Why change from a real VV mod, to a cheap version with limited functionality? Thats kinda like when I made the dumb mistake and bought a Buzz Pro when I already owned a provari--- settin yourself up for a let down.

I want a form factor for 'going out' purposes.

Other than that, I have been extremely happy with my ProVari (I've had 4 at one time).

Riddle me this...........

How does the vv eGo stay at 4.2 volts throughout the vaping time? Has anyone actually measured it at, say, start, 25% done, 50% done, 75% done?

Curious. The answer to this question, OP, is also the answer to your question. And I don't have it, but I'll ask so you get the answer too (assuming someone knows the answer. I suspect I know, but am not sure and have no way to verify it.)

Just ordered one today - the downside according to a few I hold in great esteem is the quality of the plastic ring at the button which tends to pull apart like the early TMax did. However the VV part might overide that consideration as long as one is careful with it. I have a vv Big brother and except for a strong espresso ejuice, I find I keep the voltage at 4+ for most flavors as do many vv users have reported, so the 4.2v might be all one would need and for the lighter flavors going to the 3v area should help flavors that don't do so well on the regular eGo/Riva batt.

It doesn't maintain voltage. Starts high and declines with use. At 2 bars it was 3.7v for me.

That was my guess. Sounds like it doesn't have a booster circuit.... it follows battery voltage... like a 3.7 volt mod. So to say 4.2 volts at the high setting is only for a fresh charge of a Li Ion battery for a short duration.

Li Ion batteries follow a voltage curve. Any 3.7 volt mod is either regulated at given voltage (less than 4.2) or is following battery voltage. Let me see if I can dig up a chart <rustles virtual papers on the net>

NOTE: Not my chart... but gives an idea even if actual performance varies a bit.

So 4.2 is only for a very limited time at the top end. Mostly they stay around 3.5/3.7 volts for quite a while, then drop suddenly at the end.

Would be similar to a nico-stick, e-power, or some other 3.7 volt mod with similar sized battery that follows battery voltage. However, the other (lower) settings are probably PWM regulated and give a more consistent performance for X volts through most of the curve.

The short of it: It is a variable voltage 3 position setting. The top setting is just "max battery voltage". The other settings are regulated at desired voltage as long as the battery produces that voltage. It may cut off when below that or just pass the lower voltages through and cut off at some even lower point; IDK about cut-off points.

Best guesses.
