I searched and couldn't find much info on this puppy at all. Must be pretty new on the market. I know there are a couple of other high power regulated mods on the drawing board too, but can't find where I saw those now.

I hope this works out. Think it will be very good for high power, currently known as sub-ohm, vaping.

Anyone know more about it?

"do not overturn the potentiometer" "Do not run this mod above its specifications" not exactly packed with safety features to keep it from stressing the batteries.
I dont think it's wise to rate the mod at 100% of the battery current draw like that but im sure someone will buy it and slap some 30 amp-ers in there.

In the blog under updates the creator himself uses a DNA 20, not exactly a confidence builder when the guy making them uses something else......... just sayin :)

Series batteries and a buck regulator (with built in current limiting, short protection, and thermal shutdown)...Output current will always be higher than the battery drain current.

Thanks for the info Rader! I have the OKR-T/10 datasheet but didn't work through it yet. I did notice 600 KHz pulse frequency and the safety features you mentioned. I also wondered about the comment on the website about running the mod above its specifications as Thrasher mentioned. If the board is current limiting, will it burn out if you hit the limit too often? If so, how serious is it? I'm thinking pulsing out shorts, not running too low ohms for the power setting.

At 50 watts I'd probably go in cardiac arrest on a full lung inhale ...

LOL, I hear ya tc1 and agree. I never do lung inhales anyway. Tried it a few times for ....s and giggles, but I never smoked that way and I found it mutes flavor. And the extra vapor doesn't do much for me. Never felt the desire to go over 30 watts and I'm perfectly happy at 20. Having a regulated, protected mod that is happy at 50 watts and using it at half power sounds very good to me.

Couple key notes from the datasheet:

-Output Current Current-limited. Devices can withstand sustained short circuit without damage.



-(6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected setting.

This would tell me that all the short protection is done by the controller with the current sense and voltage reference as triggers. Response time is going to be uber-quick so you may have a hard time pulsing out shorts if they are bad enough to trigger the short protection. I wouldn't worry about damaging the regulator, it's designed to save itself. Heat generated in a short condition is what usually kills a chip, and this is designed to prevent that by with the short protection AND the thermal shutdown.

Got it, makes sense to me and I appreciate your input Rader. It's going to be very interesting to see where this goes :thumb:

I would go read the notes from the builder, I gather this is more of a side project and wouldn't count on mass production anytime soon' building 10 or 15 at a time sounds more like a hobby.

I agree with you Thrasher. I'm not going to be buying one of these tomorrow. But I suspect this is the future of what is now sub-ohm vaping. And I'm not one to jump on any bandwagons just because it's something new.

Time will tell and I'm good with that. Hopefully the politicians will let it go that far.

What i do like is cruising the posts lately is the abundance of choices recently, many mods are coming or in development and thats a good thing. there's a 40 watt floating around as well, such a far cry from the old 808 or silver bullet days. and the govment can try all they want, ill just go to the flea market and buy mods and stuff from the booth next to the guy selling ...uhhhh........ the water pipes that are supposedly banned years ago


Hopefully the politicians will let it go that far
they can screw with blu and njoy all they want, but really whats going to stop modders from selling on side markets, low key forums and flea markets lol

I have one of these devices. It's not perfect, but I love it. I ran it at about 45 watts just for kicks. It's a little much. I'm hovering between 30-40 now. Nothing I've used so far does what this thing does.

Nice! Can you give us a bit more about its good and bad points? Also, does it look/feel solidly built?

50 watts!!!!!!!!!!!!!!!!! are you nuts. No way no how.

LOL, tnt, I'm not looking to vape at 50 watts. I could vape at 90 watts with my Sony 30A batteries in the K100, but I don't go over 30 (with a fresh battery).

What interests me is the ability to vape at 20 - 25 watts with a regulated device so I lose the power drop-off as batteries discharge in a mechanical mod. Plus the safety features on the board. Plus the ability to pulse out shorts in my AGA-T with the same safe device.

All good in my book :thumb:
