Best Cordless Flat Irons Reviewed

Lanxim Cordless Mini Flat Iron

Lanxim Cordless Mini Flat Iron
  • Tourmaline Ceramic Floating Plates
  • Rechargeable 5000mAh Lithium Battery
  • 3 Heat Settings - 327°F, 365°F, 401°F
  • Battery Indicator + Hinge Lock
  • USB Charging Port + Cable

Size: 8.46″ x 1.85″ x 1.85″
Weight: 0.5 lbs.

The Lanxim Cordless Mini Flat Iron is a battery-operated straightener featuring 3D floating plates that flex from side to side while you press for a firm grip and evenly straightened tresses. The edges are curved, so it can double as a curler too.

The tourmaline ceramic plates help eliminate static, reduce frizz and protect from heat damage.

There are a choice of three temperature settings – 327°F, 365°F, and 401°F – so you can control the heat. You can also see how much power you have left with markings for 100%, 75%, and 50% battery levels that light up just below the temperature setting.

I do wish the heat and power level settings were easier to see – the digits are kind of small.

In any case, it heats up super quick – within five to 15 seconds after you turn on – and it even has a memory function that will automatically set the temperature to the last one you used. 

The 5000mAh lithium battery lasts up to 80 minutes on a full charge, which may vary depending on how much you use it. It’s recommended to recharge it after each use so you don’t run out of juice midway through your next use. 

Lastly, it comes with a USB charging cable only, which means you’ll need to get a USB power adapter if you want to plug it directly into an outlet. Otherwise, you can charge it via a connected laptop, or any 5V USB device like a smartphone or car charger.

  • Floating plates ensure a secure grip
  • Lightweight and fits in the palm of your hand
  • Battery level indicator shows how much charge you have left
  • 3 Temperature Settings
  • Heats up in 15 seconds
  • Doesn’t come with an outlet adapter, only a USB cable
  • Temperature and power level settings are small and hard to read

Deogra Cordless Mini Flat Iron

Deogra Cordless Mini Flat Iron
  • Tourmaline Ceramic Floating Plates
  • 1 Heat Setting - 392°F
  • Rechargeable 2600mAh Battery
  • Micro USB Charging Port + Cable
  • Fully Charges in 90 min

Size: 1.6” x 1.1” x 11.2”
Weight: 0.62lbs

The Deogra Cordless Mini Flat Iron is some serious eye candy. It’s a compact little number with shiny mermaid colors that fits easily in your purse or handbag for touch ups at the office, on the road, or at the gym.

It works on a 2600mAh rechargeable battery and comes with a micro USB cord. Your best bet is to pair it with an iPad charger for fastest charging.

According to the manufacturer, the battery takes 90 minutes to fully charge for about 25 minutes of use time, but in truth it doesn’t last more than 20 minutes at most (if even that long).

So, just know that this is really only useful for minor touch ups for bangs, flyaways, and taming ends that stick out.

The floating tourmaline ceramic plates get up to 392°F (the only setting), and the heat up time is about 3 minutes – kind of a long time for a little thing! If you have finer locks, you can even make a few curls with it.

Overall, this is a cute little tool, but it doesn’t get hot enough to do much if you have thick, curly, or coarse hair.

  • Lipstick-design with cap
  • Compact size fits in your purse
  • Drawstring velvet carry bag included
  • Great on little kids
  • Charging indicator light
  • Only one heat setting
  • Short usage time

Travel Smart by Conair Thermacell Ceramic Straightener

Travel Smart by Conair Thermacell Ceramic Straightener
  • Cordless Butane Gas-Fueled Flat Iron
  • Max Temperature - 419°F
  • Ceramic Plate Technology
  • 1 ThermaCELL Cartridge Included

Size: 11.2″ x 4.4″ x 1.8″
Weight: 0.5 lbs.

If you don’t want to worry about recharging at all, then the Travel Smart by Conair Thermacell Ceramic Straightener might be for you. It’s powered by a Thermacell butane cartridge and gets quite hot for a cordless straightener – up to 419°F.

For you jetsetters out there, yes, a butane fuel cell is approved to go in carry-on luggage on an airplane as long as it’s attached to the iron.

While you don’t have to recharge the unit the way you do with a battery-operated one, it does require replacing the butane cartridge whenever it runs out of fuel. They’re readily available and easy to purchase though.

Since it runs on fuel, it works like a lighter in that you have to ignite the fuel cell inside to get it powered up. If you need a higher temperature setting, let it heat up longer before using or you may not have enough power to straighten and style.

It’s most useful for light touch ups when camping or glamping, or any other far-from-civilization activity where you won’t have access to an electrical outlet.

Like most cordless straighteners, don’t expect it to be powerful enough to straighten a whole head of thick hair. If you use it for taming bangs and frizz or have short, fine hair, it’s a good choice.

  • No need to recharge with electricity
  • Gas cartridge outlasts battery flat irons during single sessions
  • Good for camping and outdoor activities
  • Lightweight and easy to pack
  • No temperature control
  • Must purchase additional cartridges for continued use

Benefits of a Cordless Flat Iron


Of course, the best thing about a wireless flat iron is the fact that you’re not tied to the nearest power outlet.

Just be sure that it’s fully charged before you take it somewhere, and recharge it between straightening sessions if you use it for more than a few minutes at a time.

USB Rechargeable

Most cordless flat irons are rechargeable via USB or mini-USB cables, which means you can connect it to your laptop, car charger, or wall USB port.

Great for Bangs and Touch-Ups

Going on a date or stuck in humid weather? You can easily touch up bangs in the car or tame frizz in a jiffy with a cordless straightener. 

Compact and Easy To Maneuver

A cordless flat iron gives you complete freedom to hold and maneuver any which way without a cord getting in your way. 

It’s hard enough getting the right hand-eye coordination when you have to switch from one side of your head to the other!

Also, cordless straighteners tend to be smaller. They’re compact and lightweight so that you can squeeze them into purses, carry-ons, or daybags. 

Look Good While Traveling Or In The Great Outdoors

If you like hiking and camping, you might think your hairstyle would be the least of your concerns. Well, thanks to portable flat irons, you don’t have to choose between mother nature and looking good. You can have both!

Similarly, if you’re a frequent traveler, you can make sure everyday is a good hair day regardless of how long you’re spending on the road.

Things to Consider Before Buying a Cordless Flat Iron

Your Hair Type and Use Case

Be realistic: if you’ve got a thick head of coarse, curly hair, this is not going to be the tool for you. There isn’t enough power or charge to straighten unruly locks, so don’t waste your time with a cordless. 

Plates are usually narrower and shorter, making it necessary to use smaller sections of hair for effective results.

Cordless straighteners are best for on-the-go touch ups on shorter, finer hair, and works great on bangs. They’re also great at smoothing ends or curling them under so they don’t stick out every which way.

Power Type

Cordless flat irons are powered in two ways: rechargeable battery or butane cartridge. The vast majority are battery-operated, which you have to plug into an electrical outlet or other connected device to recharge.

Butane is a type of fuel in the form of a gas that gets ignited (yes, really), providing power to heat your appliance. Instead of recharging the iron, you simply replace the butane cartridge once it’s depleted.

Generally speaking, you’re best served with a battery-operated one because you’ll have more options to choose from. Plus, you won’t be as limited by specific TSA packing regulations if you fly with one.

Airline Regulations

You can pack a battery-operated flat iron in either carry-on or checked luggage as long as the battery is inside the appliance itself.

However, butane cartridge flat irons must be packed in carry-on baggage only. You cannot bring a spare cartridge in your luggage separately, either.

Dual-Voltage Compatibility

You may want a dual-voltage straightener if you travel internationally. Do note that you’ll usually need to buy a separate power adapter since most battery-operated flat irons come with a USB cable only. 

The standard power outlet in the U.S. is 110-120 volts. In Europe and throughout Asia, it usually ranges from 220-240 volts.

Straightening on the Go

If you travel to remote places or just to the next town over, a cordless flat iron will become your best friend. It’s a compact and convenient beauty appliance, which is what you need when you’re on the go.

The best of the bunch in my opinion is the Lanxim Cordless Mini Flat Iron. The floating ceramic plates make for a smooth styling process and it only takes 15 seconds to heat up. It’s a veritable frizz-be-gone device.

It’s got the most powerful battery to keep you styling longer, plus you can create curls or flips with it too.

Now get out there and rock those locks no matter where you are!
