Hi All,
A week ago I picked up a Redds starter kit after smoking a PAD for over 20 years and not only have not craved an analog, but am repulsed by the idea of having one. Can it really be this easy? I guess time will tell. A big thanks to everyone on this awesome site.
Although I'm very happy with the Redds and plan to continue using them for social/outdoor situations, I'm already getting the urge to upgrade for work and home. (Trading one severe addiction for another? Lol). After a lot of reading I have decided to pick up a couple 1000mah ego twists and vivi novas, but have a few questions.
1. I know it's very subjective, but is there a general consensus on what resistance works best with the twist? 9 watts seems to be the preferred level, so that puts the 2.8 ohm slightly out of spec. Would like to pick up a pack of 1.8 or 2.4 atty's until I can locate some Kanthal wire. I'm using a 70pg/30vg blend at present, but hope to try a 70vg/30pg blend in the future.
2. What is the difference between the 2.0 and 2.5 Vivi Novas?
3. Someone mentioned getting two chargers. Is this really necessary due to poor quality or was the poster just being paranoid?
thanks,
Trevor.
See if this does anything for you.
From a previous post of mine:
[Simpler version: turn the knob to higher volts for a warmer vape, lower volts for a cooler vape, or to compensate for variation between "stated" resistance and "actual" resistance of a coil].
This can all be demonstrated by a very simple formula that related "Ohm's Law":
Volts time volts divided by resistance (rated in "ohms") = watts (heat) at/in the coil.
Vaping at 4 volts with a 2.0 ohm coil would give 8 watts; 4 x 4 / 2 = 8.
Consider the three heads in the Vivi Nova; 1.8, 2.4, and 2.8 ohms:
With a Joyetech eGo-C Twist, or any other variable voltage device, you can achieve any wattage you need to get a good vape, even if the "actual" resistance of the "heads" varies from the "nominal" resistance of the heads, which it almost always does.
I'd say that most people vape at between 4 and 8 watts per coil. Notice how 6 watts can be produced with a Joyetech eGo-C Twist (or any other variable voltage device) with any of those three atomizer heads. This obviously can't be done with a constant-voltage battery.
3.28 volts x 3.28 volts / 1.8 ohms = 6 watts
3.79 volts x 3.79 volts / 2.4 ohms = 6 watts
4.09 volts x 4.09 volts / 2.8 ohms = 6 watts
Again, a constant voltage device obviously cannot do this, so please do not buy one unless you MUST have a ciggie-look-alike".
Or with a Twist and a Vivi Nova with the 2.4 ohm atomizer head:
3.79 volts x 3.79 volts / 2.4 ohms = 6 watts.
4.09 volts x 4.09 volts / 2.4 ohms = 7 watts.
4.38 volts x 4.38 volts / 2.4 ohms = 8 watts.
In rounder numbers: 3.8 volts gives you 6 watts, 4.1 = 7 watts, 4.4 = 8 watts.
(In "real life" though, you just turn the knob until you like the vape).

"3. Someone mentioned getting two chargers. Is this really necessary due to poor quality or was the poster just being paranoid?"
That could well have been me; I always recommend getting two chargers, so if one craps out, you're not left high and dry.
And 9 watts is a little high for me; I'm generally more at between 5 and 7.
Not sure of the exact differences between the 2.0 and 2.5, except to say "just get the 2.5" (or now, I think, either the 2.5 or the 3.0)
