EcoFlow DELTA Pro Review: Is It Still a Good Buy in 2024?

When the EcoFlow DELTA Pro launched in 2021, it shattered Kickstarter’s record and became the most funded tech project ever to be featured on the platform. Fast forward to 2024 and the question on everyone's mind is: is the EcoFlow DELTA Pro still worth buying? 

With solar technology evolving incredibly fast and new power station models and brands regularly entering the market, we wanted to take a deep dive into one of the industry’s true game changers to determine whether or not this iconic solar generator still holds up today.

From reviewing the DELTA Pro’s specs and features to seeing how it compares to newer models, we’ll cover everything you need to know. Let’s get started! 

What is the EcoFlow DELTA PRO? 

Unless you’re completely new to solar and portable power stations, you’re probably pretty familiar with the DELTA Pro. When it was first introduced, EcoFlow set a new standard for portable power stations.

Its impressive specs and versatility quickly made it a favorite among users needing reliable backup power for their homes or portable power for RVs. Put simply, it was bigger, better, and more powerful than anything that came before it.

However, with the release of newer models, like the EcoFlow DELTA Pro’s successors, the DELTA ULTRA and the EcoFlow DELTA Pro 3, many are wondering if the original DELTA Pro can still compete. 

The DELTA PRO’s Design and Portability 

One of the first things you'll notice about the DELTA Pro is its size and weight. This unit is hefty, weighing almost 100 pounds. While it does come with a convenient and extendable suitcase-style handle and a set of wheels, maneuvering it can still be a challenge, especially if you're planning to use it for RV or portable applications.

Still, its bulky dimensions and heavy build weren’t really considered to be overly off-putting when it was released, as the DELTA PRO was designed to store and deliver more power than anything else available at the time.

Charging Options 

The DELTA Pro offers several charging options, which adds to its versatility: 

AC Wall Outlet Charging: The DELTA PRO can be plugged directly into a standard outlet for a straightforward charge. This allows you to have a reliable source of power for when the power goes out, or if you’re taking your DELTA PRO to an off-grid location. 

Solar Charging: The DELTA PRO was designed to work with solar panels for off-grid and backup charging. With a 1,600W solar input, it’s possible to fully charge the internal battery in under three hours, making it a practical off-grid power station. 

DC Car Charging: A 12-volt car plug allows for charging on the go. Definitely not the unit’s most exciting feature, but it is something that is notably lacking from the DELTA Pro 3. It could be useful for RV and camper van enthusiasts.

EV Charging: One of the standout features when the DELTA Pro was released was its ability to be fully charged via EV charging stations through its dedicated EV charger port. With more EV charging stations popping up each year, it’s still a really useful feature, especially for those living in RVs or traveling extensively. 

Expandability 

The DELTA Pro was designed with expandability in mind. It has two expansion battery ports, allowing you to connect additional batteries for increased capacity. With the right configuration, you store up to 25kWh of power, making it suitable for extensive home backup solutions.

While you can purchase kits, the batteries are usually sold separately. Expansion batteries might seem like a fairly standard option these days; however, in 2021, this was a pretty revolutionary concept. Basically, it allows you to transform your power station into the heart of a backup power ecosystem, especially when you pair it with the EcoFlow Smart Home Panel.

Performance and Features 

Battery and Inverter: 

The DELTA Pro boasts a 3,600Wh internal battery and a 3,600W inverter. This means it can still handle a wide range of high-power appliances and devices with ease. With that said, unless you pair it with the expansion batteries, you can drain the battery in roughly an hour if you’re running it at full capacity. 

Connectivity:

It includes four standard AC outlets and a 30-amp outlet, making it practical for various applications, including RVs and home backup. It also has two USB-A ports, two USB-Ports, and a DC output, which is great for situations where you just want to give your portable devices some juice. 

User Interface: 

The DELTA Pro’s user interface remains one of the best out there, which is something EcoFlow has a bit of a reputation for. With a clear and straightforward screen that displays runtime estimates, remaining battery percentages, and input/output data, you can access most of the information you would want to know directly from the unit itself. 

The accompanying app, inspired by Apple and Tesla's design, isn’t dated at all and still provides easy remote monitoring and control. 

Durability: 

The DELTA Pro was designed with a lithium iron phosphate (LiFePO4) battery, offering 3,500 life cycles before the battery degrades to 80% of its original capacity. This means you can charge and discharge the unit daily for nearly a decade before noticing significant battery wear. A big plus for those wondering if the DELTA Pro is still a reliable option. 

So, is it Still Worth the Price?

Despite the arrival of newer models, we still firmly believe the EcoFlow DELTA Pro remains a strong contender in 2024. Here’s why: 

Affordability: 

Sure, the newer models offer some flashy new features, but with each new release, the price of the DELTA Pro has decreased significantly. This makes it a cost-effective option for those seeking simple and reliable backup power. Currently priced around $2,500, it offers substantial savings compared to its successors and competitors.

In our recent review of the EcoFlow DELTA Pro 3, we actually compared it to the latest version of the DELTA PRO to a new iPhone release. Sure, if you desperately need a power station and you have the budget for it, why not get the latest option and all of the features that come with that? On the other hand, if you just need basic backup power, or you’re on a tight budget, you can save yourself some serious cash by picking up the original DELTA Pro. Use those savings for solar panels, expansion batteries, or whatever else you want to spend your hard-earned money on. 

The Features: 

Many of the features that made the DELTA Pro revolutionary—such as its impressive output power, multiple charging options, and expandability—are still relevant and useful today. In many ways, EcoFlow nailed all of the average person’s primary power station needs with the DELTA Pro. More recent models have some interesting and convenient features, and they’re more powerful, but the original just does everything you need it to do reasonably well. 

Durability and Longevity: 

The durable lithium iron phosphate battery ensures long-term usability, providing value over time. Plus, the unit itself is a bit of a tank. There is a reason why people who bought the DELTA Pro back in 2021 are still using it – it just works. 

Comparisons with Newer Models and Competitors 

The DELTA Pro ULTRA and the DELTA Pro 3: 

These newer models offer enhanced features and performance improvements but come at a higher price point. For those who need the absolute latest in technology, these might be worth considering. However, if you're looking for a balance of performance and affordability, the original DELTA Pro is still a fantastic choice.

With that said, if you need serious backup power, the DELTA Pro ULTRA’s 6kWh battery and ability to be paired with batteries for a mild-blowing total storage capacity of 90kWh makes it a better option for whole-home power. Just remember, this extra storage capacity and output power comes with a pretty hefty price tag.   

The Bluetti AC300:

Bluetti’s closest match for the DELTA Pro offers similar capacity but is bulkier and significantly less portable, making the DELTA Pro a more versatile option. The AC300 is basically just a big heavy box, where the DELTA Pro features wheels and a telescopic handle that makes it much easier to maneuver. 

The Jackery 3000 Pro: 

This newer model is comparable but also comes in at a higher price point. Given that they go toe-to-toe on specs, features, and performance, the DELTA Pro is just a more budget-friendly choice. There really isn’t enough there from Jackery to justify the added cost. 

Our Final Thoughts: Should You Pick Up an EcoFlow DELTA Pro? 

In 2024, the EcoFlow DELTA Pro continues to be a worthwhile investment. Its combination of high output power, versatile charging options, and a long-lasting, expandable battery means it still has plenty to offer. 

Simply put, it continues to be a reliable choice for both home backup and portable power needs. As prices continue to drop, it’s just a really solid, cost-effective power station that will still perform just as well as it did when it was first released. The fact that it’s still in production and continues to be a really popular option is just a testament to how far EcoFlow knocked it out of the park when they first dropped the DELTA Pro.
