EcoFlow DELTA Pro Performance

When it comes to portable power stations, the EcoFlow DELTA Pro is a top contender. But what sets it apart from other options on the market? In this section, we’ll dive into its performance and usability based on real-world usage.

Real-World Performance

The EcoFlow DELTA Pro is an excellent power source in various scenarios, including camping trips, outdoor events, job sites and emergencies.

The EcoFlow DELTA Pro boasts a 3600Wh capacity, and is capable of supplying up to 2000W of continuous power. This makes it suitable for powering multiple devices simultaneously or larger appliances such as refrigerators, power tools and even washing machines and clothes dryers.

In terms of charging speed, the EcoFlow DELTA Pro can be topped off in just two hours when using a wall outlet and four to five hours with solar panels (sold separately). This is significantly faster than other portable power stations on the market today.

The user interface is intuitive and easy to navigate, and the LCD screen displays all the essential information such as battery level, input/output power and remaining run time. Pairing it with the app expands the information you can keep tabs on and also gives you lots of power management options such as managing the charging rate if you’re using a lower-amperage circuit that might trip if too much power is drawn.

Furthermore, the EcoFlow DELTA Pro is equipped with multiple ports for charging various devices simultaneously. It also has a built-in AC inverter that can power up to 13 devices at once—though some devices may receive less power if the total draw is more than the maximum output.

Home Grid Backup

One unique feature of the DELTA Pro compared to other battery generators is its capabilities as a home backup power source. The unit is designed to be able to connect directly to your home’s breaker box with sold-separate hardware and professional installation. EcoFlow’s Smart Home Panel lets you switch easily from grid power to your DELTA Pro as a power source in the event of an outage.


This is an additional cost to set up since you’ll need the Smart Home Panel ($399 at the time of this review) plus professional installation by a licensed electrician. But in return for the investment, you’ll be able to power things that don’t easily plug in to a battery generator such as interior lighting, alarm systems and an array of circuits of your choice throughout your home—without needing to move the unit around.

User Experience and Ease of Use

One thing we appreciate about the EcoFlow DELTA Pro is its user-friendly design. The power station has a sturdy handle for easy transport and weighs just under 100 pounds, making it one of the most portable options on the market. By comparison, traditional lead-acid batteries often weigh 150 pounds or more.

The control panel is straightforward to use, with clearly labeled buttons and ports. You can charge multiple devices simultaneously without any issues or delays, making it a convenient option for outdoor activities or emergency situations.

It is also compatible with various devices, including smartphones, laptops and even mini-fridges.

EcoFlow DELTA Pro Price and Availability

At the time of this review, the power station retails for $3,599, which may seem steep compared to cheaper options on the market like lead-acid batteries. However, lead-acid batteries have a much shorter lifespan and considering its high capacity and fast charging speed, it’s a reasonable price for the value over the product’s lifetime. .

The company frequently runs promotions on the power station, which can bring the price down significantly. For example, at the time of this writing, the EcoFlow DELTA Pro is available on the company’s website for nearly $1000 off the suggested retail price. It also comes with a five-year warranty, providing peace of mind around the investment.

How the EcoFlow DELTA Pro Measures Up Against Other Portable Generators on the Market

Here’s a look at how the EcoFlow DELTA Pro stacks up against other top competitors on the market:

Anker Power House 767 vs. EcoFlow DELTA Pro

If you’re interested in portable generators, you have most likely come across the Anker 767 and EcoFlow DELTA Pro, two of the top options available on the market. While both of these generators are built on fast-charging lithium batteries, they differ in several key areas. 

The Anker 767 boasts a lower price point but has a smaller 2048Wh capacity and 2400W power output and thus could be a good option if you don’t need the power of the Delta Pro. On the other hand, the EcoFlow DELTA Pro offers a more powerful output and larger capacity but comes at a higher cost. Ultimately, choosing between these two options depends on your individual needs and preferences. 

EcoFlow DELTA Max vs. EcoFlow DELTA Pro

EcoFlow’s DELTA Max is a smaller, lower-capacity option similar to the Anker Power House 767 that has a retail price less than half of the DELTA Pro, making it a viable power station option for those on a budget or those who don’t need the higher capacity and power output of the DELTA Pro.

The DELTA Max still has a 2400W max continuous output, which means it can power most tools, appliances and devices. The 2016Wh capacity however, is much lower than the DELTA Pro, so it won’t last as long, especially when drawing lots of power for larger devices and appliances such as refrigerators.

EcoFlow DELTA Pro vs. Bluetti ac300

The Bluetti ac300 is probably the closest competitor to the DELTA Pro. Both generators offer high capacity, efficient power and a range of features to make your life easier. The price for each is nearly the same, though the capacity of the EcoFlow DELTA Pro is slightly larger.  Also, the DELTA Pro provides up to 3600W of power, whereas the Bluetti ac300 provides 3000W of power with a lighter build. 

The Bluetti ac300 weighs about half of what the DELTA Pro does, but rather than integrated wheels, the Bluetti model offers a separate cart for transport. It’s also a two-part system consisting of the AC300 control unit and add-on B300 battery block. This allows for expansion via additional B300 units, but makes it less self-contained than the DELTA Pro unit.

Bottom Line: Why We Love It

Overall, the EcoFlow DELTA Pro is a high-power, high-capacity choice for anyone in need of a reliable and efficient portable power station. Its performance, user-friendly design, and portability make it a top competitor in the market. While it has a higher price point compared to other options, its features and capabilities make it well worth the investment for those who need serious power at home or on the road. Whether you’re planning a camping trip or preparing for a power outage, the EcoFlow DELTA Pro is a versatile and powerful solution that will provide you with peace of mind and convenience.


How can I charge the EcoFlow DELTA Pro?

The EcoFlow DELTA Pro can be charged using several methods:

  • DC Input: The Delta Pro supports 11-150V DC input, with a max current of 15A.
  • Solar Charging: EcoFlow sells 400W solar panels you can pair with the DELTA Pro. The number of panels that can be used simultaneously depends on the type of panels.
  • AC Charging: You can also plug the battery directly into an AC output to charge it in about two hours and 40 minutes.
  • MultiCharge: If you have the Delta Pro’s Smart Extra Battery, it benefits from all the charging methods Delta Pro has, including a 6500W MultiCharge.

Where can I buy the Ecoflow Delta Pro?

The EcoFlow Delta Pro can be purchased from a variety of online retailers, including Amazon and Home Depot, but to ensure you get the best deal plus access to the brand’s generous warranty and excellent customer service, your best bet is to purchase directly from EcoFlow’s official website:

How long does EcoFlow DELTA Pro last?

The EcoFlow DELTA Pro comes with a five-year warranty, but it has an expected lifespan of 6,500 cycles to 50 percent capacity and 3,500 cycles to 80 percent capacity. This means that you could drain the battery to half every day for almost 10 years.

How many amp hours is EcoFlow DELTA Pro?

The EcoFlow DELTA Pro is equipped with a large lithium (LFP) battery boasting a capacity of 3600Wh. This signifies the amount of energy the battery can store, translating to a substantial amount of power for your devices though if you’re using more power-hungry devices, the battery will drain much faster.

How much is EcoFlow DELTA Pro?

The retail price at the time of this review is $3,599, but what you pay for the EcoFlow DELTA Pro may vary depending on the retailer and any additional features or accessories you choose to include. There are lots of bundle options that add additional units, home grid connections, extra batteries and more. It’s smart to check the official EcoFlow website and authorized dealers such as Amazon for the most current pricing before buying.
