Hayati Pro Max E-Liquid 100ml 70/30 – Rainbow

Hayati Pro Max 100ml 70/30 in Rainbow: the same candy soul, dialled up for clouds

Rainbow is a familiar friend, that big, joyful mouthful of mixed fruit sweets that so many vapers reach for when they want something bright and easy to love. What changes everything in this version is the ratio. This is the 70/30 build of the Hayati Pro Max Rainbow shortfill, a large 100ml nicotine-free bottle weighted heavily towards the thicker base ingredient, and that single detail transforms how the flavour behaves. If you have tried a balanced blend of the same fruit and want to understand why the higher VG version feels so different, this is where the story gets interesting.

A 70/30 ratio means more of the smooth, cloud-producing base and less of the thinner, sharper one. In practice that gives you a softer, warmer inhale, bigger and denser vapour, and a rounder, more enveloping flavour delivery. Where a balanced Rainbow lands crisp and defined, the 70/30 version wraps the same fruit notes in a plusher, cloudier body. It is the difference between hearing a song on tinny earbuds and hearing it fill a room.

How the flavour unfolds in a high-VG build

The first inhale is noticeably smoother and softer than a sharper mix. The candy sweetness is all there, but it arrives gently, spreading across the palate on a cushion of thick vapour rather than snapping at the tip of your tongue. It feels generous and mellow, the fruit sweetness blooming slowly rather than hitting all at once. For anyone who finds high-tang liquids a little harsh, this rounded opening is a real comfort.

Through the mid vape, the higher VG does something clever with Rainbow. Instead of keeping every fruit sharply separate, it blends them into one lush, cohesive candy wave. You still catch the berry, the citrus and the tropical hints, but they melt together into a smoother, sweeter whole that coats the mouth. The density of the vapour makes the flavour feel richer and more filling, so a single draw carries a lot more presence. This is the version that rewards a slow, deep, direct-to-lung pull, letting those big clouds carry the sweetness right through the exhale.

On the exhale and aftertaste, the 70/30 build really shows its hand. The vapour billows out thick and satisfying, and the sweetness lingers longer and softer than it would in a crisper liquid. The finish is rounded and mellow, with the fruit candy character fading gently rather than snapping shut. There is a faint syrupy quality to the aftertaste, in the best way, a plush sweetness that stays with you for a while. It is a warmer, more indulgent finish than the sharper ratio delivers.

Who it suits and when to reach for it

This version is built for cloud chasers and direct-to-lung vapers. If you run a sub-ohm device, love big billowing vapour and want a sweet flavour that fills every draw, the 70/30 Rainbow was made for you. The higher VG needs the airflow and power of a proper sub-ohm setup to shine, and in the right hardware it produces the kind of dense, flavourful clouds that make sub-ohm vaping so satisfying.

• Great for: sub-ohm tanks and direct-to-lung kits with plenty of airflow and power.
• Best occasion: relaxed, unhurried sessions at home or with friends, where big clouds and a mellow sweet flavour are the whole point.
• Best mood: laid back and indulgent, when you want to sink into a flavour rather than take a quick sharp hit.

It is not the right pick for everyone. If you use a small pod kit or a tight mouth-to-lung device, this thick liquid will struggle to wick properly and can leave you with dry, muted draws. Anyone who prefers a firmer draw and crisp, sharply separated fruit notes will be happier with the balanced ratio instead.

How it compares and what to rotate with

Set side by side with the 50/50 Rainbow, this version is softer, sweeter, cloudier and more blended, trading crisp definition for plush body and vapour. Against an iced fruit liquid it is warmer and rounder, with no cooling snap. Because the sweetness is so enveloping here, palate fatigue can creep in even faster than with a sharper blend, so rotation matters.

• Alternate it with a sharp, high-VG single fruit to give your palate a cleaner, more focused break.
• Pair it with an iced or menthol sub-ohm liquid when you want the same big clouds but a cooling reset.
• Keep a less sweet blend in your rotation so the plush Rainbow candy stays a treat rather than a constant.

Practical notes for the best clouds and flavour

As a 100ml nicotine-free shortfill, this bottle gives you room to customise. Vape it nicotine-free straight from the bottle, or add nicotine shots to your preferred strength within the UK legal limit, then shake well and let it settle so the flavour integrates fully. High-VG liquids benefit from a slightly longer settle than thinner ones, so a little patience pays off.

To get the truest, cloudiest Rainbow, use a sub-ohm coil with enough wattage and give the liquid a moment to soak into a fresh coil before you start, since thick liquids need time to wick. Prime new coils properly to avoid dry hits, take smooth deep draws rather than short sharp ones, and keep your airflow reasonably open so the dense vapour can breathe. Store the bottle upright and sealed, somewhere cool and dark, and keep it out of reach of children and pets.

Frequently asked questions

How is the 70/30 Rainbow different from the 50/50?

The flavour is the same mixed fruit candy at heart, but the 70/30 ratio makes it smoother, sweeter and cloudier, blending the fruits into one lush wave. The 50/50 keeps each fruit crisper and firmer. It really comes down to whether you want big clouds and roundness or sharper definition and a tighter draw.

Can I use this in a small pod device?

It is not recommended. This high-VG liquid is thick and designed for sub-ohm, direct-to-lung setups. In a small pod kit it can struggle to wick and may give dry, weak draws. For pod devices, the 50/50 version is the better match.

Is there any nicotine in it?

No, it is sold as a nicotine-free 100ml shortfill. You can vape it as it is or add nicotine shots to reach your chosen strength within the legal UK limit. All nicotine products are for over-18s only.
