Nexa Ultra II Review: The Award-Winning 50K Disposable Tested

Our Nexa Ultra II review puts the 50K Vaping360 winner under the microscope.

It won Best Disposable Vape at the Vaping360 Awards 2025. So expectations run high.

Here, “tested” means we checked every claim against the published specs, the awards and the design.

We did not run a lab or count puffs by hand.

Instead, we explain what the hardware should deliver and where it falls short.

As an independent retailer, we sell several Nexa models.

That gives us no reason to push this one over the rest.

Quick Take on the Ultra II 50K

• Rating: 9 out of 10.
• Best for: heavy users who want 50,000 puffs in a compact body.
• Standout features: Juicy Lock, a 16 mL Crystal Tank, dark mode and a 900 mAh battery.
• Main drawback: it costs more per device than the other Nexa disposables.
• Our price: $18.99 for one, or $87.49 for a 5-pack.

If that is all you need, jump to the Ultra II collection. Otherwise, read on for the details.

What the Nexa Ultra II Changes

The original Ultra 50K debuted in October 2024. Then the Ultra II followed one year later, in October 2025.

Both models promise up to 50,000 puffs. However, the way they store and deliver e-liquid differs a lot.

The first Ultra uses a 5 mL prefilled pod plus a separate 15 mL container.

Its Clarilock structure pairs a Crystal Tank with a Flavor Booster.

By contrast, the Ultra II holds 4 mL in cotton and 16 mL in a larger Crystal Tank.

It also adds Juicy Lock, which keeps the e-liquid sealed until you activate the device.

Next, the battery grows from 800 mAh to 900 mAh. Finally, the 3D curved display now offers a dark mode.

Nexa calls the result its most compact 50K device.

In other words, you get the same puff rating in a slimmer package.

Our Ultra vs Ultra II comparison covers the upgrade in more depth.

Nexa Ultra II Specs and Rivals

Before we judge anything, here are the numbers.

We placed the Ultra II beside its closest rivals so the gaps stand out.

Spec	Ultra II 50K	Ultra 50K	Geek Bar Pulse X
Max puffs	50,000 Normal / 30,000 Turbo	50,000 Normal / 30,000 Turbo	25,000 Regular / 15,000 Pulse
E-liquid	20 mL (4 mL cotton + 16 mL Crystal Tank)	20 mL (5 mL pod + 15 mL container)	18 mL
Battery	900 mAh, USB-C	800 mAh, USB-C	820 mAh
Screen	3D curved, light and dark mode	3D curved display	3D curved screen
Sealed reservoir	Juicy Lock	Clarilock with Flavor Booster	Not listed in our specs
Nicotine	5% salt nicotine	5% salt nicotine	Not listed in our specs
Our price	$18.99	$13.49	Not sold here

On paper, the Ultra II doubles the Pulse X puff rating.

It also carries 2 mL more e-liquid and a larger battery.

Our Ultra II vs Geek Bar Pulse X breakdown explains where each one wins.

Ultra II Vape Design and Portability

Portability is the headline here.

Most 50K devices feel chunky, yet Nexa built this one to slip easily into a pocket.

The brand describes it as a slim, pocket-sized design.

We agree that it looks far less bulky than older high-capacity disposables.

The 3D curved display sits on the front.

It shows your battery and mode, then switches to dark mode on demand.

Meanwhile, the clear Crystal Tank shows how much e-liquid remains.

That window holds the bulk of the juice, so the reading means something.

There are no fire buttons. Instead, the device activates when you inhale.

Dark Mode in Daily Use

Dark mode switches on with a three-second press and hold. It gives the screen a darker, lower-key look.

This sounds minor, but it matters at night.

A bright screen in a dark room, a theater or a car draws attention.

So we count dark mode as a real quality-of-life feature.

The Pix, by comparison, lists no dark mode in our specs.

For the full button guide, see our screen and blinking guide.

Juicy Lock and the Crystal Tank

These two features define the Ultra II. Together, they aim to keep flavor fresh and waste low.

Juicy Lock keeps the e-liquid sealed away from the wick until you activate the device.

Nexa calls it “Fresher Taste, Press to Go.”

That matters because a disposable can sit in a warehouse or a store for weeks before you buy it.

Meanwhile, the Crystal Tank lets you watch your e-liquid level drop.

As a result, you can plan your next order.

The tank also aims to cut leftover residue. That way, more of the 20 mL actually reaches the coil.

We explain both systems in detail in our Juicy Lock and Crystal Tank explainer.

First-Time Setup

Activation takes about a minute. Follow these steps the first time you open a new device:

1. First, unbox the device and peel off any protective stickers.
2. Next, remove the silicone plugs from the mouthpiece and tank.
3. Then press the tank and body together until they click and start Juicy Lock.
4. After that, wait about a minute so the wick can soak up e-liquid.
5. Choose Normal mode for more puffs or Turbo for a stronger hit.
6. Finally, recharge with any USB-C cable when the battery runs low.

Skipping the one-minute wait is the most common setup mistake.

A dry wick can taste burnt on the first few puffs.

Our step-by-step Ultra II user guide adds photos and troubleshooting tips.

Ultra II Disposable Flavor Lineup

We stock 16 flavors for this device. The list leans toward ice and fruit, with two candy options.

Because Juicy Lock keeps the juice sealed, flavor should stay consistent from your first puff to your last.

Also, the large Crystal Tank holds most of the e-liquid.

So the wick keeps drawing from a full supply for longer.

Ice and Menthol Picks

Seven icy flavors make this a strong pick for menthol fans. Start with Miami Mint or Lemon Frozen.

Fruit-ice blends include Watermelon Ice, Blue Razz Ice and Strawberry Ice.

Then there is Sour Apple Ice and Georgia Peach Ice.

The Ultra II Ice Sampler bundles five icy flavors for $89.99.

For more cold picks across every device, read our icy flavors roundup.

Fruit and Candy Picks

Fruit fans get seven choices. Strawberry leads the way with Strawberry, Strawberry Mango and Strawberry Banana.

Also try Strawberry Colada, Black Cherry or Blueberry Watermelon.

Then BP rounds out the fruit family.

On the sweet side, pick White Gummy or Fcuking FAB.

Our best Nexa flavors list ranks favorites across the whole range.

Ultra II 50K Battery and Charging

The 900 mAh battery is the largest among the Nexa disposables we carry.

Nexa says it lasts all day on a single charge.

Of course, your habits decide that.

Long draws in Turbo mode will drain it faster than short sips in Normal mode.

When it runs low, any USB-C cable will top it up.

We also sell a USB-C cable for $4.99.

See our charging guide for habits that keep the battery healthy.

How Long 50,000 Puffs Could Last

Rated puff counts assume ideal conditions. Still, rough math helps you plan.

At 400 puffs a day, 50,000 puffs would last about four months.

At 800 a day, you would get roughly two months.

Turbo mode caps the device at about 30,000 puffs. So a Turbo-only user should expect around 40% fewer puffs.

For a deeper breakdown, read how long a Nexa Ultra II lasts.

Normal vs Turbo on the Ultra II Disposable

Dual modes let you trade puff count for a stronger hit. Normal is the efficient everyday setting.

Turbo, on the other hand, pushes more power for a bigger, warmer draw.

That costs about 20,000 puffs off the rating.

We suggest Normal as your default. Then switch to Turbo when you want a fuller hit for a short session.

Unlike the Pix, the Ultra II lists no adjustable airflow in our specs.

So mode is your main way to tune the draw.

Awards and Recognition

The Ultra II collected major praise within months of its October 2025 launch.

• Winner of Best Disposable Vape at the Vaping360 Awards 2025, with results announced in February 2026.
• Named among the best disposable vapes by Versed Vaper in 2025.

The Vaping360 win stands out because the Pix also placed third in the same category.

So the Ultra II beat its own sibling.

See every honor on our Nexa awards page.

Nexa Ultra II Pros and Cons

What We Like

• Up to 50,000 puffs in Nexa’s most compact 50K body.
• A 16 mL Crystal Tank makes your e-liquid level easy to read.
• Juicy Lock keeps juice sealed until you activate it.
• Dark mode switches on with a three-second press and hold.
• Its 900 mAh battery is the biggest among our Nexa disposables.
• It won Best Disposable Vape at the Vaping360 Awards 2025.

What Could Be Better

• At $18.99, it costs more than any other single Nexa disposable we sell.
• Turbo mode drops the rating to about 30,000 puffs.
• Our specs list no adjustable airflow, unlike the Pix.
• It offers 16 flavors, fewer than the 23 on the Pix or the original Ultra.
• When it runs dry, you replace the whole device.

Who Should Buy the Ultra II Vape?

This device makes the most sense for specific vapers. Here is who we think gets the best value from it.

• Heavy users who empty smaller disposables too quickly.
• Night owls and commuters who want dark mode.
• Menthol fans, thanks to seven icy flavors.
• Anyone who wants to see exactly how much e-liquid remains.

On the other hand, light vapers may never use all 20 mL before they crave a new flavor.

The Pix suits them better.

If you want refillable convenience, look at the Flex range instead. Our Flex vs Ultra II guide compares them.

Better Picks for Discreet Use

Some buyers care more about low visibility than raw capacity. For them, the InvisaCloud makes a strong case.

A light inhale gives normal vapor, while a slow, deep inhale leaves almost no cloud.

It also keeps a 20 mL capacity and dual modes, yet costs $13.49 on our store.

See the InvisaCloud range or read our InvisaCloud explainer for details.

Value for Money

The sticker price looks high at first. However, the math changes once you factor in capacity.

At $18.99 for up to 50,000 puffs, you pay about four cents per 100 puffs.

That matches the Pix almost exactly.

The 5-pack drops the price to about $17.50 per device. Check our price guide for every deal.

Ultra II or Pix: Which Nexa Fits You?

Many shoppers narrow their choice to these two award winners. So here is how we split them.

Choose the Ultra II if capacity matters most.

It holds 20 mL against 16 mL and rates 50,000 puffs against 35,000.

Choose the Pix if size and draw control matter more.

It is palm-sized, cheaper at $14.49 and offers adjustable airflow.

Both share Juicy Lock and a Crystal Tank. As a result, freshness and visibility stay the same either way.

Dark mode tips the scale for some buyers. Only the Ultra II lists it in our specs.

Still undecided? Our Ultra II vs Pix page and our Pix breakdown go deeper.

Daily Care and Storage Tips

A 50K device can stay with you for months. A few simple habits help it perform well the whole time.

1. Store spare devices upright and away from heat, both before and after activation.
2. Keep the device out of hot cars and direct sun.
3. Charge when the display shows a low battery, rather than waiting for it to die.
4. Glance at the Crystal Tank each week so you can reorder in time.
5. Use Normal mode as your default to stretch both e-liquid and battery.
6. Add a silicone sleeve for grip or a lanyard for easy carry.

Browse every add-on in our accessories section.

Common Problems and Quick Fixes

Most issues come from setup or charging, not from a faulty device. Try these fixes before you contact us.

• No vapor at all? Check that the tank and body clicked together, since that starts Juicy Lock.
• Dry or burnt taste? Wait about a minute after activation, then take a few gentle puffs.
• Weak hits? Charge the battery, because low power can soften each draw.
• Screen looks off? You may have switched to dark mode with a three-second press.
• Flavor fading early? Check the Crystal Tank, since the juice may simply be running low.

When none of that works, our not-hitting guide covers deeper troubleshooting.

Spotting a Genuine Device

Award winners attract counterfeits. A fake will not match the specs, the seal or the flavor we describe here.

So verify the code on every box with the official verification page.

Our authenticity page and our fake-spotting guide list the warning signs.

Nexa Ultra II Review Verdict: 9 Out of 10

We rate the Ultra II 9 out of 10. Here is why it lands there.

First, it delivers the full 50,000-puff rating in a body built for a pocket.

That is the hardest trick in this category.

Second, Juicy Lock and the 16 mL Crystal Tank work together. One protects freshness, while the other shows what remains.

Third, dark mode and the 900 mAh battery add real everyday value.

So why not a perfect 10? The price runs higher than other Nexa disposables, and airflow stays fixed.

Overall, this Nexa Ultra II review finds a device that earns its Vaping360 crown.

Frequently Asked Questions

How many puffs does the Ultra II give?

Each device gives up to 50,000 puffs in Normal mode.

However, Turbo mode trades that for a stronger hit and about 30,000 puffs.

How do I turn on dark mode?

Press and hold for three seconds. The display then switches to dark mode.

Does the Ultra II leak?

Juicy Lock keeps the e-liquid sealed until you activate the device.

Also, storing it upright and away from heat helps prevent leaks.

How do I charge it?

It charges through a USB-C port on the 900 mAh battery. So any standard USB-C cable works.

Why does my first puff taste dry?

You probably vaped right after activation. Next time, wait about a minute so the wick can soak up e-liquid.

What nicotine strength does it use?

Every device uses 5% (50 mg/mL) salt nicotine. Our nicotine strength guide explains what that means for you.
