Not one of the nine air stylers here is cordless, because moving heated air continuously draws more power than a portable cell delivers.
The Beurer Iconic Pro states a brushless 1500 W motor. Dyson states a V9 digital motor at up to 110,000 rpm. Shark publishes no wattage but sits in the same class.
Those are figures a battery of practical size cannot sustain for a styling session.
The only cordless heated tool on this site is the Grundig EasyCurl, a curling barrel rather than an airflow tool, and it states forty minutes of runtime at three temperatures up to 392 °F — the shortest runtime published anywhere on the site.
If cordless is a requirement, that is the family to look at, and the trade is a narrower temperature ceiling than the corded tools reach.
Check your own manual before you follow anything here. Temperatures, water ratings and supply voltages differ from model to model, and the maker’s own figures take precedence over anything written on this site. A supply of the wrong voltage is a failure rather than a slow charge, and the figure is printed on the tool — not inferred from a connector that happens to fit.
