We took a close look at the hardware of the UZY Crystal 4 In 1 100000. It is a high-capacity disposable vape built for variety. Instead of one large e-liquid tank, it holds four separate e-liquid pods inside. You rotate the top to switch to a different flavor. This design solves the common problem of flavor fatigue in high-puff devices.
Below are the exact technical specifications:
- Puff Count: Up to 100,000 puffs in total.
- E-Liquid Capacity: 56 mL total (divided into four independent 14 mL e-liquid tanks).
- Battery: 650 mAh rechargeable battery.
- Charging: Type-C port (5V/1A).
- Coil Type: 1.0-ohm Quad Mesh Coil.
- Nicotine Strength: Available in 0%, 2%, 3%, and 5% nicotine salt options.
- Display: Smart LED screen (shows current battery life and e-liquid levels).
- Design: Clear polycarbonate body with internal astronaut visual elements.
- Weight: Approximately 140 grams.

Design and Build Quality: Clear, Durable, and Comfortable
When we first held the UZY Crystal, the transparent polycarbonate shell stood out immediately. This material makes the device highly drop-resistant while showing off the internal structure. The small astronaut figure inside adds a unique modern touch, especially when the LED screen lights up.
At 140 grams, it is slightly heavier than a standard disposable vape, but it feels incredibly solid. I accidentally dropped our test unit from my desk, and the clear polycarbonate shell did not crack or scratch. For a vape holding 56 mL of e-liquid, the compact size is impressive.
Battery and Lifespan: Built for Heavy Users
The 56 mL e-liquid capacity delivers up to 100,000 total puffs. To support this volume, the UZY features a 650 mAh rechargeable battery. In our testing, a full charge lasts through heavy daily use. When the battery runs low, the Type-C port charges it back up quickly. You do not have to worry about the device dying in the middle of the day.
Quad Mesh Coils: Consistent Flavor Delivery
Each of the four liquid tanks connects to its own 1.0-ohm mesh coil. Because of this separated setup, every flavor maintains its peak performance. The mesh coils heat evenly and create thick vapor. We noticed excellent flavor accuracy and a very smooth throat hit from the first vaping to the last.
Smart LED Display: No More Burnt Hits
The biggest risk with large-capacity disposable vapes is getting a sudden burnt taste when the liquid secretly runs out. The UZY Crystal fixes this with a bright, intuitive screen. It shows the exact percentages for your battery life and remaining e-liquid. You always know when to charge the device and when a e-liquid tank is empty.
The biggest advantage of the UZY Crystal is stopping flavor fatigue. When a flavor starts feeling dull, you do not have to wait until the e-liquid tank is empty. A quick click to the next e-liquid tank refreshes your taste buds. Our testing confirmed that the flavor isolation is perfect—there is absolutely no mixing of tastes between the channels.
Who Benefits Most from This Device?
- Flavor Explorers: If you hate committing to a single taste, you now get four premium options in one device.
- Minimalist Vapers: Stop carrying two or three different devices in your pocket. One vape handles everything.
- Gadget Fans: The satisfying mechanical “click” when rotating e-liquid tanks adds a fun, premium feel to every use.
Perfect for Your Daily Routine
- Travel and Road Trips: A single device covers a long trip. You can switch flavors to keep the drive interesting without worrying about packing extra gear.
- All-Day Rotation: Start your morning with a bright Lemon Lime, switch to a sweet Peach Mango in the afternoon, and end the night with a cool Black Ice.
- Social Settings: The glowing screen and unique twisting action make it a great conversation starter at parties or bars. It is also easy to share different flavors with friends.
1. Unboxing and Priming
- Remove all seals: Pull the silicone plug out of the mouthpiece and peel off the protective sticker at the bottom before use. Airflow is blocked until these are removed.
- Wait 2 minutes: After removing the seals, let the device sit upright for a few minutes. This allows the cotton to absorb the e-liquid properly, preventing a harsh, burnt first hit.
2. Switching Flavors Correctly
- Listen for the click: Twist the device until you hear and feel a solid “click.” This means the new flavor channel is locked in place.
- Do not vape halfway: Never draw when the mechanism is stuck between two flavors. It blocks airflow and can cause leaks or dry hits.
3. Reading the Smart Screen
- Charge at 20%: Plug the device in when the battery drops to 20%. Low power reduces vapor production and weakens the flavor.
- Watch the liquid icon: If the e-liquid indicator flashes or shows empty, stop using that specific flavor e-liquid tank to avoid burning the coil.
4. Charging Safely
- Use a standard charger: Always use a basic 5V/1A charger (like a PC USB port). We actually ruined one of our UZY test units by plugging it into a 65W laptop fast charger. It overheated the battery and permanently burnt the flavor. Do not make our mistake.
- Unplug when full: It takes about 45 to 60 minutes for a full charge. Do not leave it plugged in overnight.
5. Daily Maintenance
- Pace your puffs: Leave 3 to 5 seconds between puffs so the cotton can soak up more liquid.
- Store upright: Keep the device standing straight up on a desk when not in use.
- Avoid extreme heat: Never leave this device in a hot car. High temperatures increase pressure inside the e-liquid tanks and will cause massive leaks.
With 10 different combo options available, picking the right one can be tricky. We tested the flavor profiles to help you choose the best matrix for your daily use.
For the Sweet Tooth (Candy & High Sweetness)
If you love sugary, candy-like vapes, choose these:
- Combo 7: Features Gummy Bear for a rich, recognizable candy sweetness, blended with juicy fruit notes.
- Combo 6: Watermelon Bubblegum gives a classic sweet taste, while the Lemon Lime e-liquid tank cuts through the sugar to keep it balanced.
For Max Ice & Intense Throat Hit
If you hate sweet vapes and want a sharp, freezing sensation:
- Combo 8: The coldest option. It features Black Ice (heavy mint and blackberry) and Mr Blue for an extreme, brain-freezing throat hit.
- Combo 9: The Fizzy Cherry Ice adds a unique soda-like tingling sensation on your tongue, making it very refreshing.
For Tropical & Exotic Tastes
If you prefer complex, realistic fruit blends over standard flavors:
- Combo 1: Kiwi Passion Fruit Guava offers a sharp, tangy tropical mix with an excellent, realistic fruit aroma.
- Combo 3: Features Love 66, a famous shisha profile mixing melon, passion fruit, and a hint of floral mint for an exotic vibe.
For Tart & Tangy Berries
If you want a slight sourness to stimulate your taste buds:
- Combo 4: Cranberry Grape brings a dry, tart fruit-skin flavor. It is refreshing and never feels too sugary, making it perfect for all-day use.
A Warning on Combo 2: Read Before You Buy
Our team bought and vaped all 10 flavor combinations. We suggest avoiding Combo 2. The “Two Apple” e-liquid tank caught me off guard with its harsh medicinal licorice taste. The problem is the Two Apple flavor.
Many beginners expect a fresh, crisp green or red apple taste. However, in the global vape industry, Two Apple is a traditional Middle Eastern shisha recipe. Its main flavor is not fruit—it is heavy black licorice and anise.
Switching from a sweet Strawberry Banana e-liquid tank straight into a strong, medicinal licorice flavor is a very harsh jump. Unless you specifically love black licorice or traditional shisha, we recommend avoiding any combo that includes Two Apple.

The Core Battle: Variety vs. Loyalty
- UZY is built for variety. It assumes you will get bored of a single taste over 100,000 puffs. The 4-in-1 system is the ultimate fix for flavor fatigue.
- Fizzy is built for loyalty. It uses a massive single e-liquid tank. This is designed for traditional vapers who strictly love one specific flavor (like pure Watermelon Ice) and want it to remain consistent for weeks.
Hardware Focus: Transparency vs. Power
- UZY wins on transparency. By clearly stating the 56 mL capacity, you know what you are paying for.
- Fizzy wins on raw power. While its exact liquid volume is hidden, its Dual Mesh Coil provides a stronger, thicker throat hit compared to UZY’s standard mesh.
Which One Should You Buy?
Buy the UZY Crystal 4-in-1 if:
- You get bored of vaping the same flavor after a few days.
- You want the security of knowing you have 56 mL of e-liquid.
- You enjoy the mechanical “click” and playful transparent design.
Buy the Fizzy X-Space 100K if:
- You are deeply loyal to one single flavor and never want to switch.
- You prefer the aggressive throat hit and thick clouds of a Dual Mesh coil.
- You love high-tech, sports-car style holographic screens.
You are buying 56 mL of e-liquid that will last for weeks. Picking the wrong nicotine level will ruin the experience. Choose your strength based on your current vaping habits:
5% (50mg/mL) – For Heavy Users: Delivers a fast, strong throat hit. Warning: Because the UZY mesh coils heat up so powerfully, this high strength can quickly make you feel dizzy. Do not chain-vape the 5% option.
3% (30mg/mL) – The Best Daily Choice: The perfect middle ground. It provides a satisfying throat hit but does not hide the fruit flavors. We recommend this level for most standard vapers.
2% (20mg/mL) – For Reducing Nicotine: A very soft throat hit. Lowering the nicotine allows the sweetness and ice notes of the e-liquid to stand out. Great for light, social vaping.
0% (0mg/mL) – Zero Nicotine: Pure flavor and vapor. Perfect if you have quit nicotine but still miss the hand-to-mouth habit.
Pro-Tip for the 4-in-1 System
When you first get this device, you will naturally want to twist the e-liquid tanks and chain-vape to taste all four flavors. If you buy your usual high nicotine strength, you will consume too much nicotine during this testing phase. We suggest buying one step lower than your usual strength (for example, buy 3% if you normally vape 5%) for the most comfortable experience.

The End of Flavor Fatigue
We’ve all been there—vaping the same e-liquid all day eventually dulls your taste buds. UZY fixes this "vaper's fatigue" by putting multiple flavors into a single device. Whether you choose the reliable 3-in-1, the diverse 6-in-1, or the massive 10-in-1 setup, you can stop carrying multiple vapes in your pocket. Switch from a cool morning fruit blend to a rich evening dessert flavor by simply rotating or repositioning the mouthpiece. Your taste stays sharp, and every puff hits like the first.
Maximum Puffs, Maximum Value
Let’s talk about endurance. UZY pushes the limits of what a disposable vape can actually do. The official UZY lineup we carry ranges from a highly portable 15,000 puffs right up to a staggering 500,000 puff capacity. This isn’t just about big numbers—it’s about cost-per-puff efficiency. A larger e-liquid capacity and optimized battery life mean fewer trips to the store and less money spent. You get maximum mileage out of one device, making it a seriously smart investment for daily vapers.
