If you’re serious about boating, you need the best power inverter. Marine power inverters change the DC power from your boat battery into useful AC power. AC power is what allows most common appliances to function. You can plug in any appliance you choose and get it running when you have access to AC power. That’s anything from a blender to make drinks to a charger to charge your phone. You can even kick back and play Xbox if you want. And of course, it’s also handy for plugging in power tools or cooking equipment.

One of the big benefits to using a power inverter is the efficiency of it. While a generator could provide power, it’s harder to use. Generators run on fuel. They also produce exhaust. A power inverter is quick and clean. All it needs is your boat’s battery to run. Then you have access to high power for a long period of time. With an inverter and charger combo, you can power your boat and appliances for even longer.

You do need to make sure you selected the correct power inverter for your boat. Not every power inverter is compatible with every boat. Likewise, you need to make sure your power inverter can handle the appliances you’re plugging into it. More and bigger appliances require more power.

Things to Remember

Choosing the best power inverter depends heavily on what you plan to do on your boat. If all you need to do is charge your phone, then power output may not be your Chief concern. In that case, you may want to focus mainly on the price of the inverter. Any inverter will have a few factors you’re going to want to check out. Once you know how the inverter works and what it can do, you can make an informed choice.

Continuous Wattage

Arguably the most important thing to consider when buying a power inverter. When you know the continuous wattage, you know how many appliances the inverter can power. For instance, if you have a 2000-watt inverter, you know you can handle an 800-watt microwave. One thing to remember is that most inverters will not be able to offer you 100% efficiency. If it says 2,000 watts, expect it to max out at 1800 watts. Most inverters can only pull about 90% efficiency. Just to be safe, plan for that as your baseline.


Depending on what you want to do with your inverter, you’ll need to account for the outlets available. Some offer one, two, three or more AC outlets. Some will also feature USB charging ports. More outlets offer more versatility. But you have to remember your space concerns as well. How many appliances can you plug into the space you have available?


Inverters are sold as either modified or pure sine wave forms. Modified sine wave inverters are less expensive. Pure sine wave inverters are a more efficient power source. They can create more power and transfer more power. If you are using smaller electronics, a modified inverter will probably do the job for you. If you’re running some serious electronics, you’ll want a pure sine wave inverter. Pure sine wave inverters are able to handle large appliances. Think things like refrigerators and stoves.

Safety Features

An unprotected power inverter can fail you in a number of ways. There are up to six different levels of protection that you can get from certain power inverters. The more levels of protection, the better off you’ll be. These include:

  • Overload protection
  • Short circuit protection
  • Reverse polarity protection
  • Overheating protection
  • Under voltage protection
  • Over-voltage protection

Any one of these could cause serious damage with your electronics if something were to go wrong. An inverter that includes protection against these things will keep your devices secure.

Some inverters feature GFCI output. These are safer to use than typical AC outlets. They greatly reduce the risk of shocks. Remember, the amount of power flowing through and inverter can be dangerous. 120 volts could be dangerous, especially in wet conditions on a boat.


Even though this may not seem like a major concern, the case for your inverter is important. Not every inverter is meant for marine use. Tough aluminum cases resist corrosion. A power inverter that’s meant for an RV might not be able to handle extended use on the water. This is especially true if you’re using your boat on the ocean. The salt spray could potentially cause damage to a normal inverter.


It should come as no surprise that a power inverter can draw a lot of power. You need to make sure your batteries are up to the task. Many serious boaters will pair their inverter with a generator. That ensures you never run low on power. You can also get an engine alternator. That will recharge your battery while the engine is running. That way your inverter will not drain you dry. Also, many boaters opt to use solar panels. You can even get wind generators. Always make sure you are sure about how to handle this kind of wiring. If you’re not, get a professional to do it for you. Mistakes could leave you out on the water with no power at all.

The Bottom Line

A good power inverter can make boating life much more enjoyable. If you spend a lot of time on the water, you probably look at your boat the way people on land look at RVs. You need to have a reliable power source to operate your electronics. Whether that means running a microwave, or plugging in a computer, it makes things easier. Even keeping your phones charged can be a hassle sometimes. The best power inverter can make your boat almost as convenient as your home in terms of power usage.

Make sure you are buying an inverter that matches your needs. If you are planning on extensive hours of use, then you’ll need and more powerful inverter. If you just need to keep a few things charged, then a smaller unit may work for you. Stay safe and have fun, that’s what boating is supposed to be about.
