The curly-women has an anti-tangle system to prevent hair to get caught while in use. So if for any reason you took too much hair into the barrel, the system will shut off and immediately release the wick. 

The battery operating time is 60 minutes when used at 180°C

Simply plug your Micro USB cable to the Product and connect it to your laptop, car, or any USB charger.

Don’t worry, the built-in auto-lock system will switch it off automatically after 10 minutes when not in use.
