The SBX 25K Disposable Vape enters the market with a spec sheet that genuinely stands out: three distinct power modes (Eco at 15W, Boost at 20W, X Mode at 25W), adjustable airflow spanning MTL to DTL, a full-color display, 20 mL of e-liquid, and 14 flavors. But what most reviews gloss over — and what every serious buyer deserves to understand — is what Metatine actually is, what it isn't, and why that distinction matters before you buy.
This is the complete breakdown: the hardware, each of the three modes in practice, all 14 SBX vape flavors reviewed, honest context on Metatine, and a clear verdict on who this device is built for.
What is Metatine? An honest explanation
Before diving into modes, airflow, and flavors — Metatine is the most important thing to understand about this device, and it deserves a straight answer.
With that context clearly established: the SBX 25K is a well-engineered device that delivers on its hardware promises. Whether or not Metatine is the right formula for you is a personal decision — but it should be an informed one.

Eco, Boost & X Mode — three sessions from one device
The three-mode system is the SBX 25K's most practical feature — and the puff count differences between them are significant enough to genuinely shape how you use the device day to day.
Mode strategy: Start your pod in Eco or Boost and save X Mode for moments when you want intensity — an evening session, a specific flavor you want to push. Using X Mode exclusively will burn through a 25,000-puff device in roughly the same time as a 17,000-puff device. Eco for the day, X for the occasion.
Three-position adjustable airflow: MTL, Normal, DTL
The SBX 25K's airflow system is more than a marketing checkbox — with three meaningfully distinct positions, it genuinely changes the character of every draw. Combined with the three power modes, you have nine different experience combinations from a single device.
The combination of MTL airflow at Eco Mode closely mirrors the sensation of a traditional cigarette — a tight draw, strong throat hit, and smooth flavor delivery. At the other end: DTL airflow at X Mode is a genuinely powerful hit that produces dense, satisfying clouds. The SBX 25K covers both extremes and everything in between, making it one of the most versatile sealed disposables currently available.
Brilliant color display & 1,000 mAh battery
The full-color display is one of the SBX 25K's most immediately impressive features. Unlike standard LED indicators or basic single-color screens, this is a vivid, high-contrast color display that shows your current power mode, real-time battery percentage, and e-liquid level simultaneously. It activates on every draw and stays readable in both indoor and outdoor light.
The 1,000 mAh integrated battery is sized appropriately for the 20 mL tank — large enough that the battery and e-liquid deplete at a compatible rate rather than one running out long before the other. USB-C charging keeps recharge cycles short, and the display gives advance warning before the battery runs critically low mid-session.
The SBX 25K was developed in collaboration with Charlie's Chalk Dust, a highly respected US e-liquid house known for complex, layered flavor profiles. That partnership is reflected in the flavor quality — these aren't generic fills, and the dual mesh coil's consistent heat distribution across all three modes keeps every profile vivid from the first draw to the last.
All 14 SBX vape flavors reviewed
The SBX 25K's 14-flavor lineup spans fruit, ice, mint, candy, tobacco, and clear — with a notable emphasis on bold, distinctive profiles over generic category fillers. The Charlie's Chalk Dust collaboration shows most clearly here.
First-time SBX buyer? Start with Lemon Apple Ice or Confetti to experience what the Charlie's Chalk Dust collaboration brings to the lineup. Ex-smokers should go straight to Virginia Tobacco — it's one of the most accurate tobacco profiles in the sealed disposable category. Mint fans: Sweet Spearmint over Cool Mint for complexity.
Real-world longevity by mode
Puff counts change significantly between modes. Here's what to expect per device at moderate draw lengths, broken down by power setting:
Most vapers who use all three modes throughout the day will land somewhere between the Boost and X Mode estimates. The 1,000 mAh battery lasts approximately one to two days between USB-C charges at moderate use — and the 20 mL e-liquid tank is sized to outlast multiple charging cycles before the pod runs dry.
Pros & cons
- Three distinct power modes (15W / 20W / 25W) with real performance differences between them
- Three-position airflow (MTL / Normal / DTL) — nine total experience combinations
- Full-color display showing mode, battery %, and e-liquid level simultaneously
- Charlie's Chalk Dust collaboration — flavor quality clearly above the disposable average
- Virginia Tobacco — one of the most accurate tobacco profiles in the 25K category
- 20 mL e-liquid — generous capacity for the price point
- 1,000 mAh battery with USB-C — solid endurance and fast recharge
- Draw-activated simplicity despite the advanced feature set
- Metatine regulatory status varies by state — not available everywhere
- Long-term safety data on Metatine is still limited — buyers should be aware
- X Mode cuts the puff count to 17,000 — a significant reduction from the 25K headline
- 14 flavors is a smaller selection than some 25K competitors
- Slightly bulkier than slim-profile disposables — less pocket-friendly
Final verdict
The SBX 25K is one of the most capable and customizable sealed disposables available right now — three power modes, three airflow settings, a color display, 20 mL of Charlie's Chalk Dust-developed e-liquid, and 14 genuinely well-crafted flavors at a competitive price. If Metatine is available in your state and you're comfortable with its profile (read the explainer above before buying), this device delivers a level of personalization that most competitors in this puff count tier simply can't match.
The combination of Eco Mode at MTL airflow for all-day flavor sessions and X Mode at DTL for evening intensity makes the SBX 25K one device that genuinely serves multiple vaping styles. For vapers who feel boxed in by single-mode, fixed-airflow disposables — this is the obvious upgrade.
WARNING: The SBX 25K contains Metatine™ (5% / 50mg), a synthetic nicotine analogue that may be addictive. This product is intended for adult vapers 21+ only. Not for use by pregnant or lactating women, or individuals with pre-existing medical conditions without physician consultation. Regulatory availability varies by state — check local laws before purchasing.
