The WISMEC Reuleaux series has long been a benchmark for high-performance, multi-battery mods. Known for their robust power output and distinctive triangular design, they’ve captivated vapers seeking reliability and advanced features. Now, WISMEC introduces the Reuleaux GEN3, promising a significant evolution in both form and function. This latest iteration aims to refine the series, offering a more compact, ergonomic, and user-friendly experience without sacrificing the power and reliability its predecessors were celebrated for. We’ve spent considerable time with the GEN3, and here’s our comprehensive take on whether it lives up to the Reuleaux legacy.
Resistance Range: 0.05-1.5ohm for TC modes, 0.1-3.5ohm for VW mode
Temperature Range: 100-315°C/200-600°F
Cell Type: 3 x high-rate 18650 cells (discharge current should be above 25A)
Screen: 1.3-inch OLED
Max Charging Current: 2A
Design and Build Quality
The most striking change in the GEN3 is its size. WISMEC has managed to shrink the device significantly, making it one of the most compact triple-18650 mods on the market at its release. It fits much more comfortably in the hand compared to previous Reuleaux models, a welcome improvement for portability and everyday use. The aesthetic maintains the signature Reuleaux triangular profile, but with smoother, more rounded edges.
The zinc alloy chassis feels solid and premium, exhibiting excellent build quality typical of WISMEC. The large 1.3-inch OLED screen is bright and clear, providing all essential information at a glance. The fire button is responsive, and the adjustment buttons offer a satisfying click. The battery door is sturdy and secures the three 18650 cells firmly.
Performance
Powered by WISMEC’s advanced chipset, the Reuleaux GEN3 delivers consistent and reliable performance across all modes. In Variable Wattage (VW) mode, the mod fires instantly and accurately up to its impressive 300W maximum. While 300W might be overkill for most vapers, the headroom ensures excellent power delivery even at lower wattages, leading to a stable and satisfying vape.
Temperature Control (TC) mode, supporting Ni, Ti, SS, and TCR, also performs commendably. We found the temperature regulation to be smooth and consistent, preventing dry hits effectively. The 2A fast charging capability is a convenient addition, though external charging is always recommended for multi-battery devices. The battery life, with three 18650 cells, is exceptional, easily lasting a full day or more for average to heavy vapers, even at higher wattages.
Final Thoughts
The WISMEC Reuleaux GEN3 is a triumph in evolution for the Reuleaux series. WISMEC successfully addressed the size concerns of previous models while retaining and even enhancing the robust performance expected from a triple-18650 device. Its compact form factor, combined with a powerful and accurate chipset, makes it a highly versatile and appealing option for vapers who demand both high wattage and extended battery life in a portable package. While 300W might be more than most need, the efficient power delivery and excellent build quality solidify its position as a top-tier mod.
