X-MAX V4 Pro heats dry herb primarily through convection (hot air) and secondarily through conduction (heated chamber walls), offers three-stage airflow control, a choice between session and on-demand modes, delivers exceptional vapor quality, and is powered by a replaceable 18650 battery. The glass mouthpiece with a built-in water pipe adapter and a color OLED display complete the picture of one of the best portable dry herb vaporizers in its price range.
X-MAX V4 Pro Vaporizer – Successor to a Legend
The X-MAX V4 Pro vaporizer is the direct successor to the iconic V3 Pro model, which enjoyed enormous popularity among vaping enthusiasts worldwide for years. Manufacturer XVAPE listened to user feedback and created a device that retains all the strengths of its predecessor – predominantly convective heating, a replaceable 18650 battery, and a compact pen form – while introducing a range of significant improvements. Three-stage airflow control, a glass mouthpiece as standard, a color OLED display, and a thoughtfully designed battery compartment make the V4 Pro not a cosmetic refresh, but a full-fledged new generation.
X-MAX V4 Pro Vaporizer – Pure Convection, Pure Flavor
At the heart of the X-MAX V4 Pro is a hybrid heating system with an emphasis on convection. Hot air flows through the herb, heating it evenly from all sides. The herbs are also gently warmed by the hot chamber walls. The result is a noticeably cleaner, more aromatic vapor flavor and better, more uniform extraction of active compounds from the herbs.
Importantly, the vapor path in the V4 Pro is completely isolated from the device’s internal electronics. Vapor only comes into contact with the heating chamber and glass mouthpiece, ensuring safe operation and eliminating any unwanted aftertastes. Lower temperatures in the 150-170°C range bring out subtle aromatic notes and smoother vapor, while higher settings in the 190-220°C range produce thick, intense clouds. Heat-up is lightning fast – just 11 seconds to reach the maximum temperature of 220°C! The device signals readiness with a vibration, so you can start your session immediately.
X-MAX V4 Pro Vaporizer – Three-Stage Airflow Control
This is definitely the biggest new feature compared to its predecessor and a function that sets the V4 Pro apart from the competition in this price segment. The three-stage airflow switch is built directly into the body – with no additional parts to attach or lose. Simply slide the switch on the side of the device to instantly change the draw character:
At the widest setting, air flows freely, delivering a light, cool draw with a large vapor volume. The ideal setting for those who prefer gentle, aromatic experiences and lower temperatures.
The middle setting is the sweet spot – a universal everyday option providing a good balance between vapor intensity and comfortable temperature.
At maximum restriction, the draw is noticeably tighter, and the vapor becomes warmer and denser. This setting is for users who enjoy strong, intense draws, especially at higher temperatures and when using a water filter.
In a hybrid vaporizer focused on convection, airflow control is crucial – hot air is what heats the herbs, so the speed and force of the draw directly affect the amount of flavor and vapor density. With three airflow settings, you can tailor the session character not only to the selected temperature, but also to your own preferences and type of herb.
X-MAX V4 Pro Vaporizer – Session and On-Demand Modes in One Device
Like its predecessor, the X-MAX V4 Pro offers two operating modes – and this is still a rarity in vaporizers at this price point.
In session mode, the vaporizer heats the herbs and maintains the set heater temperature for 4 or 6 minutes (depending on the selected timer). This is the ideal solution for a calm, unhurried inhalation – for example, while watching a movie, relaxing in the garden, or in company. No buttons to press or hold; the device operates automatically.
In on-demand mode, heating occurs only while the button is held down, with a limit of 30 seconds per press. This mode works perfectly when you need one or two quick draws – you save herbs and battery, and the session lasts exactly as long as you want. Switching between modes is simple: just hold both temperature control buttons simultaneously for two seconds.
X-MAX V4 Pro Vaporizer – Glass Mouthpiece and Water Pipe Adapter in One
The V4 Pro features a magnetically attached glass mouthpiece that serves a dual purpose. During standard use, it delivers clean, unaltered vapor flavor – glass, unlike plastic, adds no aftertaste even at higher temperatures.
At the same time, the mouthpiece acts as a built-in water pipe (bong) adapter, fitting directly into 14.5mm and 18.8mm joints. No additional adapters needed – simply insert the mouthpiece into the bong joint and enjoy vapor filtered through water, which is noticeably cooler and gentler on the throat.
During a water pipe session, the image on the color OLED display can be flipped 180°, so you can read the temperature even when the vaporizer is upside down. It’s also worth noting that if you prefer the plastic or ceramic mouthpiece from the V3 Pro, both are fully compatible with the V4 Pro – as are dosing capsules and other accessories.
X-MAX V4 Pro Vaporizer – Color OLED Display and Precise Temperature Control
The X-MAX V4 Pro vaporizer features a color OLED display on the front of the device, replacing the older black-and-white screen from the V3 Pro. The screen is noticeably more readable – even in full sunlight – and shows all key information at a glance: current temperature, target temperature, active heating mode, and battery level.
Temperature is adjusted using two buttons below the display. You can set any value from 100°C to 220°C in 1°C increments, giving you full control over vapor intensity and flavor. This allows for vaporization of a wide range of different herbs, each with its own optimal vaporization temperature.
X-MAX V4 Pro Vaporizer – Replaceable 18650 Battery and USB-C Charging
A major advantage of the X-MAX V4 Pro – just like its predecessor – is its standard replaceable 18650 battery with a capacity of 2550 mAh. Replacing the battery takes literally a few seconds: simply unscrew the cap at the bottom of the device. The new screw-on cap design (replacing the magnetic one from the V3 Pro) provides a much more secure hold and eliminates the risk of accidental opening – one of the improvements users requested most often.
The USB-C charging port is located on the side of the device (rather than the bottom, as in the V3 Pro), allowing the vaporizer to stand upright while charging – a convenient and elegant solution. Standby mode activates automatically when the device is not in use, further conserving battery life.
X-MAX V4 Pro Vaporizer – Design and Build Quality
The X-MAX V4 Pro retains the slim pen-shaped form known from its predecessor, but with a noticeably more solid housing. Dimensions of 2.7 × 2.4 × 15.8 cm and a weight of just 107 grams mean the device easily fits in a pants pocket, jacket, or small bag. The matte finish gives the vaporizer an elegant, discreet appearance – it doesn’t attract unnecessary attention and looks like an ordinary electronic gadget.
How to Use the X-MAX V4 Pro Vaporizer
- Before first use, “season” the device by running it several times with an empty chamber at maximum temperature. This helps remove any residue from the manufacturing process.
- Grind the herbs to a medium-fine consistency – fine enough, but definitely not to a powder. Remove the glass mouthpiece and load the herbs into the chamber. Its concave shape means the material settles naturally. The chamber should be filled, but the herb should not be packed tight – air must be able to flow freely through it.
- Reattach the mouthpiece (magnets will hold it in place) and click the power button three times to turn on the vaporizer. Set your preferred temperature using the up/down buttons. We recommend starting at lower temperatures (around 170-180°C) and gradually increasing throughout the session.
- Wait about 11 seconds to heat up – the device will vibrate when ready. Draw through the mouthpiece. Due to the convective heating, the longer the inhale, the more vapor you’ll get – aim for 10-15 second draws.
- After the session, click the power button three times to turn off the device. Empty the chamber using the spatula built into the mouthpiece base and brush it with the included brush.
X-MAX V4 Pro Vaporizer – Cleaning and Maintenance
Daily maintenance of the X-MAX V4 Pro is quick and straightforward. After each session, simply wipe the chamber with the included brush. Every few sessions, it’s worth wiping the chamber with an isopropyl alcohol-soaked cotton swab to keep the flavor fresh.
The mouthpiece disassembles into five parts: glass tip, silicone holder, cap, filter, and screen. Thorough cleaning involves soaking all parts in isopropyl alcohol (e.g., VapeCleaner) for 10-20 minutes, rinsing with clean water, and leaving to dry. Before the next session, it’s worth running a full session at maximum temperature with an empty chamber to remove any alcohol residue.
Dosing capsules significantly simplify cleaning – herbs remain inside the capsule, so the chamber barely gets dirty. Spare screens are also included.
X-MAX V4 Pro Vaporizer – Who Is This Device For?
The X-MAX V4 Pro is a vaporizer recommended both for those just starting their vaping journey and for experienced users looking for a versatile device at a reasonable price.
Choose the X-MAX V4 Pro if you value clean, convective vapor flavor, want full control over airflow and operating mode, and appreciate a replaceable battery and water pipe compatibility without additional accessories. The V4 Pro is also discreet and compact enough to work great for users planning to use the device on the go.
Thanks to backward compatibility with V3 Pro accessories, users of the previous model can seamlessly transition to the newer version while keeping their collection of capsules, mouthpieces, and adapters.
