Waking up with 5 mins to spare before office starts is a hectic race a lot of us go through quite regularly. However, while trying to win at the race, we often forget that we were up watching YouTube videos all night, and our phones are now probably below 10%.

But car chargers are available, right? They are, but the problem with car chargers is they’re usually extremely slow and don’t give you any flexibility. This is where you need the best car power inverter, this will help you not only to charge up your phone, but you’ll also be able to do so much more.

Best Car Power Inverter : Ultimate Buying Guide

Whenever you’re dealing with an application that has a direct relation to your car, it’s wise to have a look at it beforehand. This ensures you don’t buy something that indirectly harms your expensive car.

To ensure you don’t make a mistake while buying a car inverter, we’ve taken the liberty to draw up a list of things to consider before buying.

Power Output:

This is a crucial issue that requires to be dealt with before you buy your device. Inverters come in a wide number of variants, which are mostly divided according to their output size. Ranging from 150W to 2500W, you’ll have to choose according to what you’ll be running off your battery.

If you’re thinking about running quite a few appliances of your inverter, then buying one with high wattage is necessary. On the other hand, if you’re only buying this for charging your phones and electronics on your way to work, then a small wattage should do just fine.

Price:

We tend to discard things when they’re priced less. An understanding that’s carved into people’s minds is that the more expensive a product, the better it’s quality. This doesn’t fall true when we’re considering car inverters.

A compact inverter priced below $50 that has the wattage you need will be easily able to do the job — giving you better quality services than some inverters that you might purchase for more than $100.

Plugin Methods:

Connecting your car inverter to the battery is a hassle on its own. The cigarette lighter ports provided in your car is designed to give out only a limited level of power. This is usually enough for smaller inverters; however, if you’re considering running big appliances, you’ll have to connect it to your battery directly.

If you plan to run a more significant appliance, then you’ll need an inverter that has the connection terminals included. Make sure you’re also getting alligator clips included in the box.

Number of Outlets:

This is a more personalized requirement; this will depend on the number of devices you plan on using at a time. If you’re the type of person that travels with your friends and your family, then having those extra ports on hand is always a blessing.

As you go upwards on the power line, the number of outlets tends to increase. This might cause the device to look bulkier and make it a hassle to carry around. If you’re not into a large number of ports but more into power, then a look at the compact line should satisfy your needs.

Cooling System:

Conventional inverters, in general, tend to get extremely hot as you’re dealing with high voltage output. Now consider that the same voltage-transfer takes place through a compact box. The heat in the inverter is enough to fry out the circuitry and, even in dire cases, cause fires.

Cooling fans become a necessity when choosing your power inverter as they ensure safety for not only your devices but you as well. We’d recommend you go for an inverter that includes a smart, silent cooling system. These don’t make noise and increase the speed with increasing loads.

Safety Devices:

While buying any electrical equipment, it’s at utmost importance that you make sure of the fail switches are included in the product. This applies to inverters, as well. However, a simple fuse does not cut; other more technical fail-safes are recommended.

Fuses are a must; having them built into the cigarette lighter plug is an additional safety measure you might want to consider. Next, you should look into technical safety features such as low/high voltage shut off switches, overheating protection, short circuit protection, and overload protection.

Digital Display:

This isn’t something that you must have, however having this makes life easier. A digital display is quite simply an LCD panel that gives a constant reading of the voltage levels that are currently present in your battery. It also gives you reading of the amount of voltage being drained out by the devices attached.

This is an important feature as it prevents you from draining out your car battery so that you don’t find yourself stranded on a campsite having to call AAA because your phone was low on charge.

Build Quality:

Some inverters come in a very simplistic form factor, so you can easily tuck them underneath your seats out of sight. Whereas others are there for the show, these are meant to be placed right on the dashboard.

These great designs are usually built up with a metal outer shell. The metal outer shell is not only great for the show but also provides durability that helps keep the insides secure.

Frequently Asked Questions About Car Power Inverter

Q1. Can I plug in an extension cord into the power inverter?
Answer: Technically this is possible. However, it would not be recommended. There’s a limit to the number of devices you can connect. Going beyond that limit might only damage your inverter or, worse, your battery.

Q2. What type of surface should it ideally be mounted on?
Answer: You can mount your power inverter on any form of surface. It wouldn’t cause a difference. However, you must make sure of certain factors such as the surface should not have easy exposure to water, it shouldn’t be mounted near a heat source or any place where it could easily get stomped on.

Q3. Should the vehicle be running while I am charging my devices?
Answer: Car batteries don’t hold much charge in them, the alternator in the car keeps resupplying power to the battery. So, unless you want your battery to die out on you, it is recommended you keep the car idling.

Q4. How much output can be achieved through the cigarette lighter?
Answer: Most of these inverters come with a maximum 85-87% efficiency rate. That being said, most ports have a 15A fuse included, so you’re able to drive out loads ranging from 120-150 Watts.

Q5. Are the fuses replaceable?
Answer: This is something that varies from company to company; most companies give fuses that are easily replaceable with easy-open caps. However, there are some on which the fuses are built-in, replacing the fuse from those that may turn out into a challenge.
