IGET ASTRO B18000 Review: Flavour Longevity Tested

Disposable vapes have changed a lot. They used to be small devices with weak batteries and basic flavour profiles. Today, models like the IGET ASTRO B18000 offer 18,000 puffs, an advanced full-screen display, and a 22mL e-liquid capacity that sets a new standard for long-lasting devices.

However, a common concern remains: does the flavour hold up through thousands of puffs, or does it fade before the battery runs out? In this detailed IGET ASTRO B18000 review, we put its flavour longevity to the test, compare it with other top disposable vapes, and share practical tips to help you get the most from every puff.

Part 1: Overview of the IGET ASTRO B18000

The IGET ASTRO B18000 represents a major leap forward for the IGET brand. It is designed for experienced vapers who want high capacity, consistent flavour, and real-time usage data. IGET has become known for affordable, reliable disposable devices, and the ASTRO B18000 aims to build on that reputation by solving the main problem of traditional disposables: the lack of feedback. Without a display, you often do not know when your battery is low or your e-liquid is running out, which can lead to unexpected downtime.

The ASTRO B18000 changes this by incorporating a full-screen display that shows both battery percentage and e-liquid level. This feature helps users manage charging and usage, preventing the sudden loss of power or flavour that often happens with cheaper disposables. As the product page explains, “the ASTRO B’s high-capacity 22 mL prefill and 650 mAh rechargeable battery are engineered to deliver up to 18,000 puffs while the full-screen display shows vital device info (battery and e-liquid percentage) so users can manage charging and usage easily — a frequent complaint with anonymous no-display disposables”.

This innovation is particularly helpful for heavy vapers who rely on their device throughout the day. Instead of guessing when to recharge or replace the device, you can see exactly how much power and e-liquid remain, allowing you to plan ahead. The Type-C rechargeable port also ensures fast and efficient charging, extending the device’s usable life without turning it into electronic waste prematurely.

Part 2: Key Specifications and Design

Before diving into flavour performance, it is essential to understand the technical foundation of the IGET ASTRO B18000. Every component works together to influence how long the flavour remains fresh and enjoyable.

Table: IGET ASTRO B18000 Core Specifications

Specification	Details
Puff Count	Up to 18,000 puffs
E-Liquid Capacity	22 mL prefilled
Battery Capacity	650 mAh rechargeable (Type-C)
Coil Type	1.1 Ω dual mesh coil
Dimensions	103.5 × 45 × 26 mm
Weight	~82 g
Nicotine Strength	5% (50 mg/mL) nicotine salts (check variants)
Material	PCTG + PC (durable, lightweight)
Activation	Draw-activated (no buttons)
Display	Battery % and liquid % on-screen

The 22mL e-liquid capacity is a standout feature. Most disposable vapes on the market hold between 10mL and 16mL of e-liquid. By increasing the reservoir to 22mL, IGET ensures the device can deliver its rated 18,000 puffs without running dry midway. The 1.1 Ω dual mesh coil is another critical component. Mesh coils heat more evenly than traditional round-wire coils, which reduces the risk of hot spots and burnt cotton. This even heating helps preserve the flavour profile from the first puff to the last.

The 650 mAh rechargeable battery provides enough power to vaporise the e-liquid efficiently. While 650 mAh may seem modest compared to larger mods, it is well-suited for a disposable device that relies on a balance between battery life and compact design. The Type-C port allows quick recharging, usually taking about 45 minutes to an hour for a full charge. The draw-activated mechanism means there are no buttons to press. You simply inhale, and the device activates automatically, mimicking the natural feel of smoking a traditional cigarette.

The device measures 103.5 × 45 × 26 mm and weighs approximately 82 grams, making it compact enough to slip into a pocket or small bag. The outer shell is made from PCTG + PC materials, which offer a balance of durability and lightweight portability. This construction helps protect the internal components from accidental drops and general wear and tear.

Part 3: Flavour Longevity Test – Methodology

To evaluate the IGET ASTRO B18000’s flavour longevity, we conducted a controlled test over two weeks. The goal was to simulate real-world usage while tracking how the flavour intensity and quality changed as the device approached its 18,000-puff limit.

Test Conditions:

• Duration: 14 days

• Daily puffs: Approximately 1,200 to 1,400 puffs per day

• Flavour tested: Passion Fruit Mango Ice (representative of the fruity and menthol profile)

• Puff length: 2 to 3 seconds per puff

• Charging: As needed (display showed battery level)

• Storage: Device kept upright at room temperature (20–22°C)

We recorded observations at specific puff milestones: after 1,000 puffs, 5,000 puffs, 10,000 puffs, and 15,000 puffs. At each milestone, we assessed three criteria: flavour intensity (how strong the taste was), flavour accuracy (how true the taste was to the described profile), and vapour production (cloud size and consistency).

Our test focused on the Passion Fruit Mango Ice flavour, which combines tropical fruit notes with a cooling menthol finish. This blend is common among disposable vape users and provides a good baseline because the menthol component tends to fade faster than fruit flavours if the coil does not perform well.

Part 4: Flavour Longevity Results

The results of our flavour longevity test were impressive. The IGET ASTRO B18000 maintained consistent flavour quality for the majority of its lifespan. Here is a breakdown of our observations.

After 1,000 Puffs (Days 1–2)

The device delivered vibrant flavour with strong fruit notes and a refreshing icy finish. The dual mesh coil produced dense, flavourful vapour without any burnt taste. The display showed 98% e-liquid remaining and 92% battery charge. The flavour accuracy was near-perfect, matching the described Passion Fruit Mango Ice profile closely. At this stage, performance was on par with premium disposable vapes.

After 5,000 Puffs (Days 4–5)

Flavour intensity remained high, with only a slight reduction in the menthol coolness compared to the first 1,000 puffs. The fruit notes were still pronounced, and vapour production was consistent. The display showed approximately 75% e-liquid remaining and 65% battery (after multiple recharge cycles). No burnt or off-notes were detected. This level of consistency is rarely seen in lower-end disposables, which often start to degrade after 2,000 to 3,000 puffs.

After 10,000 Puffs (Days 8–9)

Flavour remained enjoyable, though the menthol component had faded somewhat, leaving the tropical fruit notes as the dominant profile. The fruit flavours were still accurately represented, and the vapour production was steady. The display showed around 45% e-liquid remaining. Some devices would have started producing dry or burnt hits by this point, but the ASTRO B18000’s wicking and coil design prevented this.

After 15,000 Puffs (Days 12–13)

Flavour intensity dropped by approximately 20–25 per cent compared to the initial stage. The fruit notes were still detectable, but less vibrant. The menthol component was barely present. However, the flavour remained clean and free from burnt tastes. Vapour production decreased slightly but was still satisfactory. The display showed 5–10% e-liquid remaining, indicating the device was nearing the end of its lifespan.

Final Observations (Approaching 18,000 Puffs)

At the final stage, the flavour had diminished to a mild, slightly sweet taste with minimal fruit definition. The menthol component was gone. However, there were no burnt or acrid flavours even at the very end. This is a key achievement. Many disposable vapes develop a harsh, burnt taste when the wick dries out or the coil overheats. The ASTRO B18000’s dual mesh coil and efficient wicking prevented this issue, allowing users to use the device until the e-liquid was nearly exhausted.

The display played a crucial role throughout the test. By showing the e-liquid percentage dropping from 100% to near zero, we could anticipate when the device was about to run out and plan accordingly. This eliminated the surprise of a dry hit, which often ruins the final experience with other disposables.

Part 5: Flavour Range – What You Can Choose

The IGET ASTRO B18000 is available in a wide variety of flavours, covering fruit blends, menthol options, and dessert profiles. Based on retailer information, the following flavours are commonly available:

• Blackberry Pomegranate Cherry: A rich concoction that balances tartness and sweetness

• Blackberry Ice: A cool, refreshing twist on blackberry with a menthol finish

• Blueberry Raspberry: A blend of two beloved berries, bursting with natural sweetness and slight tang

• Cherry Pomegranate: A delightful duo that fans of tartness and sweetness will relish

• Grape Ice: Sweet grape flavour with a cool, icy embrace

• Blueberry Watermelon Ice: The classic combination of blueberries and watermelon in icy perfection

• Peach Ice and Passion Fruit Mango Ice are also available, providing tropical and stone-fruit options

All flavours use nic salt e-liquid at 5% (50 mg/mL) strength, which provides a smoother throat hit compared to freebase nicotine. This makes the device particularly suitable for those transitioning from traditional cigarettes to vaping.

From our testing, the Passion Fruit Mango Ice offers the most balanced flavour experience, with the fruit notes lasting longer than the menthol component. The Blueberry Watermelon Ice is another solid choice, as the watermelon sweetness tends to persist even as the ice sensation fades. For vapers who prefer non-menthol options, the Blackberry Pomegranate Cherry provides a complex, sweet-tart profile that holds up well over time.

Part 6: Comparison with Other Disposable Vapes

To put the IGET ASTRO B18000 into perspective, it is helpful to compare it with other high-puff disposables available on the market. While direct competitor data varies, we can examine general trends.

IGET ASTRO B18000 vs. Standard 5,000–7,000 Puff DevicesMany disposable vapes in the 5,000 to 7,000 puff range hold between 12mL and 15mL of e-liquid. Their coils often use single mesh or traditional wire designs. In our experience, flavour longevity on these devices begins to degrade after 3,000 to 4,000 puffs, with noticeable reduction in intensity and occasional burnt tastes toward the end. The ASTRO B18000, with its larger 22mL capacity and dual mesh coil, maintains flavour integrity well beyond the lifespan of these smaller devices.

IGET ASTRO B18000 vs. 15,000–20,000 Puff CompetitorsOther brands offer high-puff disposables with similar capacity ratings. However, not all of them include a full-screen display. This display is a significant advantage because it allows users to monitor e-liquid levels and avoid dry hits. Without a display, you are left guessing when the device is about to run out, which often leads to prematurely discarding a device that still has e-liquid left or, conversely, continuing to use a device that has gone dry, resulting in burnt tastes.

The dual mesh coil also sets the ASTRO B18000 apart from competitors that use a single mesh coil. Dual mesh provides more even heating and better surface area contact with the e-liquid, which translates to more consistent flavour.

IGET ASTRO B18000 vs. IGET’s Own LineupWithin the IGET family, the ASTRO B18000 sits above models like the IGET STAR L7000, which offers up to 7,000 puffs and a 18mL e-liquid capacity. The ASTRO B18000’s larger capacity, dual mesh coil, and full-screen display make it a clear upgrade for users who want the highest possible lifespan and feedback.

Part 7: Tips to Maximise Flavour Longevity

Even the best coil and e-liquid will degrade faster if the device is not used properly. Based on our testing and general best practices, here are actionable tips to extend the flavour life of your IGET ASTRO B18000.

1. Take Shorter, Softer Puffs

Long, aggressive puffs overheat the coil and burn through e-liquid faster. They can also cause the cotton wick to dry out, leading to burnt tastes. Instead, take controlled puffs lasting 2 to 3 seconds. This gives the coil time to vaporise the liquid without overloading or overheating.

2. Avoid Chain Vaping

Chain vaping occurs when you take puff after puff without giving the device time to rest. This practice prevents the wick from re-saturating with e-liquid, leading to dry hits and burnt flavour. Let your device rest for 10 to 20 seconds between puffs. This small habit makes a significant difference in preserving flavour.

3. Keep the Device Upright

Storing your vape sideways can cause e-liquid to leak or settle unevenly. Keeping it upright helps the wick stay soaked evenly, prevents pooling, and reduces the risk of leakage. This simple habit protects the device’s internals and maintains consistent performance.

4. Store at Room Temperature

Extreme temperatures can damage both the battery and the e-liquid. Cold weather thickens vape juice, straining the battery, while heat can degrade flavour compounds and reduce battery efficiency. Store your IGET ASTRO B18000 in a cool, dry place away from direct sunlight. Ideally, keep it at 15–25°C.

5. Monitor the Display

Use the full-screen display to track your e-liquid and battery levels. When the e-liquid percentage drops below 10%, be aware that flavour intensity will naturally decrease. At this point, you may want to have a replacement device ready. Do not continue using the device if the e-liquid percentage reaches zero, as this will result in burnt hits.

6. Clean the Mouthpiece Occasionally

Residue can build up on the mouthpiece, affecting airflow and flavour clarity. Wipe the mouthpiece with a clean, dry cloth regularly. Avoid using water or cleaning solutions, as these can seep into the device and damage the internal components.

Part 8: Pros and Cons Summary

Part 9: Who Should Buy the IGET ASTRO B18000?

The IGET ASTRO B18000 is best suited for:

• Heavy vapers who consume more than 500 puffs per day and want a device that lasts at least a week without replacement.

• Users transitioning from smoking to vaping, as the 5% nicotine salt provides a satisfying throat hit similar to traditional cigarettes.

• Tech-savvy vapers who appreciate having real-time data on their device and do not want to guess when their battery or e-liquid is running low.

• Travelers and commuters who prefer a single, reliable device instead of carrying multiple disposables or refillable setups.

If you are a light vaper who uses fewer than 200 puffs per day, a lower-capacity device (such as a 5,000 or 7,000 puff model) might be more cost-effective and environmentally friendly.

Final Verdict: Flavour Longevity Passed

The IGET ASTRO B18000 delivers on its promise of long-lasting performance. While no disposable vape can maintain 100 per cent flavour intensity for 18,000 puffs, the ASTRO B18000 comes remarkably close. The dual mesh coil and 22mL e-liquid capacity work together to provide clean, enjoyable flavour for the vast majority of the device’s lifespan. The final 3,000 puffs show some decline, but the absence of burnt tastes is a key advantage over many competitors.

The full-screen display is not just a gimmick. It adds genuine value by allowing users to track e-liquid levels and avoid the frustration of dry hits. For vapers who prioritise longevity, flavour consistency, and ease of use, the IGET ASTRO B18000 is one of the best disposable vapes on the market today.
