    If you’re looking to bring a multi-functioning piece of equipment onto your boat, you may want to consider the Soyond portable solar generator. Beyond its four-in-one USB cable for charging phones, this generator’s compact, vertical design incorporates a light on one side, which we found is rather bright and can be useful for fishing. It has two additional three-watt LED lamps, along with a three-watt output to those lamps.

    The Soyond also offers an FM radio, Bluetooth-compatible speakers ,and a TF card slot to play stored music. We discovered that the speakers deliver moderate to good quality sound. Other features on this unique generator include a digital LED display, power switches, and charging and power indicators.

    With an incorporated handle, this lightweight 4.4-pound generator can easy come along on your outings on the water. Plus, when you’re far from shore, you can use the included six-watt solar panel kit to recharge the 800mAH capacity backup lithium battery. Otherwise, recharge the battery using the included adapter in a 110-volt wall socket or a car charger.

    Be aware that we could not determine if the power output incorporates safe sine wave output.

    6. AIPER Portable Power Station

    AIPER Portable Power Station

    Small enough to balance in the palm of one hand, you’ll be able to easily take the AIPER Portable Power Station on your next outing on the water. This lightweight generator can power any small appliance, such as a fan or a light, that requires less than 150 watts. It can easily recharge your phone or laptop. However, we could not be certain that this product offers clean and safe sine wave output.

    This generator offers one 110-volt AC outlet, which supplies a continuous 150 watts with a surge of 200 watts, and two smart USB-A ports and two DC ports. For your convenience, an LCD display shows you the status of each port and outlet. Additionally, this generator has a built-in flashlight which can come in handy on your boat.

    The lithium battery can be recharged using three different methods. Before you leave the dock, recharge it from a wall socket using the included AC wall charger or from your vehicle using the included car charger. Once you’re on the water, you have the option of recharging using a compatible solar panel — that is sold separately.

    • Small and lightweight
    • Built-in flashlight
    • Various outlets and ports
    • Three recharging methods
    • Solar panel not included
    • May not have sine wave output

    Buyer’s Guide

    Before you make a purchase, consider a few factors. Using a portable generator on the water may require that you marinize it. Make sure to research all the steps you need to do in order to make sure your portable generator is ready for use on the water.

    Also, while many of the portable generators on the list are small and lightweight, if you’re purchasing a larger model, take a moment to consider whether you have adequate space and that the weight isn’t too heavy. While smaller portable generators may not supply a great deal of power, they are convenient for finding a safe place for storage and use on your boat.

    Finally, if you choose a gas-fueled portable generator, be sure to follow the same safety procedures that you would on dry land. Make sure you bring enough fuel, and if you purchase a portable generator with a rechargeable battery, fully charge it before leaving the dock. Solar panels, which may or may not be included at purchase, are useful when you’re far from shore, but only if you have ample sunlight and are willing to wait the hours it takes to recharge your generator’s battery.

It offers multiple options for recharging its built-in battery and includes a car adapter.

    Finally, the A-iPower SUA2000iV Portable Inverter Generator took our third place on our list as our premium choice. With an impressive 2,000 peak watts and lengthy extended running time, this gas-fueled portable generator offers rather quiet operation and an inverter for clean output.
