Big puff pod kits have become a popular choice for UK vapers who want longer use without constantly replacing devices. Since disposables were restricted, many customers have been looking for something that keeps the same flavour quality but lasts significantly longer.

The Hayati Ultra Plus 25K Prefilled Vape Kit is designed to do exactly that. With a dual flavour twist system and a crisp LED screen showing battery life and puff count, it offers more control than a standard prefilled pod kit while keeping the setup simple.

At Go Smoke Free, we put this latest Hayati vape kit through proper day-to-day testing. That meant using it as a primary device, switching flavours regularly and running the battery through full charge cycles. The aim was straightforward: does it stay consistent over time, and does it genuinely suit regular, heavier use?

Before looking at performance, it’s important to understand how this device is structured. Unlike smaller prefilled pod kits, the Ultra+ 25K combines a compliant 2ml mesh coil pod with two 10ml auto-refilling e-liquid tanks. This gives a total of 22ml of 20mg/ml nicotine salt vape liquid while remaining fully TPD compliant, as only 2ml is active in the chamber at any one time.

Device Overview:

• Up to approximately 25,000 puffs (usage dependent)
• 850mAh built-in rechargeable battery
• LED battery percentage display & puff counter
• 2ml prefilled dual mesh coil pod
• 2 × 10ml auto-refilling e-liquid tanks
• 22ml total e-liquid capacity
• 20mg/ml nicotine salt
• Inhale activated
• Turbo-charging USB Type-C port (cable not included)
• Dimensions: 53.5mm × 107mm × 29.3mm
• Replaceable prefilled pod system

The defining feature here is the dual flavour system. Both refill tanks are installed at the same time, and you switch between them by pulling up and rotating the mouthpiece. It’s a mechanical selector rather than an electronic switch, which keeps the process simple and reliable.

Extended-capacity devices can sometimes feel oversized, but the Ultra+ 25K manages to stay compact given what it houses internally. The dimensions make it slightly larger than 600-style kits, though the added size reflects the 850mAh battery and dual 10ml tanks rather than unnecessary bulk. In hand, it feels balanced and solid. There are no loose parts, no panel movement, and the twist mechanism has a deliberate resistance that prevents accidental switching.

The finish is smooth and durable, resisting fingerprints during daily carry. The transparent e-liquid viewing section is a practical touch, allowing you to monitor remaining liquid easily without guesswork. The LED display is clear and functional. It shows battery percentage precisely and the puff counter gives real-time usage feedback. Overall, the build quality feels dependable rather than disposable.

Despite its capacity, the Ultra+ 25K vape kit remains straightforward to assemble. The refill pack includes the 2ml built-in mesh pod and two 10ml refill tanks. After removing silicone bungs and protective stickers, the components align easily and click into place without excessive force.

Once assembled, allow a few minutes for the coil to saturate fully before taking your first puff. This step ensures proper flavour delivery from the start and protects the mesh coil from premature wear. Operation itself is simple, the device is inhale activated, so there are no firing buttons to press. Switching flavours involves lifting and rotating the mouthpiece, isolating one tank at a time. There is no complicated menu system, and no adjustment settings to navigate. It’s designed to feel intuitive from the first use.

Flavour consistency is where larger-capacity pod systems often struggle. With 22ml of e-liquid available, the mesh coil needs to remain stable over extended use. The Ultra+ 25K uses a dual mesh coil structure, and in our testing, flavour clarity remained steady throughout multiple refill cycles. We tested a few of the flavours and gave you our verdict of them:

Kiwi Banana: Creamy with a subtle tang. The banana comes through first on the inhale, adding smooth body and natural sweetness, while the kiwi follows with a light sharpness that lifts the profile and stops it from becoming overly rich.

The balance between the two feels well judged. The creaminess stays smooth rather than heavy, and the kiwi keeps the flavour fresh across extended use. It’s an easy all-day option for those who prefer softer fruit blends with a little contrast.

Mr Blue: A darker berry blend with a clean icy edge. The mixed berries lead on the inhale with a slightly sweet, almost jam-like depth, followed by a crisp cooling finish that sharpens the profile without overwhelming it.

The balance between fruit and ice is well judged. The cooling remains steady rather than building harshly over time, and the berry notes stay defined instead of blending into a generic sweetness.

Blue Razz Pineapple: Sweet blue raspberry hits first, delivering a bright, candy-style tang on the inhale. The pineapple follows on the exhale, adding a tropical lift that softens the sharper blue razz edge.

It’s a lively combination that feels fresh rather than artificial. The mesh coil keeps both elements clear and separated, so the flavour doesn’t become muddled even with regular switching between pods.

Cherry Ice / Peach Mango: Cherry Ice delivers a rich, slightly darker cherry flavour with a clean cooling finish that sits neatly on the exhale. It feels smooth rather than sharp.

Switching to Peach Mango softens the profile. The peach brings gentle sweetness, while the mango adds a fuller tropical body. The contrast between the two makes this pairing ideal for alternating throughout the day without flavour fatigue.

Grape GB / Strawberry GB: Grape GB leans sweet and juicy, with a confectionery-style grape note that remains smooth rather than syrupy and the mesh coil keeps it clean and consistent.

Strawberry GB is lighter and brighter, with a sweet strawberry inhale and a subtle bubblegum-style finish. Rotating between the two keeps the sweetness balanced without becoming overwhelming.

Fresh Mint: Fresh Mint offers a crisp, clean cooling profile with no added sweetness. The inhale feels sharp and refreshing, while the exhale leaves a steady mint finish. It works particularly well as an all-day option for those who prefer straightforward menthol-style flavours without fruit blends.

Across all flavours tested, there was no significant flavour drop-off near depletion. Provided the device was set up correctly and allowed to saturate initially, the vape remained smooth and consistent.

The 1250mAh built-in battery is one of the stronger features of this device. For moderate to heavier users, it comfortably supports full-day use without constant recharging. Even under regular usage, the battery percentage drops steadily rather than rapidly, which reflects good power management from the internal chipset.

Charging via the turbo USB Type-C port restores power efficiently. During testing, the device reached full charge within roughly an hour. As stated, the charging cable is not included and must be purchased separately if required. Importantly, battery capacity feels well matched to the e-liquid volume. You are unlikely to be left with unused liquid due to premature battery depletion.

Vapour production remains consistent throughout the battery cycle, delivering a smooth mouth-to-lung draw designed to replicate a cigarette-style inhale.

With approximately 25,000 puffs available per full vape kit, the Ultra+ 25K represents strong value compared to repeatedly purchasing smaller devices.

When compared to 600-puff disposables or compact pod kits, the cost per puff becomes significantly lower over time. The replaceable Hayatai Pro Ultra+ 25K refills also means you only change the e-liquid components rather than discarding the entire battery device.

For vapers who like switching between flavours during the day, the dual tank design also reduces the need to carry multiple devices, adding practical value beyond just puff count.

The Hayati Pro Ultra Plus 25K Pod Kit delivers exactly what a big puff pod kit should: reliability, extended use and consistent flavour performance. The 1250mAh battery provides genuine all-day endurance and the crisp LED battery display and puff counter add clarity. The dual flavour twist system is practical rather than gimmicky, allowing seamless switching without carrying additional devices.

From customer feedback, similar themes appear repeatedly.

Titus described it as “the best by far” after trying many disposables, highlighting flavour quality and long-term reliability. Debbie praised the banana and strawberry profile and noted how long the charge holds. Ashley commented on the battery longevity compared to previous disposables while Sydney described it as a “fantastic product that lasts ages with good flavour.”

That consistency in real-world feedback reinforces what we experienced during testing.

For moderate to heavier vapers who want extended capacity, flavour variety and fewer interruptions throughout the day, this device performs strongly within its category. If you’re looking for a long-lasting, dual-flavour prefilled pod kit with strong battery life and reliable flavour delivery, it’s one of the more balanced options available in the big puff segment.
