If your Triton is "non-variable voltage", it is putting out about 3.7 volts. A variable voltage (also called regulated) battery device can put out between 3.2 - 6 volts. This allows you to fine tune your vape. By also changing the resistance (ohms) of the coil in your juice attachment, you can further adjust your vape. Nicotine concentration in the e-liquid is what most controls harshness and throat hit.
I hope that I don't come across as a vaping snob, but the Triton setups are a piece of crap. If you're truly serious about quitting smoking (and stay off of them), get a better setup.
Once you've quit smoking and begin vaping, consider yourself a "vaper". It's different from being a smoker. Don't worry about a vaporizers larger size or "how it looks" to others -- that's not important unless YOU make it an issue. What's important is to get a satisfactory vaping experience with good flavor and decent vapor. You'll get the best flavor and the most vapor production from the more advanced tanks and battery devices. The sooner you learn this, the better.
Advancing Up the Vaping Ladder
You've come to the right place to learn about vaping: ECF. Do your research, listen to what the veterans say. Being that we are so dependent upon batteries to vape, generally speaking the bigger and stronger batteries will provide the better vaping experience.
