Mighty+ USB-C Supercharge vs Pax Flow, Venty & Solo III – Charging Speed Showdown

Admin August 13, 2025 1 min read

This is a spec-only comparison—no user reviews or hands-on experience—just hard numbers on charging speed, battery, and runtime.

What’s Changed with the Mighty+

Storz & Bickel’s Mighty+ now supports USB-C Supercharging, achieving 80% battery in about 40 minutes when using their 15 V @ 3 A “Supercharger” Without it, charging is notably slower.

Charging Speed Comparison Table

DeviceCharge to 80%Full Charge TimeNotes
Mighty+ USB‑C Supercharge~40 min (using 15V@3A charger)~40 min (using 15V@3A charger)Only with official supercharger
Pax Flow~20 min to 50%, ~40 min full~40 minFast USB-C charging option; optional charging stand available
Venty~40 min to 80%, <60 min full with Supercharger<60 minWith same USB-C adapter as Mighty+
Solo III~2.5 hours to 80% via USB-C~3 hoursSupports use-while-charging but charges slow

Battery Capacity & Runtime Context

  • Solo III: Delivers up to 3 hours of session mode use or 100+ on-demand draws, with ability to use while charging 

  • Pax Flow: Offers ~4–6 sessions per charge, roughly 35 minutes runtime, with 50% recharge in ~20 minutes 

  • Venty: With dual internal 18650 batteries, it can deliver ~12 full bowls (~3 g total) per charge, thanks in part to larger capacity and efficient design 

  • Mighty+: Known to support extended sessions with pass‑through charging, making longer use possible even while recharging

It seems like Solo III wins the longevity award, easily.

Portability & Charging Convenience

  • Mighty+ & Venty: Require the proprietary “Supercharger” (or equivalent 15 V@3 A USB-C) for fast charge—some limitation due to special power requirements 

  • Pax Flow: Uses standard USB‑C; quick 40-minute full charge plus optional magnetic desktop stand adds convenience 

  • Solo III: Also USB‑C, but charging takes ~3 hours, though you can use the device while charging, which softens the long charging time impact

Final Word: Who Charges Fastest Today?

  • Fastest Charging (to >80%): Mighty+ (with Supercharger) and Venty both hit ~80% in ~40 minutes.

  • Best Balance of Speed & Convenience: Pax Flow matches those times (40 min full, 20 min half) using standard USB-C—no special adapter needed.

  • Longest Runtime, Slowest Charger: Solo III takes ~3 hours to charge, but its massive ~3-hour session runtime and ability to use while charging make it a practical choice for heavy users.
