AUXO Celsius vs IO Hornet

The biggest practical difference is form factor: these aren't the same kind of device. AUXO Celsius is a portable, IO Hornet is a desktop. Pick based on whether you want something portable or something stationary.

AUXO Celsius reaches session-ready temperature in 6-30 seconds, while the IO Hornet takes 3-5 minutes on a 16mm coil, longer on 20mm and 25mm adapters. That's roughly 222 seconds quicker on the AUXO Celsius, which is useful if you want shorter, on-demand sessions.

AUXO Celsius uses hybrid (primarily conduction) heating, while the IO Hornet uses convection as an injector, hybrid with conduction as a diffuser. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.

AUXO Celsius has the larger chamber at 0.3g dry herbs or 0.05g when using concentrates, versus 0.08g to about 0.2g, around 0.15g for a full draw on the IO Hornet. A bigger bowl means fewer reloads on long sessions; a smaller one suits microdosing and quicker bowls.

AUXO Celsius is the take-anywhere choice. It's a portable, battery-powered unit, while the IO Hornet is built for home use, where bigger heaters, AC power, and larger chambers make sense.

Listed prices are close: $250 for the AUXO Celsius versus $260 for the IO Hornet. Day-to-day price will likely come down to whichever retailer is running a promotion.

AUXO Celsius controls heat with modular - 4 stages (and an app controlled custom mode), while the IO Hornet uses set on a separate pid controller, included only in the complete kit. AUXO Celsius gives you finer per-degree control.
