The photo above shows the Geek Bar Pulse 15K, Pulse X 25K, and iPhone 17 side by side, providing a clear size comparison between the two devices.
The Pulse 15K focuses on a compact and practical design. Measuring approximately 82.6mm × 52.6mm × 27.7mm, it feels solid in the hand while remaining easy to carry. Its full HD smart screen displays key information such as battery and e-liquid levels, while the textured outer design and smoother, durable body give the device a distinctive look and feel.
The Pulse X 25K keeps the same design style but features a larger, more refined design. With a bigger body of approximately 91.6mm × 57.4mm × 29mm, it feels more substantial in the hand. The biggest visual upgrade is the 3D curved screen with Star UI, offering a more interactive smart-device experience.
From a design perspective, the Pulse 15K is the more portable option, while the Pulse X 25K delivers a more advanced display experience.
Geek Bar Pulse Vape Flavors: Similar Dual Mesh, Enhanced Flavor Delivery on Pulse X
Both the Geek Bar Pulse 15K and Geek Bar Pulse X 25K feature Dual Mesh Coil technology, delivering smooth vapor production and consistent flavor performance.
The Geek Bar Pulse 15K already performs well in flavor quality. During testing, classic Geek Bar Pulse X flavors such as Blue Razz Ice, Watermelon Ice, and Frozen Blackberry Fab showed good balance between sweetness, cooling, and smoothness. The flavors feel clean and enjoyable, making it a strong choice for everyday vaping.
The Geek Bar Pulse X 25K enhances flavor delivery by combining Dual Mesh Coil design with the VPU technology, Dual Core architecture, and improved Pulse Mode performance. Compared with the Pulse 15K, the Pulse X produces denser vapor, a warmer inhale, and a more intense flavor profile. Geek Bar Pulse flavors like Blue Rancher, Lemon Heads, and Sour Fcuking Fab highlight this difference with richer sweetness and a more layered flavor experience.
Overall, the Pulse 15K focuses on smooth and balanced flavor, while the Pulse X 25K delivers a richer and more powerful vaping experience. The main difference is not the flavor profiles themselves, but how each device delivers those flavors — with the Pulse X offering stronger intensity, denser vapor, and a more powerful output.
Performance: Dual Modes, Smarter Power Adjustment
Both the Geek Bar Pulse 15K and Pulse X 25K feature dual modes, with a three-position switch located at the bottom of the device. Vapers can switch between Regular Mode and Pulse Mode to experience different levels of power output, airflow, vapor production, and flavor intensity.
The Geek Bar Pulse 15K uses dual-core control technology. In Regular Mode, the two mesh coils work alternately, helping maintain consistent flavor even as the battery level decreases. When switched to Pulse Mode, the device delivers enhanced airflow and a 20W output, producing denser vapor and a stronger flavor experience. The trade-off is higher battery and e-liquid consumption, resulting in fewer puffs.
The Geek Bar Pulse X 25K upgrades the experience with AI Power Adjustment technology, which optimizes the balance between airflow and power output through a one-button adjustment system. Combined with its larger 820mAh battery and upgraded VPU technology, the Pulse X provides stronger vapor production, more intense flavor, and a more refined vaping experience.
For vapers who prefer simplicity, portability, and balanced performance, the Pulse 15K remains a practical choice. However, the Pulse X 25K is better suited for vapers looking for stronger output, longer endurance, and upgraded smart features.
How to Charge Geek Bar Pulse 15K and Pulse X 25K?
Both the Geek Bar Pulse vapes use USB-C rechargeable batteries, but the Pulse X 25K introduces a larger battery capacity and improved charging performance for longer vaping sessions.
The Geek Bar Pulse 15K is equipped with a 650mAh rechargeable battery, which is designed to support its 15,000-puff capacity in Regular Mode and 7,500 puffs in Pulse Mode. It supports USB-C charging for convenient daily use, with a full charge taking approximately 45 minutes. However, frequent use of Pulse Mode can consume battery power faster due to its higher power output.
The Geek Bar Pulse X 25K upgrades to an 820mAh battery, helping support its higher puff count and stronger performance output. The Pulse X 25K vape can also reach approximately 80% charge in around 20 minutes through USB-C fast charging.
