Best Power Inverter For Car FAQ:

What is a Power Inverter?

A power inverter is a device that helps convert a Direct current (DC) power to alternating current (AC) power. Its primary purpose is to convert and step up the voltage from low DC power from a car battery to a standard AC power output. Thus this allows you to operate your devices and household electrical equipment that usually requires enough electrical power to work. All you need is a truck or car battery and an inverter, and you are ready to go.

How Does a Power Inverter Work?

First of all, you have to understand that your car battery produces direct current (DC) power supply that ranges from 12V-24V depending on the battery. The amount of power supply provided by a car battery is not enough to power and charge your devices faster and adequately. Therefore, power inverter comes in play, it helps to convert and step up 12V dc input power to around 120V power output and 24V power input to about 220V power output. That AC output power is big enough to power most of your devices at once.

So, an inverter works by converting a direct current power to a standard alternating current power supply simple!

What type of inverter do I need?

When it comes to choosing a suitable inverter, there are two types; therefore, you need to choose depending on the purpose you expect that inverter to accomplish. So, is it a 12V inverter or direct connection inverter/charger?

12V inverter: If your desired primary use is to charge your smartphone, tablet and power your laptop, then portable 12v inverter will be a better choice for you.

Direct connection inverter/charger: These types of inverters will be essential if you’re looking to power bigger devices like fridge, TV, dryers, etc. This is because they will provide enough power for you to operate effectively.

Can I use a car battery for the inverter?

Yes, you can. These inverters are specifically designed to work with cabin USB ports or to be an alternate choice, which means it will be using your car battery. A smaller inverter (12V) is intended to be connected inside your car by plugging it into a 12V charger inside your car. Hence you can easily charge your phone and laptop while on the road, and it won’t cause any issue. On the other hand, the bigger powerful inverters working with 24V input power are mostly connected directly into the car’s battery and are disconnected while driving, unlike 12V input inverters.

Note: It is advisable that you don’t drain more than 90% of your battery’s total charge and it is not a good idea to use power inverter regularly.

Can a battery get drained by using car inverters?

Yes, car inverter does drain your battery if you’re not careful. Powerful inverters quickly drain power from your battery since they allow you to connect to multiple devices. For instance, if you run a heater or hairdryer, a bigger inverter will have to drain at least 1000W from your battery hence you need to monitor it to avoid the power in your battery from being drained.

Another thing to keep in mind is that you need to disconnect your inverter whenever you are not using it mostly if you own an old model vehicle that doesn’t have auto-shutoff in the cabin charger.

Do I need an inverter with any special features?

Yes, mostly if you are using sensitive and powerful equipment such as computers. Here are some of the features that your inverter should have in the case that you are running sensitive devices.

High initial power: This feature is vital if you are running devices that have high initial power such as pumps, compressors and motors.

Models with GFCI outlets: If you are to work in a wet environment most of the time, then you will need an inverter that meets OSHA requirements. This will offer you a safe operation.

Sine wave output and fast transfer times: Model ofInverters with these features are ideal for operating sensitive devices such as network equipment and computers.

How long does a power inverter work?

Daily operation -Since every inverter depends on the battery input power, therefore, every inverter will operate as long as the input power is available.

Life span- Inverter doesn’t last forever, so when it comes to the product’s life span, it estimated to about 4-10 years depending on the usage and maintenance.  

There are special features such as shut off/shutdown and cooling system that protects and helps it to last longer.
