VapeExperts Review of the XMax V4 Pro
The XMax V4 Pro is the top-value convection portable VapeExperts has tested as of May 2026. It takes the foundation of the XMax V3 Pro7.5, our long-standing pick on the best budget vaporizers ranking, and adds 3-position adjustable airflow, a 150% larger oven, a glass-and-ceramic vapor path, and an on-demand mode while keeping the replaceable 18650 battery that made the original a hit.
We scored it 7.8 overall with a standout 9.0 for value. That gap between a modest overall score and a chart-topping value rating tells the whole story: this vape overdelivers for what you pay. Build quality and the 220°C temperature ceiling keep it out of the top tier, but nothing else in this price bracket packs this many features into 120 g.
What's in the Box
XMax includes the essentials without filler. Inside you'll find the V4 Pro, a USB-C charging cable, one dosing capsule, a cleaning brush, replacement O-rings and screens, and the user manual.
The borosilicate glass mouthpiece doubles as a water pipe adapter that fits standard 14 mm joints. That inclusion saves you from a separate WPA purchase that most competitors at this price require.
120 g aluminum body with a glass vapor path
The V4 Pro uses an anodized aluminum shell measuring 119 x 34 x 28 mm and weighing 120 g. That's 15 g heavier than the V3 Pro but still lighter than most portables with adjustable airflow in this price class. The slim cylindrical shape slides into a front jeans pocket without a visible bulge.
The borosilicate glass mouthpiece is a clear step up from the V3 Pro's zirconia ceramic tip. It pops out for cleaning and drops directly into a water piece. A color OLED display shows temperature, battery level, and session timer, with a screen-flip function for left-handed users.
Build quality scored 7.3, the V4 Pro's weakest category. The airflow control works well but has slight looseness compared to mid-range devices with tighter tolerances. For a budget portable, aluminum construction outlasts the plastic shells that dominate this tier and should hold up to daily pocket carry.
Whether you own the XMax V4 Pro or are still deciding — your thoughts and questions are welcome here.

Every vaporizer we cover is bought, lived with, and tested by the same small team. We log temperatures with an external thermocouple, run battery cycles to depletion, and spend at least two weeks on a device before we score it. No manufacturer has ever paid for, previewed, or influenced a review on this site.
Full convection heater reaches temperature in 25 seconds
The V4 Pro uses full convection heating, passing hot air through your material rather than cooking it against the oven walls. This convection approach produces even extraction across the entire load, preserving terpene detail and preventing the scorching that plagues conduction-only devices at this price.
Heat-up takes 25 seconds to reach your set temperature. The control system spans 100°C to 220°C in 1°C steps, putting precise tuning at your fingertips without needing a companion app.
The 0.25 g oven holds 150% more material than the V3 Pro's 0.1 g chamber, which means fewer repacks during longer sessions. A medium-fine grind packed loosely gives hot air room to circulate through the material, maximizing extraction across the full load.
The 3-position adjustable airflow is the V4 Pro's headline feature. It controls draw resistance from restricted to mid to fully open. Opening the airflow pulls more hot air through the chamber for thicker clouds. Restricting it concentrates the flavor and mimics a tighter cigar-style pull. Community feedback on r/vaporents consistently names this as the single biggest improvement over the predecessor.
The glass and ceramic vapor path keeps flavor clean. Drawing through the borosilicate mouthpiece, you taste herb rather than plastic or electronics. At lower temps around 175°C, expect light, flavorful wisps that let your strain's terpene profile come through clearly. Near the 220°C ceiling, clouds get thicker and more potent with a predictable trade-off in flavor nuance.
The 220°C max temperature is the V4 Pro's biggest performance constraint. Most competitors in this price range reach 230-240°C, which matters if you chase high-temp extraction or want to fully exhaust your AVB. For the 175-210°C sweet spot where most users operate, the V4 Pro delivers vapor quality that outperforms its price class.
Replaceable 18650 battery with USB-C charging
The V4 Pro runs on a standard 18650 cell (2550 mAh included) that delivers around 8 sessions per charge. That covers a full day of moderate use, and carrying a spare 18650 extends your runtime indefinitely. Batteries cost under $10 for a quality cell, are widely available, and swap in seconds by removing the bottom cap.
USB-C charging fills the battery in 75 minutes from empty. There's no pass-through charging, so you'll wait for the charge to complete before resuming. The replaceable design means a dead device is never a problem if you keep a charged spare ready.
For daily users running 3 to 4 sessions, the included cell lasts through the evening. Heavier users grab a spare from the charger and keep going without downtime.
Session and on-demand modes with simple controls
The V4 Pro offers two operating modes. Session mode runs continuously for 4 or 6 minutes depending on your setting. On-demand mode heats for 30 seconds per activation, letting you take a quick hit and pocket the vape without committing to a full session.
Loading is straightforward: remove the glass mouthpiece, fill the 0.25 g oven, and press the cap back on. Dosing capsules make it even cleaner. Pre-load a few before heading out and swap between sessions in seconds with zero mess or sticky fingers.
The glass mouthpiece fits directly into 14 mm water pipe joints without a separate adapter, adding home-session versatility for anyone who wants to run it through glass. Cleaning requires just a quick brush-out of the oven after each session and a deeper isopropyl alcohol soak of the glass mouthpiece every 10 to 15 sessions. Using dosing capsules keeps the oven cleaner and stretches the intervals between deep cleans.
The V4 Pro also handles concentrates using a dosing capsule loaded with a small amount of wax. Set a higher temperature (200-220°C) and draw slowly. It works for occasional concentrate sessions, though a dedicated wax pen will outperform it for regular use.
How It Compares
XMax V4 Pro vs XMax V3 Pro
The XMax V3 Pro defined the budget portable category with full convection and a replaceable 18650 battery. The V4 Pro keeps both of those strengths and adds 3-position adjustable airflow (vs fixed), a 0.25 g oven (vs 0.1 g), a borosilicate glass vapor path (vs zirconia ceramic), a color OLED display, and an on-demand mode alongside session mode.
Both devices share the same battery platform. The upgrade path centers on oven size, airflow control, glass vapor path, and dual-mode operation. For the full spec-by-spec breakdown, see our V4 Pro vs V3 Pro comparison.
For new buyers, the V4 Pro is the clear pick. V3 Pro owners with a working unit can hold off unless the larger oven, adjustable airflow, and glass mouthpiece solve a real frustration.
XMax V4 Pro vs POTV Lobo
The POTV Lobo8.2 is a hybrid portable at higher pricing. It uses a titanium oven with a glass vapor path, a replaceable 18650, and weighs 150 g.
The Lobo's hybrid heating produces denser clouds out of the box with less technique required. The V4 Pro's pure convection preserves more terpene detail at low temperatures and heats faster (25 seconds vs 40). If flavor purity matters most, the V4 Pro edges ahead. For effortless thick vapor with minimal draw technique, the Lobo wins.
XMax V4 Pro vs Fury 3
The Fury 38.4 is a budget hybrid at 159 g. It heats in 20 seconds from a 0.2 g oven and delivers 6 sessions per charge from a non-replaceable built-in battery.
The V4 Pro holds advantages in oven size (0.25 g vs 0.2 g), battery flexibility (swappable 18650 vs sealed cell), and airflow adjustability. The Fury 3 counters with a wider accessory ecosystem including purpose-built glass bubblers that snap directly onto the device and pass-through charging that lets you vape while plugged in.
Who Should Buy This
First-time buyers stepping beyond entry-level get full convection, adjustable airflow, and a glass vapor path at pricing that usually only buys basic conduction. If you're still figuring out what a vaporizer actually does, this is the sweet spot between "cheapest option available" and "serious performance."
Budget-conscious daily users who want reliable sessions without battery anxiety get a replaceable 18650 and a 0.25 g oven. Carry a spare cell and you never run dry.
Portability-first users who prioritize pocketability get 120 g of aluminum with a glass mouthpiece that doubles as a water pipe adapter, covering pocket sessions and home use from the same device.
Final Verdict
The XMax V4 Pro earns VapeExperts' recommendation as a strong-value budget convection portable as of May 2026. It builds meaningfully on the V3 Pro with a larger oven, adjustable airflow, glass vapor path, and on-demand mode while keeping the replaceable 18650 that budget buyers love. The 220°C ceiling is a real limit for high-temp users, but nothing else in this price bracket matches this combination of pure convection, adjustable airflow, and swappable battery flexibility.
