Confusing the Sigelei Fuchai V2 with the original would be an honest mistake, but a dreadful one. They are so different. One is a high-output box mod; the other is a moderate-output tube mod. One features temperature adjustment; the other automatically adjusts temperature.

The Fuchai operates at up to 200 watts; the Sigelei Fuchai VW is only meant to operate at 40W or less. There is a sporty, vivid red version of the Fuchai box mod while the Fuchai V2 is all stainless steel. Receiving V1 when you meant to buy a V2 or vice versa would be quite a shock.

The Sigelei Fuchai V2

While the Fuchai 200W uses two 18650 batteries, Version Two contains a built-in 1100-mah cell but still operates at sub ohms. Hit a low point of 0.15 ohms: pretty good for a device with 1/5th the wattage output capacity of a Fuchai 200W (capable of 0.05 ohms when functioning as Temperature Control device).

Kanthal coils are built into the covered atomizer which makes this unit resemble a Joye eGo One only wider by several mm diameter. Airflow control built into the tank portion creates flexibility when you draw: play around to find a style that’s just airy enough for your vaping method.

Compatible Threading for an Odd Size

A 510-threaded well and atomizer enable these to sit perfectly together but 510 threading also lends the two pieces of a Fuchai V2 kit flexibility. Then again, how many 19-mm tanks and batteries are there to choose from?

The Eleaf iJust and D16 aren’t the right size. A Joye eGo One is too small. An Amigo 2200-mAh battery measures 19 mm. So does a Taifun GS V2 RTA. With a little searching you could probably find a few more, but what’s the point? Sigelei’s Fuchai V2 parts were designed for each other, so don’t split them up.

Wattage Range

Choose output that suits your e juice and mood: 20W to 40W created by the resistance of your selected coil. Opt for 0.15 to 0.6 ohms. Ni200 coils allow you to reach the lowest resistance level and the Fuchai V2 does everything else automatically.

Constant Temperature Technology (CTT) by Sigelei prevents dry hits from your atomizer too. Two Ni200 coils rated 0.2 ohms are included with your set. All the customer does is press a button on this slick, silver pen-style APV.

Other Features of the Sigelei Fuchai V2 Kit

A 3.8-inch Sigelei Fuchai V2 comes ready to use with a battery, atomizer tank, drip tip, those two coils, and a charging cord. The tank, covered with but a narrow window into the e juice well, shows you how far the liquid level has dropped.

Just be sure to have some suitable e juice around like King’s Crown or Charlie Noble; something that whips up a lot of vapor and makes your high-tech system worth the effort. This mod is tiny at 3.8 inches without the drip tip.

Although the V2 is wider than an eGo One and a little oddly sized, its light weight (under 50g) and short profile make it compact and easy to carry around; easier than a Fuchai 200W (which is also compact given what it can do). 304 Stainless Steel provides durability and non-corroding threads without becoming heavy in your pocket. The price ($27 or so) will also leave your mood light.
