The 10 Best Power Inverters to Buy 2019

Reviews

Some of the best power inverters can prove life-saving while on the road. Transforming DC current in alternating current (AC) will provide the electricity needed to power devices such as mobile phones and tablets. Car, vans, and RVs can benefit from such a power inverter. The greatest part is that power inverters have such wide applicability.

It’s not just about charging smartphones as it can be about powering laptops, TV and even various electrical cookers. Having this power from the vehicle means travelers don’t need to rely as much on their location as they can still enjoy the comfort of their daily lives at home with all of these gadgets.

Features to Consider in Good Power Inverter

When it comes to purchasing a power inverter, there are a few basic characteristics to understand. First of all, not all power inverters have the same capacity. Secondly, there are two types of power inverters, regardless of their capacity.

Size
The size of a power inverter is mainly 1.000, 3.000 or 5.000 watts. Most of the power inverters available to purchase are somewhere in-between when it comes to power. The larger the devices which are being powered, the higher the wattage of the inverter should be. If a car power inverter can come with lower wattage, an RV power inverted might need to come with higher wattage to power larger electronics.

Modified sine wave
The modified sine wave power inverters offer just enough wattage for everyday electronics. They are also cheaper to manufacture and this is why they will be more affordable to purchase.

Pure sine wave
The pure sine wave power inverters have a higher power capacity. They are also compatible with almost all electronics. They can also work with multiple devices at the same time as a result of this extra power. Some of the following power inverters are best for the consumer looking to power everyday devices.

Guide to Buying the Best Power Inverters

There are so many great power inverters to choose from that the decision can seem complicated. Luckily, some of the best power inverters can work for different types of devices. But those who’ve never used a power inverter before can start applying tips below to make an informed purchase.

Maximum watt power
Maximum wattage is still one of the most important indicators of a power inverter. The good news is that most products are actually very powerful for what the users actually need. In fact, most users only charge their smartphones in their cars.

However, not all users are like this. It is users who need to charge all types of other devices who will start understanding wattage for what it really is. The balance of wattage and affordability sits just above the 2.000W mark. Some of the more powerful power inverters will actually be more expensive. At the same time, they will offer the most rewards when it comes to the overall sustainability of constant power, which is important, especially with large consumers such as power tools.

Wattage is not the only important characteristic, especially when not in line with constant power. The way the inverter manages to offer constant power is at least as important. In too many cases, even charging laptops can prove difficult due to power fluctuations. This is where even some users report display problems on their laptops during charging time, mainly due to this variable power.

Number of charging ports
The number of charging ports is now increasing on power inverters. However, not all of them are the same. Most power inverters mainly offer 2 or 3 outlets. Some of them may also come with USB ports. Having these two ports can prove important in today’s world where people have more and more gadgets.

The positioning of the ports is also important, as well as their number. This is why many users are simply unable to plug their favorite electronics due to the limiting positioning of the power inserts. One problem often seen in the space is with the positioning of the inverter itself, which can limit the access of to the power outlets. This is where smaller power inverters are reliable, especially in smaller cars where there is not too much space to work with.

Heat control and safety standards
Overheating used to be a big problem in the world of power inverters. The good news is that there are plenty of great designs to consider at the moment. Aluminum is now largely used instead of plastic, even on affordable power inverters. The material is known for its good capacity on heat management.

At the same time, cooling fans are important as well. Users have the ability to choose the products they want to use when it comes to heat management. But unfortunately, they might need to choose those with 2 or 3 fans, especially when connecting multiple devices at once. Without being overly cooling, extra fans can still do a better job at eliminating cold air from power inverters.

Digital displays
Digital displays are worth a discussion of their own. It is not necessary for a power inverter to come with a digital display. However, those which are able to offer such an integrated solution may make the lives of the user easier.
Most digital displays are similar in the type of information they offer. This can start with the actual battery voltage. But digital displays can also show information on high voltage or low voltage. Temperature can also be displayed for users to see. In most cases, the temperature is constantly displayed in graphic form.

But are these readings useful? Most of them can be useful. However, some of the readings might not actually have too much impact on the way the power inverter is used. Such an example can be seen with the temperature indicator. The best power inverters actually come with automatic shut off when the temperature gets too high. In fact, high temperature can be caused by multiple actions. However, having an automatic response system will actually protect the power inverters and all electronics connected to it.

Intended purpose
One of the often overlooked buying tips is to simply consider the purpose of the power inverter. The fewer devices it needs to power, the more compact the purchase can be. There is no point in investing in large power converters if that power is not actually going to be used. In fact, they might even be forgotten and not used at all due to their complicated setup.

On the other hand, those who want to get a bit more serious about the electronics, gadgets or tools they want to power may only go the route of large power inverters with multiple outlets. But the actual size of the power inverters can also be seen from a different perspective.

A larger power inverter is easier to connect directly to the battery via cables. Since there is plenty of free space to handle the cables, it can prove to be a quick operation But the good news is manufacturers also understand this. It is why some of the best power inverters made to connect directly to the battery are actually larger.

In terms of durability, a good tip is to purchase extended warranties when possible. Unlike TVs or smartphones, power inverters don’t actually get upgraded if they don’t break. They are made to last for years, at least in theory. Some users advice to purchase additional warranty coverage when possible. Most products are covered by an average warranty of 18 months. But this can be extended with some manufacturers.

Final considerations

The best power inverters can be useful for camping, long trips, weekends away and even at home. They transform the power from the battery in AC power which is suitable for all electronics. With difference power capacity, these power inverters are actually among the simplest and most efficient tools to consider. For many users, they represent a viable option to stay connected.
