Uwell Viscore 8000 Prefilled Pod Kit 8,000 Puffs, 1900mAh, 4-Layer Leak-Proof
The Uwell Viscore 8000 is Uwell's first prefilled pod kit and it makes a confident entry. A 1900mAh battery that outlasts almost every competitor at this puff count. A 4-layer leak proof system built with locking cotton anti-leak airflow, a sealed feed channel, and a body seal that together stop the leaking problem that has dogged cheaper pod kits. Double concentrated 20mg nic salt e-liquid across all 10 flavours. ECO Mode for longer battery life when you need the device to stretch through the day, and Super Mode when you want the full flavour impact. And all of this for £5.49.
This is not a disposable vape. Disposable vapes are illegal to sell in the UK since June 2025. The Viscore 8000 is a rechargeable prefilled pod kit with a permanent battery and replaceable pods. The experience is just as simple as a disposable draw-activated, no buttons, no setup but the battery charges via USB-C and the pod swaps out when the e-liquid runs out. You keep the device. You replace the pod.
How the Uwell Viscore 8000 System Works
The Viscore 8000 uses the same two-part pod architecture that has become standard in the post-ban UK market. Here is how it comes together:
• 2ml prefilled pod:
Contains the 0.8 ohm mesh coil and 2ml of double-concentrated 20mg Uwell nic salt e-liquid. This is the MHRA-notified, TPD-compliant nicotine component. It clips into the top of the device and connects to the refill cartridge below.
• 10ml refill cartridge:
Transparent, so you can see the e-liquid level at all times. Pre-filled with the same flavoured 20mg nic salt e-liquid. It attaches to the 2ml pod and automatically feeds liquid up into the pod as you vape. You never need to manually fill anything.
• Total capacity:
12ml of e-liquid per kit, delivering up to 8,000 puffs depending on draw length and which power mode you are using. The 10ml cartridge makes this one of the most substantial single-kit volumes in the UK prefilled pod market.
Setup takes under 60 seconds. Remove silicone plugs from both components. Slot the pod onto the cartridge until it clicks. Insert both into the device. Start vaping. The device fires automatically on every draw no buttons required anywhere.
ECO Mode vs Super Mode What Each Actually Feels Like
-
ECO Mode:
The lower output setting. The draw is smooth and measured, flavour is clean and consistent, and the 1900mAh battery will comfortably run through a full day of regular MTL use without needing a charge. If you want to maximise battery life or prefer a lighter draw, ECO Mode is the one to use for most of your vaping. This is also the mode that gets you closest to the 8,000 puff estimate.
-
Super Mode:
Higher output, up to 16W. The vapour production increases noticeably, the flavour intensity is more immediate, and the throat hit feels fuller. For vapers who want a stronger hit, or who find ECO Mode too gentle, Super Mode is the setting that brings the Viscore 8000 closer to the feel of a higher-powered device. The trade-off is faster battery and e-liquid consumption.
-
How to switch:
Three quick taps on the USB-C charging port within 1.5 seconds toggles between ECO and Super Mode. The 3 way display updates immediately to show your active mode alongside battery percentage and e-liquid level.
The 4-Layer Leak-Proof System Why It Matters
Leaking is the most common complaint about prefilled pod kits in the UK market. Pockets, bags, and car cup holders all find the weak points in cheaper pod systems. Uwell designed the Viscore 8000's leak protection from the ground up rather than adding it as an afterthought. The four layers are:
1. Locking cotton inside the pod absorbs and holds e-liquid close to the coil, stopping it from migrating into the airflow path when the device is unused or carried horizontally.
2. Anti-leak airflow design prevents liquid from entering the air channel during the drawing motion, even when the pod is nearly empty.
3. Sealed feed channel between the 10ml cartridge and the 2ml pod creates a closed system that prevents backflow.
4. Body seal around the pod and cartridge connection point stops any surface leakage from the join between the two components.
In practice this means the Viscore 8000 handles being carried in a pocket or bag without leaving liquid residue on your belongings. It is one of the most practically leak-resistant prefilled pod kits currently available in the UK market at any price point.
What 'Double-Concentrated' Means in Practice
Uwell describes the nic salt e-liquid across all 10 Viscore 8000 flavours as double-concentrated. This means the flavouring concentration in the liquid is higher than standard nic salt formulations. The practical effect is that each puff delivers a noticeably more intense flavour hit than you would get from a standard 20mg nic salt pod at the same output level.
This is particularly noticeable on the dessert-style flavours like Milky Strawberry, where the creaminess and sweetness come through distinctly rather than fading into a generic fruity background. On the fruit-and-ice profiles like Watermelon Ice and Blue Razz Lemonade, the double-concentrate means the fruit character sits above the menthol rather than being overwhelmed by it. It is a real difference, not marketing language.
Uwell Viscore 8000 Flavour Guide All 10 Described
• Blue Razz Lemonade:
Sweet and tangy. Blue raspberry sits above a fizzy lemonade base, with a slight sourness that stops the sweetness from becoming one-dimensional. One of the most complex flavours in the range. Popular with vapers who like a sharp, refreshing hit.
• Blueberry Sour Raspberry:
Two distinct berry notes, blueberry and sour raspberry, that work well together. The sour raspberry gives it an edge that keeps the sweetness in check. Similar to bar salt fruit profiles but with the added depth that double-concentration provides.
• Cherry Ice:
Ripe red cherry with a clean menthol finish. Well-balanced the cherry is prominent without being artificial, and the ice is present without overwhelming the fruit. Good all-day flavour.
• Cherry Cola:
A genuine cola flavour with a cherry top note. The carbonated fizz element comes through on the exhale as a slight effervescence. One of the more unusual options in a prefilled pod kit range and a standout for vapers who want something different from the standard fruit or menthol options.
• Lemon and Lime:
Sharp citrus. Both lemon and lime are clearly present and the balance leans slightly more tart than sweet, which makes it one of the most refreshing options in the range. Good for vapers who find fruity flavours too sweet.
• Milky Strawberry:
Sweet, creamy strawberry. The milky element softens the fruit sharpness and creates a smooth, dessert-style profile that is genuinely distinct from standard strawberry flavours. The double-concentration makes the creaminess particularly noticeable. A standout for vapers who prefer sweet over sharp.
• Pineapple Ice:
Tropical sweet pineapple with a menthol finish. Bold and punchy. The pineapple flavour is authentic rather than candy-sweet, and the ice landing is clean without excessive cooling.
• Pink Lemonade:
Sweeter and softer than the Lemon and Lime option. A more rounded, almost berry-influenced citrus that leans into the pink lemonade aesthetic without going sugary. Good for vapers who want citrus without the sharp tartness.
• Watermelon Strawberry:
A fruit duo that pairs the lightness of watermelon with the sweeter weight of strawberry. Both flavours are distinct and neither overpowers the other. A straightforward, satisfying all-day fruit option.
• Watermelon Ice:
Juicy watermelon with a menthol finish. The watermelon is light and fresh, the ice is measured. One of the most consistently popular flavours across the prefilled pod kit category as a whole, and the Viscore 8000 version benefits from the double-concentrate formulation.

Why We Stock the Uwell Viscore 8000
Uwell has been building vaping hardware for over a decade. The Viscore 8000 is their first entry into the prefilled pod kit market and the approach they have taken is worth noting. Rather than launching a device that just meets the minimum TPD spec and calls it done, they have addressed the two biggest practical complaints about prefilled pod kits leaking and flavour fade with specific engineering solutions. The 4-layer leak system and the double-concentrated e-liquid formula both address real problems that vapers mention when they review competing products. At £5.49 it is also the best-value 8,000-puff prefilled pod kit in the UK market right now.
Frequently Asked Questions
-
Is the Uwell Viscore 8000 a disposable vape?
No. The Uwell Viscore 8000 is a rechargeable prefilled pod kit. The battery is permanent and recharges via USB-C. Only the pod and refill cartridge are replaced when the e-liquid runs out. Single-use disposable vapes are illegal to sell in the UK since 1 June 2025. The Viscore 8000 is fully compliant with UK regulations it is a reusable device, not a disposable.
-
How do I switch between ECO Mode and Super Mode?
Tap the USB-C charging port three times quickly, within 1.5 seconds. The 3-way display will update to show your new mode. You can switch at any point during use. The device does not need to be charging to switch modes.
-
How do I know when to replace my pod?
The transparent 10ml refill cartridge lets you see the e-liquid level directly. When the cartridge is empty, the pod will also be nearly depleted. At this point, you will notice a change in flavour intensity (it will drop off) or the draw may feel slightly dry. Replace both the 2ml pod and 10ml cartridge together as a complete unit. Replacement pods are available in our Uwell Viscore 8000 Replacement Pods section.
-
Does the Viscore 8000 really not leak?
The 4-layer leak-proof system is one of the device's standout features. Locking cotton, anti-leak airflow design, a sealed feed channel, and a body seal work together to prevent e-liquid migration during storage and use. No pod kit is guaranteed 100% leak-proof in every scenario, but the Viscore 8000 is among the most thoroughly engineered for leak resistance in the UK prefilled market.
-
Can I use the device while it is charging?
Yes. The Viscore 8000 supports pass-through charging, meaning you can vape while the device is connected to the USB-C charger. Draw performance remains consistent during charging.
-
How long does the 1900mAh battery last?
In ECO Mode with regular MTL use, a full charge comfortably lasts a full day. In Super Mode with heavier use, you should expect to charge once during the day. A full charge takes approximately 45 to 60 minutes via a standard USB-C charger.
-
Is the Viscore 8000 TPD compliant?
Yes. The 2ml pod capacity and 20mg/ml nicotine strength both meet the requirements of the Tobacco and Related Products Regulations 2016. The device and all pods are MHRA notified. It is fully legal to buy and use in the UK for anyone aged 18 and over.
-
Why is it called double-concentrated?
Uwell uses a higher concentration of flavouring in the Viscore 8000 nic salt formulation compared to standard prefilled pod e-liquids. This results in more intense and distinctive flavour delivery on each puff, particularly noticeable on dessert profiles like Milky Strawberry and on the fruit-ice combinations. It is the same 20mg/ml nicotine strength the difference is in the flavour concentration.
