Like, ohms and stuff...

I was looking at getting some cartos, but i asked what ohm I wanted:

2.4-2.6
2.6-2.8
3.0-3.2

I'm using KR808D-1's with 180mah and 280mah. Which one do I want and why?

As a rule of the lower the number the more vapor production and the vapor get warmer as you go lower on the ohms. Also the lower the ohms the quicker the battery discharges

Why would I want higher ohms?

The higher the ohms the higher the resistance which makes it hotter. The Ohms difference was put into cartos and atties to come up with the same affect of high voltage on a standard battery. But when the voltage got to high for some the lower ohm cartos were made to use so they didn't taste burnt on high voltage mods.

I would want the lower ohms with the KR808. The higher ohms might be best for a high-volt (5-6) device. The high ohms wouldn't make much power on the KR808.

Thanks, guys!

It's like a sliding scale 2.4 ohms = more vapor and less flavor, 3.2 ohms = less vapor and more flavor, but, 2.4 ohms drains batteries faster, uses juice faster and doesn't last as long, 3.2 will not drain your battery as fast, will use less juice and will last longer before dying. That's been my experience anyway.

So.... low ohms for low voltage or the other way around?

You guys have it backward. Lower ohms would be hotter and more battery drain. Think of it as a near short circuit. Imagine putting a solid wire in a wall outlet or across a battery post. Instant burn out. The lower the resistance the higher the amperage.

Ohm's Law: I = E/R
I is amperage (current)
E is voltage (your battery)
R is resistance (ohms)
For simplicity say your battery is 4 volts and your standard atomizer is 4 ohms. Low ohms atty is 2.
For simplicity:
4 volts divided by 4 ohms is 1 amp for standard atty.
4 volts divided by 2 ohms is 2 amps for low ohms atty
Obviously the lower ohm atty uses more amperage which means more battery drain and a hotter atty element.

Lower resistance- hotter, more vapor, less flavor, more battery drain
Higher resistance-cooler, less vapor, more flavor, less battery drain

Use any of those cartos, you'll be fine with your batteries.

Yes, Pure, I would use the lower ohms with the lower-voltage battery. Using lower ohms gives higher wattage, which makes up for less voltage. When you have more voltage in the battery, you get your power there and the higher ohms (more resistance) helps to keep the wattage in check. Too much wattage is not good. I think the good equation here is W=V2/R, where W is the power (watts) and V is voltage and R is the resistance (ohms). A 5-V battery with a 2.75-ohm atty gives you around 9.1 watts. A 3.7-volt battery with a 1.5-ohm atty gives you around 9.1 watts. The vaping from those 2 setups would be roughly, vaguely, kinda sorta the same.

 

[Pure Guava]

And can I assume, lower ohms = shorter atomizer life?

 

[bearscreek]

It "could," but I don't think I'd worry too much about it with the range of cartos you listed in the OP. Besides that, cartos are theoretically disposable (even though they might often last about as long as an atty anyway).
