Here is the U12: The design is the same of the U11, but the U12 is slightly longer and wider.



Here with the 20700 4250mAh battery

And with a 18650

At the head there is the single stage electronic switch and the USB-C port for recharging the battery.


Now the LED under the switch stays always on bot as a locator and a battery meter.

The light only removable part is the tailcap.

The anodized, clear cut threads at the tailcap, that hosts a double nested golden spring.

On my sample the spring assembly fell out because it wasn’t glued. Manker told me they forgot to add glue to my sample.

At the head, the contact point for the positive pole of the cell is a golden spring.

With the U11, the slimmer and less powerful version (note that on my U11 I replaced the original CW XP-L emitter with a XP-L Hi Warm)



The UI

1. Blue: More than 75%
2. Purple: 50%
3. Red: Less than 20%
One click – double – triple from any mode to lock out the flashlight. (Only the battery indicator works when lock out)
Long press for off and still hold on, the side button batttery indicator will turn on and then quick click for 4 times to get access to engineering mode. One click to check different level and long press to make your final choice.
Output and runtime

My thoughts

I hope to just had an unlucky sample, and I am awaiting your feedbacks guys.
This means that, compared to all the other 18650 powered lights, the U12 will have a longer runtime. The output is well regulated (as in flat) for the tested outputs.
I don’t know many EDC lights that can sustain a 1000ish lumen output continuously.
The sheath pouch has a flap that should have been a bit longer.



If Manker has fixed all these small mistakes on the production run, the U12 is a solid candidate as an EDC with a slightly larger size, but that packs a lot of output and runtime (the 20700 basically holds as much energy as a 18650 + a RCR cell).
