Joyetech Cuboid TC 150/200W Box Mod Instructions

***This device can be a 200W device if you do the most current firmware update: See below for more info.***


The Cuboid TC 150W is another extraordinary vaping device created by Joyetech as a great addition to their already outstanding mod line. This notable box mod features a vertical OLED display inspired by its predecessor. Its brains lie in the cutting-edge chipset from Joyetech that allows for temp controlled vaping at up to 150 watts of power output. This combined with an ergonomically shaped device and a sleek, polished look—the Cuboid TC 150W would make the perfect addition to any vaping collection.

The Cuboid TC 150W is constructed from high-quality zinc alloy, making for a device that is both lightweight yet extremely corrosion-resistant and durable. The Cuboid TC 150W is rectangular in shape, but has gliding smooth edges and a silky, refined finish for a comfortable fit in the user’s hand. The front of the device is furnished with a large rounded metal activation button with the opposite side sporting the micro USB connection port.

Turning your attention to the body of the Cuboid TC 150W you will find the HD OLED vertical display, which is placed above the rounded rectangular “+” and “-“ adjustment button of the device. This crystal clear screen displays a plethora of important information for the user like current mode setting, remaining battery life, wattage setting, atomizer resistance and even the amount of amps the atomizer is pulling from the battery used. A unique feature that makes certain that the user will always stay on the safe side of their battery’s capabilities.

The Cuboid TC 150W is backed by a technologically advanced operating chip from Joyetech. This incredible chipset gives the Cuboid its power capacity of up to 150 watts in VW mode and four impressive temperature control modes for the ideal temp controlled vape completely suited to the needs of the user. The temp controlled modes the Cuboid TC 150W is equipped with are VT-Ni for Nickel builds, VT-Ti for Titanium coils, VT-SS316 to use with Stainless Steel coils and also TCR mode. Using these modes, the temperature range of the device can be set from 212 - 662°F / 100 - 350°C for a vape with robust flavor and vapor production and one that is free from burnt tasting dry hits.

The Cuboid’s TCR mode is one of the things that makes this device quite special, TCR mode allows the user to manually adjust the TCR values for different types of wire to further improve on the accuracy of the mod’s ability to limit and sense an atomizer coil’s temperature.

The Cuboid TC 150W is powered by dual 18650 batteries, which are easily accessed through the metal battery cover located at the bottom of the device. When a new pair of batteries isn’t available for a fast switch, the device can also be charged via the USB port with the included USB charger.

**The Cuboid TC 150W Box Mod’s firmware is now currently upgradeable using Joyetech’s VT Software in order to bring its power capacity up to 200W. Upgrade your device here.
