Tesla Two Sub Mod 4000mAh Box Mod Instructions.



Another incredible release from Tesla, the Tesla Two Sub Mod is a sleek and compact, yet powerful box mod built around two internal batteries for an incredible battery capacity of 4000mAh. Quite an exceptional device, the Tesla Two Sub Mod is the perfect unregulated box mod for intermediate and advanced vapers alike.

The Tesla Two Sub Mod has been completely redesigned from the Tesla One Sub Mod, instead of having the conventional tube mechanical mod shape; Tesla upgraded their device to the increasingly popular box shape. This shape also allowed for Tesla to add two internal batteries for a whopping 4000mAh of power for an all day vape with barely a dip in its performance. The maximum power output of this device is an astonishing 100 watts.

Functionality is important, but so are looks and Tesla took that into account with their redesigned look for the Tesla Two Sub Mod. Built from high-quality aluminum makes for a lightweight yet sturdy device. The Tesla Two features a sleek anodized aluminum coating available in Black, Blue, Gunmetal Gray and Pink for an elegant and captivating look. Sometimes box shaped objects can become a little cumbersome when held, to get around this feel, Tesla rounded the edges of the Tesla Two for an ergonomic feel in the palm. This simple design allows for comfortable all day vaping.

The Tesla Two features a spring-loaded silver plated copper positive pin for excellent conductivity that self adjusts for a secure connection with any RBA or tank that is used. With a contact that is made out of copper, one of the most conductive materials available translates to incredible performance when the box mod is used.

The Tesla Two Sub Mod is one of the few box mod devices that are unregulated in design, this means it performs in a similar function to unregulated tube-shaped mechanical mods. There is no internal chip that regulates the power of the device. When fully charged the Tesla Two Sub Mod has maximum voltage output of 4.2 volts and will go down as the battery is depleted. When a charge is needed, the device can be charged with any standard micro-USB cable (not included) and can be plugged into the USB outlet of any computer.

Tesla did not want to leave the power capacity as a guessing game and so they added a unique feature to assist users. The Tesla Two is equipped with an LED Light Display indicator that surrounds the silver activation button. When the voltage of the device is between 4.2 – 3.7 volts, the LED will continue to flash BLUE whenever the device is used. When the power depletes below 3.7 – 3.2 volts, the LED will flash RED. If the voltage goes below 3.2 volts, as an added safety feature the LED light will flash 15 times in RED, then the device itself will no longer function and will automatically power down. Another great feature that is built in is the Overheat protection, if a user vapes over 10 seconds, the LED light will flash 8 times and will automatically cut power to the atomizer being used.

Tesla did not stop there with their ingenious design of the Tesla Two Sub Mod—this device also has other convenient safety features built into it as well. This incredible device includes Low Voltage Protection, Short Circuit Protection, Over-voltage Protection and Over-current Protection.

Turning the Tesla 2 On/Off:

The Tesla has a On/ Off feature. This will allow you to lock the fire button so there are no accidental button presses when the device is in your pocket. 

To Unlock

  • Press the Fire button 5 times fast. 
  • The Color LED ring around the Fire button will blink 3 times
    Red if the Power is: 3.2v- 3.7v
    Blue if the Power is: 3.7v- 4.2v

To Lock 

  • Press the Fire button 5 times fast.
  • The color LED ring around the Fire button will flash 3 times


Charging The Teslas 2:

The color LED ring around the Fire button will light up different colors during the charge life of the battery. 

When the button is pressed:

  • Blue
    If the battery is between 4.2v and 3.7v

  • Red 
    If the battery is between 3.7v and 3.2v

When the battery reaches 3.2v the LED color ring will blink Red 15 times letting you know it is time to charge the battery. Once you have reached this point the device will power down and not allow you to vape on it till you recharge the battery. 


To charge the battery simply plug the micro USB end of the charging cable into the charge port on the bottom of the device, and plug the USB end of the charging cord into any standard USB outlet. 

Once connected to a power source the red and blue LED lights in the color ring will blink at the same time, 3 times. 

When disconnecting the device from the power source the LED lights will blink 6 times. 

Once the device is fully charged, the LED color ring will blink 20 times in Blue only, once fully charged and then the light will go out. 


10 Second Cutoff: 

The Tesla 2 has a 10 second cutoff timer on it, meaning if you hold the Fire button down for more than 10 seconds the LED color ring will blink 8 times then shut off. It will stop supplying power to the heating element at that time. 

Once you reach the Cutoff you will need to release the Fire button and wait a second before you can press the button again and continue to vape. 


Short Circuit Protection:

If the device senses a Short or an atomizer reading below 0.1ohm, the LED color ring will blink 5 times Red and then shut down. 



You are now ready to enjoy your Tesla 2 Box Mod.
