Car Power Inverter – A Buyer’s Guide

There are a number of factors to consider when buying a power inverter for your car, let’s look at some of them now.

Types of Car Power Inverters

First, you should be clear of the types of inverter available so that you can choose the correct one for your needs. They are as follows:

1. Single Outlet Inverter

The single outlet inverter is simple to use and provides a current of 150 to 300 watts. You can connect only one device at a time with a single outlet, and the design of the unit is normally small and portable.

They are one of the most affordable types of inverter, and in most cases come with very few features.

2. Multiple Outlet Inverter

Because these units have multiple outlets you can connect more than one device at a time. The design is bulkier as a result, and you should expect to pay more for one of these than a single outlet inverter.

The fact they have a higher current capacity to function, multiple outlet inverters will have built-in features to reduce the chance of overload.

3. USB Outlet Inverter

USB outlet inverters are a great way to charge and use USB-compatible devices such as tablets, smartphones, and mp3 players.

Because they are designed for small power draw gadgets, a USB inverter is no use for larger, energy-intensive items.

Car Power Inverter Pricing

Here are some examples of the price points for car power inverters, so you have a better understanding of what your money can buy.

Under $20

This low budget range will generally include the simplest USB inverters and very basic single outlet units. Essentially, low capacity power inverters, you can expect to draw 100 to 200 watts at most.

$20-$50

This is the budget that caters to most uses. You will get a higher-capacity of 250 watts and above with inverters in this range. This also includes multiple outlet inverters.

As these are often larger, more power-intensive inverters, they will have durable construction and may even include features such as cooling fans and overload trip switches.

Over $50

This will cover the top of the range power inverters, with some of the more expensive ones providing continuous power capacity of 1,000 watts and above.

These will have multiple outlets and will be able to charge power-intensive tools. Features such as cooling fans, LCD screen for status reports, and other safety measures will be included.

What to look for when buying a car power inverter

Now that we have discussed the types of inverter available and the price points you can expect to pay, let’s take a look at some of the specifications and features you pay attention to when choosing a new car power inverter.

Wattage

This is the all-important specification that will determine whether the inverter you choose is up to your needs.

n other words, the wattage capacity will directly impact the types of devices you can connect to the inverter.
For example, if you only need to charge a few small electronic devices, a USB or single outlet inverter providing 150 to 300 watts will do the job.

Conversely, if you want to use large appliances such as a portable fridge or television while camping, you will require a multiple outlet inverter capable of 1,000 watts or above.

Example Wattage Draw

Before purchasing an inverter for your car, it is a good idea to quickly add up the wattage draw of the devices and appliances that you intend to use.

Here are some common examples:

  • LCD TV/Display: 120 watts
  • Smartphone Charger: 20 watts
  • Coffee maker: 350 watts
  • Laptop Computer: 100 watts

Adding this all up, we can see that an inverter capable of 600w draw would suffice. If you tried to power all four of these at the same time on a 500w unit, you could run into problems.

Outlets

We have already covered this, however, you do need to think about the number of devices you want to connect at any one time.

Yes, single outlet inverters are cheaper, however, at times you want to power more than one device simultaneously, you may regret going for the low budget option.

Consider your needs, and how many outlets you will require.

Size and Weight

Smaller, more portable inverters are really the way forward. No one wants a bulky unit taking up space in their car, (it is a bit different with an RV as it is easier to slot a large inverter out of the way).

Thankfully, even multiple outlet units with lots of features, have streamlined designs that are portable.

Sine Waves

The majority of inverters available today have sine waves that are either modified or pure sine waves. The specifications should tell you this.

It is an important distinction, because inverters that provide irregular waveforms like jagged square waveforms (as older models once did), can risk damaging your electronics.

Modified sine waves create less stress on devices, with pure sine waves being even safer and more efficient.

General Features

Features such as an LCD screen with status alerts and updates, soft-start technology that puts less strain on your car battery, and automatic low-battery shutdown are all great attributes.

Generally and understandably, the more features an inverter has, the higher the price point.

When looking at the specifications and features it is often a juggling act of what you really need, and what you are willing to pay.

Safety Certification

An ETL stamp is always a good sign that the inverter in question is safe and has been thoroughly tested.

The stamp means that the inverter meets all North American safety guidelines. The features included in the unit are there to protect against overloading and overheating, as well as shorting out and other faults that can occur when connecting and powering electrical devices.

Benefits of Owning a Power Inverter

beach car power inverter

The benefits of owning a car power inverter are pretty clear. When out on the road, you have access to power to run your devices and appliances.

It allows you to enjoy outdoor activities without stressing about where and how you can power the devices you are using.

Camping and traveling can be made a whole lot more fun, with a quality, multiple outlet inverter.

If you need to run some power tools away from an electrical wall outlet, the right car inverter can provide the means.

Furthermore, car power inverters obtain that power from your vehicle. Extended your supply needs much more than standard device battery power.

And you never know, should you be stuck somewhere and it is an emergency situation, an inverter could provide power to something that might just save the day.

Car Power Inverter FAQs

faq

Q: How do I hook up a car power inverter?

How you install the inverter is dependent on the size of the unit and its power capacity.

Small single outlet or USB power inverters can often be connected directly to your cigarette lighter. However, the limit here is no more than 200 watts.

For medium, to large inverters, you will need to connect the unit directly to the cat battery using the clips provided. These are clearly marked positive and negative and should not pose a problem to most people.

Q. Can I use a power inverter on an old vehicle?

Yes, you can use a new power inverter on an old vehicle. The main problem would be if the car battery is old and might run flat quickly.

With this in mind, you should always disconnect the inverter from an old vehicle once you have switched the engine off. This will reduce the chances of the battery running dry.

Q: What do peak and continuous power output mean?

Peak power output is the level of watts the inverter can provide for a window of time. It basically means the highest you can draw at any one point with all connected devices running at full power.

Continuous output refers to the average wattage the inverter will provide under normal, continuing circumstances.

Q. Does the engine need to be running for me to use a power inverter

Yes, the engine should be running the engine before you start using the inverter. On new cars with a reliable battery you can use the inverter for a short while without the engine running, but for no more than an hour, and even less if powering energy-intensive appliances.

As mentioned above, older cars should be running the entire time, and you will need to disconnect the inverter after use.
