Can I use PAX Plus accessories with the PAX Four?

The mouthpieces are compatible. Dosing capsules and concentrate inserts do not work — the PAX Four has a different oven design and does not support concentrates.

Is it worth upgrading from the PAX 3 to the PAX Four?

Yes, if vapour quality is a priority. The hybrid heating is a significant upgrade. No, if you need app control, concentrates or maximum battery life — the PAX 3 has all of that, the PAX Four does not.

About this vaporizer

The PAX Four is the newest model in the PAX lineup, combining hybrid heating with a 2800 mAh battery for up to 50 minutes of runtime. Four temperature presets (190-220 degrees) are selected directly on the device — no app, as the PAX Four has no Bluetooth like the Flow. USB-C charging takes about 100 minutes.

At 125 grams, it is even lighter than the PAX Flow (135g) and retains the compact PAX design. The chamber holds roughly 0.3g. According to PAX, the Four delivers 50% more vapor than the PAX Mini, PAX 3 and PAX Plus. No water pipe compatibility, no dosing capsule support.

At $250 MSRP, the PAX Four offers the best value in the current PAX lineup: more battery than the Flow, similar vapor quality, $100 cheaper. The 2-year warranty extends to 3 years with registration.

The PAX Four is the flagship from PAX Labs (2026) and the first PAX with hybrid heating (conduction + convection). 50 % more vapour than PAX 3 and PAX Plus according to the manufacturer. Four temperature levels (190-220 °C), 2800-mAh battery, USB-C charging in ~90 minutes. No app, no Bluetooth — deliberately kept simple. Lightweight at 125 g, fits in any jacket pocket. From €199 in 68 shops across 19 countries.

Hybrid heating: The biggest difference

The PAX Four combines conduction (bottom heat) with convection (hot air when drawing). The result: denser, more aromatic vapour from the first draw. Four temperature levels cover the range: 190°C for flavour, 200°C for balance, 210°C for dense clouds and 220°C for maximum extraction. Slow, even draws over 6-8 seconds work best.

Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that vaporisation at controlled temperatures releases über 95 % of the desired active compounds, while combustion by-products are largely avoided. Source: PubMed 16637053

How Do I Charge the Battery Properly?

2800 mAh is enough for around 50 minutes of active use or about 5 sessions. USB-C charging takes approximately 90 minutes. Passthrough charging works — the vaporizer can be used while charging. Less than the 3500 mAh of the PAX 3, but the hybrid oven needs more energy.

How Portable and Ergonomic Is the Design?

Aluminium housing, lightweight at 125g, two mouthpieces (flat + raised). One button controls everything — on/off, temperature change, session start. Haptic feedback confirms actions. No display, no app. The funnel-shaped oven holds 0.3g and is easy to fill. Clean every 3-4 sessions with the included wire brush.

First session: How to get started

1) Fully charge the device (USB-C, ~90 min). 2) Fill the oven with a medium-fine grind (0.2-0.3g, tamp lightly). 3) Press the button 2x to switch on. 4) Start with Mode 1 (190°C) for pure flavour. 5) Draw slowly and evenly, 6-8 seconds per draw. 6) After the session, empty the oven with the brush. Tip: The first 2-3 draws of each session deliver the most flavour.

Comparison with other devices

Crafty+ (€209): Has app control and cooling unit, ~10g heavier. Solo 3 V2 (€219): 3× battery life, glass stem, lifetime warranty. Mighty+ (€279): Best vapour quality with legendary cooling system, but 230g. The PAX Four wins on portability and simplicity — for the price of €199, a fair offer.

How Do I Clean and Maintain My Vaporizer?

Clean the oven every 3-4 sessions with the included wire brush and multi-tool. Use isopropyl alcohol on a cotton bud for the vapour path, once per week. Regularly soak the mouthpieces in Iso (15 minutes). The funnel-shaped oven collects less residue than older PAX models.
