I just picked up my first high-power regulated mod, an iTaste MVP 3.0 Pro (60 W / 9.0 V / 17.5 A / 0.2 Ω) and I am loving it. I started with my usual build on my mechanical mods, a 2 mm ID 0.7 Ω single coil with 26 GA Kanthal, and it works amazingly. With a mechanical mod, I could feel the power dropping off almost immediately, and I swap out batteries when they are at around 4.0 volts. With the MVP 3.0 Pro, there's (obviously) none of this -- set to the same wattage (25 W) the vape remains consistent.

I am a bit confused with people using very low sub-ohm builds on their high-power regulated mods. Isn't the whole point to be able to reach higher power levels without having to use extremely thick wire and super low-resistance coils? Why keep doing this if you can use thinner wire (which heats up more quickly) and/or more wraps (which increases the coil surface area and heats juice more evenly). And when you fire a higher-resistance coil at a higher voltage, you use less current than a lower-resistance coil at a lower voltage, but still have the exact same wattage. So your battery lasts longer -- a 0.25 ohm coil fired at 50 watts pulls 14 amps, but a 0.75 ohm coil fired at 50 watts only pulls 8 amps. So we're talking almost double the battery life with the higher-resistance coil (not really an issue with the huge 4500 mAh battery on the MVP 3.0 Pro or a dual 18650 regulated mod, but on smaller mods and single 18650 regulated mods this is the difference between getting a full day's worth of heavy vaping and having to carry a spare battery or recharge the spent one).

Is it just a matter of people used to the limitations of a mechanical mod and sticking with what they know will work, even when there is a better option? Or maybe keeping the ability to put the same atomizer on either a regulated mod or a mechanical mod and still be able to vape at high wattage?

Biggest thing is that while people are using new tech... the knowledge of coil building is still, MECH based. Or oriented to getting flavor from fixed volts.

IDK, why people are still building subohm...... Probably has to do with ramp up times and cloud making and immediate gratification requirement of life today. It's all about, get as hot as you can as fast as you can using the most power you can in order convert the most juice to vapor as possible.

Me, I'm a minimalist at heart. I try to get the most, from the least effort. Maximum flavor from the least amount of juice consumed.

Using massive exotic or multi strand coils the resistance just naturally comes out low, and once you have half a pound of wire in the atty you have no choice but to brute force it with high power if you expect it to heat up before you go to bed, But for an average build no, subohm is not necessary anymore


Personally i run some simple high gauge builds on my mech and can easily run down to 3.2 volts and being ribbon still put out some clouds.
