Why is this not a thing?
Think regular mechanical mod, but like the Atto and a couple of others, mosfet board in the top.

Unlike the others, equip this with PWM to adjust duty cycle

Simple adjustment, adjust duty cycle with the top cap or a little ring at the top

compact, rugged, awesome, effectively a VV mod. You could use it like a mechanical, and just coil for flat battery...

why not a thing?

You mean like an Ego twist, but modern, and 22/24mm diameter? Well, it would need a boost chip in order to be nothing more than a mosfet with a step-down dial...it couldn't ever do more than the battery voltage without a boost chip.

This is possible, of course, just not too "practical", in that the requirements basically mean you have a regulated mod, and they sell much better. If you're gonna stick a boost chip in, might as well add regulation, you know? At least, that's how most Companies would probably feel in today's market.

The closest thing are regulated tube mods. Tesla, EhPro, and Uwell make modern versions, and some probably have bypass mode. That's probably about it, besides finding old gear in a shop, maybe.

For small mosfets, I just received the BP Hilt, a DNA-less brother to the Iaido, and it's a well made, cheap, tiny little thing -- that also can use 350s, if desired. Nice little mod.

Ah, I get you...well, I guess you know why that's not a thing...most vapers don't want or need a step down from 4 volts, as the battery will do that by itself as it depletes. there are a good amount of these mods for thc cartomizers, but I haven't seen many for over 14mm...many will have 3 or 4 settings, UNDER 4 volts.

Maybe you'll get lucky...

For most people, VW are the most easy solution,
because they e.g. perhaps use different coil resistances.
But for always the same coil resistance and same watts,
which some users use, constant Volt is sufficient.
That means, for some users a small tube mod
with just a constant output of about 3.7V (18650)
would be a very good solution, because simple and small.
Yes, a Pico can do the same, but a tube mod is more stylish
special for very low drippers.
The best solution would be an Atto with constant e.g. 3.7V output.

Edit: to make it more simple, I changed VV to constant output.

The thing is - if someone did actually manufacture it, how many people would actually buy it?

It seems to me a regulated tube with VW and a boost chip would have more appeal.

Yes, today some people like the more easy things, and not the last high technical evolution.
That make live less complicated.
Such a tube mod would be very small and stylish if you like small drippers.
A lot of users like small drippers, they also make life much more easy.
VW or VV would make the mod too big because you need a button or wheel for that.
I am not an electric specialist, but yes, this thing has to boot 3.4 to 3.7 and decrease 4.1 to 3.7.

Edit: And depending to the resistance of your coil you get 10 to 60 watts at constant 3.7V.
The vaping time with one battery will increase a lot because you use the battery from 3.4 to 4.1 total with full and same power to the coil.
(just an add for the vaping starters )

But VW isn't the latest hi tech evolution - its been around for years and commonplace. A small firing button on the side doesn't add any more bulk than a mechanical switch on the bottom or cramming electronics and a firing button between the firing button and the 510 - and it gives a consistent vape for the entire battery charge without having the inconvenience of having to build to a narrow ohm range.

The reason there aren't any simple small tubes with kick down to 3.7V is there isn't enough demand to make them commercially viable.

@ Crispycritters

People using an Atto have to build their coil exactly to the ohms to get the desired watts.
The Atto is/was an unregulated tube mod, and the users have to live with volts 3.4 to 4.1, not a constant vape and a lot of battery change.

With the addition of a constant volt component to the existing chip,
we would have constant 3.7 volts resulting in constant vape and a much longer
battery using time in the mod, because battery 3.4 (3.3) to 4.1 can be used.
With such a perhaps small and perhaps very cheap construction change,
an Atto can improve a lot.
Sure you will have to build the coil exactly to the desired watts,
but thats the same on the original mod.

And tube mods sometimes have beautiful designs, collectors items.

VW or VV will only be a help for users which want every week a completely
new and different coil construction, and VW/VV needs construction space.

I do understand what you are talking about, but the demand isn't there.

I'm sure there are a handful of people that still use exactly the same build and vape at the same voltage as they have for years. But they are a minority - as hobbyist vapers are only a small percentage of all vapers, they are a minority of a minority so it makes little commercial sense to make products for them.

Your best chances of finding the type of device you are looking for is to join a few Vape Forums (NOT Fasttech where the majority of members just come here to squabble and ridicule each other) and start a Wanted style thread as there normally members who have vaped for years who have plenty of old equipment they no longer use.

Good luck.
