How To Choose The Best Power Inverter For Car

While you are on a journey to figure out the best power inverter for your car, it is important that you should stay selective and evaluate the key aspects. Here, we made a list of some important aspects that you can look after and figure out some of the best products with ease. Let’s begin by checking out the most important aspects –

⇒ 1. Reputed Manufacturer

A well-liked manufacturer of power inverter feels way more reliable and easier to prefer over the other brands. The brand credibility ensures a great value for money deal, and you can expect better after-sale services in case of having any trouble with the product. This is the major reason that most of the people prefer reputed brands. This is the key factor we decided while making this list. The market is full of cheap quality products with no brand labeled on them, and choosing such a brand seems tricky as well as less authentic.

2. Number of ports

For normal use, everyone needs at least one socket option to plug-in their laptop charger or anything they want. If you are going for a brand that provides two ports, then you can expect a versatile use which will be fulfilling the need in an effective manner. Meanwhile, paying close attention to the USB ports can also help. Some brands provide two USB ports to directly charge your smartphone at higher voltage like 10v or more. There is nothing better than having USB ports and two plug-in sockets.

3. Power Supply

A good quality power inverter is capable of converting 150v DC power into 110v, and it is standard power supply required by most of the devices in America. Most products claim to provide such a good power supply, but are they truly offering such power. To check it, you can consider reviews mainly.

4. Compact and Lightweight

The weight is not a major issue, but if you get an inverter that feels compact and lesser in weight, you can expect better usability. There is nothing to worry about the power supply, and you can get better use for sure. Compact power inverters are easy to fit under your car seats, in the glove box area, or any other place you want. If you want to use it to charge your laptop or connect any other device, there will be no problem regarding the use, which can provide excellent value for the money you spent so far.

5. Warranty

Except for the fact that you are going for an affordable product, have you considered the warranty section? Does this product offer any specific warranty period? Or, do you know how god their after-sale services are? These are a few questions to consider because a good product always provides six months of warranty at least. A warranty period helps you expect better value for money, and if you find any issue in the first six months of purchase, you can easily claim. This is always an important factor, and you should not avoid it.

6. Budget

Deciding a good budget before the purchase of a power inverter is important. You can find a range of devices available from $30 to $300. You have to understand the need and use so that you can decide on a budget. Sticking to the budget will allow you to sort out the best products and not to get confused, which always help whenever you are shopping for uncertain devices like a power inverter.

7. Customer Feedback

When everything seems typical, and you feel confused about whether a product is durable or not, checking customer feedback can help. Considering the rating is not a great choice always, but reviews help to obtain details about durability, effective working, and other flaws also. You can ensure whether a power inverter will be compatible for your specific need or not. If feedbacks aren’t enough, then you can take suggestions from experts and learn whether a product is better to consider or not.

Car Power Inverter Using Dos and Don’ts

Below are some of the dos and don’ts associated with the usage of the car power inverter. You can check out the details and restrict your usage accordingly

Don’t Rely on Counterfeit Products

The first point to note is that there are many counterfeit products available in the market. You must not buy counterfeit car power inverters. Restrict your purchase to the authorized seller or the trusted online retailers only. You can never be sure about the local products, and you don’t know when they will give up. Bad quality car power inverters can also cause a fire because of overheating, and hence using counterfeit car power inverters is a strict No. You can choose the products from the list of offerings that we have provided, and they are all reliable.

Turn the Ignition On

The next thing to note is that you should not use car power inverters without turning the engine on for a long time. Restrict the usage of car power inverters without an engine for 30 minutes at max. After that, turn on the engine and continue to use the inverter. We say this because using the car power inverters without running the engine will drain off the battery, and you will not be able to restart your vehicle. In such a case, you would need to jump-start the car. Using the car power inverters for a long duration without firing up the engine will also be bad for the battery.

Correct the Wiring & Connections

Most of the car power inverters come with a cigarette lighter port connection. If your car power inverters use that port for connection, you can ignore this point, but if your car power inverters use jumper cables, you need to be assured about the connection polarity. You should connect the positive node to the positive terminal and the negative node to the negative terminal. Not connecting the jumper cables correctly could short the inverter, and in the absence of safety equipment, it can also damage your electrical appliance. So, take care of the connections and the fuse as well.

Restrict the Load

Many consumers overload the car power inverters, resulting in a blown-out fuse or a damaged battery. You should try not to exceed the load over 1000 watts. Using the hairdryer and the hot water bag can exert a lot of load on the car power inverters. Check the rating of the inverter and if possible, try to use only one appliance when you are using a high power appliance. Restricting the load will also help you maintain your battery’s health and avoid any damage to the internal circuit.

Adequate Ventilation

Car power inverters usually have MOSFET devices on the circuit, and they can get heated up during the usual usage. In such a case, you need to ensure adequate ventilation for the car power inverters. This will keep the inverter cool. If the inverter overheats, then there are chances that the circuit board may get damaged. To avoid all this, proper ventilation will also prolong the life of your car power inverters. If you place it on the foot mat, you can even turn the directional air conditioning to keep the device cool.

Car Power Inverter Frequently Asked Questions

Yes, as far as we know, people who use a 600-watts car power inverter are satisfied as they could use their laptop, printer, coffee maker, etc. on their car using this inverter. However, the maximum time these devices could run depends on the model of the device and their power consumption.

3. Does a car power inverter have to be hardwired directly to the car battery?

The power source connection of a car power inverter could vary based on the car power inverter itself. Most commonly, car power inverters with a power rating below 150-watts could be plugged into the cigarette lighter socket. Any car power inverter with a power rating above this should be hardwired to the car battery as a cigarette lighter socket might not be able to support such a power rating.

4. Is it possible to use portable refrigerators in my van if I use a power inverter?

It is not possible to answer this question without specific details. What type of van, specification of the battery, a model of the refrigerator, etc. however, in general terms, it will not be possible in regular automobiles. One of the reasons is that refrigerators require 3 to 4 times more than their rated power and to support such power demand, the power inverter should be efficient and powerful. Such powerful power inverters require large batteries if you are asking this question because you have seen refrigerators in luxurious vehicles. In luxurious vehicles, the capacity of the battery would be large or there could be a dedicated battery for such appliances. You must remember, automobile alternators could recharge the battery to a limited extend only. Too much power usage could damage the battery and the alternator.

5. Is it okay to use a car power inverter if the car engine is switched off?

Yes, it is okay to use power inverters when the car is switched off. However, if the power consumption should not exceed a specific limit. If the car battery falls below 11.5 volts, the engine ignition would not be possible. So, we recommend that you turn the engine on every 1 or 1.5 hours. Such a routine while using the power inverter could recharge the battery and prevent the voltage from dropping below 11.5.

Meanwhile, the selection part is always typical, and ensuring durability can confuse anyone. Due to this, our list of ten great power inverter for a car in 2020 is going to help in an effective manner.
