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
