15 watts maximum power output
Wheel adjustable voltage dial
Improved battery life 2 x 's avg. , we have a new controller that is MUCH more efficeint. avg. 15 hrs per charge
New finish , blasted finish with no knurling , it will improve the slip factor !
Uses same batteries as the original Infinity 14430 , and charger so no need to buy new batts etc.
3-3 to 5.5 volt adjustment
New top cap design for a sleeker look.
Over current Protection
Over temp. protection
Reverse Battery protection
Size 4.75" long x .72" 18mm around
The Lavatube uses small push buttons (3) 1.on/off 2.+(plus) 3.-(minus) for adjustment 3v to 6v in 1v increments and a larger single fire button on the side, has a flush mount 510 connection. Uses (1) 18650 batt.

Selectable voltage from 3v to 6v in 0.1v increments
Power on/Off Button - hold the button down for 5 seconds to turn the device on, hold the button again for 5 seconds to turn the device off.
+ Button: On press, increases voltage by .1 increments between 3volt and 6 volt. When you reach 6 volts, the user starts back at 3 volts
- Button: On press, decreases voltage by .1 increments between 3volt and 6 volt. When you reach 3 volts, the user starts back at 6 volts
+ and – Button: Press and hold both buttons for five second to disable the + and – button, locking the device on the voltage it is currently set at.
Regulated output which keeps the voltage the same with each puff - regardless of the remaining battery power. As the battery drains, the device will keep the voltage consistent.
If the activation button is held down for 10 seconds or longer, the LAVATUBE will shut itself off until the button is released. To prevent overheating the atomizer and the device.
Short Circuit/Atomizer Protection. The LAVATUBE can recognize an atomizer with too low of a resistance for the current voltage setting and will drop the voltage to 3.7v to protect both the battery and atomizer. If the atomizer is too low or shorted out it will shut off power to the device to protect the LAVATUBE from being damaged.
Reverse Battery Protection – Protects the device in case you put the battery in the device backwards
Battery Monitoring/Over-Discharge Protection – The device will monitor the battery voltage and automatically turn off when the battery is discharged, preventing damage to the battery by overly depleting it.
Battery Voltage Meter. The LAVATUBE has a voltage meter built in, simply press the red power button 7 times and it will display the voltage of the battery for a few seconds. This way you can monitor the power left in the battery before it needs to be recharged. 18650 batteries provide 4.2v at peak charge and over the life of the battery that voltage will decrease to about 3.3v level before needing to be recharged. This will help you monitor the life cycle of the battery. The LCD screen will flash when the battery needs to be recharged, and will stop powering the device.
Amperage Limiting to 2.5 amps – The device should monitor and shut itself off if it detects any excessive over-current conditions.
Vent hole on the bottom of the device for added safety
