I need to save this, memory is not what it used to be. Thank you!

Thanks so much! Seems the more I learn the more ??? I have.
Thank you! Although the cigalikes suck (and not in a good way) I'm not so much interested in massive plumes or heavy throat hits. Flavor and nic are more of a concern at this point. Who knows? I may find my Egos to be just what I need until much further down the line.

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.
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.

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
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.

Right. That said, with unregulated devices, batteries come off the charger at 4.2v, which may be hot enough to fry a filler in a LR cartomizer or deliver a nasty dry hit with a LR clearo. The rest of the time the battery runs at 3.7v, then the voltage sags again until the cutoff point--usually around 3.1 v or so.
