Who is the V4 Pro for?
The V4 Pro suits users seeking convection, a replaceable battery and both operating modes. Adjustable airflow and the glass/ABS mouthpiece are reasons to consider it alongside the V3 Pro. Existing V3 Pro owners should weigh the upgrade against those specific features.
Pure convection and stainless steel air path
The V4 Pro works with a stainless steel chamber through which hot air flows without the plant material making direct contact with the heating surface. This pure convection produces vapour only during a draw — between draws the material remains largely unchanged. By contrast, hybrid heaters (such as the Crafty+ or Mighty+) also heat the material passively via wall contact; conduction heaters (such as the DaVinci IQ3) heat it entirely through wall contact.
Why pure convection shapes the flavour profile
Pure convection delivers, based on general experience within the vaporizer community, a cleaner, more terpene-forward flavour profile at lower temperatures (170 to 185 °C). At higher temperatures (200 °C and above) denser vapour clouds are produced, without the material being overloaded beforehand by constant wall contact.
Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that controlled vaporization at temperatures below the combustion threshold releases over 95 % of the relevant active compounds whilst largely avoiding combustion by-products. Source: PubMed 16637053
Stainless steel air path with glass-ABS mouthpiece
The air path is made of stainless steel and the mouthpiece of glass and ABS. Glass is chemically inert and imparts no flavour of its own — unlike PEI plastic, aluminium or uncoated ceramic. The removable glass mouthpiece can be soaked in isopropyl alcohol for cleaning and rinsed several times a week without any flavour memory building up.
≈ 10 seconds heat-up time: what it means
The V4 Pro reaches the target temperature in around ≈ 10 seconds. That is not the fastest heat-up time on the market — pump-action vaporizers (Sticky Brick Junior at around 3 seconds), inductively heated devices (Tinymight 2 at around 3 seconds), or butane vaporizers (VapCap M with a lighter, instant) are physically faster. The desktop Tafee Bowle also reaches temperature in 1 second, but is not a portable in the strict sense (246 g, large battery platform).
Realistic positioning among the competition
Compared to digitally controlled convection portables in the sub-€200 class with OLED or LCD displays, the V4 Pro sits in the upper mid-field: the XMAX V3 Nano takes 15 seconds, the XMAX Fog Pro 15 seconds, and the XVape Vista Mini 2 likewise 10 seconds (though conduction). For an OLED-controlled pure convection device with 1° steps in this price range, ≈ 10 seconds is a solid figure.
What you can do in ≈ 10 seconds
≈ 10 seconds is enough to briefly set the V4 Pro down after switching it on, take a sip of your drink, or loosely distribute the material in the chamber. It is not an "instant session" as a 3-second convection device or a butane vaporizer would be — but it is no longer "kettle-watching" either, as with 60-second hybrid heaters (Crafty+, Mighty+).
Removable 18650 battery with 2,550/2,600 mAh (manufacturer pages contradict each other)
The V4 Pro uses a standard 18650 lithium-ion battery with 2,550/2,600 mAh (manufacturer pages contradict each other). The battery is not permanently built in; it can be removed via a screw-cap cover at the bottom of the housing. This design has three practical consequences:
- Outdoor sessions without a power socket: A second charged 18650 battery in your pocket is enough for the second half of a hiking day or a longer event.
- Compensating for battery ageing: Lithium-ion batteries lose a noticeable amount of capacity over 300 to 500 charge cycles. With permanently built-in batteries, that means noticeably shorter sessions after 2 to 3 years. With the V4 Pro, you simply swap the battery for €6 to €12.
- Charging: The V4 Pro charges via USB-C; TopGreen makes no statement about operation whilst charging. With a heavily discharged battery, this is a convenient solution at a desk.
Sessions per charge (real-world figures)
According to TopGreen, a full charge delivers at least 12 sessions of 6 minutes each at 220 °C; the session timers run for 4 or 6 minutes. A full charge via USB-C takes around 3 hours at 1 A according to the manufacturer (4 to 5 hours at 0.5 A); chargers above 5 V/2 A will stop the charging process.
What Are the Ideal Temperature Settings?
TopGreen specifies 100–220 °C. A device setting is not a universal recommendation for every material. Follow the manual; flavour and vapour output also depend on loading and use.
Check dosing capsule compatibility
For separately sold capsules, check explicit V4 Pro compatibility. The XMAX name alone does not establish fit. Also check whether capsules are included in the selected bundle or cost extra.
How Do I Adjust the Airflow?
The side slider adjusts draw resistance. The previous description of three fixed stages was not supported by the manufacturer information. Use it to adjust the draw to your preference; it does not establish a particular vapour quality.
Session and on-demand
The manufacturer FAQ specifies four- or six-minute sessions. In on-demand mode, hold the function button to heat. Follow your device version’s manual for button combinations and display indicators.
Pen Design and Portability
The slim housing and the replaceable 18650 battery make the V4 Pro travel-friendly. The verified manufacturer page states no reliable device weight; we therefore publish no weight in grams here.
Follow manufacturer cleaning instructions
Let the device cool before maintenance. Distinguish glass, ABS and filter components; a blanket alcohol-soak instruction for the entire mouthpiece is not adequately supported. Follow the linked manufacturer guidance for each part and keep liquids away from the electronic device.
Water pipes and accessory costs
TopGreen describes a 14 mm mouthpiece connection. Check your water pipe size and actual retailer bundle before ordering additional adapters. Generic recommendations for any 18650 cell or standard capsule do not replace device-specific compatibility.
Manufacturer and service
XMAX is a TopGreen brand. Check who handles service and which terms apply to your chosen offer. A brand name or manufacturing location alone does not establish warranty handling.
Check warranty coverage before buying
The linked product and support information does not clearly establish one manufacturer warranty for every retailer offer. Check duration, claims handling and coverage of batteries and wear parts with the seller. A blanket one-year claim is not a reliable basis for choosing an offer.
18650 Battery Safety
The V4 Pro uses an 18650 lithium-ion battery in a flat-top form factor without an integrated protection circuit ("unprotected"). This is a deliberate choice by Topgreen: the protection circuit sits within the device itself, which allows for shorter batteries and reduces heat build-up at the battery.
Recommended Battery Types
- Samsung 25R — proven industry standard, sufficient current output
- Sony VTC6 — higher current output, slightly higher capacity (3,000 mAh)
- Molicel P26A — good headroom, suitable for intensive use
Safety Rules for Battery Changes
- Never use a battery with a damaged wrap — even small cuts or dents are a fire risk.
- Always transport batteries in a dedicated battery case — direct contact with keys or coins in your pocket can cause a short circuit.
- Pay attention to correct polarity when changing — positive towards the display, negative towards the base (or as indicated on the device). The device does have reverse polarity protection, but caution is more reliable than electronics.
- Buy batteries from reputable sources — brand-name units from Samsung, Sony, and Molicel are only guaranteed to be genuine through authorised retailers. Counterfeit batteries of unknown origin are a real safety risk.
What You Should Not Do
Do not use "protected" 18650 batteries with an additional protection circuit — these are often longer than the standard and will not fit mechanically. Do not use button-top batteries — the current draw in the device is optimised for flat-top. Never charge damaged batteries.
Operating guidance
Use the manufacturer manual for controls and charging. Undocumented button combinations or supposed performance boosts are not a reliable basis for a purchase decision.
Buying decision: V4 Pro or V3 Pro?
Compare the XMAX V3 Pro if a replaceable battery and two modes are your main requirements. The V4 Pro becomes more relevant if you want adjustable airflow. Compare delivery country, stock, shipping and included accessories before choosing a retailer.

The XMAX V4 Pro is a portable convection dry-herb vaporizer by XMAX (Topgreen Technology). It features an OLED display, a replaceable 18650 battery, adjustable airflow, a stainless-steel air path with a glass-ABS mouthpiece, and a temperature range of ≤ 220 °C in 1° increments.
Pure convection. Hot air passes through the herb without the material touching the heating element directly. This produces a cleaner, more terpene-forward flavour than conduction or hybrid heating — the latter also warm the material via wall contact.
In session mode it reaches the target temperature in approximately ≈ 10 seconds. That is not the fastest heat-up time on the market — the Tinymight 2 or Sticky Brick take around 3 seconds — but for an OLED-controlled pure convection device with 1° increments it is a solid figure. In on-demand mode vapour production begins after a few seconds of button press.
Yes, the V4 Pro uses a standard 18650 battery (2,550/2,600 mAh (manufacturer pages contradict each other)) in a flat-top configuration without a protection circuit. The battery can be removed in seconds via a screw-cap cover at the bottom of the device and swapped for a fresh one. Recommended models: Samsung 25R, Sony VTC6, or Molicel P26A. Replacement batteries cost roughly £6 to £12.
Yes, the V4 Pro is compatible with standard dosing capsules. The capsules fit directly into the chamber and hold around 0.1 to 0.15 g of plant material. They make loading on the go considerably easier and reduce cleaning effort, as plant-material residue stays in the capsule rather than in the chamber.
Yes. The magnetic glass mouthpiece is a native 14 mm water-pipe adapter and fits directly into 14 mm bong joints. With a 14-to-18 mm reducer, 18 mm connections work as well. Water filtration cools the vapour further and delivers smoother draws, especially at higher temperatures.

Both use pure convection: the V3 Pro routes vapour through a stainless-steel chamber with a ceramic air path, the V4 Pro through a stainless-steel air path. According to TopGreen, both heat up in around 10 seconds (20 at most), have an OLED display with 1° increments, a magnetic glass mouthpiece with a native WPA, and dosing-capsule support. The manufacturer states a 12-month warranty for the V3 Pro; tests measure 105 g; for the V4 Pro the manufacturer publishes no weight; the manual states a twelve-month warranty. Detailed comparison: XMAX V3 Pro vs V4 Pro.
Three airflow resistance levels from tight to open vary the ratio of vapour density to vapour volume. A tight setting emphasises flavour with a smaller vapour volume and concentrated clouds. An open setting delivers larger clouds with less draw resistance and suits higher temperatures or water-filter setups well. This allows the draw style to be tailored individually.
The chamber holds around 0.1 to 0.15 g. For optimal convection it should be packed loosely so that air can flow through evenly. Packing too tightly restricts airflow and reduces vapour output. Use a medium grind, ideally with a four-chamber grinder.
The Crafty+ costs roughly double the lowest price and offers hybrid heating with app control as well as a 2-year rather than 1-year warranty. If the app boost mode, brand heritage from Tuttlingen, and the longer manufacturer warranty matter to you and you can accept the considerably longer 60-second heat-up time, the premium is worth it. If pure convection with a cleaner flavour profile, faster heat-up time, and a replaceable battery are more important to you, the V4 Pro is the rational choice.
When a few simple rules are followed, swapping the battery is safe: always carry the battery in a battery case (no direct contact with coins or keys in your pocket), only buy branded cells from Samsung, Sony, or Molicel, and never use batteries with a damaged wrap. The device itself has a protection circuit; this is also the reason why "unprotected" flat-top batteries are the right choice (protected batteries are too long). With counterfeit batteries from an unknown source there is a real risk — so only buy from authorised retailers.
