Question about variable voltage

[lviperz]

I have an ego-c upgrade and just found out I have the option to use it in a fixed voltage or variable voltage mode. I understand electricity, ohms and watts, but I was wondering what the benefits are of using one over the other.

I understand the fixed voltage will give me basically the same voltage through the life of a charge. Knowing that with the same clearo at 1.8 ohms I will have the same constant vapor.

But in variable voltage mode, the voltage can be higher at first and lower as the battery drains. With the voltage getting lower as the battery drains and still using the same resistance, wouldn't I start getting less of a 'hit' so to speak? Is there another reason one would want to use variable voltage like this? I could see variable voltage to set the voltage you want based on the atomizer you are using, but I don't see a reason for it as my ego-c manual explains it.

It really isn't variable voltage, it's unregulated voltage meaning it is the voltage that the battery is capable of at any given time during the life of the charge.
A variable voltage device can deliver more (or less) voltage than the battery would be capable of delivering without the electronic circuitry.

The benefits of unregulated voltage instead of regulated voltage is simply in the eye of the beholder. They each have their up side, and their down side. Your eGo upgrade simply allows you to choose which you like best.

Ahh, thanks for that. Makes sense now. Think I will stay with the 'regulated' voltage for simplicity and a constant vape.

Lets say you like vaping a 2.2 ohm atty/carto at 4.0 volts... which would be about 7.3 watts. If you only had a 3 ohm atty/carto available, at 4 volts you would vaping at about 5.3 watts, and that would likely be a much less satisfying vape. If you had a VV device you could adjust the voltage up to about 4.7 volts to get the the power usage (watts) back to around your desired 7.3 watt level.

With an unregulated battery, the voltage with a fresh, full charge will be around 4.2 volts, at the time the battery needs to be recharged it will around 3.2 to 3.4 volts, so obviously the wattage level you are vaping at will vary greatly, from about 8 watts at 2.2 ohms on a freshly charged battery, down to about 4.8 watts when the battery needs to be recharged.

A regulated battery (Ego), or variable-voltage device, will hold the same level of voltage throughout the usable charge of that battery before it needs to be recharged. With an Ego type device you change the resistance of the atty/carto to give you your desired wattage level. With a VV device, you can adjust your power output to give you your desired wattage across a broad spectrum of atty/carto resistance.

Hope this helps.

Mike, thanks for all that and I do understand that. But my question stems from the 2 different modes I can put mu ego-c in. The first mode is regulated to remain at a constant voltage. The second mode is unregulated as you describe. So my question is, why would a person want the voltage unregulated? I understand variable voltage and that makes total sense.

To me it almost sounds like the unregulated mode of the ego-c is hype to make it sound better.

Not hype for me! Unregulated starts at 4.2/3.7 and runs warmer like that for hours.

It's then akin to non-Joye egos like Riva or Kgo.

Sorry lviperz, guess I should have been more attentive to your question.

As r77r7r and tj99959 said, in unregulated mode it provides a warmer vape with a fresh charge. How long it stays at the higher level depends on whether you are a heavy or light vaper, in conjunction with the resistance of your atty/carto. In this mode it's still going to decline in performance over the useful charge of the battery, unlike a regulated or vv device.

The manufacturer is trying to provide a two devices in one versatility to create a niche following for this product. Maybe it's not hype, but I think it's a bit of a gimmick, and like you, I prefer the consistency of a regulated or VV/VW device.

Ultimately, like many things in vaping, just a matter of personal preference.

 

[r77r7r]

Maybe what's needed here is a different viewpoint. Here's mine. I'm ONLY going to use a 650 ego for it's small size. It's gotten me off of smokes and is all I Want from a PV.

I prefer Joye products. Up until the release of the Upgrade, all I had was a cooler vape at 3.4v. Now I have much warmer @ 3.7v Keeping the same Size. That's all it is.

A gimmick to me would be a puff counter or useless "selectable voltage". When a progressive vaper wants more ( I don't), They can use the Twist.

Have an eGo that fires @ 3.3 volts regulated and a Kgo that fires @ 3.7 volts unregulated. I notice the diff. The only bonus in firing at 3.3 volts is battery longevity before recharge. It all depends on the individual's wants and needs IMO.

I have one of these batteries too. This may not answer your question (it's a copy/paste from a review I wrote about it).

In the unregulated mode (Joyetech calls it "Battery Voltage" mode), the battery comes off the charger at around 4.2v and will fire at that output. The voltage then goes down as the battery discharges. From what I’ve been told it goes to ≈ 3.7v and hangs around there for awhile before further discharging, but I have no way to verify this. In the regulated mode, the battery fires constantly at 3.3v.

Personally, I think it's pretty much a gimmick, or concept over function fail. The point of VV is to be able to adjust the volts to where you want them to be. This battery does not do that.

To make the voltage even less operator variable, in the regulated mode the button is white when fully charged, then turns darkening shades of blue as it discharges. In the unregulated mode the button stays yellow. If one is vaping in the unregulated mode, there is no way to tell what voltage you are (roughly) at without switching to the regulated mode and trying to guess if the button is cobalt or cornflower blue. I just use mine in the regulated mode like a standard eGo.

 

[r77r7r]

How about thinking of the Upgrade as being like the very popular Kgo or Riva? Just with the choice of also being Regulated?

You simply have to skip the hype if a supplier wants to push this as something it's not.

i like it for adjusting to differnet resistance gear ( swapping from evod to clearos with diff res )

Just got two eGo upgrades today and I'm loving it, regulated mode is fine for me. And I'm happily looking forward to the extended charge life, and batt life as well.
