ghd Unplugged Styler 1" Cordless Flat Iron Hair Straightener - Professional Travel Hair Straightener with Heat-Resistant Case & USB-C Charging (20 Min Runtime) - Perfect for On-the-Go Styling, Travel & Touch-Ups

I was really concerned that the battery charge wouldn’t last long enough to do my hair but it does. I bought this for an international trip so I wanted something lighter weight and the usb charger made it a no brainer. I have medium length hair and this worked faster and better than my plug in straightener at home. It’s expensive but for me it is worth it.
