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.

From $174 across 68 shops in 19 countries.

Hybrid Heating: The Biggest Difference

The PAX Four combines conduction (bottom heat) with convection (hot air during draws). Result: denser, more flavorful vapor from the first draw. Four temperature presets: 190°C for flavor, 200°C for balanced vapor, 210°C for thick clouds, and 220°C for maximum extraction. Slow, steady pulls 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 over 95% of target compounds while largely avoiding combustion by-products. Source: PubMed 16637053

How Do I Charge the Battery Properly?

2800 mAh provides about 50 minutes of active use or roughly 5 sessions. USB-C charging takes around 90 minutes. Passthrough charging works — you can vape while plugged in. Less than the PAX 3's 3500 mAh, but the hybrid oven requires more power for the convection element.

Design and Feel

Aluminum shell, 125g weight, two mouthpieces (flat for pocket carry, raised for airflow). Single button controls everything — power, temperature cycling, session start. Haptic feedback confirms each action. No screen, no app, no Bluetooth. The funneled oven holds 0.3g and loads easily. Clean every 3-4 sessions with the included wire brush.

First Session: Getting Started

1) Fully charge the device (USB-C, ~90 min). 2) Fill the oven with medium-ground herb (0.2-0.3g, light tamp). 3) Press button twice to power on. 4) Start with Mode 1 (190°C) for pure flavor. 5) Draw slowly and steadily, 6-8 seconds per pull. 6) After the session, brush out the oven. Tip: The first 2-3 draws of each session deliver the best flavor.

How It Compares

Crafty+ (~$209): Has app control and cooling unit, ~10g heavier. Solo 3 V2 (~$219): 3× battery life, glass stems, lifetime warranty. Mighty+ (~$279): Best vapor quality with legendary cooling system, but 230g. The PAX Four wins on portability and simplicity — at $174-250 depending on region, it's fairly priced.

How Do I Clean and Maintain My Vaporizer?

Brush the oven every 3-4 sessions with the included wire brush and multi-tool. Use isopropyl alcohol on a cotton swab for the vapor path once per week. Soak the mouthpieces in iso regularly (15 minutes). The funneled oven collects less residue than older PAX models.

Frequently Asked Questions

Can I use PAX Plus accessories with the PAX Four? +

Mouthpieces are compatible. Dosing capsules and concentrate inserts won't work — the PAX Four has a different oven design and doesn't support concentrates.

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

Yes if vapor quality is your priority. Hybrid heating is a clear upgrade. No if you need app control, concentrate compatibility, or maximum battery life — the PAX 3 has all of those, the PAX Four doesn't.
