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

Overview of the Anker SOLIX C300 DC Power Bank Station and EF ECOFLOW Portable Power Station RIVER 2 Pro

The Anker SOLIX C300 is priced at $179.99, while the EF ECOFLOW RIVER 2 Pro is significantly higher at $339.00. This price difference of about 88% reflects the varying capacities and features of these two portable power stations. While both products serve the purpose of providing reliable power for outdoor activities and emergencies, they cater to different user needs and preferences.

Power Capacity and Output

The Anker SOLIX C300 offers a capacity of 288Wh and a maximum output of 300W, making it suitable for charging smaller devices. In contrast, the EF ECOFLOW RIVER 2 Pro boasts a much larger capacity of 768Wh and can deliver up to 1600W, enabling it to power a wider range of appliances, including high-wattage devices. Thus, if you require a power station for extensive camping or home backup, the RIVER 2 Pro is the more capable choice.

Charging Speed

When it comes to charging speed, the EF ECOFLOW RIVER 2 Pro excels with its industry-leading X-Stream fast charging technology, allowing it to fully recharge in just 70 minutes using an AC outlet. In comparison, the Anker SOLIX C300 can reach 80% charge in about an hour with its dual PD 3.1 USB-C ports. While both power stations offer efficient charging, the RIVER 2 Pro's rapid charging capability is especially beneficial for users in need of quick turnaround times.

Portability and Design

The Anker SOLIX C300 is designed to be compact and lightweight, making it 30% smaller than similar power stations, which enhances its portability. It weighs significantly less than the EF ECOFLOW RIVER 2 Pro, which weighs 17.2 lbs but is still considered lightweight for its class. If portability is a primary concern—especially for hiking or camping—the Anker SOLIX C300 may appeal more to users who prioritize a smaller, easier-to-carry option.

Battery Technology and Durability

Both products utilize LiFePO4 (lithium iron phosphate) battery technology, which is known for its longevity and safety. The Anker SOLIX C300 comes with a 3-year guarantee, while the EF ECOFLOW RIVER 2 Pro can be recharged over 3000 times before reaching 80% capacity, providing nearly 10 years of regular use. This long-lasting performance is a significant advantage for users planning to use their power stations frequently over the years.

Versatility of Charging Ports

The versatility in charging ports is another area where the EF ECOFLOW RIVER 2 Pro shines. It features 11 outlets, including multiple 800W AC outlets and USB-C ports, allowing simultaneous charging of numerous devices without risk of overload. In contrast, the Anker SOLIX C300 has seven device charging ports, including two 140W USB-C ports and a car socket. For users who need to charge multiple devices at once, the RIVER 2 Pro’s greater number of outlets is a clear benefit.

Solar Charging Capability

Both power stations offer the option for solar charging, but the methods differ. The Anker SOLIX C300 is compatible with 100W or 60W Anker solar panels for sustainable power on the go. On the other hand, the EF ECOFLOW RIVER 2 Pro can recharge using solar panels in as fast as 3.5 hours with a 220W input. This superior solar charging capability makes the RIVER 2 Pro a better option for users who plan to rely on solar power during extended outdoor excursions.

Price Comparison

With a price of $179.99, the Anker SOLIX C300 is about 47% cheaper than the EF ECOFLOW RIVER 2 Pro, which retails for $339.00. This significant price difference may appeal to users looking for budget-friendly options or those who only need basic functionalities. However, the RIVER 2 Pro's higher price correlates with its advanced features and larger capacity, making it a better investment for power users.

Which should you buy?

Ultimately, the choice between the Anker SOLIX C300 and the EF ECOFLOW RIVER 2 Pro depends on your specific needs. If you prioritize a lightweight, affordable power station primarily for smaller devices and occasional use, the Anker SOLIX C300 is a great option at $179.99. However, if you require a more powerful, versatile station capable of handling high-wattage devices and multiple simultaneous charges, the EF ECOFLOW RIVER 2 Pro, despite its higher price of $339.00, is the superior choice for serious outdoor enthusiasts and emergency preparedness.
