Emitter shown in second link. Can anyone tell me what this is? 65lm luxeon? Same emitter/optics seems to be used in the next two


[edit] - This form factor looks very nice, expensive though [Cylinder-aluminum-alloy-mobile-power](http://www.anrdoezrs.net/click-7121496-10887173?url=http://www.aliexpress.com/item/Cylinder-aluminum-alloy-mobile-power-1-day-18650-mobile-battery-Q5-the-strong-light-flashlight-suit/735562056.html&cjsku=542478748)

Now, this is the ultimate drop in form factor This is what caught my eye and started me digging… it’s been around for a while, and wondering if people have played with it? Apparently it has a metal head.
Mention of a SSC P4 swap in this thread: http://club.dx.com/forums/forums.dx/threadid.232881


[edit:] Similar chargers have started showing on ebay (with a cree emitter?) http://www.ebay.com/sch/i.html?\_ipg=50&\_stpos=&\_fcid=104&gbr=1&\_localstpos=&LH_IncludeSIF=1&\_dmd=1&\_mPrRngCbx=1&\_ds=1&\_nkw=cree%20power%20bank&LH_AvailTo=104&\_sop=15
What I would like to know is, which torch would be more moddable, as I am ordering this
- Loyee 3000mAh Power Bank with LED Flashlight [edit: most likely not a loose cell charger :/]

Well, maybe I’ll get both when DX has it back in stock, and have a Darth Maul light saber;

Thoughts, if any, on swapping the emitter/optics? In particular I would be interested in swapping in a high power red :open_mouth:

This one is nice from Fasttech - lights up a room well.
https://www.fasttech.com/products/1280704

haha that looks amazing

what emitters are those?

That one looks nice. I got a few laughs out of your comments in the ‘Metal?’ discussion thread. For example:

:smiley:

No idea, some sort of generic led…. but there are 18 of them, so it puts out a fair bit of light.

That one at everbuying comes with a 2600 cell! :bigsmile:

Marc.

That one is pretty neat.

I quite like the look of this Kmashi because it’s a nice size and pink. Not sure how good the light is though. >.<

Someone on here had something similar to that KMASHI and it ended up melting down due to an internal short. I think it was from Fasttech and they pulled the listing. There’s a thread somewhere.
That doesn’t reflect on this one at all (unless they were the same brand), but I have concerns over how compact it is with an unknown18650 cell inside it.
I would like to have something like this (in black) with a replaceable cell. I currently use a ML-102 which works well, but when charging from it ‘on the run’, I keep thinking the cell is going to fall out.

I own the first one (3x18650 xml), and it is quite moddable. It has some reasonable throw, it is driven by the batteries in parallel, using a 17mm 8x7135 driver, the brass pill screws into a massive chunk of aluminium. So far the good news, sounds like just update the led and put in a massive driver and blast away. But the bad news is that there aren't any real fins to let that heat leave the body, but also that I do not trust that small switch to deal with more than the 2.8A the light comes with.

So the only mod I have done yet was changing the led to a warm white I had lying around. It is too big to my taste for a 600 otf lumen light. But I am very happy with it as a backup charger for my smartphone, I get 4 complete charges out of the 3 2250mAh pana's I put in it.

I wonder how you could check for something like this :open_mouth:

djozz:
2.8A is pretty nice :slight_smile: So you modded the pill it came with? Do you know if you can buy ones which fit anywhere?

Updated the first post with some other threads I came across :slight_smile:

I have two USB charger boxes. The output of the first connects to the charge input of the second. And the output of the second connects to the charge input of the first. It’s been running that way for ages. I now have infinite power available! :wink:

Could you imagine the kind of power you would have if you had 3 of them! :bigsmile:

Marc.

bingo! found some usb connector led modules at sunsky!

also from xtar:

[edit:] some more, first dx one looks quite moddable

i’m in modular heaven :bigsmile:

hmm after inquiring about one of the generic tube chargers, one seller claimed that the battery wasn’t replaceable. Sounded crazy to me, so I looked for a review and saw for some models it’s true

Modding these sorts of USB chargers is apparently simple enough, but requires soldering the battery. This applies to the above Kmashi also >.<

If anyone knows of more models like these which can accept drop in 18650 cells like relic requested, please post!

Reviews say it charges 18650, spring contact often needs fixing though
http://www.buyincoins.com/new_en/details/portable-18650-battery-emergency-charger-micro-usb-adapter-for-iphone-4-4s-product-18352.html

[edit] Solid, but a bit big and no retailer

i’ve ordered two of the gold charger linked above
http://www.buyincoins.com/new_en/details/portable-18650-battery-emergency-charger-micro-usb-adapter-for-iphone-4-4s-product-18352.html

they both behave exactly the same way, i can’t get either to work and am completely stumped :confused:

the case seems to make contact with the (protected button top) battery ok, but none of my usb devices will power and i measure 0.40V and less than 1mA from the output. if anyone has seen similar behaviour from a usb charger i would appreciate the input


[edit:]
there are a few comments in russian on the bic site about contact issues and missing solder bridges, but i don’t know how to get the front cap off to see :confused:
the case is exactly the same as the dx review linked above (http://club.dx.com/forums/forums.dx/threadid.1287248), but with a battery contact board at the front, deanodised case end and spring at the back. however the front cap unfortunately appears to be glued

i ordered a black one, and they possibly checked their batch… this one works, with short cells at least!

long protected cells like TF flames will cause issues as it protrudes beyond the charger body, it won’t screw in all the way but with some careful modification a connection can be made. to do this ideally a metal spacer ring should be used, because otherwise the tail spring can wrap around the the battery and rip the plastic, shorting the protection circuit strip at the same time.

also, the end of the front positive spring is not safely bent inwards, so if a long cell is twisted against it tightly it can lock into the button ventilation hole and can twist and deform, possibly shorting with the negative tab. if one could only open the front cap this could be fixed of course…

the case itself has no ventilation, so it really needs some care.

it has no switch to turn off the parasitic drain unfortunately, and neither do the sunsky usb led heads – but you can untighten the tail cap.

so, a tentative new usb drop in host for me =D wish the sunsky heads were a bit smaller though - 28mm vs 22mm

Glad you got one that is working! Where did you get the black one from?

ebay, but it ended up being the same buyincoins :confused:
this is a convenient, compact 18650 charger + usb power bank chloe, the type of item i was searching for to give to friends

unfortunately the tail cap modification for protected cells is an issue however!

i edited the first post with some other choices, including these on ebay recently

they are a lot bigger and expensive than the bic one however

the list of excuses is shrinking not to grab some 18650s i think :smiley:

For one cell it would be handy to have I think! But any QC issues really puts me off.
