Short answer: The old comparison of ‘hybrid versus convection’ was incorrect. The ÄRiS Ultra manual specifies convection; the current FENIX Pro product page specifies ECA convection. The ÄRiS Ultra offers the wider range of 100–220 °C and a five-year warranty, while the FENIX Pro offers 160–221 °C and a 3–6-minute timer.

Heating method without marketing shorthand
For the ÄRiS Ultra, the manual is unambiguous: convection. For the FENIX Pro, the current product page specifies ECA convection; however, an older manufacturer blog post from 2020 classified the model as hybrid. For the current comparison, we follow the specific product page and document the historical contradiction instead of presenting ‘pure convection’ as an undisputed fact.
Size and everyday use
Without its mouthpiece, the FENIX Pro is shorter at 84 mm than the 101.25 mm-tall ÄRiS Ultra; their widths and depths, by contrast, are similar. That alone proves neither better pocketability nor a lower weight, as the current FENIX product page does not provide a verifiable weight figure. For the Ultra, a weight of 133 g and operation while charging are documented. We make no equivalent claims for the FENIX Pro unless the manufacturer’s source confirms these points.
The almost identical heat-up time of around 25 seconds also says nothing about vapor production or battery life. The desired temperature range, timer range, warranty terms and actual available price are therefore more important to the decision than declaring an overall winner.
Which device is the better fit?
- ÄRiS Ultra: if a minimum temperature of 100 °C, documented weight, pass-through charging or a five-year warranty matter.
- FENIX Pro: if 160–221 °C is sufficient and the current offer is cheaper.
- For both: check prices, included accessories and warranty terms with the specific retailer; do not invent an app or your own side-by-side measurements.
Current offers: ÄRiS Ultra from 139.00 € incl. shipping at 60 retailers; FENIX Pro from 135.00 € incl. shipping at 25 retailers.
