Xmax V4 Pro Vaporizer

Xmax V4 Pro Vaporizer UK: Full Convection, Total Control

The Xmax V4 Pro is a full-convection dry herb vaporizer with precise 1°C temperature control, a replaceable battery, and both session and on-demand modes. At its price point, it is one of the most capable portable vaporizers available in the UK — proof that you do not need to spend three figures to get genuinely excellent dry herb vapour. If you want the best budget dry herb vaporizer in the UK under £100, the V4 Pro deserves a serious look.

It builds on the hugely popular Xmax V3 Pro with several meaningful upgrades: adjustable airflow, an on-demand heating mode, a faster heat-up and a built-in water-pipe adapter. Everything that made the V3 Pro a favourite, refined and expanded.

Key Features

Full Convection Heating

Full convection means hot air passes evenly through your dry herb rather than heating the chamber walls directly. The payoff is cleaner extraction, better flavour preservation and more efficient use of your material compared to conduction-based vaporizers. Air is drawn through the chamber and over your herb from every side, for rich, even vapour from the first draw to the last.

Adjustable, Isolated Airflow

A built-in airflow slider on the body lets you fine-tune your draw resistance. Tighten it for a denser, warmer hit; open it up for a lighter, cooler one. Just as importantly, the airpath is fully isolated, so your vapour never touches plastic or silicone on its way to you — only stainless steel and the pure taste of your herb. It is a clean, considered design that makes a real difference to flavour.

Session And On-Demand Modes

The V4 Pro's dual-mode heating is rare at this price and one of its strongest selling points. Session mode keeps the chamber at temperature for a set period — ideal for relaxed, consistent sessions at home. On-demand mode heats only while you draw, preserving material and battery and giving quick, efficient draws on the go. Switch between the two to suit the moment.

OLED Display With Precise Controls

A large colour OLED screen shows your set temperature, current temperature, battery level and session timer at a glance. Temperature is adjustable in precise 1°C increments across a 100°C to 220°C range, so you can dial in exactly the experience you want — lower for flavour, higher for clouds.

Replaceable Battery And USB-C Charging

The V4 Pro runs on a standard 18650 battery (one included) with USB-C charging. Because the battery is removable, you can carry a spare and swap it in seconds for effectively unlimited sessions — something built-in-battery devices simply cannot offer. It is a genuine, practical advantage for anyone heading out for the day or travelling, and USB-C means fast, convenient top-ups when you do charge.

Built-In Water-Pipe Adapter

The V4 Pro includes a 14mm/18mm water-pipe adapter, so you can connect it to a bubbler or water piece for even cooler, smoother draws. If you love a glass-cooled hit, it is built in from the box — no extra purchase needed.

Design And Portability

The V4 Pro keeps the slim, pen-style form factor that made the V3 Pro so easy to carry. It is lightweight, discreet and fits comfortably in a jacket pocket or small bag, while the ceramic chamber ensures clean heating and clean flavour without adding unnecessary bulk.

How To Use The Xmax V4 Pro

1. Grind your dry herb and load the ceramic chamber.
2. Power on, choose session or on-demand mode, and set your temperature.
3. Wait around 11 seconds for it to reach temperature.
4. Set the airflow to taste and draw — or attach the water-pipe adapter for a cooler hit.

Maintenance And Cleaning

The ceramic chamber cleans up easily with isopropyl alcohol on a cotton swab. Empty loose material after sessions, give the airpath a clean weekly with regular use, and the V4 Pro will keep delivering clean, flavourful vapour for the long haul.
