NEXA Ultra II vs Orion Bar 50K: Which 50K Puff Disposable Wins?

In the ever-evolving world of high-puff disposables, two names stand out: the Orion Bar 50K and the NEXA Ultra / Ultra II series. Both promise long lifespans, advanced visuals, and feature sets that push beyond the typical “inhale and go” disposables. But which one delivers more practical value, better flavor, and reliability? In this review, I’ll compare them head-to-head and try to humanize the experience, not just list specs.

Design & Aesthetics

Orion Bar 50K

From the moment you hold it, the Orion Bar 50K aims to impress. The smooth, rounded body makes it comfortable to grip. Many reviewers have noted its 360° infinite “galaxy” screen, which wraps around the device, producing visual effects with each puff. Versed Vaper+2Vaping.com+2 This display is eye-catching, and gives the Orion Bar a futuristic feel.

Because the screen is around the body, no matter which side you glance at, you’ll see animations or lighting effects — that is, until you disable or dim it (if the device allows). The finish tends to be glossy and modern, giving off a premium vibe.

One potential downside is that flashy screens can draw attention (and battery). Also, with a wraparound display, you may worry about durability or scratches over time. But in terms of wow factor, Orion nails it.

NEXA Ultra / Ultra II

NEXA’s design philosophy is centered around a 3D curved screen and crystal tank / transparent e-liquid window. Vaping360+3Nexa Bar+3Versed Vaper+3 The curved screen adds a dimensional flair, with glowing visuals that react during use. The display also shows battery status and mode.

One of NEXA’s advertised innovations is the “ClariLock structure” (or “Crystal Tank technology”) intended to let you see precisely how much e-liquid remains and minimize residual fluid wasted in cotton or wick. Nexa Bar Their marketing also claims this results in up to ~35% more usable e-liquid compared to traditional designs. Nexa Bar

Also, the NEXA Ultra / Ultra II lineage often employs a two-part chassis (battery + detachable tank) so that e-liquid isn’t attached until just before use, helping reduce leakage during shipping. Nexa Bar+3Versed Vaper+3Element Vape+3 In short: elegant, functional, and built to showcase what’s inside.

In comparison to Orion, NEXA’s design is more restrained (less flashy wrap), but arguably more functional — you can literally see your e-liquid level and mode info at a glance.

Features & Specs (Practical Use)

Below is a side-by-side style breakdown, followed by commentary.

Feature	Orion Bar 50K	NEXA Ultra / Ultra II (Ultra 2 / Ultra 50K lineage)
Battery	920 mAh (rechargeable via USB-C) — as per your spec	~900 mAh built-in rechargeable (Ultra II)
E-liquid / Puff count	28 mL, ~50,000 puffs, 5% nicotine strength, draw-activated, adjustable airflow, “ice & nic control system” (i.e. user control over nicotine boost / cooling effect)	Ultra II: 4 mL in storage cotton + 16 mL crystal tank = 20 mL effective; ~50,000 puffs (Norm mode) or ~30,000 in Turbo mode; 5% nicotine strength; dual 1.0 Ω mesh coils; light/dark screen modes; click-to-install tank; MTL vape style
Modes / Control	Has “ice & nic control” system: likely a toggle or slider to adjust how much “cooling / ice effect” and potentially nicotine delivery. (Some reviews mention flavor / ice boosting) Element Vape+3Mi-One Brands+3Vaping.com+3 Also adjustable airflow.	NEXA Ultra II allows switching between modes (Norm / Turbo) for flavor intensity or longevity, plus ability to choose light/dark screen mode. Dual mesh coils help maintain consistent heating.
Display & Indicators	360° “galaxy” screen with animated visuals. Because it’s wraparound, it is more immersive. Some concerns that more screen ≠ more info (you may not always see battery or mode info depending on UI).	3D curved screen, battery indicator, shows mode, and can toggle between light/dark display. More minimal but functional display.
Tank / Liquid monitoring	Since Orion’s spec says 28 mL and has a wrap display but I found no claim of fully transparent tank — likely relies more on screen indicators than direct visibility	Transparent crystal tank / ClariLock structure lets you see level and ensure you use nearly all e-liquid (less waste in wicking).
Airflow & draw style	Adjustable airflow slider so you can tighten or loosen draw. The “ice & nic control” may affect throat hit or cooling.	Also adjustable airflow, designed mainly for MTL vaping but with enough adjustability and the two modes you can tailor draw feel.
Performance / flavor & vapor production	Users praise “layers of tropical sweetness,” solid vapor, and smooth draws. Element Vape+2Versed Vaper+2 However, some report that the 50K puff claim is optimistic: e-liquid seems to drop before such counts. Reddit+1	NEXA Ultra’s dual mesh coils, mode switching, and full vaporization design yield smooth and clean flavor with minimal dry hits. Nexa Bar+3Vaping360+3Versed Vaper+3 In reviews, the Ultra is praised for hitting very well, no gurgles or leaking, and flavor consistency. Vaping360+1
Efficiency & waste	Because Orion is likely to use more traditional wicking + wrap display, some e-liquid might remain unused in cotton or corners, though the 28 mL figure is generous.	NEXA’s design attempts to minimize waste via its ClariLock / crystal tank design. Also, because the tank is detached until use, there is less seepage or waste before you start.
Charging / usability	USB-C recharge; draw-activated, no buttons (as typical)	USB-C recharge; draw-activated; button for mode adjustment and screen mode switching; click-to-install tank
Durability / leak prevention	Some users worry about wrap-screen durability (scratches), and leaks are always a risk in disposables. I found no large reports of leaks for Orion.	The detachable tank system helps mitigate leakage during transport. NEXA claims their lock / seal designs reduce leakage. Nexa Bar

Human Experience & Edge Cases

Visual appeal vs practicality: Orion impresses visually. That wraparound galaxy screen is fun and flashy. But in poor lighting or glare conditions, you may find the display less legible. NEXA’s approach is more utilitarian — clean, readable display, and transparency of the tank.
Flavor over time: With Orion, heavy use or boosting ice may accelerate depletion or reduce flavor toward the end. Some users report the impressive “50K puffs” as theoretical rather than practical. Reddit+1 Meanwhile, NEXA’s design to eliminate residual waste may help maintain flavor consistency deeper into the device life.
Ease of replacement or modularity: With NEXA’s click-to-install tank, in theory (though device is disposable) one might imagine future modularity or refilling, though that’s not marketed — the device is ultimately disposable. Orion’s design is more monolithic.
Battery drain by screen effects: Orion’s full wrap effects may draw extra current, potentially reducing the effective usable puffs or battery headroom, especially if the display is always active. NEXA’s more restrained display might tradeless battery overhead.

Conclusion: Which One to Choose?

If I were to sum up:

Go with Orion Bar 50K if you prioritize striking visuals, immersive display effects, and enjoy the “wow factor.” It’s a head-turner and makes vaping feel futuristic.
Go with NEXA Ultra II / Ultra lineage if you prefer functional transparency, reliability, minimal waste, consistent flavor through the life of device, and a balanced combination of aesthetics and practicality.

In my view, the NEXA Ultra II (or Ultra) offers better real-world consistency: less waste, clean flavor, and a display that supports usability rather than showmanship. Orion is an exciting device and might be your pick if you want something that stands out — though you may sacrifice some efficiency.
