Hybrid Heating and Vapour Quality
The PAX FOUR combines conduction and convection to deliver fuller vapour and more even extraction than simpler models. Conduction heats the herb directly for fast, consistent results, while convection pulls hot air through the chamber with each draw, improving flavour and smoothness. The result is a more refined session from start to finish, with less guesswork for newer users.
Temperature Settings and Session Control
Control is simple but flexible, with four preset PAX FOUR temperature settings from 190 °C to 220 °C. This gives enough range to shape sessions without menus, screens, or apps.
Lower settings favour flavour and lighter draws, while higher ones boost vapour and extraction. The one-button interface, haptic feedback, and LED petals keep everything clear—the device vibrates at temperature, and the selected petal stays lit.


Design, Portability, and Everyday Use
At 125 g, the PAX FOUR is light enough for daily carry while still feeling solid. It keeps the familiar compact, pocket-friendly PAX shape, with a textured aluminium shell for added grip.
It slips easily into a pocket or bag and stays discreet for quick sessions. The flat mouthpiece keeps things low-profile, while the raised option offers more comfort for longer draws. Overall, it’s a portable, low-fuss device that fits easily into everyday use.


Battery Life and USB-C Charging Time
The 2800 mAh battery delivers up to 50 minutes of use, or roughly 4–5 sessions, depending on heat setting and draw style.
PAX FOUR charging time is around 90 minutes via USB-C, which is solid if not class-leading. Actual times may vary with your cable and power source. You can check battery levels by shaking the device; each lit LED petal represents about 25% charge.


How to Use the PAX FOUR
Getting started is straightforward, which is a big part of learning how to use PAX FOUR.
- Grind your herb and pack the oven evenly.
- Press the mouthpiece button to switch it on.
- Tap to choose a heat mode.
- Wait for the vibration, then inhale slowly.
- Empty and brush the chamber after use.
What You’ll Need
Set everything out before you begin so loading and using the device stays quick and tidy.
- PAX FOUR device
- Ground dry herb
- Fully charged battery
- Multi-tool for packing and emptying, if needed
Directions
- Remove the oven lid, fill the chamber with ground herb, lightly tamp, and replace the lid.
- Press the button to power on, then tap to select your heat mode.
- Wait 55–70 seconds for heat-up. The device vibrates when ready, and the LED petal confirms your setting.
- Take slow, steady draws for best results.
- Press and hold the button to power off when finished.


How to Clean and Maintain the PAX FOUR
Regular cleaning keeps the PAX FOUR performing as it should. A quick brush-out after each session helps preserve airflow, while deeper periodic cleaning removes residue that can dull flavour over time.
That small bit of upkeep also supports better long-term reliability, making the device easier to use and helping it last longer.
What You’ll Need
A few basic cleaning supplies are enough to keep the PAX FOUR in good shape.
- Isopropyl alcohol
- Cotton swabs or soft cleaning tools
- Wire brush
- Warm water
- Cloth or paper towel
Directions
- Brush the airpath after each session while warm to prevent residue build-up and keep airflow open.
- Periodically remove the oven screen and clean it with a small amount of isopropyl alcohol.
- Wipe the chamber and mouthpiece using a cotton swab or soft cleaning tool.
- Allow all parts to dry fully before reassembling the device.
- If using a silicone mouthpiece, refresh it with a quick damp wipe before use.


Main Benefits and Potential Drawbacks of the PAX FOUR
The PAX FOUR delivers a strong mix of performance and simplicity. Its hybrid heating is the standout feature, offering richer vapour and more even extraction than conduction-only models. It stays easy to use with one-button controls, no app, a compact 125 g body, and convenient USB-C charging.
The trade-offs are straightforward. There’s no display, so you rely on LED cues, and the preset temperatures limit precise control. It’s also a dry-herb-only device, which reduces versatility.
Overall, PAX FOUR prioritises ease of use, portability, and vapour quality over deep customisation.
