Ohms calculator

[MarineVapor]

Not sure if I'm using the calculator right. I'm trying to figure out what wattage I should use with a .2 ohm coil.

Crank it up in steps, starting low and gradually stepping up until you hit the sweet spot, only your taste buds can tell you that, it is either zingidigity, the beezneez, or, you go to far over and have to step it back down.

I agree with @IMFire3605 just start at one wattage and keep increasing until you get the vape you like...unless it's a mech mod then you're doing it wrong.

I'm using a kanger sub box minI with a max output of 50 watts is that enough?

It all comes down to a few things, Ohm's of your coil, the viscosity of your juice and the density of your wick, just about all are different, just increase the wattage incrementally till you find the sweet spot.

I have 24G kanthal and the bacon cotton. I was thinking of trying a dual coil but my box won't fire at all

KBOX Mini (aka Subbox Mini) FEATURES:

• Dimensions: 3-1/4"L x 1-1/2"W x 7/8"D
• 510 Threaded
• Minimum Resistance: 0.3 ohm
• Adjustable wattage settings: 7 to 50 watts using 0.1 watt increments
• Zinc alloy casing
• On/off - press the power button 5 times within 3 seconds to turn the device on or off
• Low voltage protection
• Low resistance protection
• Short circuit protection
• Reverse battery protection
• Low battery warning
• 10 second cut off safety feature
• More lightweight and compact compared to the original KBOX
• Magnet battery cover - Utilizes one high amp 18650 battery (removable and sold separately)
• Charged via USB (USB Cable included). You can keep your 1850 battery within the unit as you charge - Provides Pass Through Capabilities (meaning you can vape while it charges)

Highlighted in red above, your mod can't fire a 0.2ohm coil. To get near a 0.3minimum (24awg, 2.5mm inner diameter = 8top/7bottom wrap, 24awg, 3.0mm ID = 7top/6bottom wraps (heat flux coefficient for both of these configs 158 mW/mm²)) for dual coils. I'd actually go with a 0.4ohm, (24awg, 2.5mm ID = 10top/9bottom wraps, 24awg, 3.0mm ID = 9top/8bottom wraps (heat flux coefficient at 50watts 138 mW/mm² for both of these with 24awg)) for dual coils
And for better efficiency - 26awg, 3.0mm ID 0.4ohm = 6top/5bottom wraps each coil, giving a heat flux coefficient of 194 mW/mm² at 35 watts
To reach the heat flux of the 26awg, the 24awg needs more power in the 60 to 75watts range
