Arizer Solo 3 vs Mighty+ Review Comparison: Glass Stems vs Cooling Unit & Airflow

The Arizer Solo 3 and the Storz & Bickel Mighty+ are two of the most popular premium portable vaporizers in 2025. Both promise excellent vapor quality, but they take very different approaches: the Solo 3 with its modular glass stem system and the Mighty+ with its famous built-in cooling unit. In this comparison, we’ll break down battery life, airflow, consistency, and overall performance to help you decide which is best for your vaping style.

Design & Build Quality

Arizer Solo 3: Solidly built with a brushed metal chassis, the Solo 3 keeps the traditional Arizer design but adds a modern interface and USB-C charging. Its reliance on glass stems means you’ll need to handle it with care, especially when traveling.

Mighty+: The Mighty+ is rugged, plastic-bodied, and designed for portability without fragile glass. Its cooling unit doubles as the mouthpiece and is replaceable, making it durable and easy to maintain.

Heating & Vapor Path

Solo 3: Uses a hybrid conduction/convection oven paired with interchangeable glass stems. The all-glass vapor path is a huge selling point for flavor purists, and with XL or frosted WPA stems, you can customize your session length and cooling style.

Mighty+: Also hybrid, but its strength is consistency. The integrated cooling unit ensures vapor is always smooth and comfortable, even at higher temperatures. No glass required, but also less flexibility for customization.

Battery Life & Charging

Solo 3: A major advantage—expect around three hours of continuous use in Session Mode, plus USB-C charging with passthrough support. Perfect for long trips or group use.

Mighty+: Delivers solid battery performance with around 8–12 sessions per charge depending on temperature. It features USB-C fast charging and optional “Supercharge” with a 15V/3A adapter, bringing it to ~80% in 40 minutes.

Airflow & Draw Resistance

Solo 3: Standard stems can feel restrictive, though Arizer’s new high-airflow and XL stems improve this significantly. When paired with water adapters, airflow becomes much freer and the vapor noticeably smoother.

Mighty+: Famous for its low draw resistance. The cooling unit and wide airpath make inhalation effortless, which is why many consider it the most approachable high-end portable on the market.

Session Style & Consistency

Solo 3: Offers both Session Mode (sit back and vape continuously) and On-Demand Mode (quick hits on the go). Extraction is thorough, but the experience varies depending on which stem you choose.

Mighty+: Delivers consistent results every time—no stirring required, no stem swapping. Vapor production is predictable, making it ideal if you want reliability above all else.

Cleaning & Maintenance

Solo 3: Cleaning is easy: glass stems soak in isopropyl alcohol, and the oven just needs a brush. However, you’ll need to keep multiple stems clean if you rotate them regularly.

Mighty+: Requires regular cleaning of the cooling unit to prevent buildup. Fewer removable parts than the Solo 3, but the cooling unit itself takes a little more effort to deep clean.

Head-to-Head Comparison

Feature	Arizer Solo 3	Mighty+
Vapor Path	All-glass stems (customizable)	Built-in cooling unit (fixed)
Battery Life	~3 hours continuous	8–12 sessions, fast charging
Airflow	Restricted on stock stems, better with XL/High Airflow	Low resistance, smooth draws
Session Styles	Session & On-Demand	Session only, very consistent
Portability	Durable but glass makes travel tricky	Rugged and travel-ready
Customization	High (swap stems, WPAs, XL options)	Low (designed for simplicity)

Which One Should You Buy?

Choose the Arizer Solo 3 if you want:

• Flavor purity: The glass stem system delivers unmatched taste.
• Custom sessions: XL, angled, and WPA stems give flexibility.
• Battery stamina: Three hours of use makes it a marathon performer.

Choose the Mighty+ if you want:

• Effortless airflow: Smooth, unrestricted draws every time.
• Consistency: Predictable performance without stirring or swapping.
• Travel durability: A rugged design without fragile glass.

Final Thoughts

Both vaporizers are outstanding—but they suit different types of users. The Arizer Solo 3 is for those who value flavor, battery life, and customization through glass accessories. The Mighty+ is for those who want reliable, consistent, and hassle-free performance with minimal setup. Ultimately, your choice depends on whether you prefer to tinker and tailor your sessions (Solo 3) or just press power and enjoy (Mighty+).
