UWIN RandM Crystal Twins 40K Dual Flavor is listed at 40,000 puffs with 16 flavour options and nicotine at 2% (20mg/ml), 5% (50mg/ml).

What the UWIN RandM Crystal Twins 40K Dual Flavor offers

• Rated 40,000 puffs — That is the manufacturer’s estimate from liquid volume; treat it as a scale marker rather than a counter.
• 16 flavours on one model — Each of the 16 entries is a separate variant on this listing, selectable at order time.
• LED display — The screen — a LED display — keeps the device’s state on its face rather than in its draw.
• 850 mAh rechargeable cell — A 850 mAh rechargeable cell, topped up over Type-C — the charging cycle repeats across the rating.
• 40K-79K Puffs capacity bracket — It shares the 40K-79K Puffs bracket with 53 other listings, which is where like-for-like comparison starts.
• Nicotine at 2% (20mg/ml), 5% (50mg/ml) — Buyers choose strength alongside flavour; the range here is 2% (20mg/ml), 5% (50mg/ml).

What is inside a 40,000-puff device

Figures below come from the manufacturer’s specification for this exact model.

The 850 mAh cell against a 40,000-puff rating means charging is scheduled use, not an emergency.

Background: The two listings — percent and mg/ml — are arithmetic mirrors of each other. EU retail tops out at 20 mg/ml, and the figures here are stated against that ceiling.

Background: The stock position also steadies availability: EU-held inventory reorders on short cycles rather than long ones.

The flavour list: 16 options

The names that follow are live options; a missing name is a name out of stock, not a name omitted.

Reading the list by family: 8 iced entries, 3 drink-led entries, a single berry entry, a single tropical entry, a single melon entry.

Flavour by flavour

A note on the names: they are the manufacturer’s, reproduced as given — sweet-sounding entries included, because that is the naming convention in this category.

• Blueberry On Ice & Summer Peach Ice — This is a 2-part combination covering Blueberry On Ice, Summer Peach Ice, the parts sit in their own reservoirs rather than in one shared tank.
• Kiwi Passion Fruit Guava & Blueberry Raspberry — A multi-part profile built from Kiwi Passion Fruit Guava, Blueberry Raspberry — each part is a separate supply rather than a blend, so the draw moves between them.
• Strawberry Kiwi & Grape Ice — This is a 2-part combination covering Strawberry Kiwi, Grape Ice — and the separation is the point of the combination rather than a side effect.
• Kiwi Passion Fruit Guava & Two Apple — This is a 2-part combination covering Kiwi Passion Fruit Guava, Two Apple; each part is a separate supply rather than a blend, so the draw moves between them.
• Strawberry Watermelon & Lemon Lime — A multi-part profile built from Strawberry Watermelon, Lemon Lime; each named part has its own feed to the coil, so the flavours do not merge in use.
• Blueberry Raspberry & Cherry Ice — Blueberry Raspberry, Cherry Ice are the parts named here — each named part has its own feed to the coil, so the flavours do not merge in use.
• Strawberry Raspberry Cherry & Mr Blue — The name states the split directly: Strawberry Raspberry Cherry, Mr Blue, the parts are stored separately, so the last one drawn does not taste of the first.
• Peach Mango Pineapple & Red Bull — This entry combines Peach Mango Pineapple, Red Bull behind a single name; a single tank would blend them, so the switching body is what keeps them apart.
• Watermelon Ice & Mixed Berries — Watermelon Ice, Mixed Berries is the combination written on the label — each part is a separate supply rather than a blend, so the draw moves between them.
• Strawberry Banana & Love 66 (Passion Fruit Melon Ice) — Strawberry Banana, Love 66 (Passion Fruit Melon Ice) are the parts named here; and the separation is the point of the combination rather than a side effect.
• Dragon Fruit Banana Cherry & Pink Lemonade — Combination entry covering Dragon Fruit Banana Cherry, Pink Lemonade; a single tank would blend them, so the switching body is what keeps them apart.
• Peach Mango & Cherry Cola — The name states the split directly: Peach Mango, Cherry Cola; the parts sit in their own reservoirs rather than in one shared tank.
• Strawberry Ice & Mango On Ice — Strawberry Ice, Mango On Ice is the combination written on the label, the parts are stored separately, so the last one drawn does not taste of the first.
• Blue Razz Ice & Dragon Fruit Ice — The label names 2 parts — Blue Razz Ice, Dragon Fruit Ice; switching moves the draw from one supply to another, which is what keeps the parts distinct.
• Strawberry Red Bull & Cherry Ice — Strawberry Red Bull, Cherry Ice is the combination written on the label, and the separation is the point of the combination rather than a side effect.
• Random Flavors (Fast Delivery) — A stock-pick line rather than a taste. Choosing it means the next units off the shelf, whatever they are — the fastest route out of the warehouse, and the least predictable.
