EcoFlow Delta Pro - A Comprehensive Review 2024 | Wild Oak Trail

If you’re looking for a clean alternative energy source, then look no further. Even before the release date, the EcoFlow Delta Pro power station came with plenty of hype among avid outdoorsmen, construction workers, homesteaders, and even regular homeowners. Well, now is a great time to invest, considering the US is seeing record breaking power outages.

Fortunately, the model is now available to the public, but you may still have some questions about it. Here’s everything you need to know about the new Delta Pro!

How Does the EcoFlow Delta Pro Solar Generator Work?

Solar generators like the EcoFlow Delta Pro work by absorbing sunlight through various solar panels, converting the light into energy, and storing it in a battery. Once there, the power can last in the battery for up to a year, and you can plug nearly anything into it. The EcoFlow Delta Pro offers two USB-A ports, two USB-C ports, five AC outlets, and two DC5521 outlets, allowing you to charge most electronic devices.

All you need to do is plug in the MC4 cables between the solar panels and the generator for ongoing input, and plug anything you want into the generator for output. Remember, the panels will perform best with direct sunlight, even if there are clouds.

Not only that, but the device itself can connect to WiFi or BlueTooth, allowing you to monitor its performance through a handy app. While a lot of information is available on the device screen, the app offers valuable insights into energy consumption, battery life, which outlets are generating the most power, and more.

What Is It Used For?

Of course, a solar-powered generator is used for the same purposes as a gas generator, only they use different fuel sources and have different storage capacities. Solar generators are based around the idea that power is inconsistent, unlike gas generators, so they rely heavily on battery technology.

Consequently, the EcoFlow can be easily transported on the road, on the water, or anywhere you want, offering continuous output for the duration of its battery life, without the use of gas or diesel. There are no harmful emissions, no risk of carbon monoxide poisoning, and no flammable liquids involved.

Conversely, different people will have different uses for their generators, but the EcoFlow offers just about all of them, including:

  • Back-up power source for home appliances
  • Power for RV or boat
  • Outdoor/camping power source
  • Off-grid living
  • Construction
  • Safe backup for life-saving medical equipment
  • Green alternative to portable energy

The list goes on. No matter what your purpose is, this particular generator offers some amazing features, many of which a gas generator can’t compare. For example, the sun isn’t the only thing that can power it!

EcoFlow Delta Pro Solar Generator Performance

Since the EcoFlow Delta Pro release date passed, plenty of great information has become available from avid users of the generator. Energy ratings have shown that this model puts out energy with 93% efficiency, which is far ahead of other solar generators and leagues ahead of most gas generators.

For context, many big brands in the industry are trying hard to break the 80% efficiency threshold, making 93% an incredible feat.

While standard panels that come with this model offer 200 watts, you can upgrade to the 400-watt weather-proof panels that still pull in over 100 watts on the rainiest days!

EcoFlow vs Gas Generator

If you’re choosing between a gas generator or a Delta Pro, then let’s offer an objective look at the two and see how they compare. We already mentioned that a gas generator emits harmful or toxic chemicals, which means you can’t use it indoors. However, we’ll talk entirely about performance and price.


First, the gas generator is likely to be of a slightly lower initial price for the same amount of output as the Delta Pro. However, the operating costs make a world of difference.

Even if you manage to save a few dollars on the upfront costs, gas generators require constant trips to the gas station, costing between $3.50 and $4.60 an hour to run. That means that if you run it for 48 hours during a power outage or camping trip, you would spend between $172.80 and $220.80 for each extended use. With the Delta Pro, you won’t necessarily have to spend a dime.


Next, let’s talk about performance. The output on the Delta Pro is around 240 volts. The maximum running wattage is 3,600, which can last for hours, and the maximum surge is 7,000.

Well, plenty of gas generators can live up to that amount, and both can power most appliances in and around your home, including power washers, refrigerators, and even dryers. In terms of performance, the Delta Pro is very similar to most quality gas generators.

Lastly, gas generators only have one power source, and it relies entirely on it to continue running. Not only does the Delta Pro have long-lasting batteries, but it also has different charging options to choose from!

Different Charging Methods

The Delta Pro is known as the world’s fastest-charging portable power station, and it lives up to its reputation. So, how fast does it charge?

Obviously, a solar generator is powered by the sun, right? Well, yes, that’s one option.

However, the EcoFlow Delta Pro also allows you to charge from your car, through an AC charging input in your home, or even with electric vehicle (EV) charging.

Fortunately, there are currently over 46,000 EV charging stations throughout the US, most of which have fast charging capabilities. If you look for certain government charging stations, you are likely to find free power to charge your batteries up in the fastest amount of time. Charging this way should only take around 1.7 hours.

Another free option is to go with sunlight. Depending on how much direct sunlight you receive, you should expect your battery to fully charge (from zero) within 2.8 to 5.6 hours, which is some of the fastest in the industry.

Although, if you want to charge your Delta Pro in the car or at home, expect to fully charge it from zero in under 3 hours. Of course, doing it at home will cost some money on your electric bill, but it’s a great option to keep handy!

EcoFlow Delta Pro Battery Life

Once it’s fully charged, the standard Delta Pro can run a chainsaw for 3 hours at a time. If you’re in a storm, you can power your refrigerator for 24 hours. If you’re camping, you can charge a 10W speaker for 108 hours.

Now, if you have extra batteries or if your panels are plugged into your unit, you should expect these numbers to increase dramatically. Even with limited sunlight, an extra battery and attached panels could easily triple your usage.

Also, the model has a brand new LFP battery geared for over 6,500 cycles. Essentially, this means that you can use your generator daily for years before it ever reaches 50% of its original capacity, which is a major concern for most generators.

Lastly, this battery is perfectly safe for regular use in almost any environment, both indoor and outdoor. Temperature is a major concern for batteries, but not in this case. The Delta Pro is safe to use in temperatures from -40C (-40F) to 90C (194F), meaning it can handle your coldest winter or your hottest summer all the same.

How to Use the EcoFlow Delta Pro

When you purchase the system, you will receive a user manual in the box. However, the system itself is fairly intuitive and easy to use. Here are just a couple of suggestions to get the most out of your system.

Download the App

Your Delta Pro will have a display screen where you can monitor its charging, output, battery life, solar input, and more. However, you don’t have to be right there to read it.

By downloading the EcoFlow app, you can easily access this information from anywhere and see how well your generator is performing. Not only can you monitor, but you can control the entire system remotely, even while it’s powering your home.

This feature is especially helpful for powering appliances in another room, powering your camping fridge while you’re on a hike, or just monitoring performance during work!

Store Properly

Since the EcoFlow Delta Pro weighs around 99 pounds, we recommend storing it in a location where you can easily access or use it without having to lift it. Determine where it will get used the most and try to store it on an even surface nearby.

Now, the system comes with a convenient handle and wheels, so keeping it on the same floor where you intend to use it is great. 

Fortunately, there are no fire or safety hazards with the Delta Pro, even at full charge, so you can store it anywhere in your home, truck, or RV for safekeeping.

Maximize Efficiency

Of course, when using portable power, you don’t want to carry a lot of extra equipment with you or have to worry about finding a charger. 

If you’re doing a large project outside that requires power tools, then we recommend adding 200W solar panels to your system, as this will dramatically increase your battery life.

How to Purchase the EcoFlow Delta Pro

You can order the Delta Pro online with just the standard battery, but why limit yourself? Any bundle deal will help you save money and still come with free shipping and returns, so find the one that works for your needs.

Solar Panel Bundles

One of the greatest features of the EcoFlow Delta Pro is the solar panels that come with various bundles, especially with 200W.

The 100W panels are excellent for campers, as they can still passively generate power for your system with limited use.

However, the 200W panels can still generate significant solar power during a storm, making them ideal for home backup. If you’re working outside or you’ll need a lot of consistent power from your generator, we recommend the 1200W solar panel bundle for maximum power.

Additional Smart Battery

By purchasing an additional Smart Battery, you will effectively double your Delta Pro’s battery life. Remember, each battery can power a refrigerator for a full day, so doubling your capacity and using the right panels could help you prepare for even the worst storm.

Moreover, the batteries can easily connect to your system with one cable, and you can still charge both with your solar panels or other charging methods.

Smart Home Panel

Lastly, if you intend to use your system for home backup, then we suggest using the Smart Home Panel. This can attach to your home system for backup power throughout your entire home, using your Delta Pro battery as backup power with a switchover time of under 20 milliseconds!

Is the EcoFlow Delta Pro Worth It?

All in all, the EcoFlow Delta Pro is a game-changer in the industry, and it’s one of the best clean alternatives to backup energy on the market. The model puts out roughly twice the amount of energy as comparable power stations of the same weight and price.

With the long-lasting Delta Pro battery, the fast charging time, the incredible output, and the many charging options, it’s hard to compete with this model. This only leaves one final question.

EcoFlow Delta Pro Price

Finally, let’s answer the one question that’s been on your mind: what does this all cost? Well, the newest and most advanced addition to the solar generator industry starts at $3599 and goes up depending on the package of your choice. In all honesty, you get what you pay for.

Moreover, there are no other green alternatives to gas-powered generators that offer the same benefits. Again, even if you find a gas-powered generator for a lesser price, you will bridge that gap within only a few days of use with ongoing fuel costs.

The Verdict
