RAZ RX 50K Review — 50,000 Puffs of Pure Endurance

What the RX 50K Brings to the Table

Before the RX 50K, the biggest RAZ device was the RYL Classic 35K with 16.5mL of juice. The RX jumps to 19mL — a 15% increase — while adding a third power mode (Super Boost) and the most granular airflow control in the lineup at 9 discrete levels. It's the first RAZ disposable that genuinely competes with refillable pod systems on feature count, without requiring you to fill, coil, or maintain anything.

The "Dew Edition" branding signals that the RX 50K runs a completely different flavor strategy from other RAZ devices. Instead of the familiar roster of fruit and ice profiles, you get five "Code" flavors inspired by citrus soda — fizzy, beverage-style profiles that don't overlap with any existing RAZ flavor. If you've been vaping Miami Mint and Blue Raz Ice across the TN9000 and LTX 25K, the RX 50K is designed to be a different experience entirely, not a replacement.

Full Specifications

Three Power Modes — Tested

The RX 50K is the only RAZ device with three distinct power settings, toggled by a button at the base of the device.

Normal Mode is the endurance setting. Lower wattage, cooler vapor, longer draw times before the coil heats up. This is where the 50,000-puff figure comes from. Flavor intensity is moderate — the soda fizz notes come through clearly, but the cooling finish is dialed back. For background vaping through a workday, Normal stretches the device as far as it'll go.

Boost Mode raises power and vapor density. The throat hit sharpens, fruit and citrus notes intensify, and the fizzy quality in the Dew Edition profiles becomes more pronounced. Puff count drops to approximately 25,000 — still substantial. This is the mode most users will settle into for regular use. It hits the balance between flavor strength and device longevity.

Super Boost Mode pushes maximum wattage for the thickest vapor and strongest throat hit the RX 50K can deliver. Cherry notes in Code Red and the tartness in Code Pink become noticeably more forward. The tradeoff is aggressive: puff count falls to approximately 20,000, and battery drain accelerates. Super Boost is situational — good for a few intense draws, but not practical as a daily setting unless you're willing to sacrifice over half your puff count.

In testing, switching between modes mid-session was seamless. The 3D screen updates the current mode in real time, and there's no warm-up delay between transitions. The 9-level airflow works independently of power mode, so you can pair tight airflow with Super Boost for an intense MTL hit, or wide airflow with Normal for a looser, cooler draw.

9-Level Airflow — Does It Matter?

Most disposables give you zero airflow control. Some offer a toggle between two settings. The RX 50K gives you nine. At level 1, the draw is tight — true mouth-to-lung resistance that mimics a traditional cigarette. At level 9, it opens up to a loose, almost direct-lung draw with significantly more vapor volume.

The practical range for most users sits between levels 3 and 6. Below level 3, the draw gets restrictive enough that Super Boost mode can feel like you're fighting the device. Above level 6, Normal Mode starts producing wispy vapor. The sweet spot depends on which power mode you pair it with:

Does nine levels matter versus, say, three? For most users, honestly, three would suffice. But for experienced vapers who dial in airflow as precisely as they dial wattage on a mod, the granularity is welcome. It's one of those features that costs nothing to include and occasionally makes a meaningful difference.

3D Curved LED Screen

The RX 50K's display wraps around the device body with a semi-curved surface. It shows battery percentage and e-liquid level via six segmented bars, a mode indicator, and airflow level icons. The "AI chip" (RAZ's marketing term) tracks usage patterns and updates the display with dynamic animations during draws.

Four light modes let you switch between Light and Dark display themes plus two animation styles. Dark mode is useful for nighttime use — less glare, lower battery consumption. Light mode offers better visibility outdoors. The screen isn't a gimmick, either: knowing exact battery and juice percentages eliminates the guesswork that plagues opaque disposables.

One note: the e-liquid indicator is digital rather than visual. Unlike the VUE 50K's transparent pod, you can't physically see the juice level. The digital readout was accurate to within about 5% during testing, which is good enough — but there's something reassuring about a clear tank that no algorithm replicates.

Dew Edition Flavors — All 5 Reviewed

The RX 50K runs an exclusive lineup of five "Code" flavors. These are soda-inspired profiles — fizzy, citrusy, and noticeably different from RAZ's standard fruit-and-ice catalog. All five were tested in Boost Mode (the recommended daily setting) with airflow at level 5.

The soda-fizz quality is the defining characteristic across all five. It's not just fruit + menthol — there's a carbonation-like sensation on the exhale that distinguishes the Dew Edition from standard disposable flavors. Code Blue and Code Red are the strongest sellers based on market data. Code White is the dark horse — the citrus layering rewards slower, longer draws in Normal Mode.

If the five-flavor limit feels restrictive, note that these same Dew Edition profiles are also available on the VUE 50K Replacement Pod system, alongside 5 additional classic RAZ flavors. However, on the RX 50K itself, the lineup is limited to these five.

RX 50K vs VUE 50K — Full Comparison

RAZ now offers two 50,000-puff devices with fundamentally different architectures. The numbers tell the story.

Choose the RX 50K if you want the most e-liquid per fill (19mL vs 13mL), prefer triple power modes including Super Boost, need 9-level airflow precision, or want the exclusive Dew Edition soda flavor lineup.

Choose the VUE 50K if you prioritize long-term cost savings through pod swaps ($12.99 vs $19.99 per cycle), want a transparent juice window, prefer classic RAZ flavors with more variety (10 vs 5), or like the flexibility of using the pod independently without the base.

RX 50K vs Full RAZ Lineup

The RX 50K sits at the top of the lineup on raw specs — most e-liquid, most power modes, most airflow control. The VUE 50K beats it on total battery capacity and ongoing economics. Each device below the 50K tier trades capacity for portability and simplicity, with the TN9000 remaining the most pocket-friendly option for users who don't need five-figure puff counts.

Battery and Charging

The 800mAh battery recharges via USB-C. In testing, a full charge from empty took roughly 50–60 minutes. With the 19mL tank, battery capacity is the limiting factor — you'll need to recharge multiple times before the juice runs out. In Normal Mode, expect 2–3 full charges per device. In Super Boost, charging frequency increases to roughly every 8,000–10,000 puffs.

The LED screen shows battery percentage down to single digits, which is useful for planning charges. The device warns when battery drops below 10%, and the screen dims automatically in standby to conserve power. USB-C fast charging means a 15-minute top-up adds enough charge for several hours of moderate use.

Who Should Buy the RX 50K

Heavy vapers who prioritize juice volume. At 19mL, the RX 50K holds more e-liquid than any other RAZ device. If running out of juice before running out of battery is your frustration with disposables, this addresses it directly.

Users who want maximum control. Three power modes plus nine airflow levels create 27 distinct draw configurations. No other RAZ disposable comes close to that level of customization.

Dew Edition flavor fans. If you've been chasing soda-inspired profiles and found them inconsistent in other brands, RAZ's execution here is solid. The fizzy carbonation quality is real, not just marketing copy.

Not ideal for: Cost-conscious vapers who go through devices weekly (the VUE 50K's pod-swap model is 35% cheaper per cycle after the first kit), users who want visual juice monitoring (VUE 50K's transparent pod wins), or anyone who needs the standard RAZ flavor roster (TN9000 and LTX 25K cover 40+ classic options).
