The LAVATUBE is the pinnacle of innovation for VOLCANO eCigs and we are pleased to announce a few more additional features of the device. The LAVATUBE Version 2.5 now has variable wattage and is a wonderful addition to the already powerful variable voltage e-cigarette device. 

The new variable wattage function is easy to access and read on the already brilliant LCD screen. Take a look at how the new control panel works and how to access variable wattage on the LAVATUBE Version 2.5. 


LAVATUBE Version 2.5

Switching Between Voltage and Wattage Mode:

  1. Press and hold BOTH the plus and minus buttons at the same time for approximately 10 Seconds.
  2. The screen will change to either 3V or 3W depending on the current setting.
  3. Repeat to select a different mode.

Switching Between Average and VRMS Modes:

  1. Press and hold EITHER the negative or positive button for approximately 20-25 seconds.
  2. The screen will change to either NO1 (average voltage) or NO2 (vRMS) depending on the current setting.
  3. Repeat to select a dierent mode.

LAVATUBE Version 2.5

Average Voltage and VRMS Mode:

The initial setting on your LAVATUBE® v2.5 device will vary from Average Voltage to vRMS mode in
either variable voltage or variable wattage. When in Average Voltage mode (NO1) the
power going to the heating elements will be a little higher than in vRMS (NO2) mode. For this
reason we recommend only advanced users set the mode to (NO1). For a smoother, more consistent
vape, we recommend the device be set in (NO2) mode. For a hotter, more intense vape we recommend
setting the device in the (NO1) mode but suggest you use a lower voltage/wattage setting than normal.
This will help to prevent the heating element from burning out.

The differences between vAverage , and VRMS (no1 and no2 on the device), is simply put two different ways of reading an electric current from the e-cigarette. V average takes the average voltage from the range of voltage being provided and tells the ecig power control board (pcb) that voltage. This standard is mostly used in the USA, the rest of the world mostly uses vRMS.

vAverage Example:

Upon start up, within a micro second a range of something like 5-10 voltage readings, the average of that is approximately 4 volts (adding all and  dividing by the number of readings) so the PCB will interpret it as being provided 4v's instead of the range of 3v-4v it is actually getting. 

vRMS is different. It takes only the highest readings and takes the mean of those high readings, discarding the lowest readings. 

vRMS Example:

vRMS would read the same battery as 3.7v instead of 4v. This is because it took ONLY the mean number of the highest readings. This standard allows the battery to preform better for a longer time.

In Summary, vAverage takes all readings and averaging them out to provide the voltage reading. This pushes the battery to it's higher end. Were as vRMS, takes the higher numbers the battery is pushing, takes the mean of that and provides the voltage. This helps the battery preform longer and at a more relaxed pace.
