Cordless Flat Iron Buying Guide

What Is A Cordless Flat Iron?

Ever wrapped yourself in your flat iron cord? Then you probably can grasp the concept of styling your hands without annoying cords around.

A cordless flat iron is simply the styling device you already know minus the cord. Since these appliances do not come with a cord they straighten hair through the use of a battery that is USB rechargeable.

This means that not only can you use them anywhere in your home, but you can take them on the go to touch up your hair at an event or fully style it on your lunch break. The possibilities are endless.

How Does A Cordless Flat Iron Work?

Flat irons in general, work by breaking down the positive hydrogen bonds found in the hair’s cortex, which causes hair to open, bend and become curly.

A battery-operated or cordless flat iron comes with a removable lithium battery that needs to be charged to enable the appliance to work. Some models include a wall charger, but most new cordless straighteners can be charged with a USB cable plugged into a wall adapter, laptop, or iPhone.

And the best part? Because cordless flat irons hold a charge, they eventually die, which means you never have to worry if you remembered to turn off your straightener before leaving the house, because after a while it will inevitably happen on its own.

Features To Look For In A Cordless Flat Iron

Heat Settings

It is always best to choose a wireless flat iron that has multiple heat setting options. This is very useful as you can operate the straightener according to your hair’s requirements and even change the heat setting as per your convenience. Another thing that is helpful is a display light that shows you the temperature that you have selected.

Plate Size

If you want to use your straighteners for curling as well as smoothing the hair, it’s important to consider the size of the irons – larger plates will give loose waves, whilst narrower ones will give tighter curls.

Charging Port Type

Cordless flat irons with rechargeable batteries come with mainly two kinds of charging ports – pin or USB. The USB charging port is definitely recommended because you can connect it practically anywhere –your laptop, computer, or even your car’s charging system. It is the most convenient charging method.

Charging Time

You must always consider the total amount of time it takes to fully charge the battery of a cordless hair straightener. This is because you cannot use your cordless flat iron while it is charging. It is also not viable to wait for hours and hours for the battery to charge fully.

But, you must always remember that the time a battery needs to gain full power is directly related to its mAh – the more powerful a battery is, the more time it takes to charge. However, this also means that it will last longer per charge.


This one is a no-brainer. It is obvious that a cordless hair straightener is perfect for traveling or simply carrying around in your purse if you are someone who requires frequent touch-ups. So, a lightweight cordless hair straightener is what you must look for.

Battery Type

  • Butane Cartridge Flat Iron: The butane cordless flat iron cartridge or gas chamber that is present in the flat iron provides the required energy for it to heat up. The most convenient thing about these cordless hair straighteners is that you don’t have to charge them with electricity for an uninterrupted styling session. These butane cartridges can last up to three to six months before they need to be replaced.
  • Rechargeable Battery Flat Iron: This type of cordless flat iron comes with a built-in lithium battery that needs to be recharged with electricity on a fairly regular basis to make sure that the straightener does not abruptly run out of battery and stop working. But, they do run for a fairly good amount of time when charged completely.

Plate Material

  • Ceramic: It evenly distributes heat throughout the plates and is considered to be safe as it cannot burn hair easily.
  • Titanium: These plates heat up faster, so they can prolong the battery life of your cordless straightener. But if they are on your hair for too long, they are likely to cause heat damage.
  • Tourmaline: Tourmaline is a crystalline mineral that is crushed up and coated over flat iron plates. This substance is said to make your hair shinier and reduce frizz significantly.
