…The Twist will let you destroy its battery and/or burn out your coil. The Twist battery is only rated for 2.5amps…The Twist will let you [exceed its current limit] for a while until the battery is permanently damaged and it just sits there blinking at you.
That contradicts
every single thing that I've read, watched, or experienced about the twist as well as most of what I've read about batteries.
The twist is limited to ~2.5A, which means it won't run dual coils. Neither will the early lava tubes, which some people are still selling. There are some revisions that will run them okay, but I honestly think that based on math, dual coils are a joke anyway.
What that limit means is that the Twist won't go over about 3.75 V driving a 1.5 Ω dual coil, which will give you a marginally better experience than a standard resistance carto on a cig-a-like battery. Except that some people show less than that on certain meters, probably because the boost circuit it uses actually generates a wave instead of raw DC current and they don't know that their meters are measuring wrong.
If you know about the math or care to, watch steeljan's torture test of the ego twist on youtube. It's impressive. It also takes like half an hour.
The Twist
does have shortcomings, but I don't see
any reason to buy any other ego-style batteries while it exists. If it's not good enough for you, move into high-volt Mods.
Dual coil 1.5ohm cartos aren't very good for under 4.5 volts.
I'm using a simplification and pretending all the VV devices actually output DC. They don't, but the math is close enough to make my point.
So……assuming you're not current limited…you're suggesting 13.5W……which is about the same temperature in each coil as 6.75 W on a single coil……which is about the same as a LR Boge on an unregulated 3.7V mod……just draining your battery faster, stressing your wicking harder and
maybe producing vapor a bit faster.
See why I think dual coils are a joke? If you like warm vapor, dual coils just mathematically aren't the right thing to use. If you like short drags and cool vapor……then just don't use cheap VV and math says you'll probably like dual coils.
Personally…based on my limited experience……I don't think there's any reason to try them unless you're going to get up towards 20W (5.5V, drawing 3.7A)……which gives 10W per coil……which tops out about where a high-ish LR carto/atty does on the Twist……and is too much for the Provari (IIRC), Buzz Pro (IIRC), Darwin, or Kick. Based on just the numbers, there are a few well-respected reviewers that agree with that based on experience.
So, if you want something like a Twist, you'd theoretically want a good range of power, right? How high can you go?
~12W (2.5Amp limit at 4.8V)……which happens right about 2 Ohms…maybe a little higher if I'm estimating the real numbers from this approximation correctly. How low will it go? At the bottom of the range…~5W.
A $25 VV device that goes from 5 to 12 W seems pretty good to me, and that's what happens when you stick around 2 Ohms for your carto/atty/clearo on the Twist. If it's a little off that, you just sacrifice some at the top…which is no big deal.
For reference…the Kick tops out at 10W and a standard, cheap cig-a-like with an SR carto is probably putting out about 4W.
