UOR AL BANG 300K review：Most product listings begin with the headline figure: up to 300,000 puffs. However, that number alone does not explain how the UOR AL BANG 300K feels in everyday use, how different its two airflow modes are or how often the battery needs charging.
For this UOR AL BANG 300K review, we used one unit regularly for approximately five to six days. During the test, we switched between the tighter mouth-to-lung setting and the more open direct-to-lung setting, while also checking the screen, vapor output, Type-C charging system and general performance.
Our main finding was straightforward: the tighter setting produced a controlled draw and moderate vapor, while opening the airflow created a noticeable increase in both airflow and cloud volume. Under our mixed-use conditions, the device did not require charging until roughly the fifth or sixth day.
This was a real-use test rather than a laboratory battery rundown. Individual results will vary depending on puff length, frequency, airflow position and the amount of DTL use.
Quick Verdict
The UOR AL BANG 300K works best for adult users who want a very high-capacity device without being restricted to one draw style.
Its MTL setting offers a tighter and more controlled inhale. Opening the airflow changes the experience considerably, producing a looser draw and much larger vapor output. The difference is clear enough to make the dual-mode design useful rather than merely decorative.
The battery was another positive point. During our test, the unit operated for around five to six days before it needed its first recharge. Frequent DTL use will consume power more quickly, so heavier users should expect a shorter interval between charges.
The screen is easy to check, the Type-C port makes recharging convenient and the manufacturer-listed quad-mesh system delivered stable output throughout our test.

How We Tested the UOR AL BANG 300K
We tested one UOR AL BANG 300K as a regular-use device for approximately five to six days before its first recharge.
Instead of using only one airflow position, we alternated between:
- A tighter setting for mouth-to-lung draws
- A more open setting for direct-to-lung draws
- Shorter and longer puffs during normal use
- Regular checks of the screen and battery indicator
We did not run an artificial continuous-puff stress test, record an exact number of puffs per day or dismantle the device to inspect its internal coil structure.
Therefore, the results below describe our experience with one test unit. They should not be treated as a guaranteed battery duration or exact puff count for every user.
MTL Test: Draw Resistance and Vapor Output
With the airflow set toward its tighter position, the UOR AL BANG 300K produced a controlled mouth-to-lung draw.
The resistance was noticeable without feeling completely closed. It allowed us to take slower, more measured puffs without pulling too much air through the device.
Vapor output in this setting was visible but relatively manageable. It produced less vapor than the open-airflow mode and felt better suited to users who prefer a calmer draw instead of the largest possible cloud.
The MTL setting may be the better choice for:
- Users who prefer a tighter inhale
- Those who want more controlled vapor output
- People who take shorter or less frequent puffs
- Users who want to reduce battery consumption compared with frequent DTL use
It is worth noting that the draw does not feel as tight as some small traditional MTL pod systems. It sits closer to a moderately restricted disposable-vape draw.
DTL Test: What Changed When We Opened the Airflow?
Opening the airflow produced an immediate and obvious change.
The draw became looser, more air entered the device and the amount of vapor increased noticeably. Clouds appeared denser and expanded faster than they did in the tighter MTL setting.
For experienced users, the fully open setting may feel closer to restricted direct-to-lung vaping than to an entirely unrestricted sub-ohm tank. Nevertheless, the difference between the two settings is substantial enough to provide two distinct experiences from the same device.
The DTL setting may suit adult users who prefer:
- A more open and airy draw
- Higher vapor output
- Longer inhalations
- A fuller cloud from each puff
The trade-off is increased power and e-liquid consumption. If the device is used mainly with the airflow fully open, it is reasonable to expect more frequent charging than we experienced during our mixed-use test.
MTL vs DTL: Side-by-Side Results
| Test area | Tighter MTL setting | Open DTL setting |
|---|---|---|
| Draw resistance | Noticeably tighter and controlled | Looser and more open |
| Vapor output | Moderate and manageable | Significantly larger |
| Puff style | Shorter, slower draws | Longer, airier draws |
| Battery demand | Generally lower | Generally higher |
| Idéal pour | Controlled everyday use | Users prioritizing cloud volume |
The airflow control is one of the strongest features of the UOR AL BANG 300K because it changes more than the feeling of the inhale. It also affects cloud volume and likely influences how quickly the battery and e-liquid are consumed.
Battery Test: Five to Six Days Before Charging
During our mixed-use test, the UOR AL BANG 300K operated for approximately five to six days before it needed to be recharged.
This was one of the most practical advantages we observed. We did not have to connect the device to a charger every day, even though we tested both airflow modes during that period.
However, this result needs context.
Battery duration may be shorter if you:
- Vape more frequently throughout the day
- Take longer puffs
- Mainly use the open DTL setting
- Use the device continuously for extended periods
- Recharge before the battery becomes low
Likewise, lighter MTL use may allow a longer interval between charges.
Because we did not record an exact daily puff count, our five-to-six-day result should be treated as a real-use reference rather than a universal battery-life promise.
Type-C Charging Experience
The Type-C charging port makes the rechargeable format much more practical. It allows the device to continue using its remaining e-liquid instead of becoming unusable when the battery level drops.
The port was straightforward to access, and the screen made it easier to decide when charging was actually necessary.
We did not time a complete zero-to-100% charging cycle, so we are not claiming a specific full-charge time. Charging speed may also vary depending on the cable, power source and remaining battery level.
Always place the device on a stable, heat-resistant surface while charging and avoid leaving it connected unattended.
Is the Screen Actually Useful?
The screen is more than a visual design feature.
During the test, it helped us monitor the device status and decide when to recharge. This removes much of the guesswork associated with high-capacity devices that provide no useful battery information.
The display is particularly valuable on a device intended for long-term use. Without it, users would have to rely on weaker output or a flashing light to determine when the battery was nearly empty.
Like most compact device indicators, the readings should be treated as practical estimates rather than laboratory measurements. Even so, the screen provides useful information at a glance and improves the overall daily experience.
Quad-Mesh Performance
According to the manufacturer’s specifications, the UOR AL BANG 300K uses a quad-mesh heating system.
Our test focused on the results produced by the device rather than a destructive internal teardown. In practical use, vapor output remained stable, and we did not notice a significant delay when taking a puff or switching between airflow settings.
The tighter setting delivered controlled vapor, while the open setting allowed the heating system to produce a much fuller cloud. That consistent response is more useful in daily use than the coil count alone.

Is the UOR AL BANG 300K Worth Choosing?
The strongest reason to consider the UOR AL BANG 300K is not simply the headline puff number. Its main advantage is the combination of adjustable airflow, genuinely different MTL and DTL behavior, a useful screen and a rechargeable battery that performed well during our test.
The MTL setting offered a controlled draw with moderate vapor. Opening the airflow produced a clear increase in cloud volume and created a more direct-lung-oriented experience.
Our test unit lasted approximately five to six days before its first recharge, but heavier use, longer puffs and frequent DTL vaping will reduce that interval.
For adult users who want one high-capacity device that can move between controlled MTL use and higher-output restricted DTL use, the UOR AL BANG 300K is a strong option.
