The Ultra II leads in raw capacity — more puffs, more liquid, bigger battery. The PIX counters with a smaller footprint and a lower price tag. Both run identical coils and the same Juicy Lock seal, so vapor quality stays consistent across the lineup. For more details, check our guide on how long each NEXA model lasts.
Battery Life and Charging: 900 mAh vs 800 mAh
The Ultra II packs a 900 mAh cell. The PIX carries 800 mAh. In practice, both last roughly 1–2 days between charges depending on draw frequency and mode.
| Metric | Ultra II 50K | PIX 35K |
|---|---|---|
| Battery Capacity | 900 mAh | 800 mAh |
| USB-C Charge Time | 45–60 min | ~70 min |
| Pass-Through (vape while charging) | Yes | Yes |
| Charges per Full Lifespan (est.) | 15–25 cycles | 12–20 cycles |
The Ultra II charges faster and holds more energy per cycle. That said, the PIX still comfortably covers a full day of moderate use (200–300 draws). Both support pass-through charging — plug in a USB-C cable and keep vaping.
Normal Mode vs Turbo Mode: Puff Count Breakdown
Both the Ultra II and PIX ship with two power modes. Normal mode conserves liquid and battery for maximum puffs. Turbo (or Boost) mode cranks up wattage for denser clouds and stronger throat hit — at the cost of burning through juice faster.
| Mode | Ultra II 50K | PIX 35K |
|---|---|---|
| Normal Mode Puffs | 50,000 | 35,000 |
| Turbo/Boost Mode Puffs | 30,000 | 20,000 |
| Puff Reduction in Turbo | -40% | -43% |
Rated puff counts assume short 1-second draws under lab conditions. Real-world usage with 2–3 second pulls typically yields 40–60% of rated numbers. Here is what that looks like day-to-day:
Bottom line: the Ultra II gives you roughly 40% more days between replacements at the same usage rate. If you run through devices quickly, the Ultra II stretches your dollar further. If you vape lightly and swap flavors often, the PIX runs out before you get bored of it — which some vapers prefer.
Flavor Delivery: Bold vs Smooth
Both devices use the same 1.0 Ω dual mesh coil, but the tank architecture changes the flavor profile. The Ultra II's single crystal tank delivers juice in a straight path to the coil, producing richer, bolder hits — especially noticeable in Boost mode, where sweetness and ice kick up a notch.
The PIX splits its 16 mL across a dual reservoir (11 mL visible + 5 mL cotton-fed). This design meters juice more gradually, resulting in a smoother, mellower draw with less variation from first puff to last. Tart and citrus flavors stay crisp on the PIX without the sweetness surge you get on the Ultra II in Turbo.
| Flavor Trait | Ultra II 50K | PIX 35K |
|---|---|---|
| Overall Profile | Bold, rich, pronounced | Smooth, mellow, consistent |
| Ice/Menthol Flavors | Stronger cooling sensation | Softer menthol finish |
| Fruit/Citrus Flavors | Sweeter, amplified | Tart, crisp, true-to-fruit |
| Consistency (first to last puff) | Good — slight muting near end | Very consistent across lifespan |
If you like Cool Mint, Miami Mint, or Cherry Bomb with maximum punch, the Ultra II is your pick. If you prefer Strawberry Mango or Blue Razz Ice to taste clean and balanced all the way through, lean toward the PIX. See the full 33 NEXA flavors ranked and reviewed for detailed flavor notes.
Size, Weight, and Portability
This is where the two devices diverge most visually.
| Dimension | Ultra II 50K | PIX 35K |
|---|---|---|
| Height | 125 mm | 92 mm |
| Width | 27 mm | 58 mm |
| Depth | 27 mm | 22 mm |
| Weight | ~89 g | ~80 g |
| Form Factor | Tall cylinder (pen-style) | Wide pebble (AirPods-case shape) |
The Ultra II is a tall, slim cylinder that sits upright in a shirt pocket. The PIX is a squat pebble — wider but shorter. Reviewers compare the PIX to an AirPods Pro charging case. It slides into a jeans pocket without printing through fabric.
For on-the-go use, the PIX is the more discreet option. For desk or home use where size does not matter, the Ultra II's pen-style grip may feel more natural. Check the setup instructions for both devices if you want first-use details.
Price and Value: Cost Per Puff
At first glance, the $1 price gap between the Ultra II ($23.99) and PIX ($22.99) looks negligible. But the cost-per-puff math flips the script.
| Metric | Ultra II 50K | PIX 35K |
|---|---|---|
| Retail Price | $23.99 | $22.99 |
| Rated Puffs (Normal) | 50,000 | 35,000 |
| Cost per 1,000 Puffs | $0.48 | $0.66 |
| Real-World Puffs (est. 50%) | ~25,000 | ~17,500 |
| Real-World Cost per 1,000 | $0.96 | $1.31 |
The Ultra II delivers 27% more value per puff than the PIX at current pricing. For heavy vapers replacing devices every week, that adds up to roughly $15–20 saved per month. For light users who replace a device every 2–3 weeks, the difference is about $3–5 per month — still meaningful over a year. Visit the NEXA pricing page for current deals and bulk options.
All electronic nicotine delivery systems sold in the U.S. fall under FDA tobacco product regulations. Both NEXA devices carry standard compliance markings.
Which NEXA Should You Buy?
There is no universal winner. The right pick depends on how you vape. Here are three common profiles:
Pick the Ultra II 50K if you:
- Vape heavily (300+ draws/day) and want maximum longevity
- Prefer bold, amplified flavors — especially ice and menthol
- Use Turbo/Boost mode frequently for denser clouds
- Value cost per puff over upfront price
- Keep the device at a desk, nightstand, or bag (size is not a concern)
Pick the PIX 35K if you:
- Want a pocket-friendly device you can carry anywhere
- Prefer smooth, consistent flavor from first puff to last
- Vape lightly or moderately (under 300 draws/day)
- Like swapping flavors often — a smaller capacity means faster rotation
- Want the lowest upfront spend ($22.99 vs $23.99)
Still unsure?
Start with the PIX 35K. It costs less, runs out sooner so you can try more flavors, and its compact form factor works for any lifestyle.

FAQ
Q1. What is the difference between NEXA Ultra II 50K and PIX 35K?
The Ultra II is a larger device with 50,000 rated puffs, a 20 mL crystal tank, and 900 mAh battery. The PIX is a compact pebble-shaped device with 35,000 puffs, a 16 mL dual reservoir, and 800 mAh battery. Both share the same dual mesh coil and Juicy Lock leak protection.
Q2. Which NEXA vape lasts longer, Ultra II or PIX?
The Ultra II lasts roughly 40% longer thanks to its larger e-liquid capacity (20 mL vs 16 mL). At moderate use (~300 draws/day), expect about 8 days from the Ultra II and 6 days from the PIX under real-world conditions.
Q3. Do 50,000 puff vapes actually last 50,000 puffs?
Rated puff counts assume 1-second lab draws. Real-world draws run 2–3 seconds, so actual puffs typically land at 40–60% of the rated number. For the Ultra II, expect roughly 20,000–30,000 real-world puffs.
Q4. Is the NEXA PIX 35K good for beginners?
Yes. Its compact size, draw-activated firing (no buttons), and smooth flavor delivery make it one of the most approachable disposable vapes on the market. It is also $1 cheaper than the Ultra II.

Flavor is subjective. The Ultra II produces bolder, more amplified flavor with extra sweetness in Boost mode. The PIX delivers smoother, more consistent flavor across its full lifespan. Fruit-forward vapers tend to prefer the PIX; menthol fans lean toward the Ultra II.
Q6. Is the NEXA Ultra II worth the extra cost over the PIX?
For frequent vapers, yes. The Ultra II costs $0.48 per 1,000 rated puffs compared to $0.66 for the PIX — a 27% savings. The extra $1 upfront buys 15,000 additional puffs.
Q7. Can you vape the NEXA Ultra II while it charges?
Yes, both the Ultra II and PIX support pass-through charging via USB-C. You can draw on the device while it is plugged in.
Q8. Does the NEXA PIX 35K have a screen?
