[Review] Manker Quinlan U11 (XP-L V5, 1x 18650, Rechargeable)

Hell thomashf,

My unit has the microUSB conector nicely aligned-centered, and I can charge it using my smartphone adaptor (samsung) without problems. Looks like yours is missplaced. I suggest you contacting manufacturer regarding this issue.
Thanks!

Hello will34,

Actually, there is no stepdown. The big drop in the first minute you notice in the charts is the effect from the very first measurment (start-on) and the next datapoint used for drawing the line (15sec). My measurement setup can log data in 2Hz frequency, but for making my life easier my charts have 1 datapoint every 15 seconds of runtime.
If I have time I’ll share a 2Hz chart of the first minutes so you can understand what I am talking about. :wink:

Of course, this light has not a linear regulation with an output at 1000LM. Heat and voltage sag makes such things imposible in compact 1x 18650 lights with nowadays tech.

Well this is good! After reading your outstanding review, I thought I had missed the turbo step-down! I see what you are saying on the 15sec data collection frequency making it appear to have a step down, but it is the thermal and voltage sag, not an actual step down. Your data sampling rate just makes it look like a step down…

Great review on a solid little light, I do wish Manker would make a better clip, like the one on the Copper X5, for all their lights…

I see… Just an example, zebralights can drive the LED at full current as long as the temperature and input power allows it, but because the U11 does not have PID thermal regulation or a boost driver, I guess the driver simply pulls a constant amount of amps from the battery, the drop shown in the run time curve is actually decrease in battery voltage hence power. When they say constant current is the input current they refer to, not current to the LED. So If I’m right, the same tailcap current draw can be observed during the whole discharge.

here you go:

This is a 2Hz (two datapoints for every second) chart using the same log from the review, but cropped to just 300 seconds. Notice the line resolution is much better and smoother.

And now this is the first 15 seconds of the same log, In the review chart, there was only two of those points used for the line.
Hope you find it interesting. :wink:

Ordered this during the holiday sale from FT. Still waiting on it to ship. It’s now a race of two slow boats between The SC63 and the U11 to brighten my day.

Another excellent review UPz,I can’t wait to get mine.I prefer the manker to the mh-20 because it seems thinner and I like the flexibility of the “pro mode.”

Thanks for the lengthy review and pics!

Thank you! :slight_smile:

Thanks for sharing. Looks very nice.

Very well made!

Thanks!

Another great review on a nice light! Thanks for the hard work. :wink:

Does this light have a low voltage cut-off so I can use unprotected cells safely?

Great review!

I love my u11, I just wish it had a shortcut to turbo. I really miss that from my Olight S20 & S1.

i thought the brightness modes were saved and transferred over to the “general mode” too.

?

This is the best review about the U11. Thanks :slight_smile:

Does this light have a low voltage cut-off so I can use unprotected cells safely?

*—pretty sure it does, it definitely steps down from brightness levels that cause voltage to be too low
the firefly mode though would take 2 months to run down - if it got down that low :slight_smile:

==another buggy thing about it is, the ‘fuel gauge’ usually says 3 or 4 ‘bars’ out of 4, though it may still not be able to run turbo at all
this seems not very useful

Same thing with my first CW unit… it doesn’t run turbo. :frowning:

Great review, UPz :innocent:

I received mine yesterday… and I’m really liking it! :smiley:

I got the 5000K tint (I don’t like cool-whites) and everything’s good.
I like the fact that the moonlight is really moonlight, just like my [2012] TN12.
Yeah, it’s a bit fiddly removing the tail-cap with the supplied clip mounted; but it’s no big deal to me, since I’m gonna be charging the light
via the usb cable anyway. It’s stonking bright on turbo and the power levels are nicely spaced (not so with my TN12).

This is definitely one of my better buys :+1:
