I use VV to adjust for "mood". Sometimes I want a strong vape. Sometimes, usually early morning and late evening, I want less TH and a smother vape.

I don't think VV is the answer to everything as, personally, I was doing just fine with a satisfying vape from my Bolt and Boge LR's. But VV does have its advantages.

Wattage is part of the big vapor formula, so is high percentage VG e-liquid.

VG is actually Glycerin USP. You may purchase it inexpensively at any drug store.

Most vapors prefer 6-8 watts which can be supplied with a regulated single voltage APV like the E-Power 14650. You don't need a high wattage, high voltage or variable voltage APV or PV for that.

Regulated 3.7V means that the APV is going to deliver 3.7V so long as the battery is charged somewhere between the full fresh charge of nearly 4.2V to the nominal charge of 3.7V. In the E-Power 14650: when the battery falls under 3.7V the APV voltage will be equal to the battery voltage (less than 3.7V). When battery voltage falls to 3.4V the low voltage signal will flash meaning it's time to swap out to a fully charged battery. If you don't the E-Power 14650 will soon shut down.

In my experience, the E-Power 14650 delivers 3.7V and 6.8 watts from the ICR 14650 battery for about 15.5 hours or 2-3 ml of vaping. It will deliver 8.05 watts with a few hours less battery time. At 6.8 watts it delivers 3.6 to 3.4 for only 30 minutes or so before the low battery light flashes and the device shuts down.

What wattage can you get from regulated 3.7V?

With a 1.7 ohm LR single coil carto (or other atomizing device) you will get 8.05 watts.

With a 2.0 ohm LR single coil carto you will get 6.8 watts.

With a 2.3 ohm LR single coil carto you will get 6.0 watts.

So you really don't need VV (variable voltage) or high voltage to get 6-8 watts of vaping power. Regulated voltage at 3.7V will do the job at less cost with less electronic circuitry leaving more room for larger capacity batteries in the APV body. A mechanical or unregulated APV or PV will not deliver vapor with consistent quality, as the device voltage always falls as battery voltage falls.

If you want to vape with higher than 8 watts sure, go for high voltage or a VV that is capable of more than 8 watts. However, folks wanting more than 8 watts of vaping power will remain in the minority of the vaping world.

With a VV, you won't need to worry about the ohm of your carto/atty. Low resistance, just dial the voltage lower. High resistance, just dial it higher. Very versatile and make more choices of carto/atty available to you with just one battery.
I would disagree. With a VV device you do need to be conscious of the resistance of your atomizing device, whether carto, atty, atty/cartridge or clearo. Unless the VV device has an auto set circuit to prevent you from supplying too much power to an atomizing device of a particular resistance, you can burn out the device. Not all VV devices are created equal. It seems like many of the new VV devices from the far east deliver higher voltage than indicated and are burning out a lot of atomizer devices at the lower end (3.0 to 4.5V indicated) of the power range.

If you like cold, inconsistent vapor, don't bother with VV. If you like warm, consistent vapor, then get a good regulated, boosted VV/VW model and use any of many different heads on it. Many of us like the warm vapor from vaping in the 4.5v- 5.0v and 8.5 watts to 10 watt range.

I get a good warm vape using lr.

It is like having different gears, some flavors like fruits, desserts seem best at a lower volt setting, tobacco's, chocolates, coffee's are better a bit higher volts. You can also use low resistance or high resistance carto and adjust your volts. You just have more settings, more options. bnrk

There are only three conditions where I mess with my VV settings and consider VV to be a major plus:

...Finding the 'sweet spot' for a new flav and/or carto/clearo/carto tank*.
...When I have a carto that I want to 'stretch' it's life span a bit.
...Occasionally I need to drop the voltage early in da morn. Once my 'buds' and throat acclimate, I'll adjust it back up.

*I'll adjust the voltage up until the vape gets harsh. I'll then back the voltage off a tad for max flav AND vape.

Bottom line for me... If ya can match your joose device and PV fixed voltage, then no need for VV. Otherwise, ya won't go back once ya go dere!

My opinion about VV has been evolving.

I have a number of VV devices and I have a number of non-vv devices. Since I spent about 2 years without VV, I put in the time, effort, and money to figure out what worked well for me as far as attys/cartos paired with juices at voltages I could create before I had VV. I have quite a few favorites that are not VV.

I do not think that vv should be the only feature of a PV to look at when choosing one. I've seen many people end up unhappy and with a list of complaints about the device they chose because they did not consider other features and only focused on VV.

OK. that said: Regulated voltage is a big difference. Variable regulated voltage is not only a big difference, but is also often a real pleasure. Others talked about being able to tune your flavor and throat hit - and about being able to heat up or cool down your vape according to mood or time of day - and about regulated voltage offering consistency. That last point is the big one. Consistency from the first to the last vape of the day is a real luxury.

Going back to what I said about not focusing on a single feature of a PV - In my case, the very first thing I look at is the atty connector. I don't know how many cheap connectors have let me down. A quality connector is worth its weight in gold. Next, after I discovered feeders, I decided on a form factor. Though I own a bunch of tube mods, I won't be buying any more of them. I really like feeders. My two most used PVs are a VV top feeder and a VV bottom feeder. What they give me is all day battery life - all day juice supply on board - and complete consistency all day long. I carry a single vaping related item with me and no supplies whatsoever. That's a lot of freedom.
