Sigelei Fuchai 200W styling and build quality

I must admit I have a bad habit of calling this mod the Sigelei Fuchsia so I had to go and look up what Fuchai means. Apparently there was a King Fuchai of Wu in China who reigned between 495-473 BC so it’s likely the device is named after him.

While this device has the same excellent build quality you might expect from Sigelei the first thought that does immediately spring to mind when you take it out of the box is “Has someone sat on it?” The reason being that the Fuchai is noticeably skewed and not as box like as other mods. Slightly rhomboid in shape would probably be the best way to describe it. It does take a little getting used to but I assume it is designed this way to cut down on the overall amount of bulk and in that respect it certainly succeeds. Another advantage is that it feels really good in the hand and due to the contoured design it does not press into your palm.

Premier Ecigs

The form factor despite the unusual aesthetics is seriously good and the Fuchai is much slimmer than typical dual 18650 devices. In fact it is so slim that you can actually put this device in the pocket of your jeans should you wish to carry it around with you! When fitted with batteries the Fuchai is not as heavy as many other dual 18650 mods due to the lightweight Zinc Alloy construction.

The 510 connector looks to be made from Stainless Steel and it has a copper contact for maximum conductivity. The pin is spring-loaded and I had no issues fitting atomizers to this device. All of them sat flush with no visible gap. The Fuchai has the same black rubberised finish as the 150W TC (ideal for Batman fans) and it makes for an excellent grip. The buttons are nicely done, having a satisfying “click” to them and they are completely rattle free.

The screen on this device is really nicely done being very bright and everything is clearer and much larger than previous Sigelei devices. The display shows Wattage/Temperature, coil resistance, battery life and also what mode you have the device set to: Power, Ni200 or Titanium. Voltage is not actually displayed unlike previous models.

Just like the Sigelei 150W TC the Fuchai does not have a Micro-USB Port which means you can’t upgrade the firmware. In many ways this is something of a con but to be fair I have never had any issues with the non-upgradeable 150W TC and I don’t honestly foresee any problems with this device. Unlike previous Sigelei devices the Fuchai does not use a YIHI chip and is fitted with an in-house chip designed by the manufacturer. Thankfully this time around Sigelei have added Titanium coil support but sadly there is no 316 Stainless Steel wire support.

The battery compartment is nicely done and I had no issues fitting the batteries. Just like the 75 Plus and the 150W TC this device has copper contacts. Battery removal is easy due to the included ribbon. The battery compartment door slides off easily, perhaps a little too easily in my opinion. However the magnets are actually quite strong and it is certainly not going to come off by itself. When you have the device in your hand the battery door does not wobble at all but I can’t say I am personally a massive fan of it and I would prefer it to be a little more secure.


There is an adequate amount of venting provided for via ten large holes in the base but considering the device has a maximum output of 200W I do feel there could be a little more ventilation.

Ease of use

The manual is well written and explains all of the Fuchai functions. I must admit it felt a bit strange to begin with because I am used to Sigelei’s typical YIHI chip menus. I often found myself switching this device off because with other Sigelei devices you press the fire button five times to go into the menu. One thing that is noticeable is the absence of Joule adjustment when using Temperature Control Mode. Strangely the Fuchai does not display Voltage either which is something of a first for a Sigelei device.

  • To switch the device on and off click the fire button five times.
  • To lock/unlock the device hold down the plus button then press the fire button.
  • To set Coil Resistance when using Temperature Control Mode hold down the minus button and the fire button simultaneously.
  • To switch between modes hold down the plus and minus buttons which will display the menu. Cycle between Power, Ni200 and Titanium with the plus and minus buttons before pressing the fire button to confirm your selection.

Sigelei Fuchai 200W performance

To test Wattage Mode with this device I used my GP Heron 1.5 and my Achilles II RDA. I encountered no problems at all and the device gave me a great vape!


To test the Temperature Control Functionality I used my Freemax Scylla which is currently fitted with a Ni200 coil. Initially when vaping this tank on the Fuchai I found that the vape did feel noticeably cooler and I had to increase the temperature since I couldn’t fine tune my vape via the usual Joules setting. I usually vape my Freemax Scylla with a Ni200 coil at 240°C but with the Fuchai I found myself setting the temperature to 270-280°C to get a comparable vape. However I think what happened was that either I did not set the resistance properly or the tank was not completely screwed on to the device. It could also have been the coil because after replacing that and filling my tank with a different E-Liquid I got my typical vape at 240°C and encountered no further issues.

Despite the absence of the Joules adjustment the Fuchai seems to work well in Temperature Control Mode. It may bother some people who really like to tweak their vape but I don’t see it as a big deal providing the device is achieving the desired temperature consistently and it seemed to be doing that well. I think it’s fair to say that with the Fuchai Sigelei have streamlined a lot of the menu functions which in some ways is a good thing because it makes this device far more approachable for new vapers. Battery life was very typical for a dual 18650 device.


In my opinion the Fuchai is a decent mod that is good looking and nice to use. Despite the noticeable change regarding Temperature Control adjustment the device works very well in that mode. The lack of upgradeable firmware may be an issue for some and I do think it is something Sigelei should start taking seriously since its absence may deter quite a few potential customers. The battery door could also be a little more secure than it is. The absence of Stainless Steel coil support might also be another issue for some users. The question really is how much these slight negatives bother you.

I cannot fault the Fuchai’s performance and it will certainly give you a very good vape! Another plus point is that the device does have the typical quality construction you would expect from a Sigelei device and it feels very solid and durable!

Pure Eliquids

If you are really in love with this device’s looks and form factor then rest assured it is certainly a very worthwhile buy but I would advise you to be mindful of the fact that the Sigelei 200W TC and Sigelei 213 are coming very soon.
