Anker SOLIX C1000 Gen 2 Portable Power Station, vs EF ECOFLOW Portable Power Station RIVER 2 Pro,

Updated July 2026 — full head-to-head comparison.

Pricing and Value

The Anker SOLIX C1000 Gen 2 Portable Power Station is priced at $499.99, while the EF ECOFLOW Portable Power Station RIVER 2 Pro costs $339.00, making it about 17% cheaper than the Anker model. This price difference may be significant for those on a budget. Despite the lower price, the RIVER 2 Pro still offers a solid capacity of 768Wh, which is suitable for many outdoor and home use scenarios. In contrast, the Anker provides a larger capacity of 1,024Wh, which can power more devices simultaneously. Both products are well-regarded, with the Anker ranked 2,357 in sales and the ECOFLOW ranked 6,537, indicating a stronger sales performance for the Anker.

Power Output and Capacity

The Anker is designed to deliver a peak output of 3,000W and continuous output of 2,000W, capable of powering up to 10 devices at once. In comparison, the EF ECOFLOW can output up to 1,600W, which is sufficient for about 80% of household appliances. While the RIVER 2 Pro supports charging multiple devices simultaneously with its 11 outlets, those requiring more power may find the Anker's higher output more advantageous, especially in situations demanding power for larger devices or multiple appliances.

Charging Speed

When it comes to recharging speed, the Anker SOLIX C1000 boasts an ultra-fast charging feature that allows it to fully recharge in just 49 minutes using its HyperFlash technology. On the other hand, the RIVER 2 Pro also emphasizes rapid charging, achieving a full recharge in 70 minutes via AC outlets. The Anker's faster recharging capability may be crucial for users needing quick turnaround times during power outages or outdoor activities. However, the RIVER 2 Pro offers a compelling solar charging option, taking approximately 3.5 hours to recharge with a 220W solar input.

Portability and Design

Portability is a significant factor in choosing a portable power station, and the EF ECOFLOW RIVER 2 Pro is lighter, weighing in at only 17.2 lbs. In comparison, the Anker SOLIX C1000 is slightly heavier, though specific weight details are not provided. The Anker emphasizes its compact design, being 14% smaller and 11% lighter than similar models, which aids in ease of transport. Therefore, while the RIVER 2 Pro is inherently more lightweight, both models offer designs that cater to users who need to move them frequently.

Battery Technology and Lifespan

Both power stations utilize advanced Lithium Iron Phosphate (LiFePO4) batteries, which are known for their longevity and safety. The Anker’s battery is rated for 4,000 cycles, maintaining at least 80% capacity after this period, which translates to about 10 years of regular use. The RIVER 2 Pro also boasts a similar lifespan, allowing for over 3,000 cycles before reaching 80% capacity. Users can expect a long-lasting performance from both units, but the Anker may provide a slight edge in cycle longevity, making it a better investment for those planning to use it extensively over the years.

Features and Usability

The Anker SOLIX C1000 Gen 2 includes features like a 10 ms UPS backup, which is ideal for keeping critical devices running during power interruptions. It also offers an app for managing power usage, a feature that adds convenience for remote work setups. Conversely, the RIVER 2 Pro focuses on providing versatile outlet options with 11 total outputs and advanced battery management system (BMS) for safety. Each product serves different user needs: the Anker for those requiring robust backup capabilities, and the ECOFLOW for users looking for versatility in powering various devices.

Solar Charging Capability

Solar charging is a strong point for both models, although their performance varies. The Anker SOLIX C1000 can recharge fully using solar power in just 1.8 hours with a 600W input, making it an excellent choice for off-grid living. In contrast, the RIVER 2 Pro takes about 3.5 hours to recharge with a 220W input. For users focused on sustainability and off-grid use, the Anker's quicker solar charging time may be a considerable advantage, allowing for more efficient use of renewable energy sources during outdoor adventures.

Which should you buy?

Ultimately, the choice between the Anker SOLIX C1000 Gen 2 Portable Power Station and the EF ECOFLOW RIVER 2 Pro depends on your specific needs. If you require a larger capacity, faster charging, and superior backup features, the Anker may be worth the extra cost. However, if you are looking for a more budget-friendly option that still offers ample power and portability, the RIVER 2 Pro presents a compelling choice. Both models are excellent in their rights and cater to different user preferences, making them worthy contenders in the portable power station market.
