Gaming PCs are likely out of the question, though. Even without the fan, it still works quietly, so you won’t be disturbed. There’s a mounting kit included so you can charge while driving with convenience. However, the placement of the outlets and ports may make it a little difficult to charge multiple devices at once if your plug is bulky.

It delivers continuous power and brings with it a durable metal housing to keep the parts safe and fail-resistance. The cooling fan keeps it silent, even with multiple devices plugged in, but like any option on the lower end of the wattage scale, you won’t get as wide of a variety of applications as those that cost a more.

Our final pick of the best power inverters for cars is the compact and convenient BESTEK 150W Power Inverter. This gadget includes patented isolated voltage protection for excellent performance, as well as 1 AC output and 2 Smart-USB ports which easily recognize your device and prioritize the correct one.

Because of the Smart USB feature, it’s possible not all ports will charge at the same time, at least not like you want them to. However, we’d say this is a small price to pay for what is essentially a very affordable and very useful little power inverter.

Next up, we have the most powerful inverter on this list. With 2,000 watts of power, it converts 12V DC into 120V AC power, allowing you to use power tools, charge laptops, and much more. The unit has two standard North American AC outlets, which comes as standard across almost all car power inverters. However, this one comes with an additional two USB ports for charging phones and other small devices. This is an excellent addition for camping, tailgating, and more.
Because of the relatively high power output, these units can run pretty hot. Fortunately, the designers of the Krieger 2000 Watts Power Inverter have taken this into consideration. It features large aluminum heat sinks that deliver enhanced dissipation to stop the unit from burning out. This also has the added benefit of making the unit last longer, which is something we can all get behind.

Power Inverter For Cars Buying Guide
What Are Power Inverters For Cars?
Power inverters for cars are devices that you can use to convert DC current to AC current. Considering your car runs using Direct Current (DC) but smaller devices like your smartphone or tablet us Alternating Current (AC) you need a power inverter to convert this current if you want to use your car to power or charge.
Be careful not to get confused Power Inverters with Power Converters, which do the opposite of an inverter by reducing AC voltage to the 12 to 25 volts used with DC.
Features To Look For In Power Inverters for Cars
Before you decide which of the best power inverters for cars are the right one for you, make sure to check out this useful guide of the key features to think about.
Power Rating - The higher the power rating (in watts) the more juice you will be able to provide to your devices. Most power inverters offer between 100 and 3000 watts, and the majority of users won’t need anything more.
To put it into perspective, 300 watts can power a TV, so if you just need a power inverter for charging smartphones, you don’t need anything larger than this. You might need to power larger appliances, though, so if so, take a look at more powerful options.
Number of Outlets - More outlets increases convenience, but it also means it will spread the power supply across all outlets that are in use. Most inverters offer both AC outlets and USB ports to give you options for charging multiple things at once.
USB Ports - Speaking of USB ports, most devices offer 2 ports, but some provide four. It all depends on the manufacturer. These are convenient, as they allow you to power larger appliances that are not USB-ready while also charging phones, tablets, and laptops.
Connectivity - Most inverters will connect to the cigarette lighter port, but whether this is what you need will depend on the intended purpose of the inverter, and also the maximum power output of the lighter port, and anything that’s too large could cause a short circuit.
More substantial power inverters do not have the lighter connection, and it would be too difficult to attach anyway considering the size. In instances such as this, you’ll need to connect the inverter directly to the car’s battery. Make sure there is a reverse polarity alarm to ensure you attach the ends to the correct place.
Cable Length and Materials - Cable length may not seem that important compared to other options, however, there’s nothing worse than buying something and realizing it won’t fit where you want it to because the wire is too short. Likewise, you don’t want to clutter up your car with an extra-long cable, as this could become a hazard. Think about where you want the inverter to go, and then look at options with that cable length, but also allow for a bit of give just in case.
The materials used for the casing should be durable and lightweight to make them easier to handle. However, you also need to ensure they do not heat up too much and damage the casing.
Safety - There are a few key safety features to look out for when shopping for a power inverter. These include automatic shutdown, built-in surge protection, soft start tech, and cooling fans.
When combined, these features prevent overheating and overloading, which could damage your car, the ports, or worse.
Remote Control - Remote controls are useful, but not essential, and while some options come with remote controls, not all of them do. They can be convenient, but don’t get too swept up in the fact that you need one, because most of the time you won’t, especially if you are driving at the time.
Price - There is a wide, but not too wide price range when it comes to power inverters, but typically this is purely because of the features offered. Basic power inverters are cheap enough, with many being less than $20 and they provide a simple charging solution for road trips. However, those with more substantial features, such as jump starting will cost more. It’s all about what you need from a power inverter.
Warranty - While most power inverters are not too expensive, it’s still beneficial to look at the warranty agreement before purchasing. This is because you are working with electronics which despite being mostly foolproof, there’s always the chance that something could go wrong.
If you plan on using your inverter regularly, then a warranty is essential, and even if you don’t then at least you can have the confidence that you will be covered following any issues should your inverter malfunction.
Types Of Power Inverters For Cars
Modified Sine Wave - A modified sine wave inverter uses a more straightforward process compared to a pure sine wave. However, despite this relative simplicity, it is not something you find often with modern technology. Modified sine wave inverters are not ideal for sensitive devices like laptops, and anything with microprocessors could overheat if exposed, so keep this in mind when shopping around.
Pure Sine Wave - A pure sine wave inverter generate clean waves as opposed to the more square waves of their modified counterparts. These may be more expensive, but it will be better in the long run for your devices and accessories. They are better for smartphones and experience less risk of shutting down.
