PAX 4 Vaporizer UK – Powerful Dry Herb Vape

The PAX FOUR, also known as the PAX 4, is the latest generation of PAX's pocket-sized dry herb vaporizer range and the most powerful PAX device released to date. Designed for users who want denser vapour without moving to a bulky desktop device, the PAX FOUR combines a new high-output hybrid heating system with PAX's familiar minimalist design and straightforward controls.

PAX says the FOUR produces up to 50% more vapour than previous PAX models, specifically compared with the PAX 2, PAX 3, PAX PLUS, PAX MINI and PAX FLOW. The new heating architecture is designed to provide stronger output while maintaining a smooth draw and avoiding combustion.

The redesigned oven, four heat modes, real-time temperature control, USB-C charging and compact form factor make the PAX FOUR an appealing option for UK customers who want a powerful dry herb device without complicated operation.

Available in Onyx and Greenstone, the PAX FOUR keeps the understated PAX look while introducing the biggest performance-focused change the range has seen in years.

Temperature Settings & Heat Modes

The PAX 4 Vaporizer includes four intelligent preset heat modes designed for different session styles. Thanks to real-time temperature control, the device automatically adjusts heat output while you inhale, ensuring consistent and efficient vapour production.

• Mode 1 – Low Temp: Smooth, flavour-focused draws with lighter vapour.
• Mode 2 – Balanced: A mix of flavour and moderate cloud production.
• Mode 3 – Boost: Thicker vapour with stronger intensity.
• Mode 4 – High Output: Maximum cloud production and potency.

Simply press the top button to cycle through modes. LED indicators and vibration feedback confirm when your device is ready.

USB-C Charging

USB-C is another significant improvement over previous PAX generations.

The PAX FOUR uses USB-C charging and provides up to five sessions or approximately 50 minutes of runtime per full charge, depending on how it is used. PAX's support documentation lists charging from empty at approximately 90 minutes.

For UK users already carrying USB-C equipment, the move away from the older proprietary charging approach is particularly convenient.

A dedicated PAX USB-C Fast-Charging Wall Charger is also available for customers who want a dedicated charging setup.

PAX FOUR Battery Life

PAX rates the FOUR for up to 50 minutes of runtime or approximately five sessions from a full charge.

Actual runtime varies according to the selected heat mode and usage. PAX specifically notes that higher heat modes use more battery while producing more vapour, so users who consistently select the higher settings should expect battery consumption to increase.

The device's battery status can be checked through the PAX interface, keeping charge information readily accessible during normal use.

PAX FOUR vs. PAX PLUS vs. PAX MINI

For customers deciding between PAX's current and previous compact dry-herb models, the key differences are centred on heating technology, power, charging and overall capacity.

PAX's current materials confirm the FOUR's dimensions, redesigned oven, USB-C charging, four heat modes, increased vapour output and lack of compatibility with the PAX Concentrate Insert.

Which PAX Vaporizer Is Right for You?

Choose the PAX FOUR if your priority is the strongest vapour production in the PAX range, a hybrid heater, four heat modes, USB-C charging and the latest oven design.

Choose the PAX PLUS if you prefer the established PAX design and want compatibility with the PAX Concentrate Insert.

Choose the PAX MINI if you prefer a smaller PAX format and a simpler dry-herb experience.

For customers who want to compare the FOUR with devices outside the PAX ecosystem, the XMAX V3 Pro offers removable-battery operation and electronic heating modes, while the Arizer Air MAX takes a different approach with its glass aroma tube and replaceable high-capacity battery.

PAX FOUR vs Other Compact Dry Herb Vaporizers

The PAX FOUR is designed around a discreet, pocket-friendly experience with a flush mouthpiece and simple operation.

An alternative such as the XMAX V3 Pro is more focused on user control, with electronic session and on-demand heating and a removable battery. The Arizer Air SE takes another route, pairing a lightweight body with a removable 18650 battery and Arizer's glass aroma-tube design.

This means choosing between them is less about which device is universally "best" and more about which approach suits your routine: maximum PAX output, greater electronic control, or an all-glass Arizer-style vapour path.

PAX FOUR Accessories

The FOUR has its own growing accessory ecosystem.

For charging, the PAX USB-C Fast-Charging Wall Charger provides a dedicated power option.

For cleaning and maintenance, the PAX Premium Maintenance Kit is designed specifically for PAX devices.

For mouthpiece preference, replacement PAX FOUR Raised Mouthpieces and PAX FOUR Flat Mouthpieces are available separately.

A replacement PAX FOUR Oven Lid is also available for long-term ownership.
