EcoFlow Delta Pro vs Delta Pro 3: Comprehensive Comparison

Jun 15, 2025

Need a Portable Power Station but torn between the EcoFlow Delta Pro and the shiny new Delta Pro 3?
Short answer: get the Delta Pro 3 if you want faster charging, more power, and future-ready features.
Still unsure? Stick around—we’re unpacking everything, minus the tech headache.

At a Glance: EcoFlow Delta Pro vs Delta Pro 3 Key Performance Metrics

Power Output and Surge Capacity (Pmax, Psurge)

The EcoFlow Delta Pro offers a steady output of 3600W. The Delta Pro 3 pushes that to 4000W.

Both models can handle most home appliances without breaking a sweat. However, the Pro 3 is better equipped for high-wattage gear, giving it a performance edge.

Ideal for heavier loads or more demanding setups.

Battery Capacity and Lifespan (Wh, Cycles)

The Delta Pro features a 3600Wh battery. The Delta Pro 3 steps it up to 4480Wh.

This upgrade results in noticeably longer runtime. For example, a standard fridge runs for around 36 hours on the Delta Pro and up to 48 hours on the Pro 3.

Both units offer long cycle lives, though the Pro 3 brings in improved efficiency, with 4,000 cycles needed to reduce to 80% capacity, rather than 3,500 as with the Delta Pro.

Charging Speeds (AC, Solar, and Combined Input)

The Delta Pro 3 charges from 0–80% in just 65 minutes with high-power input. In comparison, the Delta Pro takes around 80 minutes to reach the same level.

Both support multiple charging options: AC wall input, solar panels, and car charging.

The Pro 3's upgraded internals make it more efficient, particularly when combining solar and AC inputs.

Dimensions and Portability (Weight and Physical Size)

Despite the power boost, both models remain fairly portable.

The Delta Pro weighs about 45kg. The Delta Pro 3 comes in at around 48kg.

Each includes sturdy handles for easy movement, but the Pro 3 introduces minor design tweaks, like a new colour scheme and easier port access.

Charging Ecosystem and Expandability

Maximum Solar Input (Wsolar): A Game Changer for Off-Grid?

The Delta Pro 3 is a standout when it comes to solar input.

Its improved charge controller allows it to convert more sunlight into usable energy, more efficiently than its predecessor.

This makes it particularly appealing for off-grid users who rely heavily on solar charging.

Battery Expansion for Whole-Home Backup (kWh Ecosystem)

EcoFlow’s Delta Pro already supports expansion up to 25kWh.

The Delta Pro 3 maintains this feature and improves the experience slightly.

If you're building a backup system for your entire home, both are capable, but the Pro 3’s ecosystem is more future-proof.

Smart Home Panel and Accessory Compatibility

Both models work with EcoFlow’s Smart Home Panel and various add-ons.

However, the Delta Pro 3 integrates more seamlessly with newer accessories.

You also get improved app support, real-time energy tracking, and smarter integration options with the updated model.

The Verdict: New Features, Use Cases, and Is It Worth Upgrading?

What Are the Major Upgrades in the Delta Pro 3?

Though not heavily advertised, the Delta Pro 3 now supports dual-voltage output.

This means it can power both standard devices and high-voltage equipment without the need for extra gear.

Great news for users with mixed-voltage requirements at home or on the road.

Enhanced User Experience (Noise Levels, App Features, Design)

The Pro 3 isn’t just more powerful—it’s more user-friendly.

It runs more quietly, offers a cleaner interface, and comes with app features that are easier to use.

Design-wise, the port layout is improved, and display feedback is more intuitive.

Next-Generation Inverter and Battery Technology

With a smarter inverter and upgraded battery management, the Pro 3 delivers better performance under load.

It charges faster, runs cooler, and uses energy more efficiently.

That translates to longer life, better safety, and real-world energy gains.

Who Should Buy Which Model?

The Case for the Original EcoFlow Delta Pro

Still a strong choice.

If you’re on a budget but want reliability, the original Delta Pro is more than capable.

Ideal for casual use, weekend trips, or basic home backup needs where speed and solar aren’t top priority.

Who Should Upgrade or Buy the Delta Pro 3?

Go for the Pro 3 if you value speed, expandability, and smart features.

It’s best suited for full-time off-grid users, larger backup setups, or those who want the latest tech.

It’s a clear upgrade for anyone serious about portable power.

Price vs. Performance: A Final Value Analysis

While the Delta Pro saves money upfront, the Pro 3 delivers better long-term value.

It offers faster charging, more power, and a future-ready ecosystem.

If you're thinking beyond the basics, the Pro 3 is worth the investment.
