This cordless straightener is ideal for use at dog shows or when you don't have a power outlet to your disposal. It features heated Teflon plates with 3 temperature settings. It's powered by a lithium-ion battery which will last up to 60 minutes depending on the chosen temperature setting. The hair straightener heats up quickly and the indicator light stops flashing to signal ready-for-use. There's a battery saving auto-shut-off when no activity is detected.
