The JNR Mega Box Pro 50K Disposable Vape is a high-capacity disposable vape designed for adult nicotine users who prioritize extended use, convenient charging, and easy-to-read device information. With a claimed up to 50,000 puffs, 32ml of pre-filled e-liquid, an 850mAh rechargeable battery, and a 1.2Ω dual-mesh coil, the Mega Box Pro sits firmly in the large-capacity disposable category.
It also adds features that are becoming increasingly common in large-format disposables, including a smart screen for monitoring battery and e-liquid levels and a USB Type-C charging port.

The manufacturer’s specifications list a 32ml e-liquid capacity, 1.2Ω dual-mesh coil, smart screen, 2% nicotine strength, and approximately 50,000 puffs.
Up to 50,000 Puffs
The headline feature is obviously the 50K puff rating.
JNR says the Mega Box Pro can provide up to 50,000 puffs from its 32ml e-liquid supply. This is intended to give the device a much longer service life than conventional small disposable vapes.
However, the 50,000-puff figure should be regarded as an advertised maximum, rather than a guaranteed number of draws. Actual usage depends on factors such as puff duration, frequency, airflow and individual vaping habits.
For buyers primarily interested in reducing how often they need to replace their device, the large e-liquid reservoir is one of the Mega Box Pro’s biggest advantages.
32ml Pre-Filled E-Liquid Capacity
The Mega Box Pro comes pre-filled with 32ml of e-liquid.
That is a substantial capacity for a disposable-style device and is the foundation of its long-use design. Users do not need to refill the device or replace a conventional coil.
The combination of a large reservoir and rechargeable battery means the device is designed to continue operating over an extended period rather than being discarded after the battery’s first charge.
850mAh Rechargeable Battery
A large e-liquid reservoir would have limited usefulness without a rechargeable battery. The JNR Mega Box Pro therefore incorporates an 850mAh battery with USB Type-C charging.
The rechargeable design allows users to replenish the battery during the device’s lifespan instead of throwing the device away once its initial charge is depleted.
USB-C is also convenient because it is now widely used across smartphones, tablets, computers and other electronics.
Smart Screen
Another major feature is the integrated smart screen.
According to JNR, the screen provides real-time information about the device’s battery and e-liquid levels.
This is particularly useful for a high-capacity disposable because there is a lot more e-liquid to monitor. Instead of relying entirely on changes in vapor production or flavor, users can check the display to get an indication of the remaining battery and liquid.
1.2Ω Dual Mesh Coil
The Mega Box Pro uses a 1.2Ω dual-mesh coil. JNR describes the coil as being designed for consistent, flavor-focused performance and a mouth-to-lung draw.
The dual-mesh configuration is designed to heat the e-liquid evenly while producing a consistent draw. It also fits the overall positioning of the device: long-lasting performance combined with a focus on flavor.
Embossed Metal-Style Exterior
The design is another area where the Mega Box Pro attempts to distinguish itself.
JNR describes the exterior as featuring an embossed metal texture, giving the device a more substantial and premium appearance than many basic disposable vapes.
The combination of the textured exterior, large body and integrated display gives it more of a compact box-style appearance.
20+ Flavor Options
Flavor variety is another strong point. JNR lists 20 flavor options, covering fruit, ice, candy and beverage-inspired profiles.
Some listed options include:
- Blue Razz Cherry
- Cherry Cola
- Mixed Berry
- Fresh Strawberry
- Watermelon Ice
- Double Apple
- Kiwi Watermelon Ice
- Strawberry Kiwi
- Cola Ice
- Passion Fruit Kiwi
- Summer Peaches
- Love 66
- Hawaii
- Sour Cherry Ice
- Blue Razz Ice
- White Peach Razz
Availability can vary depending on the market and retailer.
2% Nicotine Strength
The JNR Mega Box Pro is listed with a 2% nicotine concentration, or 20mg, depending on the market version.
Nicotine is addictive, and this type of product is intended only for adults who are legally permitted to purchase nicotine products. Local regulations can also limit nicotine concentration, e-liquid capacity, packaging and availability.
What Makes the JNR Mega Box Pro 50K Different?
The Mega Box Pro combines several features that are usually spread across different high-capacity devices:
Large capacity: 32ml of pre-filled e-liquid provides the foundation for the extended-use design.
Rechargeability: The 850mAh battery can be recharged through USB-C.
Smart monitoring: The display provides battery and e-liquid information.
Dual-mesh technology: The 1.2Ω dual-mesh coil is designed around consistent flavor delivery.
Premium appearance: The embossed metal-texture exterior gives the device a more distinctive look.
Together, these features make the Mega Box Pro more technologically equipped than a basic disposable vape.

Final Verdict

Rather than focusing on an ultra-small form factor, JNR has designed the Mega Box Pro around long-term use and device monitoring. The smart screen is particularly useful because it lets users see battery and e-liquid information, while USB-C charging complements the large e-liquid capacity.
