Review: Trustfire Mini-01

Glad I picked up the Yetzl cells…

:smiley:

Now i just need to get hold of an AW IMR 16340. That should be really fun :bigsmile:

Good one. Should be interesting J)

Is the AW IMR better than the Yetzl? By how much?

I don’t know enough about flashlights and batteries to give a definite answer, but this is what i think: I bought the Yezl 16340 because it has the highest tested capacity ive seen, and it is rated to handle upto 3.2A discharge, which, from what i can tell, is very good for a 16340 cell.
The AW IMR 16340 is capable of 4.4A max discharge, but will also have a much lower internal resistance due to design and lack of any protection circuit. This means it will perform better in a light that needs high current delivery, especially a direct drive light like the Mini-01 seems to be.
So in theory, the AW IMR 16340 should make the Mini-01 even brighter. You would just have to take care not to let the IMR discharge below 2.5v(as it has no protection circuit), or it will shorten cell life.

Thanks Matt

As soon as mine arrives I will post figures using my TF flames as well as OTF lumens in my IS.

Flames work fine in mine. They’re from DX.

Thanks :slight_smile:

Yes, the Trustfire flames 880mAh seem to be a good 16340 also. Torchythebatteryboy tested them as having 658mAh capacity at 1A discharge.

So I heard it last 6-8 minutes on high. How much do i get with these AW & Yezl cells?

I haven’t really done run time testing because it gets too hot on high after a minute. After several bursts in high, it gets easier to leave on for a bit longer as the cell runs out because the light doesn’t get as hot.
I’ve also only ran the yezl down to 3.6v.

Using a primary or LifeP04, the light doesn’t get nearly as hot so can be left on for 5 minutes, maybe more, and I got at least 20 minutes run time, but haven’t tested properly.

EDIT: you will have to be careful if using any unprotected cells as the light can drain them quickly and may over discharge. I accidentally ran a LifeP04 down to 0.8v while testing the Mini-01. It seemed ok though and charged back up again.

I have just tested edited my previous post above to include 2 more current draw tests using 18650 cells :bigsmile:

The Panasonic batts must give out significant light than the Yetzl… Does it make a huge difference?

I didn’t really get to look at the output because of the way i had the head setup(face down) measuring the current. There was serious heat in the head after the little time i spent testing though, and i lifted the edge of the head up slightly to see the output and it was really bright :bigsmile:
I wonder would an IMR 16340 be as bright?

I suppose looking at it realistically, making the Mini-01 any brighter than the Yezl already does will make it too hot to handle in less than a minute or so.

I just received the Trustfire Mini-01today. My first impression is how small, well made and very bright this little torch is.
I can’t quite comment any more on this light as others have pretty much covered every angle when it comes to build and quality.

It is impressively bright with the 3.7V 16340 Yetzl. Because I will be using the Yezl battery I may just end up shortening the inner spring by 2mm as I find the fit just a little tight.

This is certainly a must have addition to a flashaholics collection.

An XM-L LED in a very small body is a win situation.

I use the Trustfire protected 16340 and hand hold it with no problems.

Good to hear your Mini-01 arrived and your pleased with it.

Let us know how you get on if you choose to shorten the spring.

The trick will be to shorten the spring and twist the top as well to ensure a good connection.
I also find that the threads are completely dry.
Other than silicone lube what else can be used? I ran out of silicone so I hate to wait it out another two weeks to receive in the mail.

I’m not sure what else to use to be honest. I put silicone on my light when it arrived, then cleaned it off after a day or 2 and applied more because there seemed to be dirt from the manufacturing process on the threads.

I also found that the pill/reflector was screwed slightly too far into the head. This meant that the light had to be screwed as tight as it could be to turn the light on. So i unscrewed the pill slightly and it makes activation of the light much easier.
