Well, it's the first I've actually *understood* about Ohm's Law -- I'm more into computers than electricity, so input/output is a concept I can deal with. :)

And because this thread is where this new light first dawned, I thought it deserved this:

Haha and vaping is a great refresher for those who knew it :D
Um I did once say Electromotive Force in college :shock:

I just wanted something that takes an external battery, for vapocalypse prep -- recently had to trash one of my iStick30'sw due to the battery no longer holding charge, and that annoys me, trashing a mod because the battery is kaput.
I will use my sealed units until they die, but any new mods I get are going to have replaceable batteries. For exactly the same reason as you. Trashing an otherwise functional unit because of a dead battery is ridiculous.

I'm just glad it was one of the iSticks and not one of my CF4's. Which I expect will endure a lot longer, Innokin's quality being much higher than Eleaf's. :D I have 3 vv3's over a year old, the first of which was my ONLY vape for several months... and all still work just fine, I just got sick of the pushed-down-post problem, and the 800mAh.

Weird thing is that it was the iStick that has suffered ZERO abuse -- no dropping, no ejuice baths, nada. But the one I've dropped twice on ceramic tile and allowed one of my kayfuns to leak all over, still works just fine. So weird! :D

My CF4s are still my favorite mods, so I figured if I had some others that I also like, which take external batteries, the CF4's might last a bit longer, not being the sole ones I use. The iPV Mini definitely fits that category. The kbox mini is a good backup box, but again with the pushed-down-post problem. :w00t:

Haha yes the terminology is nerdy ;) your method to understand doesn't work for me engineeringwise, since W isn't really "output", it's more like an adjustment "input setting" the device adjusts the voltage (voltage control) to get the calculated watts you set it at. (W is merely a calculated value of Vsquared/R). What is actually "output" is current, the value I= V/R.
Power can be calculated using V x A or Vsquared/R and maybe some mods measure current, but mine only measures V and R. But whatever works for you :)

Now that is confusing :D

You can't adjust wattage. You can only change wattage by adjusting either voltage, amperage - or both.

Neither volts or amps can be measured as anything other than volts or amps. Watts, on the other hand, can be converted to other units of effect - like horsepower.

745.7 Watt = 1 horsepower .

My point is: Watt is not a measure of electricity. It is a measure of effect (energy output or expenditure), regardless of the energy coming from amps*volts, gasoline+sparkplug or legs+threadmill.

Curious, did you even read my post on basic electricity a few posts back? Lol
You can adjust the wattage setting. Which in turn sets the voltage ;)
Thanks for the horsepower conversion :blink:
Update:
I do see where you are coming from, if we were to measure power with a true wattmeter, the meter would measure current and voltage as inputs and the meter would then calculate and display Watts. From all I've read about regulated mods, that's not what they are doing however (displayed watts would bounce around a little if it were ). The voltage or watts settings on a mod are user setting inputs (setpoints in the control system world) and the regulated mod then controls voltage to the coil based on those setpoints, typically using pulse width modulation. What is being displayed on my Istick 30 and 40W mods is the voltage or power (watts) setpoint that the user sets.

The vast majority of vapers don't vape at terribly high wattage; heck, the vast majority may still be vaping cigalikes or Ego+clearo.

I have no use for wattage over about 11w -- like the iTaste vv3's. But, the high wattage boxes either have a high-capacity battery, or it's suggested that you use a high-amp battery in them; for me, that just means really long battery life -- a wonderful thing!!!

I pretty much agree with you. I used regular ego's for a while - my issue was they died and I vape a lot. Then I went to an istick and used my evod glass and I really had no issues and it was right about 11 watts but I was refilling all the time. Now I am on the subbox nano with the nano tank and my trusty 12.6 watts (which I read somewhere was a really good wattage) and am super happy. And I was a crazy heavy chain analog Marlboro smoker. I carry a spare battery just in case and all is good. And I blow good vapor - can't see wanting to vape up a whole room...

The horsepower conversion was not added for flamboyance (or to lecture you) - it's there to illustrate that a Watt is not a component of electricity. Volt and Ampere are units of measure quantifying the components of electricity. Watt is a unit of measure for quantifying the effect (or potential effect) something (i.e electricity) has on something else (i.e a heating element).

Agree with this. The points you made regarding current and voltage being physical electrical properties and power being a calculated entity (I tend to look at it as a measure of the rate of energy being used) were very good points and I should have said as much in my response.
