Unfortunately, I hate micro USB with passion. Probably if it wasn’t on phones up to not long ago I wouldn’t have noticed how fragile (although not anywhere near mini USB) these connectors are. Amount of cables I had to throw away really got to me.
And USB C has been around for good few years now, I see no reason to be stuck with pretty antient solutions.
Happy to report that the mid mode of ~500 lumens is also perfectly regulated with an average efficacy of ~115 lm/W. Runs for 2.5 hours with a 3000mAh 30T.
If they fix this firmware and UI, it’s looking good.
Using high-quality micro-USB cables by Anker and the likes can be pretty reliable, though I am aware, (as one of my phones utilize the type-C now), the type-C is a design improvement with regards to reliable positive connection and more importantly, much higher charging rates.
I hope that they will upgrade the machining of the reflector in the production version, even if it does not improve performance much, it will look much better.
