EcoFlow Delta Pro vs Max Comparison & Review

The EcoFlow Delta series has proved to be one of the most successful series on the market, and for good reason. Since their launches in 2021, the EcoFlow Delta Pro and the Delta Max have made impressive sales worldwide.

However, you may have questions about which system is right for you. Let’s settle the score on EcoFlow Delta Pro vs Max.

EcoFlow Delta Max

The EcoFlow Delta Max was released at the end of 2021 and marketed as a two-day home-backup system. It was launched as a more affordable option than the Delta Pro, but how does it hold up?

Delta Max Features

The fast-charging capabilities on the Delta Max are hard to beat, as the battery can charge from 0% to 80% in around 65 minutes only with AC charging. It’s also far more portable than a gas generator, weighing only 48 pounds for the initial system with a relatively small volume.

For output, the Delta Max offers:

• 2 USB-A Ports
• 2 USB-A Fast-Charging Ports
• 2 USB-C Ports
• 6 AC outlets
• 2 DC5521 Output
• 1 Car output

Essentially, you can power nearly anything with the Delta Max, as long as it fits within the wattage capacity of 3600 running watts or 7200W surge.

Battery Performance

One of the most significant differences between the Delta Pro and the Delta Max is their battery chemistry. Both use lithium-ion batteries, but the Delta Max uses an NMC (nickel-manganese-cobalt) battery, whereas the Delta Pro uses an LFP (Lithium-iron-phosphate) chemistry.

With one full charge, you can store 2016Wh, allowing you to charge a laptop over 37 times or a refrigerator for between 16 to 32 hours, even without solar charging.

Most importantly, how long does the battery last?

The Delta and the Delta Max’s battery lasts for 800 lifecycles before dropping below 80% of its original capacity. By the standards of the industry, that’s a major achievement, but how does it hold up to the Delta Pro?

EcoFlow Delta Pro

The EcoFlow Delta Pro is, without a doubt, EcoFlow’s most powerful model to date, and arguably the best on the market. Let’s talk about what sets it apart.

Delta Pro Features

The Delta Pro has amazing output abilities, comparable to a gas generator. With the basic system, you can even power a dryer, likely the largest energy user in your home, for over a half-hour without additional batteries or solar panels.

Also, you’ll have more options to charge the Delta Pro, with state-of-the-art solar panels, AC charging, and even electric vehicle charging. You can even use a combination for the fastest possible charge.

While sold separately, you can choose to buy the Smart Home Panel, which can switch your home system to the Delta Pro battery in under 20 milliseconds if the power goes out. With an additional Smart Battery, you can charge your large appliances for days with this system, especially with the 200W panels, which can still absorb up to 100W during a storm.

Battery Performance

The EcoFlow Delta Pro is the new gold standard of the industry when it comes to battery performance, but don’t take our word for it. On one charge without any additional power, you can charge a new iPhone 313 times from empty to full.

Not only that, but the 3600Wh battery lasts for over 6,500 lifecycles before dropping below 80% of its original capacity, compared to 800 lifecycles for the Delta Max.

If you run this system from full to empty every day for ten years, you would only see a drop of 20% capacity. There is no comparison in the industry, and the average gas-powered generator only lasts for 1,500 to 3,000 hours.

EcoFlow Delta Pro vs Max: Which Is Better?

Honestly, they are both excellent models for different goals, but for maximum power, the EcoFlow Delta Pro is the superior system. Both batteries have impressive shelf lives, allowing you to store a full charge safely for over a year, and they can power small appliances for long periods.

However, the Delta Pro lasts so much longer and has a significantly higher capacity. You will have to pay a little more upfront, but the performance difference and longevity mean the system will pay for itself. Again, it depends on your needs.

If you only intend to use the system for camping, and you only plan to charge smaller appliances, the Delta Max is a perfect system. If you need a system for home backup, construction projects, or off-grid life, then the Delta Pro is the only choice.
