How to Buy the Best Car Power Inverters

How To Buy The Best Car Power Inverters
How To Buy The Best Car Power Inverters

Car power inverters are unique devices with distinctive technologies, making it necessary that you learn at least, a little about them, so you can understand their different features and what these actually mean.

It's this understanding that'll offer you enough information to make an informed decision when choosing an power inverter for your car.

Following is a listing of these important factors.

1. Output Power

This refers to the total amount of power that the power inverter can deliver, and from this figure, you'll also know the types of devices and how many of them that it can power at a time.

To get the best car power inverter with the right output power requires that you think about your purpose for the power inverter first because it's easy to calculate the total power consumption of all the devices that you'll be using.

Just look behind them and you'll see the watts figure. You may also want to add an extra 20% or more of power to the figure that you calculated because you never know when you might need more power.

Another very important consideration is 'starting power', which is the amount of power that devices with induction motors need only when starting. This is often many times more power than what they need to run continuously.

If you have such devices, then it's important that you consider a larger power inverter. These devices include fans, fridges, and air conditioners.

2. Number of Outlets

Outlets are another important deciding factor. You want an power inverter that offers you as many options as possible, and this usually means multiple outlets.

Most car power inverters out there will offer you two or more AC outlets, which is great, although some will only offer a single AC outlet.

Another feature is USB ports. Some power inverters offer USB ports for charging mobile devices and other similar items, although USB is D/C power and doesn't need an power inverter to produce from a car.

3. Cables & Accessories

Some car power inverters work from cigarette lighters, while others need a direct connection to the battery or the fuse box. Yet, there are those that come with more than a pair of cables, so you can either attach them to the battery or the cigarette lighter, as is necessary.

The choice here is left for you to make based on your power needs and availability. If you need about 100-300 Watts of power, then most cars will do okay and most cigarette lighter sockets can deliver the power.

Check with your vehicle first though, because many cigarette adapters get fused at 10 Amps, which means they will deliver a top power of 120 Watts. Even with a 20-Amp fuse, you'll get about 240 Watts of power.

This means that you need a real wire connection to the fuse box or battery for higher powered uses, and even then, you still need to make sure that your vehicle's alternator can deliver the needed level of power, else you'll be draining your battery really fast.

4. Construction

You need an power inverter housing that's well made to protect the components inside, so they can last longer. This may mean focusing only on power inverters with steel construction.

For the connection cables, you want them as thick as possible, because the thicker they are, the more power they can handle, and the longer they'll last.

5. Ease of Use

Obviously, you want an power inverter that's easy to set up and to use when you want. A simple design with a clean interface is best, and it should come with everything you need for a quick setup.

6. Safety Features

Power inverters work with dangerous voltage levels and often heat up during operation. It's, therefore, necessary that a good device comes with important safety features to keep itself and its users safe.

Such features include a fan for cooling the components, an LCD monitor for displaying warnings, or surge and short-circuit protection.

7. Warranty

You want the best value for your money, so you need a good product that will serve you well. One way to check out a product's quality is to check out its warranty. In simple terms, you want a car power inverter with a warranty that's as long as possible.

Conclusion

We've come to the end of this car power inverters review and you've seen all the different and impressive offers in the market, including the powerful, the nicely designed, and those with the longest warranties.

Since it's impossible to have a single best car power inverter because we all have different needs, it's left for you, therefore, to make your choice, based on which of these power inverters best meets your needs.
