd expect to last years, to end up being my last darn micro-USB device.
Well people, this headlamp has been designed with a USB micro-B input port. I can understand all sorts of scaremonger reasons against, but in all honesty it is not my problem. I think and believe different. Nothing is random fellows. My ports do not break, I keep them fit and clean. If yours do, address the cause and/or fix the problem.
The headlamp could also been fitted with a standard O:) ∅3.5 × 1.3mm DC female plug, it could also have :-D worked with it. So, you can consider yourselves fortunate it uses a nowadays' more widespread and standardized USB micro-B connector. 0K, no more fuel to this fire of yours.
Despite Henrik's graph would probably match better if the NCR18650BL cell were have been tested on the newer 4-wire battery holder test station, capacity still does not match even if cell curve shape does.
So it is not an NCR18650BL. There are cells Henrik still have not tested, the one Sofirn is rewrapping could be some 3100mAh 0.2C rated cell from some known manufacturer like an NCR18650A, or from another OEM.
Thanks for chiming in Petr J., it is praiseworthy for Sofirn to preserve the original OEM wrap under their own; helps us consumers identify the product besides adding extra insulation.
That DLG “INR18650-B32” cell looks to use similar chemistry to that of the Sanyo GA/BL cells, with a little less capacity though. Good standard drain cell I'd say.
I like the light and tint, but I can’t understand why there’s no long click from off for moonlight. This light with an added moonlight mode only accessible from off would be perfect
