I'm surprised no one has mentioned the other advantage of vv/vw devices. With a vv/wv, the voltage/wattage stays pretty much the same during the life of the battery charge. With an unregulated device, the power of the battery gradually trails off, giving you less vape/flavor/th as time goes on, until in the end you get almost nothing. Also, a regulated device can give you 6 volt performance from a 3 volt battery, and many would say that a 3 volt is safer than a 6 volt or two linked 3 volt batts.
That's nice to know! Thank you! If I see it trailing off as the batt dies, I'll know what i need.

It all comes down to V = iR (Ohm's Law, Voltage = current x Resistance). Yes, I know, we actually get to use what we learned in high school in real life.

Depends on the Resistance(Unit: Ohm) of the coil in cartridge, the Voltage can be tuned to that "perfect" setting so that the right amount of i, current(Unit: Amp), goes through the coil.
Go to this site if you want to know more details (Science behind EV - Proneodox)

As per various voltage per various juices, I'm sure there is some effect, but our taste senses are not that sensitive. That's like asking, should I bake frozen pizza at 400F or 405F. I can't tell the difference even if there is one.

Some mods have power setting, so you need to understand P = iV (Power = current x Voltage). The unit for power is Watt. Power is just another way to represent setting.

Some nominal setting are:

Voltage: 4-5 V
Resistance: 1-3.5 Ohm
current: 1.5-2 A
Power:4-8 Watt

Example:
If you set 4V with 2Ohm coil, i(current) = V / R = 4 / 2 = 2A.
Since P = iV = 2A x 4V, the Power is 8 Watt.

In English, higher the voltage, the hotter the coil get. Lower the coil resistance, again, the hotter the coil gets. The hotter the coil gets, it burns juice faster, means more vapor. One may say, why not make it super hot and done with it. For one, it can melt the plastics around tank/cartridge. Also, the high temperature of coil consumes battery faster. It also "burns" the fiber wick in the tank faster, and creates carbon around the coil.

Having said all that, it only matters to the people who wants that extra bit of control.
Vendors usually pre-set their device to match their tanks/cartridges for the best performance.

Happy vaping:2cool:

High school?? Class of '76 here, you think I remember any of that? LOL

Good, that's what I ordered, ummmm 900mah, 2 w/4 clearos and a bunch of other stuff.

Oh, I thought you were ordering vv batteries?

If they are regular eGos, I recommend 1.8 or 2.2Ω atties.

900 mAh is the capacity of your batteries--they should last roughly 8-9 hours of moderate vaping at moderate wattages. Think 100 mAh = 1 hour of vaping.

No, I had already ordered but then with everything I read, wondered why I would want or need a VV. Actually the 900 was a mistake, I meant to get 1100, but messed up. Oh well, they should be ok for the short term anyway.

They'll do just fine. My eGos are 650 mAh.

Good luck!

Actually, my regular eGos are 900 mAh, my vv eGo-class batteries are 650 mAh--they are about the same size. I don't like them too long.

Hey ncpatches,

I started vaping over two years ago and I'm still using my basic ego 650 mahs. I was a pack a day of reds for ten years.

They work. And with the new clearos, they work really well. It didn't stop me from ordering a bunch of new stuff, but you won't be disappointed with them!

That's nice to know! These cigalikes are so awful, I can't wait for my stuff to get here. Maybe then I can let go of the stinkeys for good.

Ncpatches, as a new vaper myself I often wondered the same thing....I was happy with the way my juices tasted on my simple ego setups. Then I took part in a co-op and got a VTR. There is a very real difference. I dont really understand the ins and outs but I can attest to the difference in how my juices taste in the very same protanks. Each juice seems to have a "sweet spot" where the flavor just peaks. I just adjust the watts using the chart that is floating around and PERFECTION. My Lucky #11 is perfect at 5.5 watts but my DIY peppermint hits perfection at 10.5 watts...the volt thing I have not figured out as of yet:vapor:

What is a VTR?

(Grumble: I wonder if I'll even end up back in this thread to see the reply if there is one; so many posts posting away per second on this forum its not possible to keep up with most of them.)

Wow, I didn't know there are un-regulated (DC voltage step up converter) EVs.
Isn't that what we normally called a flash light, not an electronic vaporizer?
LoL

Happy vaping :2cool:
