Dyson Airstrait. After I rough dry my hair halfway with the Supersonic Nural, I use this innovative wet-to-dry straightener to dry and smooth the rest of the way — no hot plates needed.

It’s a portable charge cord with 120-volt (1.4 kW) ... What that means is that you can plug it into a regular, 3-prong household outlet or in a 4-prong “dryer” outlet for faster charging.
