Why choose the best car inverter?
A car inverter is a device that converts direct current into alternating current . This conversion raises the voltage, allowing you to connect most of the appliances you have in the house. This will allow you to charge portable devices such as your phone, tablet or laptop .
Also, if you go on trips often you can use the car inverter to connect a coffee machine or a mini fridge to keep food fresh on the road. A car inverter can also be useful when working in an area where there is no electricity .
For example, photos and videographers always need to charge batteries and other devices to be able to take pictures in the most isolated places.
You can also use such a device for entertainment, connecting DVD drives or even game consoles.

So, to choose the best car inverter, here's what you need to know:
How does a car inverter work?
To understand how a car inverter works, you need to know the difference between direct current (DC) and alternating current (AC).
DC power sources are batteries that always have a negative and a positive side. The electrons come out the negative side to power devices such as the radio, horn or headlights of your car, then it returns through the positive side and the cycle continues.
Alternating current, on the other hand, is used in the home and works differently. In this case the electrons always and constantly change their direction, about 50-60 times per second . This movement generates heat , which powers the lights, appliances and computers.
Car inverters function as a converter that changes DC to AC using electromagnetic force. Thus the voltage offered by the car increases.
In the case of most conventional cars the lighter current is 12 V (volts) , while in large cars, such as trucks, the current is 24 V , however most devices need a current of 220 V , as found at a normal outlet .
By converting DC to AC this voltage is obtained and it is allowed to connect the desired devices to the power source provided by the machine.
Compatibility is made with the car battery and the maximum supported amperage as well as its voltage must be checked.
When we talk about the amperage of the car, we are talking about the current intensity that can be supported by the battery. This value is shown in Amperes (A). You will need to check the input amperage of the devices you want to connect, as well as the maximum supported amperage value.
The easiest way is to check the power of the inverter expressed in Watts (W), because this is the product of multiplying the amperage by the voltage of the inverter. For example, for a 3000 W car inverter , and a 220 V voltage , the amperage will be 13 A.
In the car book you will need to check the maximum supported amperage to make sure these values match. You should know that in the case of older cars, the maximum supported amperage is 10 A , which means that you are limited to connecting a lower power inverter. There are also models that support an amperage of 15 A or 20 A.
The next value that the inverter must be compatible with is the car battery voltage . It can be 12 V in the case of a conventional car or 24 V in the case of a large car. The inverter must be able to work with the voltage of the battery on your car.
Car inverters available on the market can have a power, expressed in Watts (W), which starts from 50W and can reach 50,000W . Depending on which devices you want to connect, you will need more or less power, but most drivers find enough power up to 2000W.
To give you an idea, 300W is enough for a TV, and 600W is enough for small tools. 2000W is more than enough for hair dryers and conventional devices.
A power greater than 200W will only be used when you want to connect several large appliances at the same time. A good idea is to make sure it has more power than you intend to use. This way you will be prepared for unforeseen situations.
Type of operation
There are two types of operation: pure sine wave, or modified.
Car inverter with pure sine wave
It is the cheapest category on the market , but also the most defective, which is why you will have to check it frequently. This inverter works with high amperage values, and at frequencies of 50Hz (hertz).
It is also the category in which complications are quite common. As a result, focus on professional models.
You will be able to connect battery chargers, battery packs, stereos, digital watches or high power tool chargers to such an inverter. All will need to have an alternate adapter.
Car inverter with modified sine wave
The best car inverter falls into this category. These devices are able to provide electricity for several devices, without having to worry about radio disturbances.
Several devices fit very well with such a car inverter including: laptop, smartphone, camera, tools with low power motors, mini refrigerators, TV, game console, microwave, etc.
Number of outlets and ports
You will find on the market models that have one or more sockets . Of course, the more there are, the higher the price of the product.
The single – socket car inverter usually has a power of 150W – 200W . They are small and cheap and can be connected to the car lighter. The higher the number of sockets, the higher the current capacity and power.
The number of sockets depends a lot on your personal preferences and how many devices you will need to be connected simultaneously.
It is also useful for the inverter to have a USB port . It will allow you to charge devices such as your tablet mobile phone or other similar devices that can be charged via USB cables. However, there is not much difference between using a standard socket and a USB port.
Connecting to the machine
Find out how to connect the car inverter to your car. Will you be able to use the car's cigarette lighter? The choice will depend on how you intend to use it.
Usually, the car inverter will be able to connect to the car through its lighter . If this is the case with your inverter, check the current intensity that the lighter can withstand and make sure the inverter amperage is less than this value.
Larger car inverters will not be equipped with a cigarette lighter connector, which means you will need to connect them directly to the battery .
Currently, car inverters are equipped with several safety measures that have the role of protecting the vehicle against possible damage. These measures include:
- Auto shut off : The car inverter closes to prevent battery drain.
- Overvoltage protection : Its role is to protect devices against electrical fluctuations.
- Slow start technology : Provides protection against electrical fluctuations, short circuits and extreme temperatures.
- Fans – Prevents the car inverter from overheating.
Size and weight
It is good to choose a car inverter that will be practical for the way you intend to use it .
If you are looking for a car inverter to use only on holidays and car trips, it is recommended to opt for a small model, which is very portable and can be connected to any vehicle.
Otherwise, choose a device that takes up as much space as you can provide, especially if you need an inverter with multiple outlets.
Most car inverters are protected by a strong housing to protect them from falls and other damage. These are aspects that are good to check, because a case made of a hard material will last longer, and you will be able to use a car inverter for many years.
It is also important that the inverter is equipped with cooling fans, as they will prevent short circuits that can shorten the life of the appliance.
Before buying a car inverter it is advisable to check the type of socket . As you probably know, Asian and American outlets are different from European ones .
As a result, if you buy an inverter that does not have a socket that matches the ones in Europe, you will have to buy an adapter, which is an extra expense that you do not want to worry about.
Price and manufacturers
As we noted above, the price of an inverter varies greatly depending on many factors such as: additional functions, number of outlets and ports, power , etc.
Although more expensive models tend to be more efficient, it is not always a good option to buy the most expensive product. This is because there are many chances that you do not need all the power or sockets it offers, which means that you will never be able to capitalize on your investment to its full potential.
It is also a good idea to check the car's inverter manufacturer. Don't buy a no-name product , because there are chances that it is defective products that can damage your car or the devices you connect through the inverter.
Here are the most appreciated brands available on the Romanian market: Trust, Waeco, Albrecht, Kemot . Buying from a manufacturer that has a good reputation, you have more chances to choose a very high quality product.
We recommend that you buy the best car inverter online . This way you will be able to find one that fits your needs very well, and you can buy one at a very good price, because special offers and discounts are more common online.
Before making any kind of online purchase, don't forget to check the opinion of other buyers. If they have had a bad experience with the product you are interested in, you may suffer the same.
You are now ready to buy the best car inverter.
