Geek Bar Pulse 15000 vs SEA XS 15000: Which One Is Right for You?

Same puff count. Same USB-C charging. Same 5% nicotine. On paper, the Geek Bar Pulse 15000 and the SEA XS 15000 look like near-identical options in the 15K puff disposable category. But once you hold them side by side, the differences become impossible to ignore — and they go well beyond which one has a fancier screen.

This comparison breaks down everything that actually matters: design, flavor selection, performance, battery, price, and the specific type of vaper each device is built for.

Design & form factor: two completely different philosophies

This is where the two devices diverge most dramatically — and where your personal preference will likely make the decision for you.

The Geek Bar Pulse 15000 is a box-style device. It's compact and well-balanced in the hand, but it's not something you'll forget is in your pocket. The full HD smart screen takes up nearly the entire front face, displaying your current mode, battery percentage, and e-liquid level in real time. Every puff triggers that iconic cosmic animation — and according to Geek Bar, the Pulse was the world's first disposable with a full-screen display, a claim that still holds up as one of its most defining features.

The SEA XS 15000 went in the exact opposite direction. At just 10mm wide, it's marketed as the world's slimmest disposable vape — thinner than most smartphones. It slides into your jeans like a pen and carries without any bulk whatsoever. There's no screen, no animations, no modes to switch — just a subtle LED indicator and a soft-touch matte finish that gives it a discreet, almost invisible daily-carry quality that the Pulse simply can't match.

Power modes: Regular vs Pulse (Geek Bar exclusive)

The dual-mode system is one of the Geek Bar Pulse's biggest advantages over the SEA XS and most competitors in the 15K puff category. A 3-position switch on the bottom controls everything:

The SEA XS has no equivalent to this. It operates in a single consistent mode from first puff to last — perfect for vapers who don't want to think about settings, but limiting for those who do.

E-liquid capacity: 16 mL vs 8 mL — the biggest technical gap

Both devices claim 15,000 puffs — but the Geek Bar Pulse achieves that with 16 mL of e-liquid, while the SEA XS does it with only 8 mL. That's a 2x difference in e-liquid volume for the exact same claimed puff count.

The Geek Bar Pulse's larger tank also keeps flavor consistent over a much longer real-world timeline. Dual mesh coils handle the 16 mL capacity without degrading, delivering the same quality hit past 14,000 puffs as on day one.

Flavor selection: 50+ vs 14

This category isn't even close. The Geek Bar Pulse 15000 — part of the broader Geek Bar Vapes lineup — offers one of the most extensive flavor libraries of any disposable on the market, across 8 themed editions: Planet, Zodiac, Frozen, Sour, Mintz, Thermal, Savers, and Zero Nicotine.

Real-world longevity: realistic usage estimates

Usage level	Geek Bar Pulse (Regular)	SEA XS 15000
Light (300–400 puffs/day)	5–6 weeks	2–3 weeks
Moderate (500–700 puffs/day)	3–4 weeks	1.5–2 weeks
Heavy (800–1,000+ puffs/day)	2–3 weeks	~1 week

The 16 mL vs 8 mL e-liquid difference is clearly reflected in real-world use. The Pulse consistently lasts roughly twice as long under comparable usage conditions — which directly affects how often you're spending money on replacements.

Final verdict
