CHI, Barbar and Ignis offer cordless flat irons. They are suitable alternatives to regular straighteners while traveling. As with anything, there are pros and cons to each model.
The CHI Escape is identical to its full-size counterpart. However, the temperature cannot be changed. It does include an adapter for charging in the car. Each charge is good for 45 minutes of use.
The Barbar iron comes with a base to recharge the unit. One downside is it only stays hot for 5 minutes at a time before it must be recharged. This is a large flaw for someone who is in a rush.
The Ignis cordless iron only has a heat time of 10 minutes. It can warm up to 400 degrees Fahrenheit. This iron has a small price tag for those on a budget.
There are many options available when searching for battery-powered straighteners. The best product depends on when and why it will be needed.
