Rocky Vapor Oxbar G42K | Vape Cloud Canada
Triple Mesh Coil, 5 Firing Modes, 42,000 Puffs
The Rocky Vapor Oxbar G42K is one of the most customizable disposables available in Canada. While most disposables offer two power modes at best, the G42K gives you five firing modes, a Flavour Boost button, adjustable airflow, and adjustable nicotine intensity, all powered by a triple mesh coil that uses three heating elements instead of the standard one or two. With 20mL of 20mg/mL nicotine salt, up to 42,000 puffs, a 3D curved LED screen, and a 900mAh USB-C rechargeable battery, the G42K targets vapers who want disposable convenience with pod-system-level control.
What Makes the G42K Different
The G42K is one of the few disposables on the Canadian market using a triple mesh coil system. Three mesh heating elements work together to heat e-liquid across a much larger surface area than single or dual mesh designs. The result is denser, more even vapour, richer flavour extraction, and fewer dry hits, especially when using the higher-intensity firing modes. The triple mesh design gives the G42K a noticeable step up in vapour quality over dual-mesh competitors.
While most disposables offer one or two power settings, the G42K provides five distinct firing modes. Lower modes prioritize smooth draws and e-liquid conservation, while higher modes push the triple mesh coil harder for denser clouds and more intense flavour. The dedicated Flavour Boost button lets you temporarily spike the output for maximum flavour intensity on any individual draw. Two side buttons let you cycle through modes and control intensity on the fly. The 3D curved screen confirms your current setting.
The G42K features a nicotine control system that lets you adjust the strength of your draw across multiple levels. This gives you the ability to dial in a lighter or stronger nicotine experience from the same device, adding another layer of customization that no other disposable in this class offers. Combined with the five firing modes and adjustable airflow, the G42K provides a level of personalization normally reserved for refillable pod systems.
The G42K features a large 3D curved LED display that shows your current firing mode, nicotine level, e-liquid remaining, and battery status in real time. The curved screen wraps around the front of the device, giving it a modern look while keeping all your device information visible at a glance. The screen updates live as you adjust settings and draw.
The airflow control lets you adjust from a tight mouth-to-lung pull that mimics a cigarette draw all the way to a restricted direct-to-lung inhale for bigger clouds. The wide adjustment range means you can fine-tune the draw resistance to match your preference for any of the five firing modes, creating meaningful variation in how the device feels and performs.
With 20mL of prefilled nicotine salt at 20mg/mL, the G42K delivers up to 42,000 puffs while weighing just 95g. The compact 53 x 28 x 102mm body is lighter than most devices in the 30K+ puff category, making it genuinely pocket-friendly. The 900mAh rechargeable battery supports USB-C fast charging for minimal downtime between sessions.

How to Use the Oxbar G42K
- Unbox and inspect. Remove the G42K from packaging. Check that the mouthpiece and airflow control are clear of any protective covers.
- Charge before first use (recommended). Connect the USB Type-C cable and charge until the 3D curved screen shows a full battery.
- Select your firing mode. Use the side buttons to cycle through the five firing modes. Lower modes deliver smoother draws; higher modes produce denser vapour. The screen shows your current mode.
- Adjust the airflow. Set your preferred draw resistance from tight MTL to open RDL.
- Use Flavour Boost as needed. Press the Flavour Boost button for a temporary spike in output on any draw when you want maximum flavour intensity.
- Inhale to vape. The device is draw-activated. Inhale through the mouthpiece. The curved screen updates with battery, e-liquid, and mode information as you use it.

Frequently Asked Questions
What is the triple mesh coil?
The G42K uses three mesh heating elements instead of the standard one or two. This heats e-liquid from a significantly larger surface area, producing denser, more even vapour with richer flavour extraction. The triple mesh design is particularly effective when using the higher firing modes and the Flavour Boost button, where the extra heating surface prevents hot spots and burnt hits even at increased power output.
What are the 5 firing modes?
The G42K offers five distinct power settings that you cycle through using the side buttons. Lower modes prioritize smooth, efficient draws with maximum e-liquid conservation. Higher modes increase the coil output for denser vapour, stronger flavour, and more pronounced throat hit. The Flavour Boost button adds a temporary burst of extra power on top of whatever mode you are in. The 3D curved screen displays your current mode at all times.
How does the nicotine control work?
The G42K includes a nicotine control feature that lets you adjust the nicotine intensity across multiple levels using the side buttons. The 3D screen displays your current nicotine setting. This gives you the ability to vary the strength of your draw from the same device, making the G42K more flexible than fixed-strength disposables. Combined with the five firing modes and adjustable airflow, you can create a wide range of different vaping experiences from a single device.
How long does the G42K last?
With 20mL of e-liquid and up to 42,000 puffs, most vapers get 1 to 3 weeks from a single device depending on usage frequency and which firing modes are used most. Lower modes extend the lifespan significantly, while heavy use of the higher modes and Flavour Boost will deplete the e-liquid faster. The 3D curved screen shows your remaining e-liquid level in real time.
Can I refill the G42K?
No. The G42K is a sealed, prefilled disposable. It cannot be opened, refilled, or have its coil replaced. Once the e-liquid is depleted, dispose of the device responsibly. For refillable alternatives, browse our refillable pod systems.
How does the G42K compare to the G100K?
Both are Rocky Vapor Oxbar devices, but they target different priorities. The G100K has more capacity (30mL vs 20mL), higher puff count (100K vs 42K), and a larger 1000mAh battery. The G42K counters with a triple mesh coil (vs dual mesh), five firing modes (vs three), nicotine control (the G100K has none), a Flavour Boost button, and a lighter 95g body. Choose the G42K if you prioritize customization and vapour quality. Choose the G100K if you want maximum longevity.
Which flavour is the most popular?
Blue Razz is a consistent top seller with its candy-like sweet-tangy profile. Grape Ice is popular for its bold grape with a cool menthol finish. Peach Berry offers a classic fruit blend. Double Mint is the go-to for heavy menthol fans. For something unique, Green Storm delivers a fizzy citrus soda profile, and Cactus Fig Ice offers an unusual fruity-icy combination that stands out from typical flavour lineups.
