Okay, so... I am sure this is a noob questions, but...

Without mentioning formulae or laws:

I am holding in my hand an eGo-C Twist with a Kanger Mini Protank on top. I have a couple of different heads for the Mini Protank: 1.8 ohms, 2.2 ohms, and 2.5 ohms. If I change from the 1.8 ohm head to the 2.5 ohm head, for example, what effect is that going to have on my vape in terms of flavor, vapor, and throat hit when I have the Twist set at 4 volts?

Ohm law E / I x R

E = voltage
I = Current
R= Resistance

E or volts in a waterhose is water pressure..the force pushing the water (aka battery voltage)
I or current is the amount of FLOW of water in the waterhose
R is resistance to the flow (drag, kinks) in the waterhose

Using the formula you can calculate wattage which is the measurement of heat energy the coils can produce given a specific volts and resistance

Too much heat can lead to burning of your juice or melting of your coils (worse case scenario making your batteries so hot they go into thermal runaway and catch fire/explode), too little heat can lead to poor performance and no vapor

Hope that helps

To answer your question now

lower resistance on the chart but increase voltage you up the watts...it might work just fine...but it CAN overdrive your rig...

Everyone tweaks to their taste...turn it up slowly and when you hit that "sweet spot of flavor and vapor" rock on with it...the chart is just a place to get you started

You may have to up your voltage, as it takes more for a 2.5 vs 1.8ohms. Just go up a notch at a time, until you get a little burnt taste, then back off. One of the nice things about the twist is the ability to do this.

Also, it depends on the ejuice you are using. You will find, that some require more voltage, and some require less. Not a whole lot, but sometimes a little.

I only use the 1.8s and 2.2s. If you put that on a meter, you will find that the ohms, are probably higher than 2.5. I use 2.2ohm heads mostly, but on my meter they read 2.4, most of the time.

ps. How can you be a beach boy, and live in TN?;)

1.8Ω - warmer vape, bit more vapour and least battery life. Which all change in proportion as you go up those head sizes. My recommendation is to choose a head you like to vape at and then adjust your volts until you are satisfied with it.

Your throat hit will in large part depend on your juice(pg/vg ratio) and nic level.

The ohms measure how...restricted...the power is.

So the more restriction, the less gets through. Makes sense, yes?

So if you have it at 4 volts and run a 2.5 ohm head...that's OK. If you slap a 1.8 ohm head on there...it may put too much power through at that same 4 volts. (voltage = oomph. Like PSI. Pressure.) So you'd want to dial the voltage down or it would fry the juice.

not if you are pushing it harder

at the same volt more restriction would mean less power...but with that same restriction and you push harder..more get thru

good example!
