Best Cordless Curling Irons of 2020 – Ultimate Review

| Last Updated: January 21, 2022

Cordless curling irons are a wonderful technology. Curling irons with cords can be so limiting as they restrict the distance you can be away from a mirror, while also preventing you from using them in a place with no plug.

Moreover, those who want to travel with their curling iron don’t have to worry about adapter plugs or dual voltage, as a cordless curling iron works without direct access to electricity. That said, it is important to consider the different options available to you.

Cordless curling irons are typically powered with either butane or rechargeable batteries. Each option comes with its advantages and disadvantages so make sure you consider your lifestyle patterns when making the choice.

Benefits of a Cordless Curling Irons

Cordless curling irons can be such a bonus. You’ll find that, usually, curling irons are limited by the length of their cord. A cordless curling iron doesn’t have these limitations, meaning that you don’t have to reposition your mirror near a plug. This can be especially true for people who only have a mirror in the bathroom, where you’ll rarely find a mains electricity socket.

What’s more, even though most curling irons feature a rotating cord, you will find that often this cord still gets twisted while you work. Cordless irons are free from this issue.

For those who travel a lot, you will need to have dual voltage capabilities for your curling iron if it requires mains electricity. Moreover, you’ll usually need to purchase an extra plug adapter. Not only is this an extra cost, but it can be bulky in your suitcase. A cordless curling iron doesn’t require either of those things, making it a far better travel companion. This is especially true of cordless curling irons that recharge using USB chargers as they are the most adaptable tools to reload.

Cordless curling irons tend to be smaller than regular curling irons. This is a great advantage for travelers and people with shorter hair. This also makes them lightweight, which prevents your arms from aching, and makes them easy to pack in your suitcase.

Butane vs. Batteries

Butane curling irons work with a small cartridge of butane. The butane gas burns, which heats up the curler. When this cartridge runs out, you replace it with a new one. These curling irons are usually quite compact, making them great to pack in your suitcase.

However, they tend to get quite hot and it can be expensive to continuously replace their cartridges. Moreover, the correct cartridges can be hard to find abroad, and if the company stops making that model, you may not be able to find them at all.

It is also important to consider the way in which you travel. For some people who only carry hand luggage, a mini cordless curler seems like a great option. However, many butane curlers cannot be carried in hand luggage, with the same going for the spare cartridges. Bear this in mind or you may lose them when you check in at the airport.

Battery powered curlers are usually rechargeable. This means that you don’t have to keep paying for cartridges. Some come with USB chargers, whereas others come with mains chargers. They tend to last between 30-50 minutes on a single charge, which is enough time to curl your hair twice. USB chargers are more versatile as they can be charged abroad, whereas the problem with mains chargers is that you will need to have dual voltage and an adapter if traveling.

Make sure to consider how long the curler takes to charge and how long it holds charge. If you have long or thick hair, you will need a battery-powered curler that lasts for a longer time between charges. Unfortunately, many battery-operated curling irons only last for 20 minutes before they need to be charged again. In some cases, they may take a long time to recharge.

Drawbacks of a Cordless Curling Iron

Cordless curling irons come with their own drawbacks. They tend to be smaller in size than regular curling irons. While this may be a bonus for traveling, it can make them difficult to use with long or thick hair.

In addition, you’ll find that as battery-powered curling irons run out of battery, their heat decreases dramatically. You may not notice at first, which will cause some of your curls to drop out more quickly than others throughout the day. When they do run out, you have to wait for them to recharge. If you forget to recharge it, you may have to wait up to 30 minutes before you can curl your hair.

As noted above, those with thick and long hair may want to pay special attention to how long these curling irons hold charge for, as some of them barely hold charge for longer than 20 minutes. This will dramatically increase the time it takes to curl your hair, as you’ll have to recharge halfway through.

Butane curlers can be an issue for those traveling. As noted above, the cartridges can be hard to come by. As butane curlers are less common than electric curlers, cartridges may be inconvenient or expensive to replace. Replenishing the cartridges represents an ongoing cost, unlike regular curlers that have a one-time cost when you buy them (though in your home you pay for your electricity). Not only is this an added cost to your life, it is not very environmentally friendly as the cartridges cannot be recycled.

  • Only stays hot for 20 minutes at a time before needing to be recharged; this can be an issue if you have lots of hair as you’d have to wait for a recharge halfway through.

This curling iron has a ceramic barrel and features three heat settings. It is lightweight and stays hot for about 20 minutes in between charges. The barrel is roughly an inch wide and it features dual voltage.


Cordless curling irons are a great choice for people who are tired of getting themselves wrapped up in the cord or need to have more flexibility with the location where they curl their hair. Try to think about your lifestyle when choosing which one suits you best. If you are on a constant budget, try to find something that recharges rather than a butane cartridge curler.

This is equally true for people who have an affinity to environmentally-friendly products, as the butane itself is bad for the environment, coupled with the waste from the cartridges. That said, try to find a rechargeable product that stays hot long enough that you don’t need to keep recharging it, or this can be a pain to work with and just as bad for the environment.
