Hayati Rubik Review - Is It Trusted
The Hayati Rubik 7000 is a rechargeable prefilled pod kit designed for adult vapers who want more use from one device without moving to a manually refillable vape.
Its compact cube-shaped body immediately separates it from the long, pen-style devices commonly found in the high-puff pod category. Inside, it combines an 850mAh rechargeable battery with a 2ml prefilled pod and a 10ml auto-refill container. Together, these provide 12ml of 20mg nicotine salt e-liquid and an advertised capacity of up to 7,000 puffs.
There are no buttons, adjustable settings or separate coils to install. You connect the pod and refill container, insert the assembled refill into the device and inhale through the mouthpiece. That simplicity makes the Hayati Rubik 7000 appealing, but is it genuinely better than other rechargeable prefilled kits, or is the unusual shape its main selling point?
This Hayati Rubik review examines its design, flavour delivery, battery performance, refill system, ease of use and overall value to help you decide whether it is the right vape for you. This product contains nicotine and is intended for adults aged 18 and over. It is not suitable for non-smokers.
Hayati Rubik 7000 Review Summary
The Hayati Rubik 7000 is a straightforward and practical prefilled pod kit. Its 2ml pod and 10ml auto-refill container provide considerably more e-liquid than a basic low-capacity pod, while the rechargeable device can be reused with compatible Hayati Rubik refill packs.
Its strongest features are its compact cube-shaped design, clear LED display, uncomplicated inhale activation and consistent mouth-to-lung draw. The refill system removes the mess and maintenance normally associated with bottled e-liquid.
The main limitation is flexibility. The device is designed specifically for 20mg Hayati Rubik refill packs, and it does not provide adjustable airflow, variable power or support for bottled e-liquid. It is therefore better suited to convenience-focused users than experienced vapers who want greater control.
The Hayati Rubik 7000 is a good everyday choice for adult smokers and existing disposable-style vape users who want a rechargeable, low-maintenance alternative with a distinctive compact design.

What is the Hayati Rubik 7000?
The Hayati Rubik 7000 is a reusable device that works with replaceable prefilled refill packs.
Each refill pack contains two connected parts:
- A 2ml prefilled pod containing the mesh coil
- A 10ml refill container that supplies additional e-liquid to the pod
The larger container gradually feeds e-liquid into the 2ml pod as you vape. This allows the device to provide more use without requiring you to open a bottle, refill the pod manually or replace a separate coil.
Once both sections are empty, you remove the complete refill assembly and replace it with a new Hayati Rubik refill pack. The battery device itself can be recharged and reused.
This is an important distinction. The Hayati Rubik 7000 is not a traditional disposable vape, and it is not a fully refillable open-system pod kit. It sits between the two formats by offering disposable-style convenience in a rechargeable and replaceable system, which places it alongside the other prefilled pod kits sold in the UK since the disposable vape ban of 1 June 2025.
Design and Build Quality
The Rubik name comes from the device's compact, cube-inspired body.
Most high-puff prefilled kits use a tall rectangular shape. The Hayati Rubik is shorter and wider, giving it a more distinctive appearance and making it less likely to roll across a desk or table.
Despite the wider shape, it remains compact enough for normal pocket or bag storage. The rounded edges prevent it from feeling excessively bulky, while the solid body gives it a more substantial feel than a lightweight disposable.
The flavour-dependent gradient finishes add some visual interest without making the device overly complicated. The front display is integrated neatly into the body and gives the kit a more modern appearance.
Its build is practical rather than luxurious. You should not expect the finish or materials of an advanced metal pod mod, but it feels appropriate for a simple prefilled device intended for everyday carrying.
The pod and refill assembly connects securely when installed correctly. This helps prevent unnecessary movement and reduces the likelihood of the pod disconnecting while the device is in a pocket.
LED Display
The LED display is one of the most useful features of the Hayati Rubik 7000. Basic pod kits often rely on a small coloured light that only warns you when the battery is nearly empty. The Rubik provides clearer information, allowing you to check the remaining battery before leaving home or starting a longer journey.
The display provides an indication of the remaining e-liquid level. This is useful because the 10ml container is fitted inside the device and cannot always be judged as easily as a transparent refillable tank.
The display does not add complicated menus or controls. It provides practical information while allowing the device to remain completely inhale activated. For users who have previously experienced a vape unexpectedly running out of battery or e-liquid, this is a meaningful improvement rather than a purely decorative feature.
How the Auto-Refill System Works
The Hayati Rubik 7000 uses a 10ml container to keep the smaller 2ml pod supplied with e-liquid. You do not manually pour the liquid from one section to another. Once the refill pack is assembled and installed, the system manages the transfer automatically during use.
This arrangement offers several advantages. The coil remains supplied with e-liquid, reducing the risk of dry or burnt-tasting draws caused by an empty pod. The design allows the device to carry a larger overall e-liquid supply while retaining a compact mouthpiece and coil section.
The system is closed, so you cannot add your own bottled e-liquid. When the supplied e-liquid is exhausted, the complete Hayati Rubik refill pack must be replaced. That makes it extremely convenient, but it means you are limited to Hayati Rubik-compatible flavours and nicotine strengths.
Hayati Rubik 7000 Setup
Setting up the device is straightforward, although it is worth following the instructions supplied with your particular refill pack.
A typical setup process is:
- Remove the device and refill components from their packaging.
- Remove all protective seals, silicone plugs and transport caps.
- Connect the 2ml pod to its matching 10ml refill container.
- Insert the assembled refill into the device until it is fully seated.
- Allow a few minutes for the coil to absorb the e-liquid.
- Inhale through the mouthpiece to begin vaping.
There is no fire button to press and no wattage level to select.
Do not use the device if the packaging is damaged, the pod is leaking heavily or the components do not connect correctly. Always check the included user instructions because the exact arrangement of seals may differ between production versions.
Vaping Performance
The Hayati Rubik 7000 produces a mouth-to-lung draw.
Mouth-to-lung vaping involves drawing vapour into the mouth before inhaling it into the lungs. It is the style commonly preferred by former smokers and users of compact prefilled pod kits.
The fixed airflow provides a controlled and relatively tight inhale. It is not designed to create the large vapour clouds associated with direct-to-lung or sub-ohm devices.
In practical terms, the Rubik produces enough vapour to feel satisfying without becoming excessively cloudy. This makes it suitable for users who prefer a more discreet everyday vape.
Inhale activation responds automatically when you draw through the mouthpiece. The absence of a fire button makes the experience familiar to anyone moving from disposable vapes or cigarettes.
There are no power modes, boost settings or airflow adjustments. That keeps operation simple, although users who enjoy fine-tuning their draw may find it restrictive.
Mesh-Coil Flavour Performance
Each Hayati Rubik refill pod includes a built-in mesh coil. Mesh coils use a broader heating surface than basic wire coils. In a compact pod system, this can help distribute heat more evenly and produce fuller flavour without requiring high power.
Flavour delivery should be strongest when the refill is correctly installed and the coil has been given enough time to absorb the e-liquid. The auto-refill container helps keep the pod supplied throughout use, reducing the chance of the flavour suddenly becoming dry as the initial 2ml is consumed.
Sweet fruit and ice blends are particularly well suited to this type of coil. The cooling notes remain noticeable, while the fruit flavours generally feel clear enough for an all-day mouth-to-lung vape.
As with any prefilled pod, flavour intensity can gradually reduce as the coil and e-liquid reach the end of their usable life. Very frequent or unusually long draws place more demand on the coil and affect consistency.
The Rubik is not intended to provide the warmth, vapour density or customisable flavour output of an advanced refillable kit. Its focus is reliable flavour with minimal user involvement.
Is the 7,000-Puff Claim Realistic?
Hayati advertises the Rubik as delivering up to approximately 7,000 puffs from the combined 12ml e-liquid supply.
The phrase "up to" is important.
A puff count is an estimated laboratory or manufacturer figure rather than a guaranteed number for every user. Real-world results depend on:
- The length of each inhale
- How deeply you draw
- How frequently you vape
- Whether you take repeated draws without a break
- Battery and coil condition
- Manufacturing tolerances
A user taking short, controlled mouth-to-lung puffs may get closer to the advertised figure than someone taking long or frequent draws.
The 7,000-puff number should therefore be treated as a comparative capacity indicator. It tells you that the Rubik is designed to last considerably longer than a small-capacity disposable-style product, but it should not be interpreted as an exact puff counter.
Battery Life
The Hayati Rubik contains an 850mAh built-in battery.
That is a sensible capacity for a low-powered mouth-to-lung pod kit. Many moderate users should be able to cover a substantial portion of the day from one charge, although actual endurance depends on vaping frequency and draw length.
Heavier users may need to recharge before the end of the day. The LED display makes this easier to manage because it gives you advance notice rather than waiting for the battery to stop working.
The device charges through USB Type-C, so it can be topped up with a suitable cable and compatible power source.
The battery is built into the device and is not designed to be removed by the user. If it becomes damaged, overheats, swells or stops charging normally, discontinue use rather than attempting to repair it.
The charging cable may not be included in every package, so check the product description before ordering.
How Long Does the Hayati Rubik 7000 Last?
There are two separate factors to consider: battery life per charge and refill-pack lifespan.
The 850mAh battery may last many moderate users for most or all of a working day before recharging. Heavy use can reduce that duration.
The pod and refill container should last for several days for many users, but there is no fixed number of days. Someone who vapes occasionally will keep the same refill longer than someone who uses the device continuously.
You should replace the refill pack when:
- The e-liquid indicator shows it is empty
- Vapour production becomes unusually weak
- The flavour has disappeared
- The device begins producing a dry or burnt taste
- The pod is damaged or leaking excessively
Do not continue using an empty pod because this can overheat and damage the coil.
Hayati Rubik 7000 Flavours
The Hayati Rubik flavours range includes around 21 fruit, ice, mint, drink and confectionery-inspired flavours.
Common options include:
- Banana Ice
- Blue Razz Cherry
- Blue Razz Gummy Bear
- Blue Sour Raspberry
- Blueberry Cherry Cranberry
- Blueberry Raspberry
- Fresh Mint
- Hubba Bubba
- Juicy Peach
- Lemon Cola Ice
- Lemon Lime
- Mr Blue
- Pineapple Ice
- Red Apple Ice
- Strawberry Kiwi
- Strawberry Raspberry Ice
- Summer Dream
- Triple Mango
- Watermelon Ice
- Vim Ice
Availability can change, so the exact selection should be checked on the Royal Vapery product page.
Fruit-and-ice combinations dominate the range. Users who already enjoy Hayati's sweeter flavour profiles are likely to find familiar options, but those looking for tobacco flavours or unflavoured pods may find the selection limited.
Nicotine Strength and Throat Hit
Hayati Rubik 7000 refill packs are generally supplied with 20mg/ml of nicotine salt e-liquid. Nicotine salts are commonly used in prefilled mouth-to-lung pods because they provide a smoother inhale than many equivalent-strength freebase nicotine liquids.
The 20mg strength is likely to suit existing adult smokers and vapers who already use higher-strength nicotine salt products. It may feel too strong for light nicotine users or those accustomed to 3mg, 5mg or 10mg liquids.
At the time of writing, lower nicotine strengths do not appear to be widely available for the Rubik system. That is one of its biggest disadvantages.
Do not choose a higher nicotine strength simply because it is available. The most suitable strength depends on your previous smoking or vaping habits. A pharmacist, NHS Stop Smoking Service or specialist retailer can provide additional guidance.
Is the Hayati Rubik 7000 Reusable?
Yes. The battery device is reusable and rechargeable. Once the original e-liquid is finished, you do not need to discard the entire device. You replace the used pod and refill-container assembly with a compatible Hayati Rubik 7000 refill pack.
However, the individual pods are not manually refillable. You cannot open them and add bottled e-liquid. The correct description is therefore a reusable prefilled pod kit rather than a refillable open-system vape.
Hayati Rubik 7000 Pods
The device should only be used with genuine Hayati Rubik 7000 refill packs designed for the Rubik battery.
A replacement pack normally contains the 2ml pod and its matching 10ml refill container. The built-in coil is replaced at the same time, so you do not need to buy or install a separate coil.
Using the correct refill pack is important for fit, liquid transfer and electrical compatibility. Similar-looking Hayati pods from other device ranges may not work with the Rubik.
Before purchasing replacements, check that the product name clearly states Hayati Rubik 7000 compatibility.
Leak Resistance
The closed refill system is designed to minimise leaking and remove the mess associated with pouring bottled e-liquid.
However, no pod system is completely immune to condensation or occasional seepage. Small amounts of moisture around the connection can sometimes result from condensed vapour rather than a failed pod.
You can reduce potential leaking by:
- Installing the pod and container correctly
- Removing every transport seal
- Keeping the device upright when possible
- Avoiding prolonged exposure to heat
- Not leaving it inside a hot vehicle
- Wiping the connection area during pod changes
- Replacing damaged refill packs immediately
Do not use a refill pack that is cracked or releasing a significant amount of liquid.

Who Should Buy the Hayati Rubik 7000?
The Rubik 7000 is best suited to adult vapers who prioritise convenience.
It is particularly relevant for existing disposable-style vape users who want to move to a rechargeable system without learning how to fill pods, change coils or adjust wattage.
Former smokers may appreciate its straightforward mouth-to-lung draw, inhale activation and 20mg nicotine salt strength.
It may be suitable for:
- Existing Hayati users
- Adults switching from disposable vapes
- Former smokers who prefer a tighter draw
- Users who do not want to handle bottled e-liquid
- People who want a compact everyday device
- Vapers who prefer clear battery information
- Users looking for more capacity than a basic pod
Who Should Avoid it?
The Hayati Rubik will not suit everyone.
Consider a refillable or adjustable pod kit instead if you want:
- Nicotine strengths below 20mg
- Nicotine-free e-liquid
- Adjustable airflow
- Variable wattage
- A loose restricted-direct-lung draw
- Large vapour production
- The freedom to use any bottled e-liquid
- Replaceable coils
- Tobacco or specialist e-liquid flavours
It is not suitable for non-smokers, children, pregnant users or anyone advised by a healthcare professional to avoid nicotine.
Hayati Rubik 7000 vs Hayati Pro Max Plus 6000
The Hayati Rubik 7000 and Hayati Pro Max Plus 6000 are both rechargeable prefilled pod kits built around simplicity.
The Pro Max Plus uses a more conventional upright body, while the Rubik uses a shorter cube-shaped design. Both offer inhale activation, mesh-coil pods, rechargeable batteries and a prefilled pod-plus-container system.
The Rubik has the higher advertised puff figure at up to 7,000 compared with approximately 6,000 for the Pro Max Plus. The practical difference may be less noticeable because actual puff count depends on individual use.
Choose the Rubik if you prefer its compact square shape, e-liquid display and slightly higher advertised capacity.
Choose the Pro Max Plus if you prefer a slimmer, more traditional form factor or want access to its particular flavour range.
Hayati Rubik 7000 vs Hayati Pro Ultra Plus 25000
The Pro Ultra Plus 25000 is aimed at users wanting significantly greater advertised capacity and the ability to switch between two flavours.
The Rubik 7000 is smaller, simpler and easier to carry. It provides one flavour at a time and is likely to appeal to users who do not need a dual-flavour mechanism.
The Ultra Plus is more suitable for heavy users who value capacity and flavour switching over compactness.
Choose the Rubik 7000 for:
- A smaller everyday device
- A single straightforward flavour
- Easier pocket storage
- Lower initial commitment
Choose the Pro Ultra Plus for:
- A much higher advertised puff count
- Two-flavour switching
- Longer periods between refill changes
- A larger and more feature-focused device
Is the Hayati Rubik 7000 Worth Buying?
The Hayati Rubik 7000 is worth considering if you want a rechargeable pod kit that operates almost like a disposable vape.
It offers a useful balance between capacity and portability. The battery can be recharged, the refill assembly can be replaced, and the user does not need to maintain the coil or handle loose e-liquid.
The LED display is genuinely useful, while the cube-shaped body gives it an identity of its own in a crowded market.
Its value depends heavily on whether 20mg nicotine and fixed airflow suit you. If they do, the Rubik delivers a convenient and low-maintenance experience. If they do not, the device offers no meaningful adjustment.
The refill-pack price should be considered when comparing long-term value. Look at the cost per complete refill rather than judging the starter kit price by itself.
Final Verdict
The Hayati Rubik 7000 succeeds by keeping the vaping experience uncomplicated.
Its 2ml pod and 10ml auto-refill container provide a useful 12ml total supply without requiring manual refilling. The 850mAh battery, USB-C charging and clear display make it practical for daily use, while the fixed mouth-to-lung draw should feel familiar to users of cigarettes and disposable-style vapes.
The cube-shaped design is more than a visual gimmick. It makes the Rubik compact, stable on flat surfaces and noticeably different from the many tall prefilled kits available in the UK.
There are limitations. You are restricted to compatible prefilled refills, the nicotine strength is generally fixed at 20mg, and there are no airflow or power controls. The 7,000-puff figure should be understood as an advertised maximum rather than a guaranteed result.
For its intended audience, however, these limitations may not be significant. The Rubik is made for people who want to insert a refill, monitor the display and inhale without dealing with settings or maintenance.
For adult vapers looking for a compact, rechargeable and easy-to-manage Hayati device, the Hayati Rubik 7000 is a strong everyday option.

FAQs Hayati Rubik 7K
Yes. The Hayati Rubik battery device can be recharged and reused with compatible Hayati Rubik 7000 refill packs. The individual prefilled pods are not intended to be filled manually with bottled e-liquid.
Yes. Compatible Hayati Rubik 7000 refill packs can be purchased separately. A refill set normally includes a 2ml prefilled pod and a matching 10ml auto-refill container. Check the product name carefully because pods made for other Hayati devices may not be compatible.
It is advertised to provide up to approximately 7,000 puffs from its combined 12ml e-liquid capacity. Actual results depend on draw length, vaping frequency and individual usage.
There is no fixed number of days. Moderate users may keep one refill for several days, while heavy users will finish it sooner. The advertised puff count is a maximum estimate rather than a guarantee.
Hayati Rubik refill packs are generally supplied with 20mg/ml nicotine salt e-liquid. Lower strengths may not be available, so check the individual product listing before buying.
The LED display is designed to provide battery and e-liquid information, making it easier to estimate when charging or replacement will be required.
No. It uses fixed airflow designed to produce a controlled mouth-to-lung inhale.
No. The device is designed for closed, prefilled Hayati Rubik refill packs. Attempting to open or manually refill the pods may cause leaking, damage or unsafe operation.
The e-liquid indicator may show that the refill is depleted. Other signs include reduced vapour, little or no flavour, and a dry taste. Stop using the pod if it produces a burnt taste.
A burnt taste can occur if the coil has not absorbed enough liquid, the refill is empty, the pod is damaged or repeated long draws have overheated the coil. Allow a newly installed refill to stand for a few minutes before use. Replace it if the burnt taste continues.
Connect a suitable USB-C cable to the charging port and use a compatible power source. Monitor the device while it charges and disconnect it when charging is complete. Do not use a damaged cable or charge a device that is leaking, swollen or unusually hot.
A USB-C cable may not be included with every Hayati Rubik 7000 package. Check the Royal Vapery product description to confirm what is supplied.
It can be suitable for adult beginners who already smoke or use nicotine because there are no buttons, menus or coils to install. However, its 20mg nicotine strength may be too strong for some users.
UK vaping rules restrict tanks to 2ml, nicotine-containing refill containers to 10ml and nicotine strength to 20mg/ml. The Rubik uses a 2ml pod and a separate 10ml refill container. Purchase only genuine products from a reputable UK retailer and check that the product has the required packaging and notification information.
The best flavour depends on personal preference. Watermelon Ice and Pineapple Ice may appeal to users who enjoy cooling fruit flavours, while Triple Mango and Juicy Peach provide sweeter fruit profiles. Fresh Mint is a simpler option for users who do not want a mixed-fruit flavour.
Current UK health guidance states that vaping exposes users to fewer toxins and at lower levels than smoking cigarettes, but it is not harmless. The benefit applies most clearly when an adult smoker switches completely rather than continuing to smoke and vape together.
Non-smokers should not start using nicotine vapes. The Hayati Rubik generally contains 20mg nicotine salt, which is addictive and intended for existing adult smokers or vapers.
This product contains nicotine, which is an addictive substance. Sale is restricted to adults aged 18 and over. Vaping is less harmful than smoking, but it is not risk-free.
