Fuchai Duo-3 (2 Cover Version) 255W TC TCR Box Mod by Sigelei - GUNMETAL

The new Fuchai is here! For fans of the popular Fuchai 213 Plus and Fuchai 213 Mini, check out the new Fuchai Duo-3 255W TC TCR Box Mod by Sigelei.

The choice is yours. The Fuchai Duo-3 is a stylishly compact vape mod that has 2 options - dual battery mode and triple battery mode. This means that you can slim down your Fuchai Duo-3 by using only 2 batteries or vape with max power using 3 batteries (batteries sold separately). Either way, this mod pairs great with your favorite big tanks.

Featuring high wattage output and TC/TCR, this mod is designed for almost any build you can come up with. Its big fire button is easy to locate, even when vaping in the dark. With all of its great features, you've gotta try it - pick up a Duo-3 and enjoy vaping at its finest!

The Choice is Yours with Dual or Triple Battery Battery Options
The Fuchai Duo-3 2 Cover Version includes both the dual and triple battery covers. Since your battery door is part of the power current in your mod, your Duo-3 will automatically detect which battery mode you want to be in. Keep it slim in dual battery mode or max out to 255W with 3 batteries.

255/175 Watts of Power and Temperature Control/TCR
Compatible with resistance as low as 0.1 Ω, the Duo-3 can fire almost any build imaginable. With the dual battery cover on, you can vape up to 175 watts of power. With the triple battery cover, you can take it up to 255W! Temperature control and TCR modes allow you to customize your vape how you like.

Preheat Power/Time Settings
Customize your inhale with preheat settings. This means you can set your mod to preheat at a certain wattage for a set amount of time before it reaches your desired wattage.
