It’s in German, but the video reveals the basics.
The Manker U12 is being sold for some months now, and was it reviewed here. Seems a nice light 
The bigger one seems the replacement for the Manker U21. Let’s see how it behaves
BTW, this was one of the few YT channels I saw with more flashlight videos from the IWA 2018! I wish there were more, and I wish these channels also focused on the “smaller” lights (AA/14500s, 16340s, 18350s…). :zipper_mouth_face:
Acebeam W10 is also 21700.
Not that many good 21700 batteries yet though.
I hope it doesn't have that problematic electronic switch of U21 and when you need help to fix it Manker is not interested to help you out.
Hi, we always do our best to help our customers. But there were many users write to us ask for help with their copy model.
That is a pretty substantial downgrade in throw from the U21, especially since it only maintains 630 lumens.
any new models from the mk34 or 35 planning ?
