why do people build super low ohm on a vv or vw device?

[justinlm24]

I use vw devices and like my builds from .2 up to about .5 ohms. My two go to devices are my sx mini and my ipv mini. 60w and 70w max capacity. So I cant just throw a high ohm buil on and crank it up. I do not get an enjoyable vape for me at 60 watts with a 1 ohm build. Therefore I build low and adjust my wattage accordingly to how I enjoy it. One of the perks of buying a vw device in the first place. So does it really matter why people vape the way they do as long as they enjoy it? I don't believe so.

Bravo. Agreed here. .5 ohm and around 22 watts gives me MUCH more satisfaction than an 2 or 3 ohm and 10
watts. Since I started sub ohming I don't chain vape and have cut my nic down to 3mg. Tootle puffing just doesn't do it for me anymore.

That's totally up to the builder of the mod. (how much are you willing to pay)
I have plenty of "regulated devices" that won't even fire anything below one ohm.

It is true. You can't deny Ohms Law. Steam Engine has a calculator with specific presets for all of the popular regulated mods.
You can pick something like, for example, the Sigelei 150 and see that this mod requires builds between 0.167 – 0.375 in order to achieve the full output advertised.
Or, for another example, an IPV4 requires 0.1 – 0.49 ohm builds in order to reach to advertised wattage for that mod.

It works for any high power regulated mod. Try it. Mod range | Steam Engine | free vaping calculators

I ask this question because I've read so many threads on super low builds on vw devices and I don't get why people do it.
obviously I can understand it on a mech but on vw why not build a higher ohm coil and just turn up the wattage to get what you need.
isn't that the point of vw mods?

Have you ever seen a 1.5ohm nickel coil?

 

[LobsterGoD]

most of those high wattage devices need the lower resistance to hit their max setting, i.e the raptor 40a boards have to have at least a .3 to hit their full 200w as do several of the chinese boards.

This discussion is about high powered devices.

I do think that many newer vapers have been led to believe that very low resistance combined with very high power is the only way to get a good vape, so they just follow along. If you look at the powerful starter setups often recommended here and at vape shops, one would think they need that combination and anything "less" is not worthwhile.

Manufacturers and resellers, driven to sell more equipment, have cut down or discontinued many of the higher resistance options. The atmosphere in vaping has become more power, less resistance in an endless pursuit. Very profitable indeed for resellers of equipment and liquid.

The market is there.

Hardware and juice manufacturers are typically not the same.

i doubt there is a conspiracy between them.

I tend to favour low resistance builds generally because I like warm vapor. It seems to be a big factor is me feeling satisfied.

 

[noel18]

Agree with sonicbomb. Low resistance builds are necessary for those seeking really warm vapes. I understand the term 'really warm' is subject to interpretation.

AND, that "need" is created by the person that designed the board. If people's wants were different, they would design the boards differently.

It is not that simple.

There are current and voltage and component and size limitations to overcome.

Otherwise every device on the market would go from 2 volts to 20 volts with no current limitations.

I am about to buy my first regulated mod, leaning towards the Sig 150. I have been using a mech for close to 9 months now. What I have learned is that larger surface area = bigger clouds = shorter time between charges. If I use Kanthal, my coils take about a day and a half to heat up and my batteries die quickly. Nichrome heats up super fast, is easier on my batteries, and with the proper airflow, doesn't overheat and make my juice taste burnt, but safety becomes an issue below .5ohms. I want to try the regulated mod so that I can play with the different options and find a sweet spot. I'm not saying everyone should follow me off the cliff, but I want to jump to see how it works for me. It's all about personal preference. There are so many options out there that everybody can choose their own fave and roll with it.

yes your right but does anyone vape at 150 watts on a regular basis.
I tried to vape a friends device at 90w and my throat thought I was vaping molten lava so god knows what 150w is like

This was my "office", 1960s. Today, all that (and more) is contained in a hand held unit.

Do you have any idea of the wattage that MRC-108 was capable of producing from an old 12v lead acid battery?
That was 50 years ago!

With current vaping battery technology, it could be done (150 watt with 1 ohm resistance) if using four 18650 batteries in series.

I have a 2" cubed box that measures pulses, frequencies and outputs 180 amps at 7.4 volts to a motor and controls several functions on one of my toys.

Half of that space is a fan and a heat sink.

I get it. I really do.

But to put accurate, reliable buck/boost technology outputting that much power into something the size of a prothingy with space for a (at least 2 at the current outputs available) battery (ies) is going to take a .... load of engineering before code is written to control it.

That's why it hasn't been done yet. You're comparing technology that's been constantly improved upon for eons to something we just recently hit the 20 watt mark on within the last year.

Not to mention, who in their right mind is going to carry around a lead acid battery to replace cigarettes?

If you're going to compare apples, your basket should at least contain fruit of some sort.

My point is that the manufacturers produce what we want, and it really has nothing to do with what can be done.

How much liquid is vaporized in a given timespan - surface in contact with the liquid, temperature of that surface, liquid flow depending on wicking material and liquid viscosity...
That what it vapes down to.
Power, not the problem. Making it portable is.

Still remember the first portable personal computers ? Monochrome screen with the size of today's smartphones ? Lugging them around saved you the monthly subscription fees for the gym...

Transformer, plugged into a wall socket, protective circuitry, u can go as high as the main fuse of your dwellings will allow before popping ... and that a lot ... like 30 Amps at 110 V

The feat is in delivering that oomph in something that fits a purse or a pocket...

I've never done it but if done right, it's probably not bad. Using thicker wire, you aren't going to be hitting hot temperatures since its about using more power to ramp up a much larger surface area.
