Here's an article about calculating wattage with a 0.4 ohm resistance:

Understanding Watts and Ohms in Vaping

When it comes to vaping, understanding watts and ohms is crucial for a safe and enjoyable experience.

  • Watts (W) represent the power output of your vape device, determining how much heat is generated to vaporize your e-liquid. Higher wattage generally results in larger clouds and a more intense flavor.
  • Ohms (Ω) measure the resistance of your coil, which impacts the amount of current flowing through it. Lower resistance (like 0.4 ohms) means more current will flow, leading to higher wattage.

Calculating Wattage: Ohm's Law

To figure out how many watts your vape produces at 0.4 ohms, we need Ohm's Law:

W = V² / R


  • W is the power in Watts
  • V is the voltage
  • R is the resistance in Ohms

The problem is, we need the voltage! The voltage is determined by your vape mod's settings. Let's look at some common scenarios:

Example 1: 3.7 Volts

If your vape mod is set to 3.7 Volts, here's how to calculate wattage:

  • W = (3.7)² / 0.4
  • W = 13.69 / 0.4
  • W = 34.225 Watts

Example 2: 4.2 Volts

If your vape mod is set to 4.2 Volts:

  • W = (4.2)² / 0.4
  • W = 17.64 / 0.4
  • W = 44.1 Watts

Safety Considerations

  • Higher wattage can produce more heat. Make sure your coil is designed to handle the wattage you're using.
  • Battery safety is paramount. Always use batteries with a high enough continuous discharge rate (CDR) for your wattage and coil resistance.
  • Experiment gradually. Start with lower wattage and gradually increase it to find your sweet spot.

Remember: Always consult your vape mod's manual for specific recommendations and safety guidelines.
