Differences EcoFlow Delta 3 Plus vs EcoFlow Delta Pro
Below is a summary of the specifications:
Battery Capacity and Expandability
The battery capacity is crucial when selecting a portable power station. The EcoFlow Delta 3 Plus is equipped with a 1,024Wh battery, making it suitable for powering medium-duty devices like laptops, small refrigerators, and small appliances. With LiFePO₄ battery technology, the Delta 3 Plus offers 4,000 charge cycles before its battery drops to 80% of its original capacity. This makes it a great option for those who need dependable power for multiple devices over extended periods.
In comparison, the EcoFlow Delta Pro comes with a 3,600Wh battery, which is ideal for users with higher power demands. This larger battery can handle heavier-duty appliances such as air conditioners, refrigerators, power tools, and larger kitchen appliances. Like the Delta 3 Plus, the Delta Pro uses LiFePO₄ technology and offers an even longer lifespan with 6,500 charge cycles. Additionally, the Delta Pro supports expandability, allowing users to add extra EcoFlow Smart Batteries, scaling its total capacity to a massive 25,000Wh.
Winner: EcoFlow Delta Pro
While the EcoFlow Delta 3 Plus offers a great balance of capacity and reliability for medium-duty use, the EcoFlow Delta Pro provides more battery capacity and the ability to expand its energy capacity for heavy-duty appliances.

Power Output and Device Compatibility
The power output determines which devices a portable power station can support and how many devices it can power simultaneously. The EcoFlow Delta 3 Plus provides 1,800W continuous output with 3,600W surge capacity, making it ideal for powering medium-duty devices like laptops, mini-fridges, small appliances, and small power tools. This surge capacity ensures that it can handle devices that require a high initial burst of power, such as microwaves or coffee makers.
The EcoFlow Delta Pro, with its 3,600W continuous output and 7,200W surge capacity, can power heavier-duty devices like air conditioners, refrigerators, large power tools, and even entire homes in case of a power outage. Its surge capacity allows it to handle the startup power of large devices with ease, making it the ideal choice for off-grid living or RV use.
Winner: EcoFlow Delta Pro
The EcoFlow Delta Pro offers significantly higher power output, making it the better choice for powering larger devices and heavy-duty appliances.
Charging Speed and Solar Input
Charging speed is critical for users who need to recharge their power stations quickly, especially in off-grid or emergency situations.
The EcoFlow Delta 3 Plus charges from 0% to 100% in just 1.8 hours using AC power, which is incredibly fast. It also supports 800W solar input, allowing it to fully recharge in 5-6 hours under optimal solar conditions, making it an excellent option for users relying on solar power during off-grid activities.
The EcoFlow Delta Pro takes slightly longer to recharge, with a 2.7-hour AC charging time from 0% to 100%. However, it supports a much higher 1,600W solar input, meaning it can fully recharge in 4-5 hours under ideal solar conditions. This higher solar input capacity makes the Delta Pro an even better choice for off-grid living or solar-powered solutions.
Winner: EcoFlow Delta Pro
The EcoFlow Delta Pro offers faster solar recharging due to its higher solar input capacity, making it the better option for those looking to recharge quickly in off-grid environments.

Portability and Weight
When it comes to portability, the EcoFlow Delta 3 Plus is much lighter, weighing only 14.5 kg, which makes it more manageable for travel or outdoor activities. Its compact design makes it easier to carry around and transport, especially for users who need a power solution for light-duty devices.
The EcoFlow Delta Pro, however, is heavier at 45 kg and is significantly larger in size. While it is portable with wheels, it is better suited for home backup and RV use, where weight and size are less of a concern.
Winner: EcoFlow Delta 3 Plus
For users who prioritize portability, the EcoFlow Delta 3 Plus is the better choice due to its lightweight and compact design.
Durability and Battery Lifespan
Both the EcoFlow Delta 3 Plus and the EcoFlow Delta Pro use LiFePO₄ batteries, known for their longevity, thermal stability, and resilience. The Delta 3 Plus provides 4,000 charge cycles, ensuring a long lifespan and reliable performance for years of use.
The Delta Pro, with its 6,500 charge cycles, offers an even longer battery lifespan, making it ideal for users who require frequent use and want to ensure their power station lasts for many years.
Winner: EcoFlow Delta Pro
The EcoFlow Delta Pro has a significantly longer battery lifespan, making it a better investment for long-term use.
