The NEXA FLEX is a rechargeable pod vape designed to blur the line between disposables and pod systems. It offers two interchangeable pod styles — the Visible Pod (up to 40,000 puffs) and the Cool Pod (up to 30,000 puffs). Each pod comes prefilled with 18 mL of e-liquid at 5% nicotine.
Powering the FLEX is a 1200 mAh battery, rechargeable via USB-C, and paired with a high-tech UI chip and curved 3D screen. Instead of tossing the whole thing when the juice runs out, you just swap the pod. It’s practical and adaptable, which sets the stage for everything else this device offers.

2. Flavors
The NEXA FLEX lineup splits into two categories — Cool Pods and Visible Pods — with some overlap but also a few exclusives. Across both, you’ll find a mix of fruit-heavy profiles, classic staples, and some more adventurous blends.
Here’s the full flavor lineup for each pod type, with detailed notes on the ones we were able to try firsthand.
Cool Pod Flavors
-
- Watermelon Ice – Clean and refreshing, this one leans natural rather than syrupy. The sweetness is light, and the cooling turns it into something closer to an iced watermelon juice than a candy flavor. Smooth, crisp, and easy to vape all day. 4/5
- Black Dragon – A bold mix that lands somewhere between grape and blue raspberry. It has that sweet-tart edge of blue razz layered over darker, juicier berry notes, giving it more depth than the usual fruit ice. 5/5
- Blue Razz Ice
- Strawberry Ice
- Sour Apple Ice
- Pink n Blue
Visible Pod Flavors
- Strawberry Banana – A creamy, balanced blend where the banana adds body without drowning out the strawberry. The result is sweet but not cloying, with a smooth finish that makes it one of the more satisfying dessert-style options. 5/5
- Sour Apple Ice – Tart, yet sweet green apple hits right out of the gate, with a crisp bite that stays bright through the exhale. The cooling cuts the sour edge, leaving a clean and refreshing aftertaste. 5/5
- Blue Razz Ice
- Strawberry Ice
- Dragon Melon
- Tobacco
- Fcuking Fab
- Pepper Mint
- Pink n Blue
- Clear
- Cherry Bomb
3. Design and Quality
The NEXA FLEX is built around a 3D curved screen that looks and feels modern. It’s bright, responsive, and tracks each puff in real time. By default, the screen shows a circuit-style animation, but you can hold the lower button for three seconds to switch into a darker, discreet mode. That same button also toggles between Normal and Turbo with a single click.
The body is built from durable PC/PCTG plastic, solid but still lightweight. Design-wise, it has a vertical split — the battery side houses the 3D screen and branding band, the other side is there for the Cool Pod or Visible Pod to slot into. The Visible Pods are transparent, making it easy to keep an eye on juice levels, while the Cool Pods are solid and opaque. Beyond their different functions, this contrast makes it easy to tell the pods apart at a glance. Both slot into the battery cleanly with a firm, snap-in fit.
The upper round button controls the 4-level cooling adjustment when using a Cool Pod — just tap to cycle through off, 1, 2, or 3. At the base of the device you’ll find the airflow slider and USB-C charging port.
3.1 Does the NEXA FLEX leak?
With 18 mL pods, leakage would be a disaster. Fortunately, the pod seals are tight and reliable. In testing, there was no gurgling, no seepage around the mouthpiece, and no sticky residue even after carrying in a pocket for several days.
3.2 Durability
The device feels sturdy for a reusable unit. The shell doesn’t flex under pressure, and the pod lock clicks firmly into place with no wiggle. Dropping it from chest height caused no damage or impact on performance. The magent connecting the pod to the battery is strong enough, not to send the pod flying when dropped but still easy to pull apart when you want to make a flavor swap.
The curved screen is especially impressive – despite being glossy, it barely shows scratches, even after rough handling or pocket carry.
3.3 Ergonomics
At 28.5 × 51.9 × 99.5 mm (about 1.1 × 2.0 × 3.9 inches), the NEXA FLEX is on the larger side compared to compact disposables, but the rounded edges and curved front make it comfortable to hold.
Thanks to the even weight distribution between the battery and pod, the FLEX sits comfortably in your hand without a lopsided pull one way or the other. And the duckbill-style mouthpiece is perfectly curved for your mouth.
4. Battery and Charging
The NEXA FLEX’s 1200 mAh battery is double or even triple the size of what you get in most disposables. On a full charge, it holds up impressively well – around 9 to 10 hours of heavy-vaping in Normal mode and closer to 7 hours in Turbo. The curved screen keeps you updated with real-time battery readouts, so there’s no guessing or surprise shut-offs.
Charging is quick, too. While a full charge takes only about 30 minutes, even a short 10-minute top-up gives you a few solid hours of vaping. USB-C and pass-through support mean you can keep it plugged in and still use it, which is handy if you forget to charge overnight.
5. Performance
The NEXA FLEX is built around its Smart Match and Adjust platform, which automatically fine-tunes output depending on which pod you’re using. That means both the Visible Pod and the Cool Pod deliver steady flavor and vapor without dry hits, but each pod brings its own personality.
- Visible Pod – Designed for longer sessions, it offers up to 40,000 puffs in Normal mode or 25,000 in Turbo. Normal mode leans toward efficiency, with smoother, cooler vapor, while Turbo kicks up power for denser hits and bigger clouds at the cost of shorter lifespan.
- Cool Pod – Slightly lower capacity at 30,000 in Normal or 18,000 in Turbo, but adds a unique twist: the 4-level cooling adjustment (off, 1,2,3). This button at the top of the screen lets you cycle between different intensities of coolness from a faint freshness to an ice-cold blast. It’s a real differentiator and gives each flavor multiple personalities depending on your setting.
Draw activation is highly sensitive. Pair that with the adjustable airflow slider on the base, and you can fine-tune the draw anywhere from a super-tight pull to a wide-open, airy lung hit. The range here is bigger than most pod systems, and the flexibility makes it easy to find a sweet spot.
At 50 mg nicotine, the throat hit is firm and satisfying. In Normal mode it stays smooth and steady, while Turbo adds extra punch. Vapor production is dense for a pod-based device, giving satisfying clouds without ever feeling over the top. Combined with the cooling adjustment, it makes the FLEX adaptable to different seasons, moods, and personal preferences in a way most disposables can’t match.
6. Price
For everything it offers, the NEXA FLEX is shockingly affordable. Retailing between $11 and $17, it costs less than many smaller disposables yet delivers far more in both capacity and features. A starter kit comes with the Smart Device and one 18 mL pod, and pod packs are sold separately in larger quantities for extended use.
When you factor in the flavor quality, adjustable cooling, dual pod options, and huge puff counts (18,000–40,000 depending on mode), the value becomes even clearer. Cost per puff is dramatically lower than most disposables, and the reusable device means you’re not throwing money away on full replacements.
7. Verdict
The NEXA FLEX isn’t trying to be just another high-puff disposable — it’s built as a reusable platform that gives you more control, more variety, and a lot more value. Between the Visible Pods with their massive 40K puff capacity and the Cool Pods with adjustable cooling, you’re not locked into a single style of vape. Add in the Normal and Turbo modes, the wide-ranging airflow slider, and the sensitive auto-draw, and you’ve got a device that adapts to whatever kind of session you want.
The build quality is solid, the screen is genuinely useful without being over the top, and the pods fit securely with no leaks or fuss. Battery life is strong enough to handle heavy use, and the quick-charge setup means you’re rarely stuck waiting. Most importantly, the flavor quality across the pods holds up, staying bold and consistent even with the massive puff counts.
And then there’s the price. At $11–17, the FLEX undercuts many smaller disposables while delivering far more in capacity, flexibility, and longevity. Because the device itself is reusable, you’re saving money while cutting down on waste.
If you’re looking for something simple and cheap, there are plenty of disposables that will get the job done. But if you want big capacity, customizable performance, and premium flavor without paying a premium price, the NEXA FLEX hits the mark.
