We’re more reliant on technology than ever before. Do you go to a restaurant without checking out reviews online first?
And when was the last time you drove anywhere without Google Maps on your phone, guiding your way?
Our growing reliance on our electronic devices leads to a corresponding need for power. And when we’re on the road, there’s a source of power that should be at our fingertips, but it’s just out of reach.
Our car’s battery offers the potential for charging phones, laptops and tablets, or powering the kids entertainment in the form of TVs and in-dash car DVD players.
If you’re camping out, the car battery could even power your minifridge, or coffee maker in the morning.
And in a disaster scenario, our car’s battery is a power plan B. It could keep the lights on, or save your frozen goods from spoiling.
But car batteries produce DC – direct current. And our household outlets provide AC, the alternating current required to charge batteries and power appliances. To turn your car battery into an on-hand power source, you’ll need a power inverter.
These inverters go from pocket-sized and plug-in to the hard-wired. But whatever your electrical needs, there’s a car power inverter for you.
Let’s take a look at the best car power inverters on the market.

The Buyer’s Guide To Car Power Inverters
That was the best of the best. But whether you’re powering a fridge-freezer in your trunk or just looking to charge your phone should guide your choice. Overkill on inverters is just a waste of money.

Here’s everything you need to know about car power inverters to help guide your choice.
What is a power inverter for?
Your vehicle is packing a lot of power. Car batteries are arguably wasted under the hood, where excess power is used to start your engine – and not much else.
Nowadays we’re surrounded by gadgets and gizmos that could use a hit of power. Turning your car battery into a backup source of power makes sense. But car batteries are geared towards a specific 12v direct current output – and to charge your phone or power your appliances, this has to be converted to the household standard of 120v alternating current.
That’s where an inverter comes in. Installing an inverter allows you to power a wide variety of items from the front seat.
Whether that gives your phone the juice to navigate your home, or you install a minifridge to keep the beers cool for when you arrive is up to you.
Perfect For Camping
Power inverters turn your car battery into an all-purpose generator. You can power a range of lights, coffee makers and barbecues straight from the bonnet, everything you need to bring the creature comforts into the wilderness.
Inverters that can handle massive wattage and have multiple outlets are ideal for camping trips.
In Case of Emergency
When hurricane season approaches, it’s wise to have a plan for backup power. Even relatively mundane power outages can leave you out of luck as your fridge-freezer defrosts and your computer powers down.
A car power inverter is a versatile option – it’s handy for keeping your electronics charged on a daily basis, but comes into its own in a disaster scenario. Check the wattage of your prized appliances, and plan accordingly.
If you’re going to run your household appliances from your car battery, remember you’ll need long enough leads to hook them up. Extension cords will be an essential added purchase to bring the outlet into your home.
What Wattage?
When you’re powering appliances, wattage is vitally important. The wattage of your appliance indicates how much power they draw, and a high-wattage appliance plugged into a low-wattage inverter is a recipe for disaster.
Trying to draw more power than your inverter can provide will result in blown fuses, damaged appliances or even overheating and the risk of a fire. That’s a distraction you don’t need while you’re driving!
Pick a power inverter that can handle everything you might think to throw at it. Charging your phone or your camera’s battery will draw very little power, whilst powering a TV or laptop will use in the range of 100 watts.
Mini fridges will use around 100 watts, whilst bigger household refrigerators might draw more like 300 watts.
Power tools and PA systems turn it up a notch, requiring wattage in the thousands. Make sure your inverter is up to the task.
What’s more, your car’s battery has only a finite amount of power. If you’re planning on powering anything over around 100 watts, you’ll need to leave the car running to ensure the alternator is recharging the battery.
The Installation Process
There are typically two ways you can install a power inverter.
1) Plug-in
The majority of cars feature 12v outlets – you likely know these as the cigarette chargers in older vehicles. Many lower wattage power inverters simply plug into these outlets, creating a 120v power socket in the cab.
2) Hard-wired
For higher wattage inverters, the process of power conversion requires hard-wiring to your car’s battery. Installation will require a little bit of fiddling with the wiring, but it should be achievable for anyone with an inclination towards DIY.
Look out for the inclusion of wiring kits with your power inverter, otherwise you’ll be left running to the hardware store before you get the power going.
Things To Look Out For Before Buying a Car Power Inverter
From budget to baller, there is a range of features you might want to look out for in a car power inverter.
1. Safety Features
If your inverter is drawing a lot of power from your battery, there’s a real risk of overheating. And surges could pump excess power into your appliance, damaging the battery or frying the electronics.
Overheating and overloading protection are found with most of the top-end car inverters and they offer you added security. From fire risk to device protection, these safety features have you covered.
2. LCD Screen
An LCD screen isn’t essential, but it’s a great bonus and can offer you tons of information about your device, giving you extra knowledge and security.
Screens can display information about wattage and power, indicate if there’s any risk of overheating or help you keep a close eye on the health of your car battery. Without an LCD screen, you’ll be left in the dark.
3. Number Of Outlets
A power inverter is a big upgrade for your electronics – but don’t be left disappointed when you can’t power all your devices at once. Some inverters come with a single power outlet, allowing you to charge a phone or laptop, but not much else.
And these days, we have almost as many appliances powered by USB. Some inverters will contain multiple outlets and USB ports, providing you with the ultimate electronics hub in your front cab!
Of course, multiplying the outlets creates a greater drain on your battery. If you’re opting for multiple outlets, make sure your inverter has the wattage to cover all your devices and keep an eye on your batteries level to avoid getting stranded.
4. Pure vs Modified Sine Wave
Time to get technical.
Car power inverters will output voltage in either a pure sine wave or a modified sine wave signal to power your electronics and appliances. A pure sine wave takes the form of a seamless wave, providing smooth power.
A modified sine wave actually flickers between positive and negative, creating a square cut blocky signal. Compared to a pure sine wave’s curves, it’s inelegant.
And it’s not just to the aesthete’s eye that the difference is apparent. Your appliances can tell the difference too.
Anything with an AC motor, from tools to microwaves, will perform suboptimally with a modified sine wave.
Sensitive medical equipment and some modern TVs also require purity from their sine waves!
When it comes to car power inverters, you’ll be paying extra for a pure sine wave inverter. In fact, these elite products are still a relative rarity.
And if you don’t want to pay through the nose, don’t panic. Your appliances will still get power, albeit less efficiently. Energy is lost through heat and noise, so you might hear a characteristic electrical hum once you’re plugged in.
You’re also at risk of overheating. If you’re opting for modified sine wave inverters, make sure everything is well ventilated.
5. Bonus Features
Optional extras such as hardwiring kits and remote controls can take your power inverter to the next level. A remote control will turn your inverter on or off without the need to access the device itself – particularly handy for bigger inverters that are hardwired, and often end up tucked away.
Wiring kits and lead cables are often bundled in with the inverter itself, saving you a trip to the hardware store.
6. Warranty
As with all electronic goods, the warranty is important for peace of mind. Twelve months is standard, but premium brands offer exceptional customer support and three years warranty on parts and labor, such as installation.
Be careful to read the fine print. Sometimes you can void a warranty by installing your inverter upside down, or even by opting for DIY installation. If your warranty requires professional install, it’s probably worth the punt.
Wrapping Up…
Without a car power inverter, you’re wasting a valuable source of power.
Your car battery could be doing a lot more for you! It should be charging your laptop on a road trip, keeping your kids entertained by the TV on a long drive, or even powering your coffee brew in the morning!
And the right power inverter gives you access to all that power and more.
You’ll be accelerating towards fully powered electronics in no time!
