The Anker SOLIX C300 is priced at $179.99, while the EF ECOFLOW DELTA 2 is significantly more expensive at $379.00. This price difference of about 110% highlights the distinct functionalities and target uses of these devices.
Power Capacity
The Anker SOLIX C300 offers a power capacity of 288Wh, which is suitable for light to moderate power needs during outdoor activities like camping and traveling. In contrast, the EF ECOFLOW DELTA 2 features an impressive 1024Wh capacity, allowing it to serve as a robust backup power source, especially when paired with the DELTA 2 power station to expand to 2048Wh. This means the DELTA 2 can handle more demanding appliances and longer usage durations, making it ideal for home backup or extensive outdoor use.
Charging Options
The charging options for the Anker SOLIX C300 are versatile, allowing users to recharge through USB-C ports or solar panels, though it notably lacks a wall charger. It can fast charge to 80% in about one hour using a compatible USB-C charger. On the other hand, the EF ECOFLOW DELTA 2 allows for charging through multiple methods, including AC outlets, car outlets, and solar panels. It boasts a rapid charging capability, going from 0-80% in just 80 minutes. This greater flexibility in charging methods makes the DELTA 2 more appealing for those who need consistent power availability.
Portability
The Anker SOLIX C300 is designed with portability in mind, being about 30% smaller than comparable power stations. This compact design makes it easier to transport, especially for camping trips or travel. Additionally, it has a convenient strap option for enhanced mobility. In contrast, while the EF ECOFLOW DELTA 2 is also portable, its larger size reflects its greater power capacity. Users who prioritize lightweight and compact designs may find the Anker SOLIX C300 more suitable for their needs.
Device Compatibility
In terms of device compatibility, the Anker SOLIX C300 can power up to seven devices simultaneously through various ports, including USB-C and USB-A. However, it provides a maximum output of 300W, limiting the kind of devices that can be powered at once. In comparison, the EF ECOFLOW DELTA 2 can output 1800W and supports up to 15 outlets when paired with the DELTA 2 power station. This makes it capable of powering a wider range of home appliances, making it a strong candidate for those needing to run multiple high-wattage devices.
Durability and Lifespan
The Anker SOLIX C300 features LiFePO4 batteries and comes with a three-year guarantee, ensuring reliable performance across its lifespan. Its impact-resistant design adds an extra layer of durability for outdoor use. Meanwhile, the EF ECOFLOW DELTA 2 also employs LFP battery chemistry, with a lifespan of over 3000 cycles, which means it can last considerably longer under regular use. This longevity makes the DELTA 2 a more durable investment for users who plan to rely on their power station frequently.

At $179.99, the Anker SOLIX C300 is positioned as a budget-friendly option for those in need of portable power. In contrast, the EF ECOFLOW DELTA 2 is priced at $379.00, which is about 110% more expensive than the Anker model.
