Low-resistance atomizers and cartomizers are popular among people who own electronic cigarettes with batteries that operate at 3.7 volts and have no way to vary their power levels. While a regular 2.5 ohm atomizer and 3.7 volt battery produce 5.4 watts of power, using a low-resistance 1.5 ohm atomizer with the same battery results in an increased power level of 9.12 watts — more vapor, better taste. However, this only applies to “dumb” electronic cigarettes with no protective circuitry. The Lavatube electronic cigarette is different.
The Lavatube has an automatic over-current protection circuit that kicks the voltage back to 3.7 volts when the output current is over 2.5 amps. This never becomes a concern when you use high-resistance atomizers and cartomizers. For example, a 3.0 ohm atomizer operating at 6 volts produces a current of just two amps — nowhere near the current needed to engage the protection circuit. However, a low-resistance 1.5 ohm atomizer at the same voltage generates a current of 4 amps. Although you may set the Lavatube electronic cigarette to 6 volts, it will detect the resistance of the atomizer when you press the fire button and force the power level down to 3.7 volts. You then lose the benefit of using a variable-voltage electronic cigarette.
Although you can use a low-resistance atomizer or cartomizer with the Lavatube electronic cigarette safely at 3.9 or 4.0 volts without tripping the protection circuit, you will be far better off using a high-resistance atomizer or cartomizer as this gives you full access to all of the Lavatube’s voltage settings. The Lavatube produces the most flavorful, satisfying vapor when it operates at 6 volts.
