Have you been scratching your head trying to think of ways to make your van more liveable?
We’ve been there. While the idea of living out of your van can conjure images of idyllic travel and feelings of ultimate freedom. However, in reality, the inconveniences of van living can sometimes overshadow the thrill of adventure.
One of the biggest challenges of van life is not being able to power your electronics effectively.
Picture the scene: you’re on a road trip in the middle of nowhere, and your phone, for whatever reason, decides to stop working entirely. You don’t have built-in satellite navigation, and without your phone, you’re completely lost.
If only you had some way to charge your laptop! That way, you could drive to the nearest wifi hotspot and find your way from there. Unfortunately, though, there’s no way of charging sensitive electronics like laptops directly from your battery, so you’re stumped.
Unless, of course, you have an inverter installed.
A 400-watt inverter is a perfect solution to most appliance-related van-living woes. At 400 watts, you can power a variety of appliances, including sensitive electronics, refrigerators, and even some portable air conditioners!

Best 400 Watt Inverter for Van Buyer’s Guide
Can’t wait to get your hands on your new 400-watt van inverter? You don’t have to wait long!
Before you make your final decision, though, take a moment to read through this buyer’s guide for helpful tips on choosing the best 400-watt inverter for vans!
Peak Power Rating vs. Continuous Power
First of all, we’d like to get a common point of confusion out of the way. Inverters typically come with a peak power rating as well as a continuous running rating. It’s important not to confuse these two ratings because they are indicative of very different things.
The continuous running rating of an inverter is the main thing you want to look at. This is the wattage that the unit will be able to put out on a consistent basis. Since we’re looking specifically for 400-watt inverters today, all inverters on our list are rated at 400 running watts.
The peak power rating, on the other hand, is the absolute maximum output the machine is capable of before failure. This rating should not be looked at as the maximum load the unit can take but rather as an indication that the unit can handle appliances that require more power for start-up.
Pure vs. Modified Sine
Once your power ratings are established, you’ll also need to think about the type of electrical power you want to work with.
For clarity, power type is defined by sine waves. Inverters can either deliver pure sine waves or modified sine waves.
Now, pure sine waves have a few very clear benefits. For one thing, the power delivered is cleaner, which means it’s safe for use with sensitive electronics such as tablets and gaming consoles.
Pure sine waves are also more efficient, so you can expect a higher DC to AC conversion rate through these models. This, in turn, leads to greater cost-effectiveness over time.
However, if you’re looking to save money and don’t have any ultra-sensitive electronics to power, a modified sine inverter will be the more cost-effective option upfront.
Being aware of which outlets an inverter has to offer is vital when making this kind of purchase. You need to know which power outlets are built into the unit in order to ensure it will be suitable for the appliances or electronics you want to run.
Generally speaking, we’d recommend an inverter with both household and USB ports. This way, you always have outlets for AC and DC charging. Be sure to check the rating on the AC outlets, however, since these can vary between 110 and 120 volts on 400-watt inverters.
A cigarette lighter port is also a useful outlet to have on an inverter because it allows for the charging of appliances using adaptors for even more flexibility.
Even lower-powered inverters, like 400-watt models, electrical safety should be taken very seriously. That’s why we recommend prioritizing inverters that come with built-in protection against overload, under-voltage, over-voltage, short-circuit, and overheating at the very minimum.
Overheating is usually prevented by the use of a fan. If you want to be extra-safe in this respect, there are smart fan systems that put out ventilation according to the current operating status.
Other useful safety features are visual displays and LED indicators for visual monitoring and alarms to get your attention if anything goes wrong.
We’ve talked a lot about the important internal features in 400-watt van inverters, but it’s also important to pay attention to the way the exterior of the unit is constructed.
Because your inverter will be installed inside a moving vehicle, it’s crucial that the unit should be able to withstand the odd knock or bump here and there.
An external aluminum construction is probably your best bet where durability is concerned. However, a strong ABS shell should do the trick as long as you don’t plan on throwing your inverter around too much – which we hope you don’t!
Additionally, it helps if your inverter is lightweight and compact to make it more portable. A portable inverter will be more multifunctional because you’ll be able to transport it between locations for a wider variety of uses.
