The RAZ LTX DC25000 and the Geek Bar Pulse X 25K are the two best-selling 25,000-puff smart disposables in the United States. Both hit the same headline spec — 25K puffs in standard mode, 15K in boost — but they're engineered very differently and they aim at different vapers. This comparison puts them side-by-side on every spec, breaks down price-per-puff, maps flavor libraries against each other, and ends with a clear 2026 verdict.
Quick Verdict
Pick the RAZ LTX DC25000: Wider flavor library (40+ vs ~25), lower cost-per-puff ($0.00076 vs $0.00108), genuine leather grip, dedicated Zero Nicotine edition, and a slightly smaller build that pockets easier. Best daily driver for flavor variety.
Pick the Geek Bar Pulse X 25K: Bigger 18 mL tank (vs 16 mL), faster charging (80% in 20 minutes), award-winning 3D curved LED display, dual-core VPU processor, and Meteor/Slush/Jam/Thermal limited editions that dominate social media. Best if you prioritize hardware tech and short charging cycles.
At-a-Glance Comparison
Both devices are manufactured by Geekvape under different brand lines — RAZ is the premium/leather lineage, Geek Bar is the flagship consumer brand. That shared DNA means they draw similarly (smooth, dual-mesh-coil feel) but diverge on hardware features, tank size, flavor strategy, and build materials.

Power Modes & Vaping Performance
Both devices offer two modes, but they execute the "boost" differently.
RAZ LTX — Regular vs Boost
Regular Mode (12W): single mesh coil fires at 12 watts. Cooler, smoother vapor. Full 25,000-puff lifespan.
Boost Mode (24W): both dual mesh coils fire simultaneously at 24W. Warmer, denser vapor, stronger flavor pop. Cuts to 15K puffs.
Toggle via side button. HD screen confirms active mode with a Sun/Moon icon for light/dark display theme.
Pulse X — Regular vs Pulse
Regular Mode: dual-core VPU processor alternates between the two mesh coils. Designed to preserve flavor consistency even at low battery. Full 25,000-puff lifespan.
Pulse Mode: both coils fire together under VPU control — Geek Bar claims 200% vapor output over the original Pulse 15K. 15K puffs.
Toggle via base switch (which also serves as airflow control and power-off).
Display, Build Quality & Design
This is the biggest hardware difference between the two devices.
The Geek Bar Pulse X 25K ships the world's first 3D curved LED display on a disposable — it wraps around the device body with a starry-sky constellation animation, and it won a Gold Award at the 2024 London Design Awards. If you care about how your vape looks, this is the winner. The Thermal Edition adds a color-changing heat-sensitive shell. The Meteor, Slush, Jam, and Platinum editions each have their own shell finishes. It is the most visually distinctive disposable currently on the market.
The RAZ LTX DC25000 goes a different direction. The Mega HD screen is a flat animated display — functional, not flashy — but it's the only disposable with a light/dark mode toggle for the screen, which genuinely helps battery life and reduces eye strain at night. The signature feature is the genuine leather grip accent. It changes how the device feels in hand — closer to a mid-tier mod than a disposable. Less visually loud than the Pulse X, but more premium-feeling.

Frequently Asked Questions
Are the RAZ LTX 25K and Geek Bar Pulse X 25K made by the same company?
Yes. Both are manufactured by Geekvape. Geek Bar is Geekvape's flagship consumer brand; RAZ is the premium sub-brand aimed at variety and build quality. That shared DNA is why both devices draw similarly and use dual mesh coil systems — but they're tuned differently and target different vapers.
Which lasts longer: RAZ LTX or Pulse X?
Identical puff ratings. Both deliver 25,000 puffs in Regular Mode and 15,000 puffs in Boost/Pulse Mode. Real-world lifespan depends on draw length and mode usage — expect 10-20% less than rated for both. At 150 puffs/day in Regular Mode, either device lasts around 5.5 months.
Which has better flavor?
Subjective, but: the Pulse X's dual-core VPU processor keeps flavor more consistent in the last 25% of the tank. The RAZ LTX's Boost Mode produces warmer vapor that better suits candy, dessert, tobacco, and cinnamon flavors. Neither is objectively "better" — the RAZ LTX has more flavors to choose from, so it's more likely to have a profile you'll love.
Is the RAZ LTX cheaper than the Pulse X?
Yes, significantly. At JellyPuffs pricing, the RAZ LTX is $18.99 and the Pulse X is $26.99. Per puff, the RAZ LTX costs $0.00076 vs $0.00108 for the Pulse X — about 30% cheaper. Over a year of average use, the Pulse X costs roughly $17 more.
Which charges faster?
The Geek Bar Pulse X 25K wins by a wide margin. Its quick-charge system hits 80% capacity in 20 minutes via USB-C. The RAZ LTX takes 45-60 minutes for a full charge. Both use USB-C; neither includes a cable in the box.
Do both have Zero Nicotine options?
Yes, but not equally. The RAZ LTX has a dedicated Zero Nicotine edition with 5 flavors: Razzle Dazzle, New York Mint, Bangin Sour Berries, Blueberry Watermelon, and Strawberry Burst. The Pulse X offers 0 mg variants on select flavors (Blue Rancher, Miami Mint, Strawberry B-Burst, and rotating picks) but not as a dedicated edition.
Can I ship either to Texas?
Yes — both ship from JellyPuffs's Texas warehouse. JellyPuffs only stocks devices that meet applicable state requirements where relevant. For the full compliance picture under Texas SB 2024, read our Texas SB 2024 vape law explainer.
Which is better for beginners?
The Pulse X has a slight edge for beginners because the base switch doubles as airflow and mode control — simpler to learn. But both are draw-activated, both display battery and e-liquid levels clearly, and both ship ready to vape out of the box. If price matters more than learning curve, the RAZ LTX is still the smarter pick.
Final Verdict
Both devices are excellent. The Geek Bar Pulse X 25K wins on hardware — bigger tank, faster charging, more striking display, slightly smoother late-tank flavor thanks to the VPU processor. The RAZ LTX DC25000 wins on variety and value — 40+ flavors, dedicated Zero Nicotine edition, 30% cheaper per puff, and a leather-grip build that feels more premium in hand.
For most daily-driver vapers at JellyPuffs, the RAZ LTX DC25000 is the smarter buy: you get more flavor choices, better long-term economics, and the same 25,000-puff lifespan. The Pulse X earns its premium if you specifically want the 3D curved display aesthetic, the Slush/Jam/Thermal edition flavors, or the 20-minute fast-charge. For everything else, the RAZ LTX is the stronger value play.
Shop both devices at JellyPuffs — 100% authentic, Texas-compliant where applicable, same-day shipping on orders before 2 PM CT. No ID hassle at door, discreet packaging, and 24-hour processing.
