Utorch 1x AA 500+ Lumen Review

@kzb
It seems it’s not correct. Try this: Review : Utorch UT01 Flashlight (XP-L V6 / AA & 14500 / e-switch) First Post, at the end.
Does this work?

I’ve read it is possible to let the lamp be constantly in program mode. Then your instruction should work.

Thanks joechina I’ll try that tonight and report how I get on with it.

Hopefully when I get home some 14500 cells will have been delivered….

From off, just hold your power switch down and count to ten or less. It will blink once or it will blink twice depending on which mode driver is in. This is how you get between program mode and regular modes.

You want to see two blinks to enter program mode. Once there then do the double click and cycle through to adjust Low, Med, High, Turbo

There was one time I tried to re-program mine with a fairly depleted NiMH and it would not program. I forget exactly what it did though. I useda fully charged 14500 and it worked just I describe above. So, with a fully charged and healthy NiMH it should work just the same as a 14500.

Is this a re-branded Manker E11? Just wondering.

I believe it was cloned, not built by Manker. Although some of them seem to have the Manker brand on the internal components.
I have Xtar 14500 in mine and they fit fine. I haven’t tested run times. Mine had the bad switch also, the only thing gearbest would offer to do was a 50% refund, that was after they first offered a $3 refund.

Yes this works for me. Except I don’t think I’ve accessed the battery check.
So this method works with NiMH cell, at least to re-program the levels.
I was unable to discern any variation in the highest level though.

Still no Xtar 14500 batteries arrived. The flashlight arrived from China quicker than this.

The NIMH will not show variation in the highest level in my sample also. Normal, I should think, as the NIMH is probably not quite capable of the highet Turbo amperage that the driver demands. So it falls slightly short in that capacity.

However, the 14500’s should give you the flawless mode performance we all desire. :wink:

ETA: The programing modes are in this order. Strobe, sos, beacon, full turbo, battery check, and LMHT adjust mode. Full battery in battery check mode will give you 4 blinks. As battery discharges =’s fewer blinks etc

Most NIMH batteries do not provide the amps needed. I tried a few and the only ones of mine that work fine are eneloop (the white ones with blue printed name on it).

Thats ridiculous.

Did you pay via PayPal or a CC?

Bob

Yeah that’s what I thought too. Apparently returning a defective item for a refund is not an option either, at least not one they offered me. I may try and get the credit back through paypal instead.

Hopefully buyer used PayPal. File with PayPal and I’ll bet they change their tune. :wink:

They sent you a defective item. PayPal will be on your side. Total refund.

I would. You bought a brand new item. Besides, itjust emboldens them to do it to others.

Bob

Thats a sign of a depleted or well-used NiMH… that can’t deliver enough voltage under heavy load. On my lights there is a slight but noticeable difference between turbo and my next highest level. Its most visible on a ceiling bounce or outdoors. But then again, it needs a fully charged / healthy eneloop to achieve this.

Two Xtar Protected cells finally arrived.

Tried one in Utorch straight away. No response. Light does not work at all.

Tried the other cell, same result.

Charged both cells, tried again with both and still no joy.

Flashlight still operates fine on NiMH, but it refuses to do anything with the Xtar 14500’s. What gives?

Have you tried without the tailcap while bridging tube and battery with a wire?

This. The cells may be too long and preventing the contact between the end cap and the flashlight body. This would interrupt, or break, the circuit.

Bob

If the light turns on try the paperclip trick.

My UT01 just arrived, and it’s very impressive for 1xAA. I really like the mode selection and it’s enormously bright on high even with just a AA. I ordered a 14500, so I’ll let you guys know how that works out when it arrives.

This is what I am worried about. The Xtar protected 14500 cell IS marginally longer than the NiMH cell that DOES work.

I have tried screwing the tail cap down as hard as I dare. To me, it seems to screw all the way down.

Anyhow, there is no switch in the tail cap. Is it not just a spring contact, or is there more to it than that?
