If that is the body connected to the head, then it's probably not a standard single 18650-sized light. Seems too big in diameter. Just speculation...

usb charging?
i think we had that already. Klarus, Nitecore for example.

I agree, maybe 26650 or a multi 18650?

If you're looking for novelty, I had a Nokia rechargeable light in my pocket like that in 2005. It could also play Snake and make phone calls.

A programmable flashlight maybe?
Now that would be awesome!

The fins and knurling placement make it look like a maelstrom model. Whaddyall think?

Nice to see Foursevens working on a USB charging flashlight. Nitecore has a few but doesn't have the most updated emitters in them. If they make this light, I hope it has a high binned Cree XM-L2. I'd prefer a single 18650 putting out as close to 1,000 lumens as possible on high with settings down into the sublumen range running for months. If they really want to corner the market on USB lights, make a little tailcap extension that turns their Quark lights into USB rechargeable lights and make that section also screw into the regular tailcap. If you can make it this way, you can avoid compromising the waterproofness of the light, protect the charging circuit, and it might be possible to keep it in that configuration while the light is in use. It would just add a little length to the light, hopefully no more than the length of a 123A cell. If you can pull this off, you can make most of the flashlights (not the preons) rechargeable and have the charging circuit be an easily replaceable part for when the contacts fail (and they do).

Not electrically possible. To charge correctly, the charger needs access to the (+) and (-) ends of the battery. It also needs the light to not turn on and draw current. With the Quark buck/boost setups, you aren't going to have dangerous voltage input to the light, but it will throw off your smart charger.
However, it would be JUST possible to make a film-wide (Very thin) sleeve the battery goes in, with some kind of electrical switch to isolate the head of the light from the battery during charging... Not easy. And the size of a mechanical switch in a Quark-sized tailcap is difficult, but since you have one electronic switch you may as well have two...

try nextorch's mytorch usb programmable lights.
Thanks for the tip, a quick google took me to Selfbuilt's review. With minimum 5% low and using PWM it's a no go. 47s always seems to consistently have the best, and most accurately spec'd, moonlight modes for my uses and tends to like current control - I'll stick with them. (I've now been disappointed with 3 out of 3 recent moonlight mode purchases from other reputable manufacturers, and I test with a light meter.)
i think this May be a sneak peak of the blue tooth light 4sevens has been planing. Pair it with your phone, change modes and program the light from your phone. And if the light gets separated from you it will flash and produce a high pitch noise so you can find it. Kind of a neat idea, I'd be willing to try one out but I don't know how popular this one will be. Again, I'm not certain that the light in the pic is this particular one but I've kinda been anticipating it so I hope it is for my sake lol

It's 18650
The picture is zoomed in so it looks bigger than it really is. It's extremely compact for an 18650 light.

You are killing me. Hurry up and sell me some new lights!
That sounds like it has the potential to be really annoying lol.
Oh, THERE'S my flashlight lol.

troll post. not funny. where's the downvote button?
it's gonna be a proximity alarm flashlight. extremely useful to those who need them. totally useless to those who don't

On second thought, it might be more doable if the Mini-USB charging section is between the head and the battery tube. This way you can remove the head during charging to plug the rest of the light into a power source. All that would be required would be to turn on the tailcap switch to make contact between the positive and negative terminals via the normal electrical path of the body of the light. The difficulty would come in how to connect the charging section to the head of the light while maintaining all modes. This can be done in a few ways: 1. Have the Mini-USB port come out the side of the section. This eliminates any issues with maintaining modes but will likely cause a reduction in water resistance. However, as the section is removeable and only needed during charging, you have the option of only having it on the light when necessary (an option not available for other USB charging flashlights.) 2. Have a similar setup to a USB cell. This would technically maintain all modes, however it may cause resistance or a sort of bottleneck for power that may limit higher modes (depending on how it is implemented). 3. Offset the USB port to the side of the top positive electrical contact to leave room for both on the same top inside of the light. This will be difficult to manage the space issue, but if it can be done, it will eliminate the waterproofness problem and the electrical resistance problem of the other two options. The only other things to worry about are how to prevent the power for charging from going to the l.e.d. instead of the batteries with the side USB port option (option 1), and how to prevent power going to the l.e.d. from being diverted to the U.S.B. port. In both cases, this would most likely involve some sort of switch. The easiest way would be to have something that gets pushed in with the U.S.B. tip to activate a switch. When you remove the tip, power would be switched from going to the U.S.B. port to the normal electrical path to the l.e.d. thus avoiding any external switch that would compromise the waterproofness of the light.
The cheapest and easiest way to have a charging setup would be to make an endcap on the positive side that doesn't screw onto the head, with a side Mini-U.S.B. port and simple connections in the endcap using the sides as the negative terminal and a center spot as the positive terminal (same as the head of the light. With this setup, there is no need for a second switch, no worry about power going where it shouldn't, and more room to work with. This setup would not require or allow the head to be connected during charging. You could sell this as an accessory for field charging for $20 or so and have the fewest technical headaches to deal with.
