Benefits of the best power inverter for car

Benefits of the best power inverter for carYou may be asking yourself whether you really need a power inverter for your car. The thing is, it’s an extremely helpful tool to have with you so you won’t ever run out of power no matter where you end up. You’ll always have access to functioning electronics that you need in your daily life, and even charge multiple devices simultaneously.

This means you can do more and go further. For instance, if you like to go camping, you’ll definitely enjoy the convenience of being able to use certain tools and appliances like a kettle, coffee maker, or blender. After all, staying outdoors doesn’t mean you have to sacrifice your little comforts.

Moreover, since power inverters don’t run on fuel, rather, they get power from your car battery, you don’t really need to worry about extra costs in operating and maintaining the inverter. This also gives you the benefit of using an eco-friendly device that gives you reliable power without harming the environment.

Types of power inverters for car

Now, the first thing you need to decide on is what type of power inverter you need. Here’s a list of the different types available on the market:

Single outlet

Single outlet inverters come with a simple design and typically give you 150 to 300 watts of power. These are small, lightweight, and portable units that are easy and convenient to store inside the vehicle, and they also come with simple features that help make them more affordable. The downside is, you can only power up one device at a time.

Multiple outlet

Power inverters with multiple outlets, on the other hand, gives you the convenience of charging several devices simultaneously. These inverters come with higher current capacities and plenty of safety features to prevent overheating and overloading issues. However, they are also quite bigger and are more expensive.

USB outlet

There are also smaller and more compact power inverters designed with USB outlets, which are great for charging smartphones, MP3 players, tablets, and other small gadgets. As the name suggests, these inverters come with USB ports to supply power to your electronics, so they are not really suitable for energy intensive household appliances.

Key features to look for in a power inverter for cars

Key features to look for in a power inverter for carsWhen buying a power inverter, there are many things you need to consider, such as the inverter’s capacity, type, and other related factors, all of which we will talk about below.

Peak output vs continuous output

Continuous output refers to the average wattage that your power inverter can supply in normal conditions, whereas peak output refers to the wattage that it is capable of delivering within a specific amount of time.


The wattage of the power inverter is the most important factor as it determines what sorts of devices you can charge or power using the inverter. To give you an idea, 150 to 300 watt power inverters are suitable for small electronics such as phones and laptops, while higher capacity inverters with 1,000 to 4,000 watts are necessary for household and camping appliances.


You also have to consider the number of ports that the power inverter comes with, as this tells you how many devices you can charge at the same time. Generally speaking, more ports (AC outlets and USB ports) are better if you need to power up several electronics simultaneously, but this also makes the power inverter less compact and more expensive.

Sine waves

Power inverters feature either modified or pure sine waves. Pure sine waves are the most efficient in terms of providing consistent power without risking damage to your electronics. Modified sine waves are also quite good at this job, especially when compared with jagged, irregular square waveforms.

Size and weight

What you have to understand is that the size and weight of a power inverter is largely determined by its wattage and available ports. That said, you’ll likely want something that won’t take up too much room inside your car, and is also easy to store when it’s not in use.

Safety certification

All power inverters promise lots of different safety features, but not all of them bear the ETL stamp, which means that the device passes North American safety guidelines in terms of protection against short circuiting, overheating, overloading, and other electrical issues.


You’ll also want to consider the ease of installation and use of the power inverter. Typically, smaller inverters are plugged into your car’s cigarette lighter receptacle, whereas heavy duty variants are designed to receive power directly from the car battery, either via connection cables, clamps, or some hard wiring.

Here’s a brief review of the most popular power inverter brands today:


Ampeak is a known manufacturer of automotive accessories, and has been a staple name in the automotive world for over twenty years. All of its products are also ETL certified, including the Ampeak 2000 watt power inverter.


Bestek is an international company specializing in automotive accessories, electronic devices, and household appliances. It’s a fairly new company founded in 2007, but has already grown with several bases in different countries including the US, UK, and Japan.


Foval’s specialty lies in producing affordable but high quality cell phones and car accessories. This online company lives by its mission of providing unique power tools at affordable costs. The brand’s best power inverter to date is the portable Foval 150 watt car power inverter.


Krieger is a revolutionary name in the industry of solar powers, and it utilizes the same innovations and energy in the brand’s lineup of power inverters. The company has operations in different countries including the US, UK, Australia, France, and Asian and South African countries.


Finally, it’s also a must to have an idea of how much power inverters typically sell for, and what features you can expect under each price range. For example, cheap power inverters under $20 are simple and only offer low capacities of up to 200 watts. These are typically single outlet inverters with basic but pleasing designs.

At the mid-range of 20 to 50 dollars, you can get higher capacity power inverters that boast of multiple charging ports, durable construction, and cooling fans that prevent overheating issues.

And then there are high-end power inverters costing over 50 dollars. These units deliver over 1,000 watts of power, can charge intensive power tools, come with LCD displays, and have a long service life.

Final tips

The best power inverter for cars, in our opinion, is the BESTEK 300W Power Inverter. It’s durable, convenient, and compact, not to mention affordable. Whichever power inverter you choose to buy, however, at the end of the day, what’s important is how to use it.

To keep things safe, remember to disconnect any extra load when you’re not using the inverter to prevent overheating. Even better, disconnect the inverter itself so as not to drain your battery. Or, if you’re using a secondary battery, make sure to place it in a sealed but well-ventilated area.

Furthermore, never place the battery and power inverter in direct sunlight or anywhere near heat and moisture. Also, ensure that you start your engine first before turning on the inverter, and if you use it with the engine off, limit your use to under an hour.
