XMAX V4 Pro vs Arizer Solo 3 V2: Budget Convection or Premium Hybrid?
In short: Two of the best portable vaporizers under €150, built on different strengths. The XMAX V4 Pro costs roughly half the price, heats up in 11 seconds with pure convection, and uses standard 18650 batteries. The Arizer Solo 3 V2 counters with a massive 5000 mAh battery, glass stem vapor path, dosing capsules, app control, and a lifetime warranty. The V4 Pro wins on value and flavor purity; the Solo 3 V2 wins on features, battery life, and long-term reliability.

Vapor Quality: Convection Purity vs Glass Stem Consistency
The V4 Pro’s pure convection system excels at terpene extraction. Hot air flows through the herb without touching heated walls, delivering clean, flavorful vapor — especially at lower temperatures around 175–195 °C. First hits are exceptionally tasty, with a light, airy draw resistance. The tradeoff: later draws thin out faster than with hybrid devices, and the chamber needs a stir mid-session to extract evenly.
The Solo 3 V2 uses hybrid heating combined with Arizer’s signature glass stem. Vapor travels through a borosilicate glass tube, adding a layer of flavor purity that no plastic or metal mouthpiece can match. The hybrid system produces thick, consistent vapor from first draw to last. Sessions are longer and more even, but the terpene detail at low temps is slightly less pronounced than the V4 Pro’s pure convection.
Both are excellent — but they excel differently. The V4 Pro wins on Peak flavor in the first few draws. The Solo 3 V2 wins on session consistency and glass-pure taste throughout. If you tend to sip at low temperatures and care about terpene nuance, the V4 Pro has a slight edge. If you prefer set-and-forget sessions where every draw tastes equally good, the Solo 3 V2 is more satisfying.
Battery Life: 18650 Flexibility vs Raw Capacity
This is not close on raw numbers. The Solo 3 V2’s 5000 mAh battery is nearly double the V4 Pro’s 2550 mAh. Expect 12–15 sessions per charge vs 6–7. For home use, both last a full day. For travel or heavy use, the Solo 3 V2 wins outright.
However, the V4 Pro uses standard 18650 cells you can buy anywhere for €5 and swap in seconds. Carry two spares and you effectively have 20+ sessions — more than the Solo 3 V2 on a single charge. The Solo 3 V2’s battery is replaceable too, but uses Arizer’s proprietary cell which costs more and is harder to find.
Both support passthrough charging via USB-C, so you can use either device while plugged in. Charging speed is comparable at around 2–3 hours from empty to full.
Features and Ecosystem
The Solo 3 V2 has a clear feature advantage: app control for custom temperature profiles and session tracking, dosing capsules for mess-free loading (especially useful away from home), and the entire Arizer glass stem ecosystem — short stems for portability, long stems for cooler vapor, and dedicated water pipe adapters.
The V4 Pro has none of these. No app, no dosing capsules, no proprietary accessories. It compensates with universal water pipe compatibility (native 14mm), a straightforward single-button interface, and the simplicity that comes from fewer things that can break. Some users genuinely prefer this “just works” philosophy.
Cleaning and Maintenance
The Solo 3 V2 is easier to maintain in daily use. The glass stem catches most residue — drop it in isopropyl alcohol for 30 minutes and it looks new. The chamber itself stays relatively clean since the herb sits in the stem, not directly in the oven.
The V4 Pro requires more hands-on cleaning. Resin builds up in the chamber and mouthpiece, and the screen needs regular attention. Without dosing capsules, loose herb touches the oven walls directly. Budget 10 minutes per week for a thorough clean with ISO and cotton swabs.
Warranty: 1 Year vs Lifetime
Arizer’s lifetime warranty is the strongest in the portable vaporizer industry. If anything fails due to manufacturing defects, Arizer replaces it — forever. The V4 Pro’s 1-year warranty from XMAX/TopGreen is standard for the budget segment. After 12 months, you are on your own.
For a device you plan to use daily for years, this difference matters. The Solo 3 V2 is essentially a one-time purchase. The V4 Pro may need replacing after 2–3 years of heavy use — though at its price, buying two V4 Pros still costs less than one Solo 3 V2.
Who Should Buy Which?
Choose the V4 Pro if you:
- Want the best flavor per euro spent
- Prefer pure convection extraction
- Like cheap, universal 18650 batteries
- Want a simple device without apps or capsules
- Have a budget under €100
Choose the Solo 3 V2 if you:
- Want glass-stem purity and session consistency
- Need a massive battery for all-day use
- Value app control and dosing capsules
- Want a lifetime warranty from a trusted brand
- Can spend €120–150
Bottom line: The V4 Pro is a remarkable device for its price — it competes with vaporizers twice its cost on flavor alone. The Solo 3 V2 is the more complete package: more features, more battery, more warranty, and the glass stem is genuinely special. If budget allows, the Solo 3 V2 is the better long-term investment. If you want maximum flavor for minimum spend, the V4 Pro is hard to beat.
