Once you have variable voltage, you will want a backup that also has VV. I'm actually thinking my next eGo batteries will be Twists. I love the Provari, but there are times when I want something that is light in the pocket.

The Twist, with its 2.5A limit will perform just fine with 2.5 and 3 ohm atomizers, but will start to downshift if you decide to use something like a DCT carto tank with a 1.5 ohm coil. That's a 3 watt load at 4.5v, but you can get a good vape at 3.4v or 3.7v.

A standard eGo at 3.4v gives me a perfect vape with the Smoketech DCT at 1.5 ohms.

The Provari is definitely great. I just got mine. The ohm read function is great for dialing in exactly what voltage you need. I didn't think that I would use the battery voltage check, but it's perfect for knowing when to charge your battery without over-discharging it. If money is an issue, I would go with the Lava Tube or something similar, but if not, the Provari has definitely been worth the money so far.

I think you meant a 3 amp load at 4.5V. A DCT with a 1.5ohm dual coil carto, running at 4.5V will give 6.75 watts on each of its 3ohm coils and draw 3 amps total. What does the Twist do in the case of overamping? Adjust down? Let you crash the battery? Shut down?

Anyway, that same carto will give a cold, wimpy 3.85 watts with a standard ego on each of it's 3ohm coils. I'm not sure how that could be a perfect vape. When the v1 Lavatube cut it's voltage to 3.7 with a dual coil, everyone complained that Lavatubes couldn't be used with dual coil cartos. And I agree. You need about 4.2V min. for a good vape with a dual coil.

The optimum resistance for a Twist would be 2ohms. That would give you a wattage range from 5.4 to 11.5 watts with a maximum of 2.4 amps.

A 3ohm carto would top out at only 7.7 watts at 4.8V. You'd spend virtually all the time vaping between about 4.3 and 4.8 volts, which would give you 6.2 to 7.7 watts. That's only about 1/3 of the Twists useful power range.

Laura, you don't have to go around chasing 3ohm stuff. Any resistance you have will work well on your Provari; you'll just dial the voltage up or down.

Thanks - I'd rather not go chasing ohms - I'd like to wait until I have the Provari and see what I think I need - I have up to 2.8 ohm attys/cartos so I'll see how I like that.

To be honest, all the watts/ohms/voltage/amps confuses me. Hopefully I don't need to know the specifics to that in order to use the Provari correctly.

Well, thats the advantage of such mod. Whatever you screw on it, you'll be able to dial it up or down, to your liking.
And no, you can of course adjust the voltage to your taste. Too weak/cold/anemic? Up the voltage. Too hot/burning taste/hard on inhale? Lower the voltage. Its simple as that, if you don't like to do the math :)

It would help but you will figure it out quickly. There are some charts somewhere that show different ohms @ different volts. It shows a safe vaping range and the wattage you will get. Wattage is easy to calculate. (volts x volts) then divided by ohms. For example 4v with 2 ohm atty. 4 x 4 = 16 then 16 divided by 2 = 8 Watts. You will figure out the typical wattage you like by testing it out. Then you can calculate what voltage to use depending on what atty you are using. Amps you dont need to worry as much with the provari high 3.5 amp limit unless you are trying to use an obseen amount of current.

I have 2 twists and I think 3 is optimum. They go dead faster then they charge the way I use them.

I do have 3 of the 1000mah Twists although I am keeping 2 in reserve right now. The one I use (between 3.6 and 4.2 volts) lasts just over 24 hours. I'm guessing you must be using a 650 mah at 4.8 volts to get that short a life from it. I am also using a 1100mah pass-through battery while the Twist charges. It usually lasts me about 12 hours depending what I am using on it.

If you are getting a third Twist then probably a 1000mah would be a good choice.
Or maybe a VMax Lol!

I just got the 650 mah Twist and love it !

Liberty flights has some left on sale for $19.95. Look under eGo C batteries and click the 20% discount. Shipping is only $3.

I'm using mine with a 1.8 ohm LR type B tank. The juice really sizzles at 4.8 V, so I find that 4.2 V is about right. That's about 10 watts. Noticeably better than a standard eGo or Riva battery. No problem with 1.8 ohms. Just a little longer than a standard eGo battery, but still easily fits in my shirt pocket.

Glad I could use all my old stuff with the Twist battery.

I'm not a chain vaper, but my battery has gone for over 15 hours now. Will charge it over night.

No offense to anyone happy with the twist, but I was a bit disappointed in mine. Probably due to my LR cartos. Nevertheless, I broke mine ( sat on it) and moved on to a LT which I have been quite happy with. Best of luck with yours!

Why were you disappointed with it and how did LR carto affect it? I have mine just about a week or so and I'm using LR Vision/Stardusts. So far no problems.

The term "LR" is different with each vendor, it seems. Also, the QC is not that strict (understatement Lol) and the resistance can vary quite a bit even in the same batch.

I have 2 of the 1000 mah twist and I have to recharge both of them through out the day even when both are fully charged when I wake in the morning. I usually use some where between 3.6 to 4 amps.

The regular 1000 mah batteries last a good bit longer.

I'm assuming you mean 3.6 to 4 volts since the amp limit for the Twist is around 2.5 amp.

1.8 ohm at 4.2 volts is near the amp limit and it is a fair amount of watts. The beauty of it is, for a $20 device, it can hold those watts for a reasonable amount of time, unlike the 3.7 volt clones.

Agreed, time is a relative term (get it, Lol) when comparing how long the charge lasts. Some people take 10 draws an hour and some take way more, so that is impossible to predict how long the charge will last for someone else.

For the price, it is way more than I expected (I paid $30) and I am very satisfied.

Just wondering....
Will the 650mah Twist vape as long as a 650 Kgo or does the added electronics make it less efficient?
I assume vaping at lower voltages (given the same carto resistance) will extend the vape time.
How does the voltage setting impact how long you can vape between charges?
If I get 5 hours out of a 650 mah Kgo, will I get the same out of a 650mah Twist if I vape at 3.7 volts?

Just ordered a 650mah Twist to see what all the fuss is about. The 1000 mah seemed too long to fit comfortably in my jeans pocket.

I was using DC LR cartos and tanks and no matter what voltage I adjusted it to, the difference in vape quality was slight. Guess I was just expecting more. I know there are limits to what it can do with a LR carto. The form factor was also uncomfortable for me. LT seems a better fit for me and seems to vape much better, although I believe it is also limited to 2.5 amps. I finally bit the bullet and ordered a Provari yesterday. My expectations are high again!

If everything else equal running higher volts but at the same wattage is more battery efficient since you are using less amps vaping at higher voltage and higher resistance. 2ohm @ 4v = 8 Watts = 2 amps. 8ohm @ 8v = 8 Watts = 1 amp. Hopefully the math I did in my head is correct. Both the same wattage but less current should yield better battery life

I see this around the forum a lot. Its not correct.
Voltage over the battery voltage must come from somewhere, and when looking how long will the battery last, you shouldn't be looking at the current going through the atty, but the current being drained from the battery.
In other words, if you set your device to 5V, and you have a battery giving ~3,7V, the drain from the battery gets higher. There's also some loss in the booster circuit, since nothing is 100% efficient.
