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 PAX Labs' 2026 flagship and their first hybrid vaporizer (conduction + convection). 50% more vapor than PAX 3 and PAX Plus according to the manufacturer. Four temperature presets (190-220°C), 2800 mAh battery, USB-C charging in ~90 minutes. No app, no Bluetooth — deliberately simplified. At 125g, it fits into any jacket pocket. 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.

PAX Four vs PAX Plus

The PAX Four and PAX Plus represent two different approaches from PAX Labs. Here's how they compare:

Feature	PAX Four	PAX Plus
Price	from 150	from 91
Heating	Hybrid (conduction + convection)	Conduction only
Battery	2800 mAh	3300 mAh ✓
Max Temp	220°C ✓	215°C
Weight	125g	91g ✓
Warranty	2 years	10 years ✓
Passthrough	Yes	Yes

Our verdict: Choose the PAX Plus if you want the best value — longer battery, lighter weight, and an industry-leading 10-year warranty for ~60€ less. Choose the PAX Four if you prioritize vapor quality and want hybrid heating technology for denser, more flavorful vapor from the first draw.

Key differences explained:

Hybrid vs Conduction: The PAX Four adds hot air (convection) during draws, producing thicker vapor with better flavor extraction. The PAX Plus uses pure conduction, which works well but takes longer to extract.
Battery life: Despite hybrid heating's higher power draw, both devices last about 50-60 minutes. The PAX Plus has 500 mAh more capacity.
Warranty: The PAX Plus comes with PAX's legendary 10-year warranty. The PAX Four only has 2 years — a significant difference for a ~170€ device.

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.
