VW Question

[CharleyDanger]

So I am waiting on my VW device, but I am confused about how it works...

I have seen people vaping a VW device at 25 watts with a 1.6 single coil build. If I put those numbers in the ohms law calculator it looks like....


Volts -
Current -
Ohms - 1.6
Watts - 25

Result

Volts - 6.3
Current - 3.9
Ohms - 1.6
Watts - 25

So the device uses a dna 40 with parallel 4.2V 18650s 30A....

The amps are at a safe level, but the volts are too high at 6.3 on a 4.2 battery. How does this work? I thought parallel batteries double the amps and mah, but the volts stay at 4.2. Does a VW device some how use more amps and lower volts? Is that even possible?

Regulated VW devices do just that: regulate the power output by increasing the voltage (to the devices amp limit) to match the requested wattage.

think of the VV/VW mod as a variable transformer... it raises/lowers the voltage within a set parameter by design.... on avg most go from 3.2 to 8 v

a good example would be a dimmer switch for a light bulb.....

You may find that the only thing you will need to consider is what setting works best for what ever tank and juice you use. Once you find that "sweet spot" voltage or wattage, the need to understand or be concerned with the VV/VW goes away.

Most regulated devices have what's called "boost and buck" circuitry. That means it will boost the battery limit higher or buck it lower. It allows you to put in a freshly charged 4.2v battery in your device and vape at 6.4v or 3.7v. (or whatever volts are required to produce the watts you set it for in VW mode).

I swear I'm not stalking you.

The chip (in your vv/vw mod) takes in power from the battery and stores it in a capacitor. When the stored energy reaches the potential (voltage) it dumps out to the atty.

lol, I appreciate the feedback. I have been surprised how cool the vape community has been. Not usually the case in online forums lol.

That is awesome. I wonder what it was like being a vaper 5 years ago lol.

With regulated, don't worry the math so much, just crank it up till it's not so good, then dial it back till it's just right. That's the beauty of regulated mods, even if ya ain't got the best build, tank, changeable, wick, whatever, you can still dial it in to it's peak purrformance. Then once skills are attained and knowledge expanded, then one can dial it in some more

Sweet Spot??? I view sweet spot more as a skill spot, in other words, dial it in to the best you can get for what ya got. but seriously, finally found my sweet spot at 50-75 watts, with flurries into the low on 100's and an occasional dip into the mid 40's




Vape long and Prosper.!!!!!

I'm coming up on 9 years vaping. Back then we had nothing to compare it to so we didn't know how much better it could get.

Needless to say, I'm "one happy camper" these days!

you got part of it right.... dont forget the inductors... between the 2 of them working together it raises the voltage higher than what the battery is capable of..

my avitar pic is a fine example of how one takes a lower voltage and increases it to a higher voltag using inductors ( coils) and capacitors... and btw the "lighting bolts" in the pic are 10' long

Then you would have had to learn about Fluval aquarium filter foam and teabags.

There must be a huge variation based on the build and personal preference. I build my kayfun to about 1.6 ohms, and vape it at 11.5 watts, it equals out to about ~4.2 volts. But that's just me, I like a nice cool vape, anything more is just a touch too warm.
