What I'm trying to understand is can you get that much of a different and better vape from a mechanical mod/RBA v my Provari/cartotank? Because I am willing to learn.. I used to be a gemologist so I'm okay tinkering with small stuff.. Is it super hard? Is it worth the time and effort? Or do you do it cause its fun and a hobby?
Not necessarily...
Think of in these terms...
If you want to build an electrical circuit it won't take long before you discover that you need to include a resistor or few... So you decide to go shopping for resistors.
You get to the electronics store or website and you discover that resistors, in addition to having a stated resistance, have wattage rating. The teeny tiny resistors may be 1/8 watt the big beefy ones that look like bricks with two wires may be several watts...
Bear in mind that the teeny tiny resistor and the big beefy resistor offer the same resistance. They just have very different wattage ratings.
So what the hell does the wattage rating have to do with anything??? Well... It tells you how much power can flow through the resistor before it heats up to a point of possible failure. The big resistor can take on a LOT more power before before it begins to heat up.
So... How the hell does that translate to e cig atomizers??? Well, that's easy. An atomizer is a resistor. It's a resistor that we WANT to get hot.
So back to the teeny tiny/big bulky resistor analogy... The thin 34 to 36 awg wire that's in your cartos would be the teeny tiny resistor. The ultra thick 28 & 26 awg wire that folks are using in their RBAs is the big beefy resistor.
It takes A LOT more power (watts) to heat 28awg wire than it does to heat 34 awg wire, for a given resistance. Since a mechanical device can't control the voltage it has to rely on amperage to heat the thick wire coils.
If you'd like to test for yourself, go get two new carto... Both of the same resistance (ohms)... One should be a single coil and the other a dualcoil... Fill them both...
Now bear in mind that a dual (lets say 2 ohms) is actually 2 4 ohm coils being run in parallel. So the dual coil will have 4x the wire as the single coil and therefore 4x the "wattage rating"... (note... multiple thin wires is no different than a single thick wire)
Start with the single coil and dial in the voltage to a point where you .... it. Now trade it out for the dual coil (without making any adjustments) and give it a vape...
So... Odds are, the great vape you're getting from your "thin wire" cartos isn't too far off from the great vape others are getting from 28awg in an RBA... You're just using a lot less power in the process.
