Re: *new* Olight Smini
does it have a magnet in tail ?
can it be USB recharged ?
no ? hmm.
I remember having had a discussion regarding the "tail magnet" of the Smini Ti but can't find the discussion, maybe it was on another forum. Users explained to me that my off the top of the head memory of the Smini was wrong and corrected me saying that the Smini does not have a magnet (while the Olight H1 Nova does). Both the
H1 Nova and the
Smini Ti do have a "black ring" in the tail cap, that's a fact!, i had remembered that fact correctly, which is why i had thought erroneously that the Smini had a magnetic tailcap too in the first place.
I've been using the Smini Ti as
my primary EDC light since i got it 4.0 years ago, still running strong! But only today did i realize what the black non-magnetic ring is for. lol :laughing:
I put in a 16340 battery the wrong way, tried to turn on the light, and was shocked about my mistake
.. since i remembered ppl on the WWW claiming that the electronic reverse polarity protection (ERPP) on some Olight model wasn't reliable. And iirc, the documentation/manual/marketing never advertised that the Smini has ERPP (or can you find a quote?). Be it as it may, did i just test the ERPP and possibly ruin the light?
When i opened the tailcap, i realized that the falsely inserted 16340, its (-)pole, never made electrical contact with the titanium! Because of the black ring inside the cap. So even if the Smini has ERPP, it was not tested by this incident. I did not ruin the light through my mistake, what a relief.
There you have it, long story short. The black ring in the Smini tailcap is not a magnet but functions as
mechanical reverse polarity protection (MRPP). Most of you owners were probably aware of that, i really wasn't.
Nobody told me. Olight didn't list it as feature. :shakehead
Back then I had thought that the black ring was useless, *gly, and poorly made (black foam? black soft plastic? black ****?), and i wanted to pull/peel it off. Am glad that i let it sit there, that i let :hahaha:it alone, unharmed, untouched.
Anyway, that's good news for Smini Ti owners: We doht need to be concerned about wrong polarity 16340 battery insertion, hooray! :twothumbs
Same goes for the H1 Nova apparently: a
reviewer claims that the "foam donut" and the tail magnet are separate entities (so the black ring in the H1 Nova tailcap isn't a black magnetic ring either!). He doesn't sound too sure, though, also because the MRPP is nowhere mentioned by Olight company. But we can take the situation at face value: Both the H1 Nova and the Smini Ti seem to have MRPP through the black donut, great! And since MRPP is present, these Olights doht need to have ERPP in addition. (
we're not sure if they have ERPP, are we? it's nowhere advertised as feature)
That makes me wonder why the folks at Zebralight couldn't add MRPP to my ZL AA flashlight. Actually, thinking about it now, i could try to add MRPP to that AA light myself, a nice mod. I just need to find a black plastic/foam donut and try to glue/tape it deep down there. ( EDIT1:
done! :kiss: )
EDIT2: I checked. The pseudo-compressible black ring of the H1 Nova is very thin (low). It's not a "foam donut" but prolly made out of the same black plastic material as seen in the Smini Ti. The "problem" is the extremely tight clearance between the magnet and the donut, i measured
0.1-0.2mm, crazy. If your 16340 battery has a bulged out (-)pole and the magnet has moved out of its glued/fitted(?) position, then there could be electrical contact. So i modded the H1 Nova tailcap as well by adding another
+0.25mm layer for a total of
0.35-0.45mm safety clearance:
