Both models provide exceptional performance, but they have distinct characteristics that make each more suitable for different use cases.

Key Features Comparison

The DELTA 2 and RIVER 2 Pro share several advanced features, including fast charging capabilities and long battery lifespans, but they are designed for different purposes, reflected in their output capacities and battery technologies.

Feature	EF ECOFLOW DELTA 2	EF ECOFLOW RIVER 2 Pro
Battery Capacity	1024Wh (LiFePO4)	768Wh (LiFePO4)
AC Output	1800W (surge 3300W)	800W (surge 1600W)
Solar Charging	500W input (Fast charge in 3 hours)	220W input (Fast charge in 3.5 hours)
Charging Time (AC)	0-80% in 50 mins	0-80% in 70 mins
Weight	27 lbs	17.2 lbs
Expansion Capability	Yes, expandable to 3kWh	No expansion options

The DELTA 2 stands out with a higher battery capacity of 1024Wh, which is ideal for users needing more energy to power larger or more devices. It also boasts an impressive 1800W output with a surge capacity of 3300W, which means it can handle more demanding appliances compared to the RIVER 2 Pro. Additionally, the DELTA 2 can be expanded with extra batteries to reach up to 3kWh, making it a great option for extended off-grid use or high-energy demands.

On the other hand, the RIVER 2 Pro offers a slightly smaller battery capacity of 768Wh but has a very fast recharge time of 70 minutes using AC power. It also features a 1600W surge capacity, which is suitable for most household appliances but may struggle with larger or more power-hungry devices. Unlike the DELTA 2, the RIVER 2 Pro does not support battery expansion, limiting its versatility for larger energy needs.

Portability and Ease of Use

When it comes to portability, the RIVER 2 Pro takes the lead due to its lightweight design. Weighing only 17.2 lbs, it’s easy to carry around, making it perfect for outdoor adventures like camping or RV trips. The built-in handle adds convenience, ensuring users can move it effortlessly from one location to another.

In contrast, the DELTA 2 weighs 27 lbs, which is heavier but still manageable for most users. While it is more substantial, the extra weight comes with a significant increase in capacity and power. For those looking to use a portable power station as a home backup or to run multiple larger appliances, the DELTA 2 might be more suitable despite its heavier build.

Both models are user-friendly, with clear displays, easy-to-understand interfaces, and a variety of output options. The DELTA 2 has more outlets overall, including USB-C, DC, and multiple AC ports, making it ideal for simultaneous device charging.

Solar Charging and Energy Efficiency

Both the DELTA 2 and RIVER 2 Pro offer solar charging, allowing users to recharge them using renewable energy. However, the DELTA 2 outperforms the RIVER 2 Pro in solar input. The DELTA 2 supports a 500W solar input, allowing it to recharge fully in about 3 hours, whereas the RIVER 2 Pro supports up to 220W of solar input, requiring around 3.5 hours for a full recharge.

The ability to recharge via solar panels is essential for those planning extended off-grid trips or wanting to maintain a sustainable energy source. If fast solar recharging is a priority, the DELTA 2 is the better option due to its higher solar input capacity.

Battery Longevity and Durability

One of the standout features of both the DELTA 2 and RIVER 2 Pro is their use of LiFePO4 (Lithium Iron Phosphate) battery technology, which offers longer life cycles and better safety compared to traditional lithium-ion batteries. Both models are rated for 3000+ charge cycles, which translates to roughly 10 years of regular use before the battery drops to 80% of its original capacity.

While both models promise durability, the DELTA 2’s larger capacity and expansion options may offer more flexibility and longevity for users who rely on their power station for extended periods. The RIVER 2 Pro, with its smaller battery and compact design, is more suited for shorter-term or less intensive use but still provides excellent longevity for casual users.
