I was wondering: you can feed the Fenix CL25R two CR123A’s instead of a single 18650.
Would this be possible with the Zanflare T1?
Or would that release the “magic smoke”? I am a bit reluctant to try, because the user manual only mentions the use of a single 18650…
At least I can confirm that the reverse polarity protection works correctly in the Zanflare T1, just discovered by accident 
If the lantern can handle the 5V from the USB, I would guess the 6V of the 2xCR123A’s would not be to far off, especially if Zanflare built in some tolerance to deal with non-standard USB power banks providing too much voltage? Or is there something I am missing.
I doubt the 5V USB input gets passed “as is” to the light. It is most likely down converted to lower voltage.
EDIT: Just checked. When powered via USB port, internal voltage is 4.22V when off and drops to 3.57V when running at max brightness.
Not too fast, just linear vs logarithmic.
People were beeyotchin’ about the RJ02 doing that, ie, a linear ramp vs logarithmic, so even though the increase is linear, the bottom/dim end of the scale zips right on by, vs the top/bright end of the scale where it just draaaaaags.
So 5–25 (20, 5:1 ratio) goes by in the same amount of time as 80–100% (also 20%, but only a 1.25:1 ratio). Former is dramatic, latter is hardly noticeable.
I grabbed a ZanFlare T1 to test, which arrived a few days ago.
The included battery “BFN 2600mAh” tests 2720mAh (charge to 4.20v, drain to 2.50v cut-off voltage @ 0.50A discharge rate, using MC3000), IR test ~ 55mOhms.
Haven’t had time to do a full charging test of the built-in micro-USB port, but I did a quick charging test of a VTC4 I have here (it was around 4.00v when I inserted in the ZanFlare T1 to do the charging test):
(max charging current is probably 1.0A, but since the battery is nearer full, the charge current quickly drops to around 0.6A (USB current) and declines until around 0.14A ending USB current)
Immediately removing the battery when the charging indicator became full, tested to be 4.145v on my DMM (quite similar to Pete7874’s result).
I notice there the USB still has around 0.01A current when finish charging (but it could be power consumption of the “light indicator” LED on the lamp?)
demo of changing color temperature for ZanFlare T1 lantern:
The quick double-tap to change color temperature seems to need a bit of getting used to get it right.
I do have a complaint for the tailspring used — it doesn’t seem to be that good quality, and mine has the plating/coating come off already when it arrived (looks tarnish/rusty).
Thanks for pointing this out. Mine seems to have the same issue.
i run s*tload of tests, will post review in 2-3 days.
with coupon it is a good deal
without…i dont know, still considerable
WW is 2 times less bright than CW
no stabilisation
The plating on mine is perfect.
Did a full charging test of the ZanFlare T1’s micro-USB port charging behavior:
(first drained the included “BFN 2600mAh 18650” — I tested 2.63v after draining the battery, then placed in the ZanFlare T1 lantern and started charging)
It appears to charge at max 1.0A, with ending USB current at 0.14A (USB current). After I removed the battery immediately when it became fully charged, the battery tested 4.14v on my DMM.
So far the samples seem consistent so that’s good
While not as severe as d_t_a’s example, my tailspring is also slightly flakey.
Just observed the colour temp ramping is ‘jumpy’ on USB power, it ramps a little then jumps before ramping a bit more, has anyone else observed this?
Same here, there’s a jump on color temp ramping, when completely powered by the micro-USB port.
Last night I observed some strange behaviour of my T1. About 20 minutes or so after I had turned it off from the lowest output, the lantern started to slowly flicker with some really low firefly output. I only noticed this because my sleeping room was pitch black.
After I turned on the light and then shut it off again, after 5-10 minutes the light began to “glow” again like some glow in the dark material with varying intensity. Kind of spooky, so I removed the 18650 from the lantern.
Anyone else has seen this happen with their T1s? To me, it seems the possible cause for such behavior might be a power leak somewhere in the circuitry.
Edit: The light had been on max output for a few hours before switching it off.
I haven’t noticed it, but I’ll check it out tonight in a pitch black room.
“Mr Sandman” is keeper of the luminous flux. Guess you pissed him off switching back and forth like that. You were supposed to be sleeping before he brought you your “dreams”. :weary:
No complexion of “peaches and cream” for you. : 
:innocent: Seriously, could be some high glow phosphors scattered about in the flux for all we know. Same thing observed in some TV screens also.
I have not been able to reproduce the erratic behaviour. The problem with things that go away by themselves is that they also can come back by themselves.
Got my lantern today and really like it. Anyone think the no name battery is worth keeping or just too risky to have around?
Just my opinion of course.
Glad I'm not the only one ready to dump the battery thanks!
