Choosing between the Hayati Pro Ultra+ 25K and Pro Max+ 6K is not simply a matter of selecting the device with the larger advertised puff count.

Both are rechargeable Hayati prefilled pod systems with an 850mAh battery, 20mg nicotine salt e-liquid and replaceable e-liquid components. However, they are designed for different priorities.

The Hayati Pro Max+ 6K focuses on straightforward single-flavour use, a narrow pocket-friendly body and a smaller 12ml total e-liquid system. The Hayati Pro Ultra+ 25K provides a larger 22ml system, two independently operating flavour sections and a twistable mouthpiece that lets users move between flavours.

At Hayati Pro, we specialise exclusively in Hayati products. This comparison explains their differences in capacity, portability, battery performance, flavour selection and daily convenience so you can decide which system better suits your requirements.

What Do the Two Hayati Kits Have in Common?

Although the devices serve different usage styles, they share several important features.

Both use:

• An 850mAh built-in rechargeable battery
• 20mg nicotine salt e-liquid
• Replaceable e-liquid components
• Automatic transfer from a larger container into a compliant pod section
• A visible e-liquid area
• A battery-status display
• Type-C recharging
• Straightforward operation without adjustable wattage menus

Hayati describes both devices as rechargeable, replaceable and refillable systems. The brand states that the Pro Max+ uses a detachable 2ml cartridge with a 10ml container, while the Ultra+ combines a 2ml cartridge with two 10ml containers.

This means the fundamental experience remains familiar whichever one you select. You are not moving from a basic vape to a complicated high-powered mod. You are choosing between a simpler single-flavour format and a larger dual-flavour format.

Hayati Pro Max+ 6K Overview

The Hayati Pro Max+ 6000 is the more compact and straightforward option.

It uses a 2ml pod connected to a 10ml refill container, creating a total stated e-liquid capacity of 12ml. As e-liquid is used from the pod section, the larger container supports continued refilling without requiring the user to pour bottled liquid into the device.

The kit has an 850mAh battery, 1A charging support, a transparent e-liquid area and a smart battery display. Hayati currently lists 65 flavour options for the standard Pro Max+ range.

Its tall and narrow construction makes it more similar to a conventional pen-style vape. At 28mm wide, it should fit more naturally into smaller pockets than the wider Ultra+.

Who Is the Pro Max+ 6K Designed For?

The Pro Max+ is likely to suit adult users who:

• Prefer one flavour throughout each pod cycle
• Value a slim device
• Want fewer components to assemble
• Prefer a familiar prefilled-pod format
• Do not need dual-flavour switching
• Want access to the widest current Hayati flavour range

Its main advantage is not that it lacks features. Its advantage is that it keeps the experience focused.

Insert the compatible components, allow the e-liquid system to connect correctly and inhale. There is no need to select between two tanks or rotate the mouthpiece before every flavour change.

Hayati Pro Ultra+ 25K Overview

The Hayati Pro Ultra+ 25000 expands the same basic concept into a larger dual-system device.

It combines a 2ml cartridge section with two separate 10ml containers, giving it a total official stated capacity of 22ml. The device also uses two independent coil sections, allowing compatible flavour combinations to remain separate.

A twistable mouthpiece controls which flavour side is active. Rather than carrying two complete devices, the user can rotate the mouthpiece and move between the available profiles within the same kit.

Hayati also gives the Ultra+ a wider metal body, smart battery information and screen animation. Its official dimensions are 53.3 × 107 × 29.3mm, making it shorter but almost twice as wide as the Pro Max+.

Who Is the Pro Ultra+ 25K Designed For?

The Ultra+ is likely to suit adult users who:

• Use their vape frequently
• Want a larger e-liquid system
• Prefer fewer replacement-pack changes
• Experience flavour fatigue
• Want two flavour profiles in one device
• Do not mind carrying a wider kit
• Value additional screen interaction

Its primary benefit is convenience over a longer usage cycle rather than absolute simplicity.

Puff Count and Expected Longevity

The largest numerical difference is the advertised puff count.

The Pro Max+ is rated at 6,000+ puffs, while the Pro Ultra+ is rated at 25,000+ puffs.

That does not guarantee that the Ultra+ will provide exactly 4.17 times as many puffs for every user. Puff count is affected by:

• Draw duration
• Strength of each inhale
• Frequency of use
• Time between draws
• Battery condition
• Coil behaviour
• E-liquid transfer
• Individual vaping technique

A user taking short, controlled mouth-to-lung inhales may obtain more puffs than someone taking prolonged draws.

The reliable comparison is that the Ultra+ has a substantially larger e-liquid system and is designed for a much longer replacement cycle. The exact number of days cannot be guaranteed.

Which Lasts Longer?

The Pro Ultra+ 25K is the clear choice when longevity between replacement packs is the main consideration.

The Pro Max+ 6K remains suitable when you prefer to change flavours more regularly or do not need such a large quantity within one setup.

E-Liquid Capacity: 12ml vs 22ml

The Pro Max+ uses:

• One 2ml pod
• One 10ml container
• 12ml stated total capacity

The Pro Ultra+ uses:

• One 2ml cartridge system
• Two 10ml containers
• 22ml stated total capacity

Hayati’s official specification for the Ultra+ is written as 2 + 2 × 10ml. This equals 22ml. It should not be described as 24ml unless a different verified version specifically includes two separate 2ml cartridges.

The Ultra+ therefore provides 10ml more stated e-liquid capacity than the Pro Max+.

This difference matters most to frequent users. Someone who vapes less regularly may prefer the smaller Pro Max+ system because it allows them to move to a new flavour sooner.

Single-Flavour vs Dual-Flavour System

Pro Max+ 6K: One Flavour at a Time

The Pro Max+ provides one selected flavour through its pod and container combination.

This format offers:

• Consistent flavour throughout the setup
• Fewer moving parts
• No flavour-selection control
• Simple replacement
• Easier flavour identification

It works particularly well for users who already know their preferred Hayati flavour.

Pro Ultra+ 25K: Two Flavours in One Device

The Ultra+ uses two independent tanks and coils with a twistable mouthpiece.

Hayati describes the system as “double flavour” with a “double independent coil” design. Rotating the mouthpiece lets the user select the relevant side without mixing the two e-liquids.

This provides several practical benefits:

• Switch flavours without replacing the device
• Reduce flavour fatigue
• Carry one kit instead of two
• Keep both profiles separate
• Alternate between complementary flavours

The dual-flavour feature is the most important functional difference after puff capacity.

Which Has the Better Flavour Range?

The answer depends on what “better” means.

The standard Pro Max+ range currently has 65 listed flavours, while the Pro Ultra+ range has 45 listed options. These figures come from Hayati’s catalogue updated on 20 and 24 June 2026.

Pro Max+ Offers More Individual Options

The Pro Max+ includes a broad selection of:

• Berry flavours
• Tropical fruits
• Lemonade blends
• Mint profiles
• Ice flavours
• Bubblegum combinations
• Cola-inspired options
• Multi-fruit blends

Examples include Blue Razz Lemonade, Cherry Cola, Fresh Mint, Juicy Peach, Lemon & Lime, Mr Blue, Strawberry Raspberry Ice and Triple Mango.

Pro Ultra+ Offers More Variety Per Device

The Ultra+ has fewer current listings overall, but many are dual-flavour combinations.

Examples include:

• Blackcurrant Cotton K / Blue Raspberry
• Grape GB / Strawberry GB
• Kiwi Banana / Strawberry Banana
• Fresh Mint / Blue Razz & Mint
• Lemon & Lime / Lemon & Blueberry
• Sour Apple / Juicy Peach
• Blue Razz Pineapple / Strawberry Ice

The Ultra+ therefore offers fewer listed products but more flavour flexibility inside an individual device.

Flavour Range Verdict

Choose the Pro Max+ when you want the widest overall choice of single flavours.

Choose the Pro Ultra+ when you want two profiles available without changing the device.

Battery and Charging Comparison

Both devices use the same 850mAh battery capacity.

This means the Ultra+ does not contain a proportionally larger battery despite holding substantially more e-liquid. The battery is designed to be recharged repeatedly throughout the longer life of the pod system.

Hayati states that these systems use Type-C charging and are designed for repeated charge cycles. The Pro Max+ official page also specifies 1A fast charging.

Does the Ultra+ Last Longer Between Charges?

Not necessarily.

Its higher puff rating describes the total potential use from the complete e-liquid system, not the amount delivered from one battery charge.

Both have the same 850mAh cell, so charging frequency will depend primarily on:

• Number of daily puffs
• Draw length
• Coil operation
• Screen activity
• Battery condition

A frequent user may recharge either device regularly. The Ultra+ advantage is that its e-liquid components remain usable across more charging cycles.

Size and Portability

The Pro Max+ measures 28 × 124.7 × 28mm.

The Pro Ultra+ measures 53.3 × 107 × 29.3mm.

Pro Max+ Shape

The Pro Max+ is:

• Taller
• Considerably narrower
• Easier to place in a slim pocket
• More similar to a pen-shaped device
• Better suited to users prioritising portability

Pro Ultra+ Shape

The Pro Ultra+ is:

• Shorter
• Much wider
• Designed around two tanks
• More substantial in the hand
• Better suited to users prioritising capacity

The Pro Ultra+ is not simply a larger version in every direction. It is shorter than the Pro Max+ but uses a significantly wider dual-tank body.

Display and User Interface

Both devices provide battery information, helping users monitor power without waiting for the device to stop operating.

The Pro Max+ has a smart battery display and transparent e-liquid area.

The Pro Ultra+ adds:

• Smart battery information
• A transparent tank area
• Screen animation
• Dual-flavour interaction
• Twist-controlled flavour selection

Hayati presents the Ultra+ as the more interactive system, while the Pro Max+ uses a simpler information display.

Choose the Pro Max+ when you want essential information without extra interaction. Choose the Ultra+ when you value a more visible and feature-led interface.

Ease of Setup

Setting Up the Pro Max+ 6K

The Pro Max+ generally involves:

1. Removing all protective seals.
2. Connecting the 2ml pod and 10ml refill container as directed.
3. Installing the assembled pod system into the device.
4. Allowing the e-liquid to transfer correctly.
5. Inhaling through the mouthpiece.

Its single-flavour design keeps the setup relatively straightforward.

Setting Up the Pro Ultra+ 25K

The Ultra+ involves additional components because it contains two refill containers and two independently operating flavour sections.

General setup involves:

1. Removing the packaging and protective seals.
2. Connecting both refill containers to their designated sections.
3. Installing the complete pod assembly.
4. Allowing the liquid-transfer system to settle.
5. Rotating the mouthpiece to select a flavour.
6. Inhaling through the active side.

Always follow the instructions provided with the specific retail version. Incorrectly connecting a container may prevent proper e-liquid transfer or cause leakage.

Nicotine Strength and Throat Hit

Both systems are officially listed at 20mg nicotine strength.

UK consumer vape rules restrict nicotine-containing e-liquid to a maximum concentration of 20mg/ml.

The 20mg strength is more likely to suit existing adult users who already consume higher-strength nicotine salt products. It may feel too strong for:

• Light nicotine users
• People accustomed to 3mg, 5mg or 10mg liquids
• Users who vape very frequently
• Anyone without an existing nicotine requirement

Do not select the Ultra+ solely because it offers more puffs. Both devices use the same listed nicotine strength, so the choice should be based on format and capacity rather than an assumption that one delivers weaker nicotine.

Cost and Long-Term Value

Retail prices change by seller, promotion and flavour, so fixed prices should not be permanently included in an evergreen comparison.

The practical value difference is:

Pro Max+ Value

The Pro Max+ generally provides:

• A lower initial product commitment
• A smaller e-liquid quantity
• Easier flavour changes between packs
• A compact complete setup
• More single-flavour choices

Pro Ultra+ Value

The Pro Ultra+ generally provides:

• More e-liquid within one replacement cycle
• A higher advertised puff capacity
• Two flavours in one device
• Fewer replacement-pack changes
• Greater long-term convenience for frequent users

The Ultra+ may offer stronger value per millilitre or estimated puff, but only when the user genuinely needs the additional capacity.

Buying a 25K system provides little practical benefit if the user prefers changing flavours frequently or does not vape often.

Which Is Better for New Users?

The Pro Max+ 6K has the simpler format.

It has one flavour, fewer components and no mouthpiece rotation to manage. This makes the system easier to understand for someone moving from a straightforward prefilled or single-use device.

However, both kits contain 20mg nicotine salt e-liquid. A new vape user with a lower nicotine requirement should not automatically choose either system simply because the Pro Max+ is easier to operate.

The Pro Ultra+ 25K may still suit a new user who already understands their nicotine needs and specifically wants two flavours, but it involves a larger initial quantity and more components.

Which Is Better for Frequent Vapers?

The Pro Ultra+ 25K is better aligned with frequent use because it provides:

• A larger 22ml total system
• A higher manufacturer-rated puff count
• Two flavour sections
• Reduced replacement frequency
• Flavour switching during the same usage cycle

The Pro Max+ remains capable of regular daily use, but its smaller system will reach replacement time sooner.

Which Is Better for Flavour Switching?

The Pro Ultra+ 25K wins this category.

Its twistable mouthpiece and independent flavour sections are specifically designed for switching between two options.

The Pro Max+ is better for users who want to select one flavour and keep the experience consistent.

Which Is More Portable?

The Pro Max+ 6K is the more portable choice due to its 28mm-wide body.

Although it is taller, it occupies less horizontal space and should feel more natural in a narrow pocket.

The Ultra+ remains compact relative to its capacity, but the 53.3mm width is noticeable. Its dual-tank construction prioritises capacity over minimal bulk.

Which Produces Better Flavour?

Neither device can be declared universally better without controlled testing.

Flavour perception depends on:

• Selected flavour
• Coil condition
• Draw length
• Airflow design
• E-liquid temperature
• Battery charge
• Individual taste

The Pro Max+ provides a consistent single-flavour experience.

The Pro Ultra+ provides two separate flavour paths and independent coils, reducing the likelihood of the two profiles mixing. Its advantage is variety rather than a guaranteed increase in flavour intensity.

Final Verdict

The Hayati Pro Max+ 6K and Hayati Pro Ultra+ 25K deliver two different interpretations of a rechargeable prefilled Hayati pod kit.

The Pro Max+ is the more focused option. Its slim body, single-flavour system and 12ml capacity make it easy to carry and straightforward to use. It also currently offers the broader total flavour range, with 65 official options.

The Pro Ultra+ is the more feature-rich option. Its 22ml system, dual independent coils and twistable mouthpiece allow users to carry two flavours and switch between them without changing devices. Its higher estimated puff count also means fewer replacement cycles for frequent users.

Choose the Pro Max+ 6K for portability, simplicity and single-flavour consistency.

Choose the Pro Ultra+ 25K for capacity, flavour switching and longer-term convenience.

The larger figure does not automatically make the Ultra+ the correct choice. The best Hayati vape is the one that matches how frequently you vape, how often you change flavours and how much device width you are comfortable carrying.

Nicotine is addictive. These products are intended only for adults who already use nicotine and are not risk-free.

Hayati Pro Ultra+ 25K vs Pro Max+ 6K FAQs

What is the main difference between the Hayati Pro Ultra+ and Pro Max+?
