Differences Anker Solix C1000 vs EcoFlow Delta 2 Max
Below is a summary of the specifications:
Battery Capacity and Expandability
Battery capacity determines how long a power station can run your devices before requiring a recharge.
The Anker Solix C1000 features a 1,056Wh LiFePO₄ battery, making it suitable for short trips, camping, and powering small to medium appliances. However, it does not support battery expansion, meaning users are limited to its default capacity.
In contrast, the EcoFlow Delta 2 Max comes with a larger 2,048Wh battery, double the capacity of the Solix C1000. More importantly, it is expandable up to 6,144Wh, allowing users to extend its power for longer home backup or off-grid use.
Winner: EcoFlow Delta 2 Max
With a significantly larger base capacity and expandability, the Delta 2 Max is the superior choice for users needing extended runtime.

Power Output and Device Compatibility
The ability to power multiple high-wattage devices simultaneously is crucial for choosing a reliable power station.
The Anker Solix C1000 provides 1,800W of continuous output and 2,400W surge power, making it suitable for running appliances like laptops, refrigerators, TVs, and small kitchen devices. It features six AC outlets, ensuring flexibility for multiple devices.
The EcoFlow Delta 2 Max, on the other hand, offers 2,400W of continuous power and an impressive 4,800W surge capacity, making it capable of handling power-hungry devices like power tools, heaters, and large refrigerators. Like the Solix C1000, it also has six AC outlets, but it delivers more power per outlet.
Winner: EcoFlow Delta 2 Max
With higher power output and a better surge capacity, the Delta 2 Max is the better choice for demanding applications.
Charging Speed and Solar Input
Fast charging is essential, especially for off-grid and emergency backup users.
The Anker Solix C1000 supports up to 600W of solar input and can fully recharge in approximately 1.8 hours using AC power.
The EcoFlow Delta 2 Max supports a higher solar input of 1,000W, allowing it to charge significantly faster when using solar panels. It also features EcoFlow’s X-Stream technology, which enables ultra-fast AC charging—reaching 80% in just 1.3 hours and 100% in 1.6 hours.
Winner: EcoFlow Delta 2 Max
With a higher solar input and significantly faster charging times, the Delta 2 Max is the clear winner for off-grid charging.

Portability and Weight
Weight and portability play a crucial role for campers, RV users, and those who frequently move their power station.
The Anker Solix C1000 weighs only 29.8 lbs (13.5 kg), making it lightweight and easy to transport for outdoor trips and small-scale energy needs.
The EcoFlow Delta 2 Max, at 50 lbs (22.7 kg), is heavier but comes with twice the battery capacity and a higher power output. While not as portable as the Solix C1000, it is still manageable for home and RV users.
Winner: Anker Solix C1000
For maximum portability, the Anker Solix C1000 is the better choice.
