The Best Power Inverters for Cars (Review & Buying Guide) in 2023 | Autance

Let’s start with this model from Bestek, which has a very low price tag. Despite that low price, there are a number of very useful features on this device.

The fact that it comes with not one but two AC outlets is great and should stop at least some of the arguments over whose cell phone gets charged first. It also has a pair of USB ports that can power devices, and  you can charge up to four devices at a time. However, with a total output of only 300 watts, it will struggle to charge that many. But it will happily charge a couple of devices at a time with very little strain.

The built-in cooling fan is constantly in operation, which can make it a little noisy, but all in all this is a very well-designed inverter with a very reasonable price tag.

Next is this adorable little inverter from FOVAL. Packing only one AC outlet and two USB ports, plus a total output of only 150 Watts, this is a pretty basic device with low overall power.

However, this device is not designed to power up an entire campsite. Instead, look at it for what it is, and you will see that the key selling point for this device is its tiny size. It weighs less than 10 ounces and is less than four inches long.

That makes it ideal to tuck away in the glove compartment and pull out every now and then to charge a phone or GPS device. Consider it a handy back-up device that is actually a very well-designed little tool, bursting with useful features and boasting a fairly low price tag.

Energizer is a well-known brand when it comes to batteries and power supply products. What it brings to the market is a premium model with many useful features and a very impressive level of electrical output.

Two AC outlets and two USB outlets are powered by an inverter that can generate up to 1500 watts of continuous power, which is more than enough to charge a device in each outlet without breaking a sweat.

It has a max power output to run small electrical devices, making it  perfect for setting up campsites. It also boasts all of the safety features you would expect on a high-end, powerful inverter. There is overload, temperature, and short circuit protection along with a very useful LCD display that easily allows you to monitor power usage in real time.

However, all of this power doesn’t come cheap. While not the most expensive option on our list, it is certainly not the cheapest. It also weighs about 7.5 pounds, making it a bit bulky to pack and carry.

This device from POTEK is an interesting design because it provides a best-of-both-worlds approach to power inverting. We previously looked at devices that come with a connecter to a 12-volt charging port inside the cabin. We also listed an inverter that connects directly to the battery.

The 12-volt connectors are easy to use but only generate limited power; the direct connection brings a big power charge, but it is more awkward to connect to the power source.

This model does both. When plugged into a 12-volt charger it generates up to 500 watts of power that is distributed via two AC outlets and two USB outlets, which are perfect for charging devices.

If you hook it up directly to the battery it can throw out up to 1,000 watts of peak power, enabling you to run more power-hungry devices. A built-in fan keeps it cool at higher workloads and only kicks in when over 200 watts of power is being used, so it’s nice and quiet when simply charging batteries.

A very useful, well thought-out design with a very reasonable price tag makes this a very appealing inverter.

This inverter from KRIGER is designed to do far more than simply charge batteries and electrical devices; however, it certainly has the power and outputs to handle those tasks very easily.

This is really designed as a built-in inverter, and it even has an installation kit on the body so you can mount it vertically on to a wall or on another solid feature. It includes a wired remote control, so you can turn it off without having to leave your caravan or tent.

As a device that throws out considerable power, it comes complete with the level of safety features you would expect. This includes built-in protection from temperature extremes, overloading, and short-circuiting.

This is a premium item, so expect to pay a premium price. But if you rely on access to a good level of power while out and about, this could be a very worthwhile investment.

This product from Ampeak is a very powerful inverter, bringing 2000 watts of power to the party. That is not quite as much as the next model we list; however, it is far cheaper than the Cobra brand inverter below. For pure dollar-to-power conversion, this one is a great option.

All that power needs significant safety features if it is to be used properly, so it’s good to see Ampeak has taken safety seriously. We have the usual protection from heat, over charging, and short circuits. We also have no less than 10x 35 amp fuses built in to the inverter, while three fans help to keep the product cool at all times. 

Weighing in at almost nine pounds, this is the largest and heaviest inverter on our list. It also has a hefty price tag, making it one of the more expensive products on our list. If you don’t mind either of those facts, this really is a premium product that has the design, build quality, and features to justify a high price tag.

Finally, we have the king of car power inverters. If we’re going to talk about this product, the first thing we have to do is take note of its output, which is 2,500 watts of power.

All that power runs through three AC Outlets (and one USB), so you can run three appliance-size electrical goods as well as charge an electrical device at the same time. If you want the power to set up a home away from home, then this could be the inverter for you.

All that power is protected behind five stages of safety features, protecting against high and low voltage shutdowns, temperature spikes, and pretty much anything that could go wrong.

The easy-to-read screen provides useful read-out information on the current power, making it easy to monitor battery usage and drain levels.

This is not a cheap model. In fact, with its somewhat costly price tag it is by far the most expensive. However, for that money it is going to deliver a very high level of power, and it’s going to deliver it safely.
