How the Feoba Treo 33K stays legal in the UK

This is genuinely important to understand, especially given how many high puff vapes sold in the UK are non-compliant imports.

Under the Tobacco and Related Products Regulations 2016, enforced in Great Britain by Trading Standards and the Medicines and Healthcare products Regulatory Agency (MHRA), no single e-cigarette tank or pod may hold more than 2ml of e-liquid, and nicotine strength may not exceed 20mg/ml. These rules come from the European Tobacco Products Directive (TPD) framework retained in UK law after Brexit.

The Feoba Treo 33K achieves its 33,000 puff count through a sealed modular architecture. The pod itself holds exactly 2ml, within the legal limit. The two sealed 6ml refill containers replenish the pod as it empties, with no single reservoir exceeding 2ml at any point in active use. The device is MHRA notified under FEOBAWAVE LIMITED and meets all requirements outlined on the MHRA e-cigarette guidance hub.

For full regulatory context, you can read the Tobacco and Related Products Regulations 2016 and cross reference with GOV.UK guidance on vaping regulation. Trading Standards guidance for UK retailers and consumers is also available through the Chartered Trading Standards Institute.

Feoba Treo 33K flavours, full breakdown with sensory descriptions

We have tested every flavour in this range in house, checking consistency of flavour delivery across the full pod life, throat hit at 20mg nicotine salt strength, vapour density on the exhale, and accuracy of the flavour profile against what is described on the label.

Slush and ice collection

• Blue Slush 
  This one opens cold. The inhale is sweet, almost candy like, with a blue slushie character that is clearly identifiable. On the exhale the cooling hits the back of the throat with a clean finish. Vapour density is medium to high. It is not aggressively icy, which makes it easy to chain vape through a morning without irritation. Reliable and popular for good reason.
  
  
• Pink Slush 
  A candy berry mix that sits somewhere between bubblegum and raspberry on the palate. The cooling element is more subtle here than on Blue Slush, giving a warmer berry undertone that transitions into a light chilled exhale. Throat hit is smooth at 20mg. A good choice if you want sweetness without an overwhelming menthol blast.
  
  
• Red Slush 
  Rich, deep, dark berry on the inhale. Think frozen red berry ice lolly rather than a lighter fruit drink. The icy exhale has real presence here, more so than Pink Slush, giving a satisfying contrast between the warm berry inhale and cold finish. One of the standout flavours in the slush range.
  
  
• Grape Ice 
  Sweet table grape on the inhale with a crisp menthol exhale. The grape is accurate rather than artificial, which is unusual in this format. The menthol level is mid-range, cooling without being clinical. Works very well as an all day vape.
  
  
• Mango Ice 
  Juicy, ripe mango on the draw with a clean cooling finish on the exhale. The mango character stays true through the full pod rather than fading to a generic fruit note, which is a testament to the mesh coil delivering consistent temperature. A consistently top selling flavour at this site.
  
  
• Watermelon Ice 
  Light, sweet watermelon sweetness on the inhale, refreshing and summery. The icy finish is pronounced on this one, making it particularly refreshing. Vapour is lighter than the berry variants. A great afternoon vape.

Tropical and exotic blends

• Caribbean Crush 
  A blended tropical mix that opens with pineapple and then layers in passionfruit and mango notes. It does not taste like any single fruit, which is intentional. The overall effect is a sun drenched, slightly sour fruit punch on the inhale with a warm, sweet exhale. No cooling element here.
  
  
• Pineapple Lemon Burst 
  Sharp on the inhale. This one hits with citrus immediately, a bright lemon zest that fades quickly into pineapple sweetness. The contrast makes it feel almost fizzy on the palate. A high energy flavour that works well as a daytime option when you want something that wakes the senses.
  
  
• Sour Pineapple Ice 
  The sourness on this is genuine and upfront. Pineapple with a tart acidic edge on the inhale, followed by a cool exhale that dials back the intensity. If you like sour sweets this will be very familiar. The cooling prevents it from being overwhelming.
  
  
• Tropical Sour Ice Blast 
  The most intense option in the tropical range. This is layered sour tropical fruits (think passion fruit, guava, mango) with a sharp sour hit and a pronounced icy finish. Not for those who find sour flavours challenging, but an excellent choice if you want something genuinely different from the standard fruit vape.

Berry fusions

• Mr Blue 
  A complex forest berry blend covering blueberry, blackberry, and raspberry with a cooling finish on the exhale. The blueberry leads the inhale, the blackberry adds depth mid-palate, and raspberry brightness comes through on the exit. The cooling element is moderate. One of the more sophisticated flavour profiles in this range.
  
  
• Blueberry Sour Raspberry 
  Sweet blueberry upfront with a raspberry tartness that sharpens on the mid-inhale. The balance between sweetness and sourness is well calibrated. Not aggressively sour, just enough to make it interesting. Works as a lower effort all day vape.
  
  
• Strawberry Raspberry Cherry Fusion 
  Three berries working together rather than competing. The strawberry provides the base sweetness, raspberry adds brightness, and cherry gives a slight floral depth to the exhale. Vapour is dense and the flavour carries well. An excellent choice for ex-smokers who prefer sweeter, familiar profiles.
  
  
• Strawberry Cranberry Cherry
  A slightly more complex and adult tasting version of the strawberry berry blends. The cranberry introduces a real tartness that the cherry softens. This one has more sophistication than a standard strawberry vape and suits vapers who want fruit without the candy sweetness of simpler blends.
  
  

Candy and unique profiles

• Gummy Bear 
  Exactly what it says. Mixed chewy fruit sweet, covering green apple, red berry, lemon, and orange in the way a bag of mixed gummies tastes. Sweet and uncomplicated. The vapour is warm and the exhale has a gentle sweetness that lingers briefly. A crowd pleaser and consistently popular.
  
  
• Fizzy Cherry 
  Sweet cherry with a sparkling, slightly acidic soda character on the exhale. This is genuinely one of the more creative profiles in the range. The fizzy note is subtle, adding effervescence rather than sourness, and the cherry base is soft and realistic. A good conversation starter flavour.
  
  
• Xtreme Sour Apple 
  Sharp green apple on the inhale with an intense sour hit that builds quickly. This is the most demanding flavour in the range in terms of acidity. If you like sour apple sweets you will find it accurate and fun. If sourness is not your thing, steer toward the gentler options.

How to use the Feoba Treo 33K

Step 1. Unbox and check. Remove the device from packaging and confirm the pod is seated correctly in the battery body. The connection should click or sit flush. Check that the USB Type C port is clear of any protective film before first use.

Step 2. Charge before first use. Connect the USB Type C cable to a standard USB wall adapter (5V, maximum 1A recommended, avoid fast chargers designed for modern smartphones). Allow the device to reach full charge before your first session. Charging time from flat is approximately 45 to 60 minutes.

Step 3. Draw and vape. The Feoba Treo 33K is draw activated with no fire button. Simply put the mouthpiece to your lips and inhale slowly and steadily. For mouth to lung vaping, draw the vapour into your mouth first before inhaling to your lungs. This mirrors the action of smoking a cigarette and delivers nicotine more efficiently at 20mg salt strength.

Step 4. Refill when prompted. When flavour begins to fade or vapour volume drops noticeably, the pod is running low. Remove the empty sealed refill container and attach the next one following the instructions in the kit. The pod remains in place and the 2ml capacity is replenished without exceeding the legal limit.

Step 5. Recharge as needed. When the battery level drops (indicated by a dim or flashing LED on some units), reconnect via USB Type C. You do not need to wait for the battery to fully deplete between charges. The 1100mAh battery is designed for partial charge cycling.

Frequently asked questions

1. Is the Feoba Treo 33K legal to buy in the UK?

Yes, the Feoba Treo 33K is fully legal to buy and use in the UK. It is MHRA notified under FEOBAWAVE LIMITED and meets all requirements of the Tobacco and Related Products Regulations 2016. Its pod capacity does not exceed 2ml and nicotine strength does not exceed 20mg/ml, the maximum permitted under UK law. It is also a rechargeable device, not a single use disposable, making it compliant with the UK disposable vape ban effective 1 June 2025.

2. How does the Feoba Treo 33K get 33,000 puffs without breaking the 2ml rule?

The 33,000 puff total is achieved through a sealed modular refill system. The active pod holds 2ml at any given time, which is within the legal UK limit. When the pod runs low, a sealed 6ml refill container replenishes it in stages. No single chamber ever exceeds 2ml during active vaping. The system uses multiple refill containers to extend the overall liquid volume across the kit life.

3. What nicotine strength is the Feoba Treo 33K?

The Feoba Treo 33K uses 20mg/ml nicotine salt, which is the maximum permitted strength under the Tobacco and Related Products Regulations 2016. Nicotine salt (nic salt) formulations use benzoic acid to reduce harshness at higher strengths, making the throat hit noticeably smoother than freebase nicotine at the same concentration. This makes 20mg nic salt particularly suitable for ex-smokers transitioning from cigarettes.

4. How long does the Feoba Treo 33K last compared to a standard disposable vape?

A standard 600 puff disposable such as the Elf Bar 600 or Lost Mary BM600 is typically equivalent to around 20 to 40 cigarettes depending on draw length. The Feoba Treo 33K at up to 33,000 puffs is roughly equivalent to 55 standard 600 puff disposables under the same conditions. Actual puff count varies depending on your individual draw length and frequency of use.

5. Can I refill the Feoba Treo 33K with my own e-liquid?

No. The refill containers are sealed units and are not designed to be opened or refilled with third party e-liquid. Attempting to open or bypass the sealed system may damage the device and could compromise the MHRA notified safety profile. Only use the original sealed Feoba Treo 33K refill containers.

6. How do I charge the Feoba Treo 33K?

The Feoba Treo 33K charges via the built in USB Type C port on the battery body. Use a standard 5V USB wall adapter and a quality USB Type C cable. Avoid using high wattage fast chargers designed for modern smartphones, as these may deliver more current than the battery management system is rated for. Full charge from flat takes approximately 45 to 60 minutes.

7. Is the Feoba Treo 33K suitable for beginners?

The Feoba Treo 33K is a mouth to lung (MTL) device, which means the inhalation style closely mimics smoking a cigarette. This makes it a very natural transition for ex-smokers. The 20mg nicotine salt strength delivers effective nicotine satisfaction with a smooth draw. It is user friendly in operation, as there are no wattage settings, no coil priming steps, and no buttons to press. However, 20mg is a high nicotine strength. If you are new to vaping and were a light smoker, you may prefer a lower strength option. See our nicotine strength guide for more detail.

8. What happens when the pod is empty on the Feoba Treo 33K?

When the pod is empty, you attach the next sealed refill container from your kit. Detailed instructions are included in the product packaging. The device is designed so that the pod stays in place during refilling, maintaining the 2ml capacity limit at all times. When all refill containers in the kit have been used and the pod is empty, you purchase a replacement pod kit or a replacement pod pack available separately on this site.
