XMax V4 Pro—pure convection with dual mode and adjustable airflow
The XMax V4 Pro is a compact dry-herb vaporizer in a slim pen design that combines modern convection technology with an unusually high level of control. Session and on-demand modes, a three-stage adjustable airflow, a replaceable 18650 battery, and a glass mouthpiece with an integrated 14 mm water-filter adapter make it one of the most versatile devices in its size class.
Pure convection and isolated airpath
With the V4 Pro, your material is vaporized using a heated airflow—without direct contact with the heating source. This enables even heat distribution and particularly flavorful vapor. In addition, the airpath is separated from the electronic components, ensuring clearly defined airflow and consistent draw performance.
Ready in about 11 seconds
The heat-up time is around 11 seconds, making the V4 Pro one of the fastest devices available. For spontaneous draws in between, that means you can switch it on and get started almost immediately.
Session or on-demand—two operating modes
The dual-mode operation accommodates two fundamentally different ways of using the device:
- Session mode: automatic temperature maintenance for 4 or 6 minutes—ideal for smooth, relaxed sessions.
- On-demand mode: heating occurs only while you hold down the button—for individual, targeted draws without unnecessary material consumption.
Three-stage airflow
The airflow can be adjusted in three stages. This lets you adapt the draw resistance to the grind size, amount of material, and your inhalation style—an important factor for extraction in a convection vaporizer because the air does the actual work.
Precise to the degree from 100 to 220 °C
Set the temperature digitally between 100 °C and 220 °C in one-degree increments. The 0.96-inch color display shows the current temperature, battery level, and operating mode, so you stay in control throughout use.
Glass mouthpiece with water-filter adapter
The included glass mouthpiece also serves as a 14 mm water-filter adapter. This means you can use it with a water filter without any additional accessories. A practical detail: the small conical rim on the mouthpiece can also be used with an 18 mm joint, covering both common sizes.
Replaceable battery and USB-C
The 18650 battery with 2550 mAh is replaceable—with a charged spare battery, you’re independent of a power outlet while on the go, and maintenance remains simple. It charges via USB-C (5 V / 1 A).
Frequently asked questions about the XMax V4 Pro
Tap a question to expand the answer.
Session or On-Demand mode—which is the difference?
In Session mode, the device automatically maintains the temperature for 4 or 6 minutes—ideal for relaxed sessions. In On-Demand mode, it heats only while you hold down the button. This is suitable for occasional individual draws and helps preserve your material because nothing vaporizes between draws.
How do I adjust the airflow?
Using the device’s three-stage airflow adjustment. A tighter setting gives you a firmer draw with more intense flavor, while a more open setting provides an easier draw. Adjust the setting to suit your grind size and filling quantity—especially with convection, this has a noticeable effect on extraction.
Do I need an extra adapter for the water filter?
No. The included glass mouthpiece also serves as a 14 mm water-filter adapter. Its conical rim can additionally be used with an 18 mm joint, covering both common sizes.
Can I replace the battery?
Yes, the V4 Pro uses a replaceable 18650 battery with 2550 mAh. For longer trips, simply bring a charged spare battery. Otherwise, it charges via USB-C at 5 V / 1 A.
Can I use the device while it is charging?
No, the device is not designed to be used while charging. However, the battery can be replaced—using a second 18650 lets you bridge the charging time without a break.
What is the dosing capsule for?
The included dosing capsule lets you pre-portion your material and insert it fully loaded. This keeps the chamber cleaner and makes changing it easier when you’re on the go—four replacement screens are also included.
Our practical tip
Use On-Demand mode when you want to conserve your material – nothing vaporizes unused between draws. Try the three airflow levels before adjusting the temperature; often, this alone provides the desired increase in density or flavor. And keep a second 18650 battery ready for longer trips.
Conclusion
The XMax V4 Pro combines convection, dual-mode operation, adjustable airflow, and a replaceable battery in a compact pen format. A versatile solution for anyone who values control, flexibility, and easy maintenance on the go – and thanks to the water filter connection, it can be used in another way at home.
