XMAX V4 Pro: Microdosing

The XMAX V4 Pro is a portable convection vaporizer for dry herbs from XMAX (Topgreen Technology). It offers an OLED display, a replaceable 18650 battery, three-stage airflow, a full-glass vapour path and a temperature range from ≤ 220 °C in 1° increments.

Pure convection. Hot air flows through the herbs without the material directly touching the heating element. This produces a clearer, more terpene-focused flavour than conduction or hybrid heating — the latter also heat the material via wall contact.

In Session mode, it reaches the target temperature in around ≈ 10 seconds. That is not the fastest heat-up time on the market — Tinymight 2 or Sticky Brick need around 3 seconds — but for OLED-controlled pure convection with 1° increments, it is a good figure. In On-Demand mode, vapour production begins after a few seconds of pressing the button.

Yes, the V4 Pro uses a standard 18650 battery (2,550/2,600 mAh (manufacturer pages conflict)) in a flat-top design without protection circuit. The battery can be removed in seconds via a screw-cap cover at the bottom end of the device and swapped for a fresh one. Recommended models: Samsung 25R, Sony VTC6 or Molicel P26A. Replacement batteries cost about 6 to 12 Euro.

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 filling on the go much easier and reduce cleaning effort, as plant-material residues remain in the capsule and not 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 also work. Water filtration cools the vapour down further and delivers smoother draws, especially at higher temperatures.

The V3 Pro uses hybrid heating with a ceramic vapour path, while the V4 Pro uses pure convection with a full-glass vapour path. The V4 Pro heats faster (11 instead of 15 seconds), has OLED in 1° increments, a magnetic glass mouthpiece with native WPA and dosing-capsule support. The V3 Pro has 2 instead of 1 year warranty and is slightly lighter (107 g vs not published by the manufacturer). Detailed comparison: XMAX V3 Pro vs V4 Pro.

Three draw-resistance stages from tight to open vary the ratio of vapour density to vapour volume. A tight setting emphasises flavour with small vapour volume and concentrated clouds. An open setting delivers larger clouds with lighter draw resistance and suits higher temperatures or water-filter setups. This allows the draw style to be adjusted individually.

The chamber holds around 0.1 to 0.15 g. For optimal convection, it should be filled 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-piece grinder.

At the lowest price, the Crafty+ costs about twice as much and offers hybrid heating with app control as well as 2 instead of 1 year warranty. If app boost mode, brand heritage from Tuttlingen and a longer manufacturer warranty are important to you, and you accept the significantly longer 60-second heat-up time, the surcharge is worth it. If pure convection with a clearer flavour profile, faster heat-up time and a replaceable battery are more important to you, the V4 Pro is the rational choice.

If you follow simple rules, replacement is safe: always transport the battery in a battery case (no direct contact with coins or keys in your pocket), buy only branded cells from Samsung, Sony or Molicel, and do not use batteries with damaged wrapping. The device itself has a protection circuit; that is also why “unprotected” flat-top batteries are the right choice (protected batteries are too long). Fake batteries from unclear sources carry a real risk — so buy only from authorised dealers.
