What is a 12V Hair Straightener?
As the name itself speaks, a 12V Hair Straightener is simply a hair straightener that can be plugged into the 12V power outlet or car cigarette lighter to power up. These straighteners are specifically designed to give you the freedom to style while sitting in your car.
Most of the cars, trucks, SUVs, caravans, and pretty much all other vehicles nowadays come with an auxiliary 12V power outlet or cigarette lighter outlet. These sockets also allow you to use flat irons in your car.
However, flat irons that plug into cars are low-powered. They come with 15 – 25 watt power input that uses up to 200 watts from your car battery. Hence, the tool cannot be used for heavy usage, though it works amazingly for instant touch-ups before a party or important meeting or while camping.
The portable flat iron for the car is not recommended for professional use as they are 12v irons. You can use this hair styling tool whenever you feel the need to give your hair a quick fix during office hours, before a party, or any other situation where you want to look your best.
The flat irons can give you a frizz-free, glossier look within minutes. All you have to do is plug it in your car and start styling. Plus, while the flat irons suit all hair types, these irons work best for short-haired girls.
In-Car Hair Straightener – Buying Guide
There are several aspects to consider before purchasing a hair straightener for the car. You need to check the plate material, size, length of cord, power input, etc. to ensure that the straightener is the right fit for your purpose.
Powers from 12V Auxiliary Power Outlet/ Cigarette Lighter Outlet
The 12V hair straightener starts heating as soon as you power it up using the auxiliary power outlet in your car. It is basically, a DC-powered flat iron that can be powered through most of the latest vehicles.
Alternatively, these flat irons can also be powered using the regular AC connection. However, this is only possible using voltage converters.
Measurement of Plugs
12V flat irons have way different plugs than regular ones. The plugs are round in shape that can fit in your car’s power outlet. The diameter of these plugs also varies in certain countries. Generally, the plugs of most car hair straighteners have a diameter of 20.73 mm to 21.18 mm.
Though it is highly suggested to purchase a hair straightener that has a plug with bigger diameters as this makes it usable in older car models. Plus, it also works in most of the European and Asian vehicles available outside the USA.
No matter in what corner of the world you live in, you’d want to pick the flat iron with 21.88 mm diameter, to get the freedom of styling while traveling in any country.
PTC (Positive Temperature Coefficient) Heaters are the best ones when it comes to hair styling tools. These tools last for a longer time and are safe to use.
Irons with PTC heaters cool down quickly, preventing them from getting overheated. Even when you leave them on for a longer time they won’t get overheated.
Contrarily, certain 12V flat irons come with MCH technology, that heat up quickly. But they also consume high battery power and get overheated quickly. So, it’s better to avoid such car hair straighteners.
While buying a 12V car flat iron, it’s good to go for the one that has PTC heaters. This will consume less power and not drain the car battery much.
Low Power Input
A necessary feature that every car hair straightener should possess is the ability to use low input voltage.
The regular flat irons usually run on 45 – 70 watts inputs which are quite less as compared to 12V hair straighteners running on 15 – 28 watts.
The regular flat irons when used in cars, can consume up to 1000 watts of battery power, whereas a car straightener will only take up 150 watts.
There are plenty of car straighteners that you can choose from. But it’s advisable to purchase one with 18 – 24 watts consumption. This will not be heavy on your car battery yet do a great job for you.
Additionally, these flat irons will also heat up perfectly to give your tresses a smooth look.
A fuse is an electrical safety device that saves the circuit from overcurrent. Car straighteners should have a built-in fuse to prevent the occurrence of excessive current flow.
Since flat irons are manufactured for infrequent use, their components are delicate. This may cause current flow, which in turn may damage both, the car’s power system and the flat iron.
With a built-in fuse, you no longer need to worry about such electrical hazards. Therefore, it’s essential to have a built-in fuse in the plug of a car straightener.
Being specifically designed for use in cars, a car flat iron has a much shorter cord. Ideally, the cord length of most car straighteners is between 3.5 – 4.5 feet, which is nearly half of regular ones.
Straighteners with a cord length of 4 feet and above are highly recommended, as they make it easy to style all parts of your hair.
Adjustable Twist Locks for Plugs
Hate it when the plug slips out while styling your hair? No worries, get a flat iron with twist locks for plugs. This lock will ensure that the plug remains in the socket, till you complete your styling.
Further, the adjustable lock will act as a support to fit into the smallest auxiliary receptacles. Simply allowing you to style your tresses without any interruptions.
A Few Additional Features
Apart from the features mentioned above, don’t miss to check the following ones as well:
- Ceramic Plates: Ceramic plate straighteners can heat up to high temperatures and ensure even heat distribution. This results in frizz-free, smooth tresses.
- Small Size: Smaller-sized hair straighteners (6 – 9 ft in total) are easy to carry everywhere. They can even fit in the glove compartment.
- Support 400F temperature: Styling with straighteners that heat up quickly and can reach up to 400F is necessary to achieve excellent results.
- Ionic Technology: Straighteners built with ionic technology tend to result in glossier, damage-free hair.
What are the limitations of using a Car Hair Straightener?
A mini hair straightener for the car is a savior when it comes to instant styling. But there are certain limitations of these hair straighteners. Some of which are mentioned below:
- The hair straightener uses the car battery power which increases the usage of the car battery
- The iron can only be used for basic styling as it is not capable of delivering salon-grade results.
- To use a hair straightener in vehicles other than the USA models, you’ll need to have a universal plug input.
- A straightener that charges in a car usually has a shorter cord, so styling becomes slightly hard sometimes.
