Full Convection System — The V4 Pro's Standout Feature

Full Convection Heating

The heart of the XMAX V4 Pro is its Full Convection heating system where hot air flows through the herb for even extraction and thorough vaporization. Unlike hybrid systems, the V4 Pro relies entirely on convection for superior flavor and efficiency

The result is thick, flavorful vapor with efficient extraction from the first draw to the last.

Temperature Range: 100-220 C

The V4 Pro offers a temperature range from 100 to 230 degrees Celsius, covering every vaping style:

• 100-170 C — Low temperatures for flavor chasers, light and tasty vapor
• 170-200 C — Medium temperatures balancing flavor and cloud density
• 200-220 C — High temperatures for thick, potent clouds and maximum extraction

Vapor Quality

The vapor quality of the XMAX V4 Pro is excellent for a device in this price range, thanks to the Full Convection system:

• Dense vapor from the very first draw, no waiting for the device to catch up
• Clean flavor with clear herb taste profiles
• Smooth and cool thanks to the mouthpiece design
• Even extraction with uniformly browned herb after sessions

Compared to the V3 Pro, which uses Full Convection, the V4 Pro delivers noticeably better vapor in both density and flavor.

2550mAh Removable Battery

2550mAh Capacity — Multiple Sessions Per Charge

The XMAX V4 Pro uses a 2550mAh lithium-ion battery, providing approximately 6-8 sessions per full charge (depending on temperature settings).

Removable Battery — A Rare Feature

One of the standout features of the V4 Pro is its removable battery, a feature rarely found in portable vaporizers. This means:

• Buy a spare battery and swap it in instantly, no waiting for a recharge
• When the battery degrades over time, simply replace it without repairing the entire device
• Extends the lifespan of your vaporizer by years

Charging via USB-C takes approximately 2-3 hours from 0 to 100%.
