VV Devices

[Bluefish]

How do they work, what do they do? if a standard e cig is 3v ish, then you have something that goes up to 6v, obviously they use more power at a higher voltage, and i take it the higher the volts the more vapour produced, more juice used? this warms the vapour up more and you set the volts to your desired taste. But then you have Lower ohm's ie 1.5 or 2 ohm tanks carts, what do they do, or what's the effect of them/differance between a standard 3 ohm cart? then lastly, for now, dual coil tanks etc, same again, iassume two coils twice as much heat, juice used and vapour produced, I get that with them you have to turn the voltage down, can some one explain to a thicky, cheers andy.

[Karma]

Explain what? I think you just explained it to me

I'm sure someone will be along shortly to help out with more technical details

LOL

Variable Voltage devices will give you a regulated power output, until your battery has emptied it's charge, so you don't get drop offs in performance . . . it's consistent from start to finish.

Plus, you have the adavantage of being able to use any resistance atomiser/cartomiser on a VV to enable you to achieve the vape that's good for you.

VW or Variable Wattage devices . . . like the Darwin or the Kick, are a little different, in as much as you set the wattage then whatever you attach, will perform to the watts/volts it's set at . . . so you don't have to adjust anything.

Although, a 3.7v mod, with a Low Resistance whatever will give a very good vape . . . until the battery starts to run down.

I'm not a techie Blue . . . so that's my very non-techie way of explaining it to you.

Variable voltage devices give you a control over the voltage sent to the atomising coil ...as you say more voltage the coil will heat higher and quicker and burn off more juice... changing the flavour, creating more vapour and often warmer greater throat hit.

now atomising coils also come in differing resistances anything from from around 1.5 ohms to 3ohms... the lower the resistance the more current can travel through the coil and so it'll heat up hotter and quicker burning off more juice and give you a different flavour, vapour and throat hit to a higher resistance coil.

dual coils are slightly different as they have two coils but a 1.5ohm dual coil carto is actually made up of two 3.0ohm coils.... so with these they wont heat the liquid up to as high as a regular 1.5ohm carto but will burn off twice as much due to having two coils

[Gordy]

what it all boils down to is Wattage

Watts = Voltage² / Resistance

say you use a 3.2volt ego with a 2ohm carto
3.2² / 2 = watts
so you have 5.12watts

so you can get the same vaping experience from a 3.0ohm on a VV device... to work out what voltage, you do the sums

Watts = Volts² / Resistance
5.12 = Volts² / 3.0
which is the same as 5.12 x 3.0 = Volts²
= square route of 15.36 = 3.9 volts

[Gordy]

now i like vaping at around 9 watts and usually use 2ohm cartos at 4.2 volts
i also know from trial and error that if i direct drip on a 1.5ohm atty i have to drop the volts down to 3.6 volts

so i could do the sums each time or up and down the voltage until i find somewhere that tastes right but there is a device called the kick that does the sums and adjusts its voltage accordingly to how many watts i have it set at

ok so i know too much info but well i got carried away LOL hope it helped clear up a few things Blue

[Bluefish]

Thanks peeps, much clearer now. so what options have i with my ego t 900mah batts, I could get one of the vv batts, i believe you can't use lower than 3 ohm tanks? Just want a bit more hit and vapour, seriously considdering the vv batt, but is there any thing else i could use, thanks for explaining this, no doubt for the hundreadth time lol.

[maccafan]

You can use any ohm with any VV device..Just make sure that the Voltage on the device is set corresponding to the resistance. I use a 2.2 ohm stardust with my 3 step VV battery set to 4.2 volts. Under load it gives me about 4 volts when fully charged. But it's a personal choice..

There is a product called ego booster that'll work with your ego-t but it's prohibitively expensive and not worth it. So use 2 ohm or 1.8 ohm carts with your ego-T if you need a more powerful vape.

I've had my Riva 1100 for about 6 months now and it's still going strong for now, but I'm looking to get a VV as a replacement. I have about 20+ Kanger LR carto's (510 threads) which are perfect for me and was looking for a VV device which would suit them....any ideas?

[maccafan]

If you want a Ego/RIVA style device the forthcoming ego twist looks most promising..



Worth waiting. Should hit the market in a month or two. You can get a 3 stage VV device which I have been using but it's not much different from the RIVA in terms of performance though it does allow you to step down should you wish to do so: Might be useful for LR cartos that you have.

Dissie code hut10 for 10% off.

Otherwise it's bigger battery mod territory and you can start off with a Lava Tube:

Dissie code thankyou for 10% off.

If you got a 18650 batteries and chargers you can buy just the body and try.

You can put any 510 atty/carto on any 510 connection.

The results are in question lol

They can very from the best vape of your life, this normally equates to having found your wattage sweet spot, absolutely insipid that corresponds to a 3 ohm cardo/atty on an Ego that is normally putting out 3.2 volts, to burnt taste and blown atty that corresponds to a LR atty/cardo of 1.5 to 2.0 ohm on a variable voltage device set at 5+ volts.

LavaTubes, ProVari's have safety features to prevent the last scenario most low end variable voltage devices do not.

Keep that in mind and you will be good. Any idea how many yuk's it took me to learn that on my Ego then first VV device ?

[Bluefish]

maccafan, that vv batt look's very promising will defo get one of thos asap, must admit my ego's working brill tonight loads of vapour
