Best Power Inverter in 2018 : Recommended pick you buy this year

(Last Updated On: September 27, 2018)

Sine Wave Inverter

A car power inverter is a simple device that uses the power of car battery to run electrical appliances such as chargers or laptops. 

These automobile inverters provide you the ability to charge your laptops, tablet, iPhones, etc while you are traveling in your car. So, the next time while you are on your camping trip, carry these devices to stay connected with your family back home.

The power generated by a car engine is DC voltage and the inverter converts it into AC voltage so that electronic devices can use it efficiently and thus, these are called AC inverters. (Source)

Understand the functioning of Car Power inverter 

Before you can understand the functioning of the car power inverter, it is necessary to understand the AC and DC power and the difference between them. The power what you get from the outlets of your home is AC power and that you get out of the batteries is DC power. Car batteries provide low-voltage DC power. If you want to use the consumer electronic devices on the road which work on AC voltage, you have to install the equipment that is known as car power inverter. The power inverters convert direct current (DC) into alternative current (AC). This will help to use electronic devices in the car.

  • Essential factors

In case of using car power inverter, the critical factors that should be kept in mind are the capacity of the car battery, output wattage of the inverter, and rated output of the alternator. The battery can provide service until it goes dead. So based on these factors you have to determine which portable devices you can safely use in the car. The devices like cell phones and laptops work fine using with the 12V attachments like cigarette lighter adapter.

  • Functioning

Inverters work by using the unidirectional DC power to mimic the AC power source. Modern inverters are made with transistors or semiconductors. This inverters act as oscillator switching the polarity of the DC power source rapidly to create a square wave which is not like smooth, round perfect sine wave. Alternating current or AC forms a sine wave. Some devices like audio or video equipment, navigation devices or sensitive scientific equipment are inherently sensitive to the signal generated by an AC wave.

Most consumer electronic goods require something nearly to a pure sine wave.  The inverters are mainly of two types, one that generates a modified sine wave and the other which creates a pure sine wave. The extra components required for cleaning up the sine wave are a series of filters, inductors, and capacitors and thus create either a modified or a pure sine wave.  The inverters with modified sine wave are affordable but have little or no filtering. This works fine with the devices like a coffee maker with the simple electric motor. Where the devices require smoother sine wave, you need the inverter that does filtering better. The inverters with pure sine wave are expensive. If your budget allows, you can definitely go for AC car power inverter that creates perfect AC sine wave. As the devices that you require to use in the car are dependent on the functioning of car power inverter, try to install the one which suits the best as per your requirement.

Important Factors:
If you want to find the best power inverter for
the car then you need to keep a few points in your mind. Capacity of the car battery, rated output of the alternator and output wattage of the inverter are few vital constraints to take care of.

  • We know that inverters produce heat and need ventilation. Some inverters have in-built fans but they consume electricity in order to run it. So kindly take care of the temperature in which you are using a power inverter.
  • The battery of the car should be able to keep up and hook up power for the inverter.
  • Power inverters hook up a larger amount of power. If the car engine is running and inverter is consuming power then it is okay. But if the inverter is hooking up power while the engine is off, it can over consume the power of car battery.

The requirements of power inverter:
If someone is constantly traveling or spends most of his time on road, power
inverter can be quite useful. It is specially designed for corporate people who need to travel a lot, truck drivers or people who are camping.

Though electrical devices like laptops and phone chargers can be directly used with 12v attachments that plug directly into the cigarette lighter jack. But there are devices which can run only on AC input. Some examples of such devices are:

  1. Televisions
  2. Video games and Game systems
  3. Video cams
  4. DVD Players
  5. Cooking equipment

Types of Car inverters:
Based on their working, power inverters can be basically divided into two parts:

  1. Modified Sine wave: This powerful power inverter produces modified sine waves which is suitable for most of the consumer electronics. These kinds of inverters are affordable of the two.
  1. Pure sine wave: This kind of inverter produces pure sine waves. Pure sine waves are very much closer to the actual AC power available at our homes. There are devices which only work on an uninterrupted power supply and hence sine waves are required. This kind of inverter tends to be expensive.

 How to choose the right car inverter 

There are plenty of car power inverter brands available in the market ranging between hundreds to thousands dollar. You have to choose the best power inverter for your car, and it is essential to select the right size. But it is dependent on how do you want to use the inverter. You have to decide certain things like:

  • The number of inverters you would like to use. The inverters come with 1-3 outlets, so you have to choose the right size as per your needs. You have to decide on using cigarette lighter adapter for flexibility and portability or the hardwired permanent installation. The thumb rule is that with the loads more than 150 watts you require a direct battery connection.
  • How much current the equipment will draw that you use in the car. Small appliances can run using any inverters, but the heavy appliances require inverter with large capacity and direct connection to the battery.
  • Domestic User and Outdoor worker

For the regular domestic user, the car inverter with the maximum power limit 200 watts is more than sufficient. The majority of family cars with 12v secure current supply that is less than or equal to 20A is fit to use appliances that are approx. 230watts. The old cars also have the supply of 10A, so you don’t require the inverter with high capacity. In this case, the cigarette lighter adapter can be used for the appliances below 150 watts. For the outdoor workers who need to use electrical devices with high power, need to have inverters directly connected to the battery. This battery connected inverters can supply power 500 watts or more to drive small motors as well as higher power devices with 1000 watts or more.

  • Modified sine wave and pure sine wave

There are two types of car inverters in the market for sale, one with a modified sine wave and another with a pure sine wave. These inverters have a big difference in performance. The price is higher for a pure sine wave, but the performance is outstanding. The output quality is much better than the regular AC grid power. The use of high-end devices like video, gaming or navigator devices requires inverter with the pure sine wave. On the other hand, there are cheaper inverters with a modified sine wave. The guarantee of stability can be given in most cases for these inverters, so it is cost-effective to the buyers.

Above all, the maximum allowable current for the fuse of automotive 12v DC power supply should be kept in mind as that cannot withstand high power. So do not buy the high power inverter blindly or use the electrical appliances of high power. In that case, you will burn the fuse of the car, and instead of having any benefit it will cost more.
