Fuchai Duo 3 Overview

This mod measures 85mm x 42mm x 33mm, smaller than previous Fuchai devices such as the Sigelei Fuchai 213 Plus. The device is constructed from zinc alloy to make it durable and ergonomic. The body features a beautiful design with soft contours allowing comfortable hand holding. Ventilation holes on the bottom keep the device cool, while a top-located 510 connection bezel with a springloaded pin ensures flush installs of any build or tank. You can get the device in black, silver, grey, red, blue, or gold.

You will find a large 1-inch full-color TFT display on the control face. The menu looks similar to its predecessors but has been reorganized, displaying mod stats vertically. The screen below a bright Fuchai logo shows indicators for resistance, voltage, current mode, current temperature/wattage, amperage, battery voltage for each cell, a battery bar, and a puff counter. The entire control face looks great, with the display and oversized firing button meeting at a slanted angle to further enhance the modern design. Below the screen, there are also a micro USB port and two small round mod adjustment buttons.

A brand new chipset, developed by Sigelei, can be found inside the Fuchai Duo-3 Box Mod. This chip allows for a maximum output of 175 watts (dual batteries) or 255 watts (triple batteries), a low resistance capability of 0.1ohm, and a temperature output of 212 to 572 degrees Fahrenheit. The unit is built with standard modes such as power mode, three temperature control modes (for nickel, titanium, and stainless steel), and TCR mode for precise resistance settings for your particular coil. But, what sets this mod apart from the crowd is the TFR mode (Temperature Factor of Resistivity) that permits it to work with hybrid builds. Firmware upgrade capability via the micro USB port means this mod will stay current with the latest vape technologies in the marketplace. And, to ensure vaping is as safe as possible, the unit is made with reverse polarity protection, low resistance protection, low voltage alert, overheat protection, and short circuit protection.

The Fuchai Duo-3 mod utilizes two 18650 external batteries that can be charged via the micro USB port on the control face with the included cable. Balanced charging technology ensures the batteries are always safe to use, and charging occurs at a lightning-fast 2.5A, so your cells will be topped off in no time. If you prefer to use your charger, the cells are easily accessed via a convenient battery cover on the back held in place by a lock switch that is easy to operate.

Overall, the Sigelei Duo-3 mod features an amazing design, an incredible display and comes with all the technical bells and whistles you could need. And it’s affordable!
