These are just some of your considerations. This buyer’s guide will inform your decision so that you can select the best portable generator for a boat with ease.​

1. Honda EU2000 Portable Inverter Generator Model EU2000T1A1

Let’s look at the Honda EU2000. We know Honda is a solid brand, and it lives up to it’s reputation as a generator for a boat. It operates at a very low volume, so you won’t be distracted by a noisy unit while you are trying to enjoy the ocean breeze.

It’s lightweight and compact, an important thing to look for when you choose the best portable generator for a boat for you.

2. Briggs & Stratton 30651 P2200 Portable Inverter Generator

Now let’s turn our attention to the fuel efficient, quiet OHV engine of the Briggs and Stratton 30651 P2200. Unlike many other generators for boats, the power this unit produces is safe to use with laptops, game systems and TVs.

The large one gallon fuel tank keeps this unit running for up to eight hours of non stop operation at twenty five percent load -a convenient feature you’ll want on your boat. Meanwhile, a USB port allows you to charge portable electronics so you can stay connected even on the water. The operating volume weighs in at 59 dB which is quieter than a normal conversation.

This Yamaha puts the “packed” into compact. It weighs less than 45 pounds making storage and transport a snap, but many amenities are packed into the generator too.

It has a feature called “Smart Throttle,” which allows for more fuel efficiency and the reduction of noise. The generator will run up to ten and a half hours on a tank of gas at ¼ rated load. Finally, the generator is very quiet at 51.5 dBA so you can converse with your friends as you enjoy your boat ride with no problem.
