Joyetech eGo-C Twist Review

It seems like Joyetech has been doing overtime lately.  First was the eGo-C followed by the eGo-C Type B.  Now we have the latest and greatest from Joye, the eGo-C Twist battery.  This is Joye’s entry into the world of variable voltage and promises the performance of a mod in a small(ish) eGo package.  Read the rest of this Joyetech eGo-C Twist review to see how it stacks up.

Who’s it for

  • Fans of the eGo form factor who want a little more performance and flexibility.
  • People who want variable voltage without the hassle of toting around a big battery mod.
  • Bargain hunters looking for variable voltage for under $30 (Check out Vapor Alley for options and prices)

Joye eGo Twist Design

At first blush, there does not seem to be much difference at all between your garden variety eGo and the eGo-C Twist.  You’ll find the same design in both including the iconic double threaded top. Like most new eGos, the Twist has a 5-click on/off feature.

twist and standard side by sideIf you have a standard 650mAh eGo battery, you’ll notice immediate difference.  The Twist which also carries the same mAh rating is considerably longer than a regular 650.  The eGo Twist is much closer in length to a 1000mAh eGo.  That extra circuitry had to go somewhere. Note: Twists are now available in several higher capacities as well.

The other difference is much more subtle.  There is what appears to be a cap on the bottom of the Twist.  This looks like the cap found on USB pass-through versions of the eGo battery.

If you look very closely you’ll find some small markings on the lower part and battery and the cap.  These markings are to show the current voltage setting of the eGo Twist.

The Twist allows you to adjust the output voltage between 3.5 and 4.8v by (wait for it) twisting that cap.

The eGo-C Twist uses what’s known as boost/buck technology to adjust the voltage using a single 3.7v battery.  This is the same technology found in the ProVari and Lavatube.

The great thing about this technology is that it keeps the voltage consistant throughout the battery’s charge cycle. Even if you just sort of set it to a single voltage and forget about it, it will maintain that setting the whole time.

Joyetech eGo-C Twist Performance

Let me just jump to the first thing I look for when evaluating a variable voltage device.  Can it run a dual coil cartomizer at the highest voltage setting?


In that regard, the eGo-C Twist behaves more like the Lavatube than the ProVari.  When I tested the loaded voltage output using a dual coil, the Twist dropped the voltage down to 3.7v despite being set for higher voltages.

The other thing is that it doesn’t seem like pushing a lot of voltage through a dual coil is necessarily the eGo Twist’s niche in the first place.  I really see this as a somewhat more simple device than that.

It’s a small and elegant device that provides some degree of customization to the vaping experience and not a flat-out high performance machine.  It does a good job of sticking to the selected voltage and maintains all the characteristics of an eGo device.

I did notice the occasional migration in voltage where it would drop up to .1v from time to time.  It didn’t happen often, and I never saw it go over voltage, but it is maybe a little less precise than the ProVari.

Unlike the Lavatube, the eGo-C Twist held the voltage where it was supposed to be until the battery drained and shut off.

If nothing else, the Twist is great from the standpoint of outputting a consistent voltage.

From a battery life standpoint, despite running it at higher voltages, I found that the life was comparable to a standard 650mAh eGo.  I got several good hours of moderate use between 4.0 and 4.5v.  I didn’t crank it to the max due to that whole dual coil thing I mentioned earlier.

If I wanted to pick nits, I suppose I could bemoan the fact that there was no LCD readout, but that would have added to both the size and the price of the Twist.

Too Long; Didn’t Read

The Joyetech eGo-C Twist is an easy to use and accurate variable voltage eGo e-cigarette that adjusts with a simple twist. I think if you are an eGo fan, you should have at least one of these things in your arsenal.  You can buy one starting at $25.99.  It’s hard not to add one to your eGo collection at that price.

If you are looking for something to max out your dual coil cartos, however, you’ll probably want to keep looking. You can either look at the ProVari V2 if you have the budget, or something like MadVapes variable voltage box mod if you’re looking for something more wallet friendly.
