Best Power Inverter For Car – Buying Guide

What Is A Power Inverter Used For

A good place to start this buying guide is to explain how power inverters are used in cars. Some drivers require some electrical devices installed in the car. There are no USB ports and AC outlets in cars.

Cars only have auxiliary outlets where you can add an adapter that allows you to use a device. This is not ideal though. This outlet has a low power supply. More so, some devices can be quite the drain on the car battery.

Power inverters are a medium for converting DC to AC. The power inverter is an adapter with USB and AC ports. It’s connected to the auxiliary outlet or the battery terminals. The inverter can supply enough power to charge and run electrical devices.

Car owners use inverters to power a TV, working lights, GPS, and to charge devices like phones and tablets. Some people use power inverters in emergency situations. When there is a power outage, they use the car’s battery to power some necessary equipment.

How To Choose An Inverter For My Car

Most people don’t know about a certain tool or device until they have a need for it. If you are in need of a power inverter, chances are, you are just hearing about it. So, you don’t have any idea what is the right product for you.

Well, to choose the right inverter you should consider why you need it for. Depending on your power supply demands, you will either need a 300 W inverter or a stronger one. This should be your main concern.

If you need the inverter to power a car TV, to charge phones and other devices, 300 watts inverters are enough. If you want to use the inverter in emergency situations, you need something more powerful that’s suitable for heavy-duty use.

USB Ports & AC Outlets

Think about how many USB ports and AC outlets you will need in your car. The standard is two USB ports and two AC outlets. This is normally enough for many car owners. However, if you need more, look for power inverters with more ports and outlets.

Мulti-Protection

Power supplies like this should be reliable and safe. You don’t want the inverter to damage your car battery and your devices. With poor-quality inverters, this is a common problem. A good power inverter for cars will charge and power your devices and cause no damage.

That’s why you should look for something that has protecting against short circuits, overcharging, undercharging, and temperature overload. If the product can guarantee your devices’ safety, it’s a good one.

You can’t go wrong with products that are up to ETL and UL standards. These products are tested for safety by a third party.

Cooling

I can’t stress how important cooling is. Since you are running DC to AC continuously, the inverter is bound to heat up. This is the worst possible scenario. That’s why even the most basic inverters have a cooling fan for regulating temperatures.

A power inverter without a cooling fan will just cause a short circuit and damage the battery and the devices. The better the cooling design is, the better the inverter is.

Related Questions And Other FAQs

Do Power Inverters Drain Your Car Battery

Power inverters are used on a car with a running engine. If used the right way, a power inverter won’t drain a car battery. However, using the inverter with a turned-off engine or with a high demanding device will drain the car battery. Power inverters are mostly used as a power supply for devices that need a low power supply.

What Can A Car Power Inverter Run

A power inverter can charge smartphones, tablets, and laptops. It can also run TVs, working lights, reading lights, DVD players, GPS systems, and other devices that require a low power supply. Powerful inverters can be used to run working tools and cooking equipment.
