The Sigelei Fuchai Duo-3 175W/255W TC comes in a neat black box. Sigelei has been obsessed with the Fuchai series, and the Duo is the third addition to the team. It is quite similar in design with the Fuchai-series mods like the GLO 230W or the original Fuchai 213W Black. However, the duo features a removable back-flip battery lid, while the traditional models have sliding lids.

Overview

There is also a lot of fine-tuning in the chipset, and the new Sigelei Fuchai Duo-3 175W/255W TC comes powered with the holy trinity of cloud chasing; Temperature Control, Wattage Control, and TCR modes. The “3” in the nomenclature of the product is not a version but the fact that it can be transformed into a 3-battery mod like the Wismec Reuleaux RX GEN3, IJOY Captain X3 or the Tesla 3. Honestly, somehow this is a useless feature as you won’t be getting more power but simply a longer battery life.

Since these are removable batteries, connected in series, replacing the drained batteries with charged ones won’t be an issue. However, if anyone is traveling for long hours and have less time to worry about changing the batteries, then the 3-battery-powered mods can be a friend indeed. Nevertheless, battery life won’t be an issue with the Sigelei Fuchai Duo-3 175W/255W TC, as you have space for two 18650 batteries that can easily pack up 6000 mAh of power. The mod has a 1 Inch vertical display, which packs a lot of information into a tiny little space.

The nice thing about this Sigelei mod is that it features a multi-colored display, where the different units and symbols are color-coded, and it gives a nice premium appeal to the device. The Sigelei Fuchai Duo-3 uses the standard Sigelei button operations and is quite easy to use. Five clicks on the fire button turn the device on/off. The menu can be accessed with 3 clicks on the fire button where you can rotate between various parameters. Clicking the fire button and the up button takes you to the pre-heat options, where you can set your wattage and your timer. The fire button and the down button combo is for locking your buttons, where you can also access the stealth mode. Pressing down the up and the down key at the same time lets you play with the resistance in Temperature Control mode.

What comes with the Sigelei Fuchai Duo-3 175W/255W TC kit?

The Sigelei Fuchai Duo-3 175W/255W TC comes in a black cardboard box, with Styrofoam layers on the inside. Inside the package, you will find a Sigelei Fuchai Duo-3 Box Mod, a three-battery cover, a user manual and a micro USB cable.

Being a mod-only kit, you won’t be getting any tank with the device. You also won’t get any battery with the mod.

The Sigelei Fuchai Duo-3 175W/255W TC is fine vaping at its very best

The Sigelei Fuchai Duo-3 175W/255W TC is a vaping jewel and can transform your everyday vaping juice into epics cloudbursts. Most mods in this price range flaunt its TC and power mode, but the Sigelei Fuchai Duo-3 175W/255W TC is a tad above the average. It is very sensitive to temperature control and uses an innovative temperature compensation mode to slowly take the temperature up to the desired level. The latter ensures a firm control over the vapor and lets you play around with varying temperature and resistance in the TCR mode.

Being a Sigelei product, the mod is designed thoughtfully to the last detail and incorporates the coveted preheat feature, which allows to ramp up or ramp down your vapor. This gives good control over the vapor in Power mode as you can slowly withdraw power in small tranches. This makes sure that you have a consistent vapor quality all throughout, with minimum battery use. The Sigelei Fuchai Duo-3 175W/255W TC is a mod-only kit and they don’t deliver any tanks with the device. The best part of this device is that the 510 plughole is placed at the very center of the top-side of the mod. This creates a beautiful symmetry around the edges and leaves you enough room to experiment with larger sized RTAs. The Sigelei Fuchai Duo-3 175W/255W TC can accommodate tanks up to 32mm in size. The feature ensures a nice touch of versatility to the device as it is possible to easily fit in the high-end RTAs for a more refined and prolonged vaping experience.

What are the best mods for the Sigelei Fuchai Duo-3 175W/255W TC?

The Sigelei Fuchai Duo-3 175W/255W TC is a versatile mod when it comes to choosing your tank. It supports Ni, Ti, and SS 316/17. You can fit any 510-tank within 32mm diameter. Some of our recommendations would be the Aromamizer Plus, the Omega Beast, Sense Blazer, the Wismec Reux, the Eleaf Melo 300 or the Tank V3 from Scottua.

    How do I lock this device so that the power will quit changing? I like it about 100 watts and it seems to be all to often that I go to hit it and realize it’s power has went sky high 200+watts?
