The resistance value, expressed in ohms, is an important point to consider. A lower resistance value generates higher heat and increases the throat hit, vapor temperature, and vapor production.
You can achieve maximum vapor temperature by choosing a low-resistance coil. However, in this case, you should remember the following:
Your battery will drain faster.
You will produce more vapor but consume more liquid.
Your coil will clog and wear out faster.
Therefore, be careful not to choose too low a resistance value to avoid a burnt taste due to rapid liquid evaporation.
In summary, resistance values based on battery voltage are:
1.5 Ω: 3.3V - 4.2V battery
1.8 Ω: 3.6V - 4.5V battery
2.2 Ω: 3.7V - 4.8V battery
2.5 Ω: 4.2V - 5.5V battery
2.8 Ω: 4.4V - 6V battery
The output voltage of fixed-voltage batteries like Evod and eGo is 3.7V. Therefore, you should choose a resistance value between 1.5 and 2.2 ohms.
If you have a variable voltage battery, the resistance value is less critical. You can adjust your battery's power by changing the voltage. If the resistance is too low, you can decrease the voltage. If the resistance is too high, you can increase the voltage.
Concept of Power:
Simply put, if you decrease the resistance (ohms) and increase the voltage, you get more power.
Power formula: P = U²/R
Example: Your atomizer has a resistance (R) of 1.8ohm and your battery voltage (U) is 3.8V. In this case, P = (3.8 x 3.8)/1.8 = 8 watts.
Experts have defined the optimal range as 8W - 12W.
