USB charger and then runs on charge. Great for travel.
Soooo cool! Totally works better then expected. I do have very long hair about 20” and I had to press the run button 2-3x to get the level of curl I wanted.  It stayed 2 days and would have stayed longer if I didn’t wash my hair.  A little bit of  a learning curve so maybe practice before an event. But the coolest part was I brought it in my purse so I could finish doing my hair in the car while my husband drove.  Great time saver!
