Differences EcoFlow Delta 3 Plus vs EcoFlow River 2 Pro
Below is a summary of the specifications:
Battery Capacity and Expandability
The battery capacity is one of the most critical aspects when choosing a power station, as it directly impacts how long it can run your devices before needing a recharge.
The EcoFlow Delta 3 Plus has a massive 3,000Wh battery, making it one of the most powerful portable power stations available. It is expandable, meaning users can increase capacity beyond 3,000Wh using additional battery modules, making it a reliable backup power solution for homes, RVs, and off-grid cabins.
In contrast, the EcoFlow Delta 2 offers a 1,024Wh battery, which is expandable with extra battery modules. While this is sufficient for short-term power needs and small appliances, it falls short when compared to the Delta 3 Plus, especially for users requiring longer runtimes or more demanding power needs.
Winner: EcoFlow Delta 3 Plus
With three times the battery capacity and expandability, the Delta 3 Plus is the superior option for extended power needs.
Power Output and Device Compatibility
Power output determines which appliances and devices a power station can run efficiently.
The EcoFlow Delta 3 Plus delivers 3,000W of continuous output with a 6,000W surge capacity, allowing it to power refrigerators, power tools, heaters, microwaves, and other large appliances. With five AC outlets, it can handle multiple high-power devices simultaneously without issue.
The EcoFlow Delta 2, in comparison, offers 1,800W of continuous power and 2,700W surge capacity, making it ideal for smaller appliances such as laptops, CPAP machines, TVs, and coffee makers. However, it struggles with high-power tools or multiple energy-demanding devices running simultaneously.
Winner: EcoFlow Delta 3 Plus
With higher power output and better surge capacity, the Delta 3 Plus is the best choice for users with high-energy needs.
Charging Speed and Solar Input
Fast charging is an essential feature for portable power stations, as it determines how quickly you can get back to full power.
The EcoFlow Delta 3 Plus supports up to 1,000W of solar input, making it one of the fastest solar-charging power stations on the market. It also features ultra-fast AC charging, reaching 80% in just 1.5 hours and 100% in 2 hours.
The EcoFlow Delta 2, while still offering fast AC charging (80% in 1.3 hours, 100% in 1.6 hours), only supports 500W of solar input. This means solar charging takes longer compared to the Delta 3 Plus, which may not be ideal for users relying on off-grid solar power.
Winner: EcoFlow Delta 3 Plus
With faster solar input and quicker recharging speeds, the Delta 3 Plus is the better choice for renewable energy users.
Portability and Weight
Portability is crucial for outdoor users, but it often comes at the cost of battery capacity and power output.
The EcoFlow Delta 3 Plus, due to its massive battery and high power output, weighs 65 lbs (29.5 kg). While it is still portable, it is significantly heavier than the Delta 2, making it less ideal for frequent transport.
The EcoFlow Delta 2, at 27 lbs (12 kg), is much lighter and more compact, making it easier to carry and transport for camping, RV trips, and outdoor events.
Winner: EcoFlow Delta 2
For maximum portability, the Delta 2 is the clear winner.
Durability and Battery Lifespan
Both models use LiFePO₄ (LFP) battery technology, known for long lifespan, safety, and efficiency. Each power station offers 3,000+ charge cycles, ensuring years of reliable performance.
Winner: Tie
Both Delta 3 Plus and Delta 2 have long-lasting battery technology and durability.
