5 Best Outdoor Generators for Spring in 2024 Reviewed

There are many outdoor generator options, but the best choices for spring are portable and run on clean, renewable solar energy.

Traditional fossil fuel generators are bulky and often have to be hauled by car, limiting options for springtime activities. Not to mention that they run on fossil fuels, are exceedingly loud, and produce toxic emissions.

Portable solar generators provide the most value and benefits with the fewest drawbacks. 

Unlike propane or gas generators, solar generators are quiet and use clean, renewable energy. They’re perfect for almost any off-grid application — from backpacking to powering your whole home.

Whether camping, backpacking, or backing up your essential appliances at home, a reliable power source is crucial. 

Outdoor solar generators upgrade you from camping to glamping, keep all your personal devices charged, power your appliances, and more.

Here are our picks for the top five solar generators you should consider this spring.

What to Consider When Buying an Outdoor Generator for Spring

Understanding the specs of a quality solar generator will help you make an informed buying decision and ensure you get what you want from your outdoor power supply. 

Before you purchase any solar generator for spring, here’s what you need to know.

Storage (Battery) Capacity

Your storage capacity (wH/kWh) determines how much electricity is available for your appliances before recharging. More battery capacity means you can power more devices for a longer time. 

Storage capacity can impact your recharge times. A battery with higher storage capacity tends to take longer to charge using solar panels. That’s not because the battery is charging more slowly — it simply means that it takes longer to charge 100% because it stores more electricity. 

However, if you want to run multiple high-wattage appliances for extended periods between charges, a high-capacity generator is your best choice.

AC Output and Surge Power (Starting Watts)

The AC output determines the maximum amount of electricity (W/kW) a solar generator can deliver at once. For example, if you want to run a refrigerator with an operating wattage of 700W, the minimum AC output of your solar generator must be 700W or higher.

It’s crucial to note that many appliances require more electricity to start up than they do to operate. Using a 700W fridge as an example, it will constantly consume 700W while operating but may need 2200W of starting watts (surge power) to start.

All of EcoFlow’s portable power stations and solar generators offer proprietary X-Boost technology. X-Boost provides a short burst of additional electricity to get high-wattage appliances up and running.  

For example, the DELTA 2 provides 1800W of running watts and 2700W of starting watts. It can get that fridge up and running with no issues.

It’s also crucial to keep in mind that AC output measures the total running wattage a generator can deliver. With 1800W of operating power, the DELTA 2 can power multiple devices simultaneously until their combined running wattage exceeds 1800W.

Being realistic about how many appliances you want to run at once is crucial. For example, the DELTA 2 can handle running most fridges and air fryers simultaneously. But if you want to add a microwave and lighting into the mix, you’ll probably need to look for a solar generator with more AC Output capacity — like the DELTA Pro

Appliance and Device Wattage

Make sure you know what kinds of appliances you will be charging with your generator and how much power they require to work. The wattage should give you an idea of which type of generator you need and is an excellent place to start when shopping.

For example, are you only looking to charge small devices such as a phone or laptop? You can get away with any generator with these needs. Something like the River 2 + 110W Portable Solar Panel will be more than sufficient. 

That said, you’ll need higher storage and power output capacity if you want to power multiple high-wattage appliances at the same time.

Fuel Type

Outdoor generators use various energy sources, from gasoline and propane to solar and wind. The best fuel type for you depends on your level of electricity consumption and your use case.

Some options, like gas generators, require strict safety measures because they produce toxic emissions. If you’re using one at home, you can’t use it indoors, and it must be installed at least 20 feet away from the house. 

The good news is that all the outdoor generators reviewed here rely on battery storage and can charge solar panels, AC electricity, a car adapter, and USB-C. 

Solar generators produce no toxic emissions or greenhouse gases — they’re whisper quiet too.  

Portability, Weight, and Size

Portability is vital if you’re looking to take a generator on the move. Look for lightweight, compact solar generators like the River 2 — especially if you only need to power your personal devices.

If space is an issue, foldable or collapsible solar panels are ideal. They don’t take up much room, and EcoFlow’s portable solar panels even come with a handy carrying case.

If portability isn’t high on your list of requirements, focus on power output and storage rather than size or weight. Aside from loading it onboard for an RV trip, you might not have to move the generator much (or at all!). If that’s the case, a larger solar generator capable of running high-wattage appliances is more versatile, especially for extended trips.

Charging Time

If you’re constantly on the go and don’t have much time to wait for a generator to charge, pay close attention to available charging options and speed. 

EcoFlow’s solar generators offer industry-leading charge times — up to 5x faster than other manufacturers.  All of the RIVER 2 series charge from 0-100 in around 60 minutes and can fully charge using solar panels in 3+ hours of peak sunlight.

Noise Levels

Noise isn’t a concern for everyone, but it probably will be if you travel in an RV or camp. Campgrounds typically have a curfew for generators that exceed 60 decibels because of excessive noise and may face other restrictions.

The average gas generator produces 80-100 decibels (dB) of noise — comparable to the “inside of an airplane or an approaching subway train.”

On the other hand, solar generators are virtually silent — and you can operate them indoors!

Final Thoughts

Spring is the season to venture outside and enjoy your favourite activities in the sunshine. 

Make this spring the best one yet with enough power for all your essential appliances, devices, and equipment, whether you’re planning a road trip or a backyard staycation.

EcoFlow has the right solar generator for whatever your off-grid electricity needs may be. 

Whether you’re camping, backpacking, RVing, staying at home to work on DIY projects, or transforming your shed into an off-grid abode, you have choices with EcoFlow.
