Sigelei Fuchai 213 Plus vs Wismec Reuleaux RX GEN3 Dual: Full Comparison, Specs & Verdict
Looking for a budget-friendly dual-battery box mod? Two of the most popular picks are the Sigelei Fuchai 213 Plus and the Wismec Reuleaux RX GEN3 Dual. Both run on two 18650 cells, both offer 200W+ output, and both include full temperature control. They are close in price and capability — so which should you choose? Here’s the breakdown.
Quick Verdict
Both are dependable dual-battery mods, but they target slightly different users. The Wismec Reuleaux RX GEN3 Dual wins on raw power (230W) and a much larger 1.3-inch color screen. The Sigelei Fuchai 213 Plus counters with a lighter, simpler chassis and a fast preheat. Pick the Wismec if you want maximum headroom and a big, bright display; pick the Sigelei if you prefer a lighter mod with a cleaner interface.

Design and Build Quality
The Sigelei has a slim, curved aluminum body with a contrasting trim that keeps weight down and fits easily in the hand. The Wismec keeps the rounded, organic Reuleaux shape — bolder and more distinctive, but slightly heavier and more of a “statement” piece. Both have a secure battery door and a comfortable grip; between the two, the Sigelei is the more subtle and pocket-friendly, while the Wismec is the more eye-catching.
Performance and Features
Power delivery is steady on both. The Sigelei pairs a 213W ceiling with a fast preheat for a quicker, more satisfying ramp-up, and its 35A max output gives plenty of headroom for sub-ohm builds. The Wismec pushes a little further to 230W, which gives even more room for demanding tanks, and its larger screen makes it easier to read at a glance. Both support full temperature control across Ni200, Titanium, and Stainless Steel with TCR adjustment, so experienced users get precise control either way.
Battery and Charging
Both run on two external 18650 cells and charge via Micro-USB at 2A. Neither is as fast as a modern Type-C mod, and for battery longevity a dedicated external charger is recommended on both. The Wismec’s quick charge is marginally quicker to top up, but the difference is minor. With two cells, both easily cover a full day of moderate-to-heavy vaping.
Design and Build Quality
Both mods are well made, and the difference is mainly a matter of taste. The Sigelei is slim and understated, with a curved aluminum body and a quiet look that disappears in your pocket. The Wismec is bolder, with the rounded Reuleaux silhouette that is unmistakably a Wismec device. Both have a secure battery door and a comfortable grip, and both feel like they will survive regular use.
Battery and Charging
Each uses a pair of external 18650 cells, so both need a dedicated charger for best results. On-board charging is a convenience, not a mainstay, on either device. With two cells, a full day of moderate-to-heavy vaping is realistic, and neither mod drains unevenly. Whichever you choose, battery performance is a non-issue.
The Bottom Line
At the end of the day, both are excellent value dual-battery mods and neither will let you down. The Wismec is the stronger pick if you want the most wattage and the biggest, brightest screen. The Sigelei is the stronger pick if you want a lighter, simpler, more pocket-friendly mod. Buy the one whose feel and interface you prefer, and you will be happy.
Wattage and Real-World Power
In practice, the difference between 213W and 230W rarely matters — almost no tank needs more than 150W. What does matter is how the mod delivers that power, and both are steady and predictable here. The Sigelei’s fast preheat gives a slightly quicker ramp-up, while the Wismec’s bigger screen makes it easier to see and adjust your settings while you vape.
Ease of Use
Both have a learning curve if you dive into temperature control, but in wattage mode they are simple enough. The Sigelei is arguably a touch more intuitive thanks to its cleaner menu, while the Wismec’s larger display makes its menus easier to read even if there are more options to scroll through.
Which One to Buy
For a lighter, simpler, more pocketable mod, choose the Sigelei Fuchai 213 Plus. For maximum power and a big, bright screen, choose the Wismec Reuleaux RX GEN3 Dual. Both are dependable, both are great value, and you will not go wrong with either.
Build Quality and Durability
Both mods are built to last. The Sigelei’s aluminum body is light but reassuringly solid, and the Wismec’s chassis is sturdy enough for daily carry. Neither has flimsy panels or rattling buttons, and both will comfortably handle the occasional drop. For a device you use every day, that confidence matters.
Final Verdict
If you want a lighter, simpler mod with a quick preheat, the Sigelei Fuchai 213 Plus is the pick. If you want maximum wattage and the biggest, brightest screen, the Wismec Reuleaux RX GEN3 Dual wins. Both are dependable, great-value dual-battery mods that will serve you well for years.
When you weigh the two, remember that both are excellent value and that neither is a poor choice. The deciding factors are a bigger screen and a little more wattage on the Wismec, versus a lighter body and a faster preheat on the Sigelei. Trust your preferences on those two points and you will land on the right device.
Whichever you choose, make the most of it by pairing the mod with a quality sub-ohm tank or rebuildable and a reputable battery. A good 18650 cell and a well-made atomizer are the two things that will make either of these mods shine, turning a capable device into a genuinely enjoyable daily driver. Get those right, and any concerns about the older interface or the slightly dated charging port will quickly fade into the background. Whether you lean toward the lighter Sigelei or the bigger-screened Wismec, you are getting a solid, dependable dual-battery mod that represents excellent value for money.
Which Should You Buy?
- Buy the Sigelei Fuchai 213 Plus if you want a lighter, simpler mod, a fast preheat, and a clean interface — and you don’t need more than 213W.
- Buy the Wismec Reuleaux RX GEN3 Dual if you want maximum wattage (230W) and a big, bright 1.3-inch color screen.
Honestly, for most vapers either is a great value — the differences are about feel and screen size more than raw capability. If you run high-power sub-ohm tanks and want the biggest display, go Wismec. If you want something lighter and easier to pocket without giving up real power, go Sigelei.
