Are you one of the 38 Million Americans who go camping every year? Perhaps you go on (or are planning to go on) long-distance drives across the state – perhaps even across the country?
Being able to use and charge electrical appliances and gadgets when you are away from home can be extremely useful. Whether this is charging cell phones and GPS devices to staying in touch with the world, or perhaps using equipment like small appliances or air pumps to make a campsite more comfortable, being able to safely generate a solid electrical charge while in the middle of nowhere is very useful.
If that sounds good to you then what you need to invest in is a Car Power Inverter. These useful little devices plug into the vehicle electrical system and convert the vehicle’s electricity into a form that can be used by domestic appliances and gadgets.
There are a range of devices out there, all with different built-in features. We’ve put together this guide of the best Car Power Inverters on the market to help you to find the model that best suits your needs.
Best Rated Power Inverters for Cars in 2020:
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.
- 2x AC Outlets
- 300 Watts of Power
- Built in Overcharging & Overheating Protection
- Brand Bestek
- Model MR13011BY
- Weight 1.16 lbs
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.
- Low Price
- Very Small
- 1x AC and 2x USB Outlets
- Brand FOVAL

- Weight 9.6 oz
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.
- Huge 120 Volt/1500 Watt Output
- Various Built – In Safety Measures
- Useful LCD Screen
- Brand Energizer
- Model ENK1500
- Weight 7.36 lbs
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.
- 12 Volt & Direct Battery Leads
- 500-Watts Constant, 1000-Watts Peak Power
- Built in Cooling Fan
- Brand POTEK
- Model PI-500W
- Weight 1.65 lbs
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.
- 1500 Watt / 12 Volt Output
- Installation Kit Included
- Wired Remote Control
- Brand Kreiger
- Model KR1500
- Weight 5.73 lbs
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.
- High 2,000 Watt Output
- 3x AC Outlets, 1x USB
- Excellent Safety Features
- Brand Ampeak
- Model IVUFA2000
- Weight 8.8 lbs
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.
- Incredible 2500-Watt Power Output
- 3 AC Outlets, 1x USB
- 5 Levels of Safety Features
- Brand Cobra
- Model CPI2590
- Weight 6 lbs
Best Power Inverters For Cars Buying Guide
There is our list of the best power inverters on the market today. As you will have seen, perhaps more than some other items we look at here at Car Bible there really can be a huge difference in the capabilities and features found in the products at either end of the price spectrum.
It’s really important to select the right model too, as selecting one that is too underpowered will result in an inverter that can’t supply electricity at the level you need. On the other hand, these can be pricey tools, and you don’t wan to drop big bucks on an overpowered model that is pumping out 2,000 watts of power to just charge your cell phone.
To help you select the right model for you then, lets take a look at some of the features that are common amongst these products, and also answer a few of the more frequently asked questions about car power inverters.
Types of Car Inverters
Whist there are a number of features that can differ from one model of inverter to the next, the biggest difference between models is found in how they connect to a power source.
The two types are then:
- Easy to use, simply plug it in and away it goes.
- You don’t have to leave the vehicle cabin to operate.
- You can plug it in as you drive.
- Can only generate a lower power range – about 500 watts max.
- Can generate a lot of power – enough to operate electrical items like coffee makers, fans and lamps.
- Only work when vehicle is pulled over.
- Have to connect/disconnect every time you want to drive
- Can be large and bulky and also noisy
As we can see the how they connect will have a big impact on how they work. A connection through the 12 Volt charger found in your vehicle cabin simply cannot provide the level of electricity that you will need to operate power hungry electrical goods, but it will be simpler to use.
This is probably the biggest consideration you need to make when you are choosing which model you are going to select.
Factors to Consider When Buying a Power Inverter
Here are some of the factors to consider when choosing an inverter. Consider which you need, and which you can do without, to make sure you buy the right model, at the right price.
Purpose – Probably the biggest factor is the purpose that you want to use the inverter for. If you just want something to keep in the car to charge up your phone or GPS every now and then, you can get away with a smaller sized device with a 12 Volt adaptor. If you are an outdoorsman (or woman) however, and you want an electrical supply when you are pitching camp in the great outdoors, you may need something more powerful.
Size – This connects with the above somewhat as there can be some significant difference in size between the different powered inverters. If you just want to charge your phone, you can pick up an inverter that weighs less than a pound, is only a few inches long and can happily tuck away in the glove compartment until needed.
Safety Features – A good inverter will have good safety features to protect both itself and the items that it is charging. Look for surge protection & short circuit protection to prevent damage to your electrical goods, and temperature protection (and a good cooling fan system) to protect itself. Premium models will also run their power supply through multiple, internal mounted fuses. They will add an extra level of protection.
Price – Just as with any purchase, have a budget in mind and stick to it. The prices for these types of items run from under 20 bucks to over 200. You are, to a certain extent, getting what you pay for though. A lower priced inverter is going to struggle to generate the power you need to run large electrical devices. On the other hand, a higher priced one will probably come with more safety features, making it better for the long-term operation of appliances.
Best Power Inverters For Cars FAQ:
If you have any questions about power inverters, then you should find all the answers here (we hope anyway!)
Q: How Does a Power Inverter Work?
The first thing you have to know is that your car battery (and by extension the car electrical system) provides a DC electrical supply . DC, or Direct Current, is required because this electrical system can store and deliver energy in one big push – exactly what is needed to turn the engine over and get it started. The outlet in your wall however is an AC – Alternating Current – electrical supply. There are many reasons for this but it’s mainly to help with transferring energy efficiently from the production point (the power station) to your home. An inverter then merely work to convert the DC electrical supply generated by your car battery in an AC supply that can be used by electrical goods that are usually plugged into domestic sources. Simple!
Q: How Long Does a Power Inverter Work?
The inverter will continue to work so long as it is supplied with an electrical current that it can “Invert” – or change from DC to AC. As far as overall product life span goes, as with any device an inverter won’t last forever. A typical lifespan would be about 5 to 10 years for an inverter, depending on build quality, storage and usage. Bear in mind there are quite a lot of moving parts, as well as electrical elements like screens on many of these devices. It may not be safe to operate without a fan to cool down the inverter, and the small fan motor could well burn out before the inverter itself. As with any product, you basically get what you pay for!
Q: Can I Use a Car Battery for the Inverter?
Yes, you can – but sometimes it may not be a good idea to do so. It’s recommended that you don’t regularly drain a car battery lower than 90% total charge. A small inverter that you are plugging into the 12 Volt charger inside the vehicle, just to charge a cell phone for example, is not going to cause any problems. There is simply not enough space in the cell battery to displace 10% of the car battery charge . When you are plugging in the larger inverters however – that is where you need to be careful. A 2,000 Watt inverter can place a strain on the battery, so you must be careful when hooking up electrical devices to the more powerful inverters. This is especially true if the vehicle is going to be stationery for a while, such as if you park up at a campsite for a few days. When the vehicle is still the battery is not charging. In this instance, consider running the engine frequently to top up the battery charge level. For long term stops, you could pack a few extra car batteries to hook up to the inverter instead of the installed car battery. You can even create a ban of batteries for a continued, even electrical supply.
Q: Do Car Inverters Drain the Battery?
Yes, they do so you must always be careful to monitor them during use. Naturally, the more power the inverter, and the more devices that are run off it, the quicker it will deplete the battery. A small, basic charger throwing out 100 Watts to charge your IPhone is not going to cause a problem. A big inverter that is sucking 1000 watts out the system to run a hairdryer and a water heater at a campsite is something to monitor! Also – bear in mind that many older vehicles do not have auto shut off to the 12 Volt charger in the cabin. If you leave the inverter plugged in then, it may continue to work inverting power even with no devices plugged in. Keep it safe and unplug the inverter when not in use.
