XMAX V3 Pro vs V4 Pro: What Actually Changed

Short answer: the XMAX V4 Pro is the V3 Pro with three specific upgrades — a colour OLED screen instead of a monochrome one, an adjustable airflow control the V3 Pro does not have, and a redesigned battery hatch. Everything else that matters is identical: same 100–220 °C range, same removable 18650 battery, same stainless steel chamber, same USB-C charging, same on-demand and session modes.

That matters because the V3 Pro is one of the most searched dry herb vaporizers in New Zealand, and most of what you will read comparing it to the V4 Pro is guesswork. So here is the comparison built only from what the manufacturer publishes. XMAX devices are made by TopGreen Technology, and the figures below come straight off TopGreen's own product pages, read on 26 August 2026.

XMAX V3 Pro vs V4 Pro: the specification table

Both sit in the affordable half of the dry herb vaporizer range, with the V4 Pro carrying a modest premium over the V3 Pro. Current New Zealand prices are on the two product pages linked above — we do not print prices in guides, because they change and a stale number is worse than no number.

The three differences that actually matter

1. Adjustable airflow is the real upgrade

This is the change worth paying for. The V4 Pro carries an airflow adjustment; the V3 Pro does not list one. On a convection device, restricting or opening the airway changes how dense and how warm the draw feels far more directly than nudging the set temperature does. If you have used a V3 Pro and found the draw either too tight or too airy for your taste, the V4 Pro gives you a control for exactly that. If you have never thought about your draw resistance, this feature will not change your life.

2. The colour screen is convenience, not performance

Both devices have a large OLED display showing temperature and battery. The V4 Pro's is in colour. It is easier to read at a glance and it looks better. It does not make vapour. Treat it as a nice-to-have, not a reason to upgrade.

3. The battery hatch was redesigned

Both devices use a removable 18650 cell, which is the single best design decision in either — a vaporizer with a swappable battery has a much longer usable life than one with a sealed cell, because a flat battery is a five-dollar problem instead of a dead device. The V4 Pro revises the hatch that holds it. Same battery, easier access.

What did not change

Temperature range, heating method, chamber material, charging, modes and the isolated airpath are identical on paper. Anyone telling you the V4 Pro is a fundamentally different vaporizer is over-selling it. It is a careful revision of a device that was already good, not a redesign.

Which one should you buy?

Buy the V3 Pro if you are buying your first dry herb vaporizer

It is the cheaper of the two, it has the same temperature range and the same removable battery, and it is the model with by far the largest body of New Zealand customer feedback behind it — several hundred reviews on our product page alone. For someone finding out whether a portable convection device suits them at all, spending less to find out is the correct move. See the V3 Pro.

Buy the V4 Pro if you already know you want airflow control

Two groups should go straight to the V4 Pro. First, anyone replacing a V3 Pro who has specific complaints about draw resistance — the airflow slider is the fix. Second, anyone who plans to use the device daily and would rather have the better screen and the improved hatch from the outset than upgrade later. See the V4 Pro.

Do not upgrade a working V3 Pro just for the screen

If your V3 Pro works and the draw suits you, the V4 Pro will not give you better vapour. Buy a spare 18650 battery and a fresh mouthpiece instead — that is a fraction of the cost and it fixes the two things that actually degrade on these devices over a couple of years.

Accessories and spares

The replacement 18650 cell stocked here is listed as fitting both the V3 Pro and the V4 Pro, so a spare battery is not wasted if you upgrade later. Mouthpieces are model-specific: there is a glass mouthpiece for the V3 Pro and a 2-in-1 mouthpiece and adapter for the V4 Pro. There is also a glass waterpipe adapter for the V3 Pro if you want to run the device through existing glassware. The rest of the range sits in the Xvape and XMAX collection and the wider vaporizer accessories collection.

FAQ

Is the XMAX V4 Pro worth the extra money over the V3 Pro?

If you will use the adjustable airflow, yes. If you are buying your first device and do not yet have opinions about draw resistance, the V3 Pro gives you the same temperature range, the same battery and the same chamber for less.

Do the V3 Pro and V4 Pro use the same battery?

Yes. Both use a removable 18650 3.7 V 2550 mAh cell, and the replacement battery stocked here is listed for both models. Mouthpieces and accessories are not interchangeable in the same way, so check the model name on any part before ordering.

How long do they take to heat up?

TopGreen does not publish a heat-up figure on the product pages for either model, so we are not going to quote one. Both are convection devices with on-demand and session modes; the session timer on the V3 Pro is selectable between four and six minutes.

What is an isolated airpath and why is it on the spec sheet?

It means the air you draw through the device does not pass over the electronics or the internal housing — it travels through the chamber and out the mouthpiece only. TopGreen lists it for both models. It is a build-quality point, and it also makes cleaning simpler because residue collects in fewer places.

Which XMAX is best for use with a waterpipe?

Either, with the right adapter. The V3 Pro has a dedicated glass waterpipe adapter; the V4 Pro's 2-in-1 mouthpiece is sold with adapter functionality. Check the fitting size of your existing glass before ordering.

Where do these sit against the premium brands?

XMAX competes on value: removable batteries, real convection and a wide temperature range at a fraction of the price of German-made devices. If you want to see how they compare against the premium end, our Storz & Bickel buyer's guide covers that range, and the Xvape range guide covers the rest of the XMAX line-up.
