Variable voltage / wattage vapes are useful because juices have different compositions as far as percentages of pg and vg. Some juices may taste or vaporize better at higher voltage, some lower.I just started vaping 2 days ago and am in the process of trading a fellow botl some sticks for an itaste mvp 2 (to the best of his knowledge, this is the model). I did some research on it and I have a question regarding the voltage and wattage. It says that they are adjustable in .1 increments. How does adjusting them affect the experience?
Same with the atomizer / tanks. The atomizer that vaporizes the juice will vary in electrical resistance (ohms). So some will get hotter with less voltage.
Some vapes have set voltage, in which case you use rebuildable units on top and adjust the resistance on your atomizer rather than adjust voltage on the vape itself.
Sorry if I lost you there brother. It's probably more simple than I made it sound. Just use trial and error to find the sweet spot on the voltage for the juice you use. PM if you need help with anything.
