Cordless Flat Irons Buying Guide

What is a Cordless Flat Iron?

Cordless Flat Iron

We are so used to flat irons or hair straighteners that come with long cords that the term “Cordless Flat Iron” seems a bit new to us; truthfully speaking, a cordless straightener is actually a new concept in the hair styling industry to make your straightening process a lot easier and also more convenient.

As the name suggests, a cordless hair straightening tool doesn’t have any cord attached to it to connect the tool to an electricity line to operate it, instead, this hair straightener comes with either a built-in lithium battery or butane cartridge (which we will discuss in detail below) which helps this styling tool suitable to use anywhere and anytime you want.

Other notable specifications of this type of hair straightening tool are that they are relatively small and lightweight than any other regular flat irons but doesn’t fall behind while styling your tresses as perfectly as a regular one.

The lightweight and smaller size also add to its portability and you can take it anywhere and everywhere to make sure that you can touch-up your straightened manes very quickly whenever needed.

The Types of Cordless Flat Irons

As we have mentioned before, there are two types of cordless flat iron that you will find in the market, and the two types are:

  1. Butane Cartridge Flat Iron
  2. Rechargeable Battery Flat Iron

Now let’s discuss in details about these two types of cordless flat iron for even better understanding and also recommend some of the best cordless flat irons of both these for your hairs.

1. What is a Butane Cartridge Cordless Flat Iron?

Butane Cartridge Cordless Flat Iron

Butane Cartridge flat iron, ThermaCell flat iron or simply gas flat iron, however you call it, is an alternatively powered cordless straightening machine that is installed with a butane cartridge or gas chamber to provide the required energy to the flat iron tool so that you can style your manes precisely without even having to stand near an electric plug point.

The most interesting part of these flat irons is that you don’t have to recharge them with electricity for an uninterrupted styling session. What you have to do is just turn on the straightener by clicking the “on” button and the cartridge filled with butane will start igniting to heat up the plates according to your required heat level so that you can start your hair straightening and styling even where there is no electricity.

Advantages of Butane Cartridge

We have listed more than a few benefits of Butane (gas) Cartridge so that you understand why people from all over the nation are a fan of these flat irons:

  • No charging or recharging required and therefore can be used anywhere and everywhere and any time you wish.
  • One gas cartridge can last for at least 3-6 months depending on the volume of your usage; in this sense, a gas flat iron is very economical as well as super long lasting.
  • Butane refills are largely available in the market (both online and in stores near you) so that it is not very hard for you to find another gas refill for your flat iron once you run out of one.
  • These gas straighteners are very much convenient for camping and trips to remote areas because of their non-reachable nature.

Disadvantages of Butane Cartridge

The few disadvantages of Butane Cartridge that its users should know about before buying a gas flat iron is that:

  • If you are not careful enough, the plates of a gas hair straightener might get as hot as a blow torch and might burn down all your precious tresses. It’s always advisable to pay full attention while styling your manes with a butane flat iron.
  • There are quite a number of restrictions that are applied to butane flat irons when you are traveling by plane. Once the restrictions are fulfilled, there is no problem to carry it with you even during an airplane journey.

2. What is a Rechargeable Battery Flat Iron?

Rechargeable Battery Cordless Flat Iron

Similar to a butane flat iron, a rechargeable battery flat iron is also a cordless hair styling tool that comes with a built-in lithium battery to heat up the plates of the straightener for a flawless styling session. But unlike gas straighteners, you have to recharge the battery on a regular basis with electricity for a certain amount of time to make sure that the straightening tool runs smoothly and effectively while you need it. Regular charging also helps to keep the battery active and in good condition.

Cordless battery flat irons were mainly manufactured keeping in mind about travelers, but because of its vast convenience and extraordinary benefits, people now started them to use on a regular basis.

Advantages of Rechargeable Battery Flat Iron

We have discussed some of the amazing benefits (among many other of its advantages) of battery operated flat irons so that you understand why they are immensely popular:

  • Most of the battery operated flat irons require just 2-3 hours of charging time to get fully charged and a fully charged straightener can be used for at least 30-60 minutes continuously (depending on the battery power and brand), which is enough to style all your manes flawlessly at once.
  • When you switch on a fully charged straightening iron, it only takes a few minutes to heat up the plates so that you can start your straightening and styling session right away, without having to wait.
  • Usually, a rechargeable flat iron is lightweight and compact in size and these qualities also make this styling tool suitable to travel with anywhere you go.

Disadvantages of Rechargeable Battery Flat Iron

Aside from its various benefits rechargeable battery straightening tools also come with some negative aspects, which are:

  • As it claims, a battery operated cordless flat iron is not entirely cordless; you always have to carry a charger to charge the battery in times of need.
  • Furthermore, as these flat irons run with a battery, there is always a chance that the battery might suddenly fail due to charge deficiency and cause severe annoyance.

What to Look for While Choosing a Rechargeable Battery Cordless Flat Iron

We have mentioned quite a few times that the concept of cordless flat irons is relatively new, and hence people don’t know about them as much as they should have known. Therefore, you must keep in mind about some very core aspects (which we have discussed below) while choosing a rechargeable battery hair straightener for yourself to score the best one available in the market.

How Long Does It Operate With a Fully Charged Battery?

We wish that a battery operated flat iron would serve us forever and ever with just one charge!

But in reality, this is not the case. With a fully charged battery, your flat iron would work between 3-6 hours maximum and these too vary upon the battery capacity and the temperature setting you are using while straightening your manes.

For example, we would suggest that while shopping for a battery regulated flat iron, you must at least choose a tool that comes with a minimum of 2600mAh battery because a battery of this power would provide you with at least 30 minutes of continuous hair straightening time when fully charged.

Similarly, a battery with more mAh would give you more operational time with just one charge so that you can enjoy uninterrupted styling sessions anywhere and anytime.

The Time It Takes to Charge Fully

You must also consider the time the battery takes to gain full power while shopping for a battery operated cordless hair straightener; we are saying this because you wouldn’t want to wait for hours and hours just to charge your straightener, especially when you are in a hurry. Furthermore, you also cannot use a battery flat iron when it’s still charging.

But 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 would take to recharge itself.

The Charging Port Type

Cordless flat irons with rechargeable batteries come with mainly two types of charging ports; Pin and USB.

We prefer and also recommend USB charging ports to our readers because you can connect a USB charger to a computer, mobile phone, laptop and even to your car charging system; these means that you can charge your straightening iron almost anywhere you want without having to worry after it runs out of charge.

What About the Construction Material

The construction and coating material of a flat iron plate also plays a vital role in the straightening process as the preciseness of the styling result as well as the health of your precious tresses depends upon it. According to hair experts, you should opt for plates that are made from pure ceramic, ceramic tourmaline, titanium ceramic, Nano Ceramic because these materials are suitable for all types of hair (be it fine/thin or thick) and can guarantee you that your straightening results will be perfect without causing any burns, hot spots or damages to your hairs.

The reason hair specialists recommended these plate materials is that they can generate just the right amount of heat, spread the heat evenly throughout the hairs and can style your tresses precisely without exposing them to any danger.

One important piece of information we would like to mention is that, as cordless hair straightener is a relatively newer product in the market, manufacturers don’t produce and offer a wide variety of plate materials to their customers to choose from according to their particular hair type and hence, materials that are suitable for all types of hair are the best choice for you.

Remember the Heat Settings

As in this article, we are recommending cordless flat irons for all types of hair out there; we would suggest that you choose a straightener that comes with multiple heat settings (between 200° F to 450° F) so that you can regulate the temperature according to your hair’s requirement.

Top Cordless Flat Irons

Our Recommended Best Butane Cartridge (Gas) Cordless Flat Iron

Manufacturers have not yet warmed up about the idea of Butane Cartridge (Gas) hair straighteners and therefore, there are not many gas straightening irons available in the market. And as there are very few butane hair styling tools available, it was quite easy for us to pick the best one for you.

Conair Mini Pro Cordless Ceramic Flat Iron

Conair Mini Pro Cordless Ceramic Flat Iron

Ranking Position: 1
Our Opinion: Provides Total Freedom of Usage

This Mini PRO from Conair is our best and only choice for cordless butane flat iron because the concept of gas operated hair straightener is relatively new and there are only a few of them from different manufacturers are available in the market.

The reasons it is our only choice are because:

Conair ensured total independence of its users with this flat iron; we are saying this because powered by a ThermaCELL® butane cartridge, this hair straightener not only helps you to get rid of any cord, adopter and electrical outlets, but at the same time makes sure that you can get the best styling results even without the use of any electricity. It uses its ThermaCELL® butane cartridge as a source of fuel to heat up the flat iron plates with your required amount of heat and straighten your manes anywhere and everywhere you wish; from your own vanity to the gym and pool and even when you are camping, this flat iron would never fail to keep you stylish.

Now the question arises what you would do if the butane gas runs out and the straightener no longer works? Well, you can buy the Conair ThermaCELL Refill Cartridges and refill your tool with one so that it runs as smoothly as it did before.

Moving on, keeping in mind about all types of tresses, Conair constructed and coated the plates of this straightener with pure ceramic because ceramic tends to absorb just the right amount of heat (the temperature reaches up to 419°F) to straighten all types of hair without causing any hot spots and breakage in them. Other than just straightening and touch-ups, you can also create versatile curls and waves effortlessly as floating plates of this tool have beveled edges and don’t break your strands when you twist them.

Another feature that helps to keep your tresses healthy as well as protected from heat damage is the ionic technology incorporated by Conair in this flat iron. This technology uses an ionic generator to release plenty of negative ions that lock in hair moisture to not only keep them frizz-free, smooth and healthy but at the same time also forms a protective layer to save your tresses from burns and damages,

Few Additional Features

  • The ergonomically designed handles ensure firm yet comfortable grip for safety
  • At just 8.3 ounces, this flat iron is super lightweight and hence incredibly portable
  • Can also be used internationally
  • The plates heat up in just 2 minutes to start styling immediately

Furthermore, with its USB  charging port, you can recharge this battery by a power bank, laptop, your cell phone, and other USB-compatible sources.

But then again, if you don’t have any USB-compatible sources near you and you have to charge your flat iron, you can always use a plug adopter like this HopePow USB Wall Charger Plug and charge the tool with direct electricity.

Deogra Cordless Mini Flat Iron

This fuchsia pink, eye-catching Mini Flat Iron from Deogra is another of our favorite cordless rechargeable battery straightening tool to straighten and styles all types of hairs; we are stating this because this tool offers more than a few outstanding features and aspects that are sure to blow your mind.

Let’s start with its 2600mAh battery and the charging time; the built-in lithium-ion battery of this straightening iron takes just 1.5 hours to get fully charged which is quite extraordinary as a battery of such power takes more than 2 hours for full charging. Also, with a fully charged battery, you are able to use this flat iron for 30 minutes (continuously) within which time you can straighten, curls, flip or just touch up the existing style in your vanity or anywhere you wish.

The word “anywhere” reminds us that with just 9.80 ounces of weight and 7.8 inches of length, this cordless straightening iron is super portable and can be carried inside a purse or even in your pocket so that you can keep yourself styling and ready whenever you want. Moreover, such lightweight also ensures that your hand don’t hurt

Reasons for Not Choosing

Rêve Next-generation Cordless Hair Straightener

This RÊVE is one sleek, polished good looking hair straightener that has good 80 minutes operational time. But it still didn’t spot a place in our best list because of its other not so great features.

  • Firstly, the manufacturer didn’t incorporate the ionic technology in this straightening tool which is a must-have feature for all types of hair to keep them hydrated, nourished and frizz-free. Instead, it only comes with infrared emission technology which is just an optional feature.
  • To add more, RÊVE constructed the plates of this flat iron with titanium material which is an excellent component for thick hairs but is not at all suitable for fine/thin hairs.
  • Also, the pin charger of this expensive straightening tool is not the best one because you can only charge the battery using a plug point and not using your phone or laptop as a USB charging port.

Our Final Thoughts

Even though cordless flat iron is a relatively new product in the market, there is no denying that it made our styling needs easier and more convenient. The products we have suggested above would prove our claims because they not only give you the freedom of movement and portability but at the same time also offers some other amazing features to straighten your manes perfectly without causing any hot spots, damages, and hair falls.
