Buyer’s Guide

It is always recommended never to select any product based on the number of positive reviews. It might get you the best product but not always. Therefore, it is necessary to make sure that the product you are buying has all the available features that you need.

So, here in this section, we are going to focus on those things or features that you must look at before purchasing the best portable generator for a boat.

Power Output

First, it is necessary to find out what you will power on your boat? If there are only small things like bulbs, lights, laptops, smartphones, hairdryers, and other small devices, then a small portable inverter generator with 1600 to 1800 rated watts power output is enough. But if you want to power an air conditioner, microwave, or a fridge along with these small appliances or electronics, then you have to look for a unit that can at least produce more than 2500 rated watts.

So, it all depends on your needs and the purpose and duration of your boat trips.

To make things easier for you, first, write the names of those appliances and electronics that you mostly use during boating. Write their watts in front of them and then add watts to find the total required power to get a unit that can easily handle that power. Also, make sure that your generator has the correct outlets according to the devices you have.

Tank Capacity and Runtime

Tank capacity and runtime also need to be considered as they are very important factors. For longer boat trips, you must have to buy a generator with more tank capacity so that it can offer you longer runtime. And for short trips, you can go for the 1-gallon fuel tank to get more than 6 hours of runtime in most cases.

But here one thing you must keep in mind that runtime changes according to the load applied. Also, smart throttle systems are there in many portable generators that maximize fuel efficiency.

Parallel Capability

It is also necessary to make sure that your generator is parallel capable. In order to generate more power output on your boat, you can take help of this parallel capability to link another generator of the same generation or series.

Sound Level

Although the sound level is not an important factor to consider as you are not going to disturb your neighbors during a boat ride. But for your own mental relaxation, you must have to check the noise level of your generator. A unit having the noiseless operation is an ideal machine to go with on your boat trips.


First of all, your generator must have a low oil shutoff sensor. Also, overload protection is a plus. Other than this, if you have an emergency stop button installed to your generator, then it is good; otherwise, you should buy an emergency stop button kit separately. Also, make sure that the power outlets on the control panel are all GFCI protected.


The last thing that you have to check is the warranty offered by a company. Some units come with a warranty of 3 years whereas some companies only offer a 1-year warranty. So, make sure that you are buying a unit that is backed by a 3-year warranty.
