Hayati Pro Max E-Liquid 100ml 50/50 – Rainbow

Hayati Pro Max 100ml 50/50 in Rainbow: the sweet-shop classic, reimagined for smaller devices

Rainbow is one of those flavours that needs almost no introduction. Say the word to anyone who grew up raiding the pick and mix, and their mind goes straight to a fistful of chewy fruit sweets, every colour tumbling together into one bright, sugary mouthful. That is exactly the memory the Hayati Pro Max Rainbow blend is chasing, and in this 50/50 version it does it in a way that suits smaller pod devices, refillable pods and starter kits beautifully. This is a large 100ml nicotine-free shortfill, so you get plenty of liquid to work with, and the balanced 50/50 ratio is the key detail that shapes the whole experience.

The 50/50 blend means an even split of the two main base ingredients, which gives you a tighter, more mouth-to-lung style draw, a slightly firmer feel on the inhale, and a flavour that lands crisp and defined rather than soft and cloudy. For a sweet, fruity profile like Rainbow, that crispness is a genuine advantage, because every individual fruit note stays sharp and readable instead of blurring together.

Tasting the rainbow, note by note

The first inhale is pure nostalgia. It opens with a bright burst of mixed fruit sweetness, that instantly recognisable candy-shop tang that sits somewhere between strawberry, orange, lemon and something tropical. In the 50/50 format this opening is punchy and clean, hitting the front of the palate with real definition. It is sweet, unmistakably so, but it is the fun kind of sweet, playful rather than heavy.

Across the mid vape, the individual fruits start to reveal themselves. You catch the zip of citrus, the roundness of red berry, and a softer tropical note weaving underneath. Because the 50/50 ratio keeps the vapour on the crisper side, these layers stay distinct, so the flavour feels busy and lively in the best sense. It genuinely tastes like a handful of different sweets rather than one flat, generic fruit. There is a gentle chewiness to the character too, that candy quality that separates a proper Rainbow blend from a simple fruit juice mix.

The exhale and aftertaste keep things bright and clean. As you breathe out, the sweetness lingers just long enough to leave a pleasant fruity film on the palate, then clears without turning cloying. There is a mild tang on the finish, a little tartness that stops the sugar becoming too much, and it leaves you ready for the next draw. In the 50/50 build the finish is neat and controlled, which is a big part of why this version works so well as an all-day vape rather than an occasional treat.

Who it suits and when it shines

This flavour is made for people who love a sweet, uncomplicated, feel-good vape. It has broad appeal, and it is particularly good for anyone using a smaller pod system or a mouth-to-lung setup, since the 50/50 ratio is designed to run smoothly in those devices. If you have moved to a compact refillable kit and want a flavour with real personality, Rainbow delivers it without needing a big cloud-chasing machine.

• Great for: pod kits, mouth-to-lung devices and refillable starter setups where a firmer draw suits the hardware.
• Best occasion: daytime and social settings, when you want something cheerful and easy going that keeps your mouth feeling fresh.
• Best mood: upbeat and casual, the kind of flavour that suits a good day rather than a quiet, reflective one.

Who might want to skip it? If you dislike sweet flavours, or you specifically want something cooling, herbal or tobacco-like, Rainbow will feel far too sugary for you. It wears its candy heart on its sleeve and makes no apology for it.

How it compares and what to rotate with

Compared with a single-fruit e-liquid such as a straight strawberry or a lone mango, Rainbow is busier and more playful, with several fruits jostling together instead of one clean note. Compared with an iced fruit blend, it is warmer and sweeter, with no menthol chill to cut through the sugar. That makes it a brilliant everyday flavour, but it also means the sweetness can build up if you vape nothing else for days on end.

• Rotate it with a sharp single fruit, such as a lemon or a berry, to give your palate a cleaner counterpoint.
• Pair it with an iced or menthol liquid for moments when you want cooling refreshment instead of candy warmth.
• Keep a plain or lightly sweet flavour in the rotation so Rainbow stays a bright highlight rather than becoming your baseline.

Sweet candy flavours are the ones most prone to palate fatigue, so a little variety keeps Rainbow tasting as fun on day thirty as it did on day one.

Practical notes and getting the truest taste

Because this is a 100ml nicotine-free shortfill, you have flexibility. You can vape it as it comes for a completely nicotine-free experience, or add nicotine shots to reach the strength you prefer, always keeping within the UK limits. Give the bottle a good shake before filling, and if you add anything to it, let it stand for a short while so everything blends evenly. That small step helps the fruit notes marry together instead of tasting slightly separated.

For the truest Rainbow taste, run it in a device suited to a 50/50 liquid and avoid pushing your coil too hot, since excessive heat can flatten the delicate top fruit notes and mute the candy sparkle. Fresh coils always show off a sweet fruity blend best, so change yours before the flavour starts to dull. Store the bottle upright, sealed, somewhere cool and dark, and keep it well away from children and pets at all times.

Frequently asked questions

What does Rainbow actually taste like?

It tastes like a mixed bag of chewy fruit sweets, a blend of berry, citrus and tropical notes with a candy sweetness running through all of it. In the 50/50 version those individual fruits come across crisp and well defined rather than blurred together.

Is the 50/50 version better for pod kits?

Yes. The balanced 50/50 ratio gives a firmer mouth-to-lung draw and suits smaller pod systems and starter kits far better than a high-VG liquid would. If your device is compact and made for tighter draws, this is the ratio to choose.

Does it come with nicotine?

This is a nicotine-free 100ml shortfill, so it contains no nicotine as sold. You can vape it as it is, or add nicotine shots to reach your preferred strength within the legal UK limit. Nicotine products are strictly for over-18s.
