NEXA is a disposable vape brand developed by VOOPOO — one of the most technically capable manufacturers in the vaping industry. The lineup currently spans five device formats: NEXA Ultra II 50K, PIX 35K, Flex 35K, Pro 30K, and the Ultra InvisaCloud Edition. Each one targets a different vaping priority, but they all share two engineering features you won't find on most competitors: the transparent Crystal Tank for real-time e-liquid monitoring and the Juicy Lock sealed activation system that keeps the wick fresh until first use.
This guide covers every NEXA device, their specifications, the full NEXA flavor lineup, pricing, and how they stack up against brands like RAZ and Foger.
NEXA Vape Product Lineup
NEXA structures its product line around three tiers: the flagship Ultra series for maximum puff count, the mid-range PIX for portability, and the Flex series for users who want a swappable pod system. Here's what each device brings to the table.
NEXA Ultra II 50K
The highest-capacity NEXA device. 50,000 puffs in Normal mode, 30,000 in Turbo. Features a 3D curved screen, dual 0.9Ω mesh coils, and the full Crystal Tank + Juicy Lock package. The 20mL e-liquid capacity is among the largest in the disposable category.
NEXA PIX 35K
The pocket-friendly option. 35,000 puffs Normal / 20,000 Turbo. HD mini display, adjustable airflow, and a sealed Juicy Lock activation that prevents flavor degradation during storage. Smaller than the Ultra but still packs 16mL of e-liquid.
NEXA Flex 35K
NEXA's swappable pod system. Buy the 1200mAh battery once, then swap pre-filled pods — up to 40,000 puffs per pod in Normal mode. Available in Standard and Coolness Edition with 4-level adjustable cooling. 3D curved screen and dual power modes included.
NEXA Pro 30K
Built for vapor output. Up to 30,000 puffs with quad mesh coil configuration and a large 3.2" HD screen. Dual/quad power modes let you push cloud production without switching devices. The largest display in the NEXA lineup.
NEXA Ultra InvisaCloud Edition
Same 50,000-puff hardware as the Ultra II, but with cloud-free vapor output for discreet use. Limited to 5 exclusive flavors. Ideal for situations where visible vapor clouds aren't an option.
NEXA Vape Specifications Comparison
Side-by-side specs across the full NEXA lineup. Puff counts listed are for Normal mode — Turbo/Boost modes reduce count by roughly 30–40% in exchange for denser vapor.

NEXA Vape Technology
NEXA differentiates itself from the competition through two proprietary systems that address the biggest pain points of disposable vapes: stale flavor and blind e-liquid monitoring.
Crystal Tank
The transparent e-liquid tank lets you see exactly how much juice remains — no guessing, no relying on a screen estimate. VOOPOO claims this design also reduces cotton residuals by improving e-liquid saturation, which translates to roughly 35% better e-liquid utilization compared to traditional opaque tank designs. Available on the Ultra II and PIX models.
Juicy Lock System
In a standard disposable, the cotton wick sits soaked in e-liquid from the moment it leaves the factory. By the time it reaches your hands — potentially weeks or months later — oxidation has already degraded the nicotine and muted the flavor. Juicy Lock uses a sealed, press-to-activate tank that only wets the wick when you first use the device. The result: your first puff actually tastes like it should.
Dual Mesh Coils
All current NEXA devices use mesh coil technology. The Ultra II and PIX run dual mesh configurations, while the Pro 30K pushes it further with quad mesh. Mesh coils heat e-liquid more evenly than traditional round-wire coils, which reduces hot spots and delivers more consistent flavor across the full lifespan of the device.
NEXA Vape Flavors
NEXA currently offers 30+ flavors spread across its device lineup. The Ultra II 50K and PIX 35K share most of the same flavor menu, while the Flex series adds some exclusive options including the Coolness Edition pods. The InvisaCloud Edition has its own limited set of 5 flavors.
Top-selling NEXA flavors across all devices include:
- Blue Razz Ice — sweet blue raspberry with a clean menthol finish
- Miami Mint — a smooth, full-bodied mint that avoids the synthetic edge
- Strawberry Banana — classic smoothie profile, balanced sweet and creamy
- Fcuking Fab — NEXA's signature mystery fruit blend, one of their most talked-about flavors
- Sour Apple Ice — tart green apple with icy exhale, strong all-day-vape candidate
For the complete flavor list with taste profiles and our ranked recommendations, see the full NEXA Vape Flavors Guide.
NEXA Vape Price
NEXA sits in the mid-to-premium tier of disposable pricing, but the cost-per-puff ratio is competitive — especially on the Ultra II 50K, which delivers more puffs per dollar than most 25K or 35K competitors.
| Device | Retail Price | VOS Price | Puffs | Cost per 1,000 Puffs |
|---|---|---|---|---|
| Ultra II 50K | $32.99 | $23.99 | 50,000 | $0.48 |
| PIX 35K | $28.99 | $22.99 | 35,000 | $0.66 |

How to Use a NEXA Vape
All NEXA disposable vapes are draw-activated with no power button required for basic operation. Here's the quick-start process:
- Charge the device — plug in via USB-C until the screen shows full battery. First charge takes about 60–80 minutes.
- Activate Juicy Lock (Ultra II & PIX) — press the sealed tank to activate the e-liquid flow into the wick. You'll hear a faint click.
- Inhale — draw from the mouthpiece. The device auto-fires and the screen displays battery level and puff count.
- Adjust settings — use the side button to switch between Normal and Turbo modes. Slide the bottom lever to adjust airflow (tighter = MTL, looser = DTL).
For the Flex series, attach the pod to the battery unit first — the magnetic connection locks it into place. Swap pods when you notice weakened flavor or see the Crystal Tank is empty.
For full troubleshooting (blinking lights, E4 error codes, charging issues), see our NEXA Vape Instructions & Troubleshooting Guide. For pod replacement details, see the NEXA Vape Refill Guide.
NEXA Vape vs Competitors
How does NEXA stack up against other high-puff brands available at VapesOnlineShop?
| Feature | NEXA Ultra II 50K | RAZ RX 50K | Foger Switch Pro |
|---|---|---|---|
| Puffs | 50,000 | 50,000 | 30,000 (per pod) |
| Transparent Tank | ✅ Crystal Tank | — | — |
| Sealed Activation | ✅ Juicy Lock | — | — |
| Flavor Count | 30+ | 100+ | 28 |
| Pod Swappable | Flex only | VUE 50K only | ✅ All models |
| Parent Brand | VOOPOO | RAZ (independent) | Foger (independent) |
NEXA's strongest differentiator is the Crystal Tank + Juicy Lock combination — no other brand in this price range offers both. RAZ wins on sheer flavor variety with 100+ options, and Foger's magnetic pod system is more seamless for repeat purchases. For a head-to-head analysis, see our NEXA vs RAZ Vape Comparison.

Frequently Asked Questions
Is NEXA Vape made by VOOPOO?
Yes. NEXA is a sub-brand of VOOPOO, one of the largest vape manufacturers globally. VOOPOO is known for the DRAG series of advanced mods and has applied its engineering expertise to the NEXA disposable line. This means NEXA benefits from VOOPOO's established supply chain, quality control processes, and R&D capabilities.
Can you refill a NEXA Vape?
No. All NEXA devices are closed-system disposables — the e-liquid tanks are sealed and not designed to be opened or refilled. For the Flex series, you replace the entire pre-filled pod when it's empty (not refill it with liquid). See our NEXA Vape Refill Guide for full details on pod replacement.
How long does a NEXA Vape last?
It depends on the model and your usage pattern. The Ultra II 50K delivers up to 50,000 puffs in Normal mode — for an average user taking 300–400 puffs per day, that's roughly 4–5 months. The PIX 35K lasts about 3 months at the same rate. Turbo mode reduces lifespan by 30–40% but increases vapor density and flavor intensity.
What is the best NEXA Vape flavor?
Based on sales data and user reviews, the most popular NEXA flavors are Blue Razz Ice, Miami Mint, and Strawberry Banana. Fcuking Fab — a mystery fruit blend — is NEXA's most unique offering and consistently generates strong word-of-mouth. For our full flavor rankings, see the NEXA Flavors Guide.
Are NEXA Vapes safe?
NEXA products contain nicotine, which is an addictive chemical. Like all disposable vapes, they are intended for adult smokers and vapers only and are not risk-free. NEXA devices use food-grade e-liquid ingredients (VG, PG, nicotine salt, food-grade flavorings) and do not contain vitamin E acetate, diacetyl, THC, or tar. For a full ingredient breakdown, see our NEXA Vape Ingredients page.
What nicotine strength does NEXA use?
All current NEXA devices use 5% (50mg/mL) nicotine salt. This is the standard strength for US-market disposable vapes. Nicotine salt delivers faster absorption and a smoother throat hit compared to freebase nicotine at the same concentration. NEXA does not currently offer zero-nicotine or lower-strength options.
Which NEXA device should I choose?
It depends on your priority. If you want maximum longevity and the freshest flavor, go with the Ultra II 50K — it has Juicy Lock and the largest capacity. If portability matters more, the PIX 35K is smaller and pocket-friendly. If you want to save money long-term by reusing the battery, the Flex 35K pod system is the most economical. And if you need discreet, cloud-free vapor, the InvisaCloud Edition is the only option on the market that delivers it at this puff count.
Are the NEXA products on VapesOnlineShop authentic?
Yes. VapesOnlineShop is an authorized distributor of NEXA products. Every device is sourced directly through verified supply channels and inspected before shipping from our Memphis, TN warehouse. NEXA devices include an authenticity verification code that you can check on the official NEXA website.
