Differences Anker Solix C1000 vs EcoFlow Delta 2
Below is a summary of the specifications:
Battery Capacity and Expandability
Battery capacity is a key factor when choosing a power station, as it determines how long the unit can power devices before requiring a recharge.
The Anker Solix C1000 has a slightly larger battery capacity at 1,056Wh, compared to the EcoFlow Delta 2’s 1,024Wh battery. This small difference does not significantly impact performance but gives the Anker Solix C1000 a minor edge in runtime.
However, the EcoFlow Delta 2 has the advantage of expandability, allowing users to increase the total battery capacity up to 3,000Wh with additional battery packs. The Anker Solix C1000 is not expandable, making it less versatile for users who need extended runtime.
Winner: EcoFlow Delta 2
Despite the Anker Solix C1000 having a slightly larger battery, the Delta 2 wins due to its expandable capacity.

Power Output and Device Compatibility
Power output determines which appliances and devices a power station can run efficiently.
Both the Anker Solix C1000 and EcoFlow Delta 2 provide 1,800W of continuous power, making them capable of handling most household appliances, camping gear, and small power tools. However, the Delta 2 has a higher surge capacity (2,700W vs. 2,400W), allowing it to handle larger startup surges from high-powered devices like refrigerators or air conditioners.
Both units feature 6 AC outlets, making them convenient for multi-device setups, but the Delta 2 has more USB-A ports, which can be useful for charging smaller gadgets.
Winner: EcoFlow Delta 2
With a higher surge capacity and more USB-A ports, the Delta 2 is better suited for running demanding appliances and multiple devices.
Charging Speed and Solar Input
Fast charging is essential for minimizing downtime, especially in off-grid or emergency situations.
The Anker Solix C1000 charges faster, reaching 80% in just 58 minutes and 100% in 1.5 hours, thanks to HyperFlash charging technology. The EcoFlow Delta 2 takes about 80 minutes to reach 80% and 1.6 hours for a full charge, making it slower than Anker’s model.
When it comes to solar input, the Anker Solix C1000 supports up to 600W of solar charging, while the EcoFlow Delta 2 is limited to 500W. This means that the Solix C1000 will recharge slightly faster when using solar panels.
Winner: Anker Solix C1000
With faster AC charging and higher solar input, the Solix C1000 is the superior choice for users who prioritize rapid recharge times.

Portability and Weight
Portability is crucial for outdoor adventurers and those who frequently transport their power stations.
The Anker Solix C1000 weighs 28.4 lbs (12.9 kg), while the EcoFlow Delta 2 is slightly lighter at 27 lbs (12.2 kg). This difference is negligible, meaning both units are equally portable and easy to carry.
Winner: Tie
Both power stations are lightweight and compact, making them equally portable.
Durability and Battery Lifespan
Both Anker Solix C1000 and EcoFlow Delta 2 use LiFePO₄ (LFP) battery technology, which is more durable and longer-lasting than traditional lithium-ion batteries. Each power station offers 3,000+ charge cycles, ensuring years of reliable performance.
Winner: Tie
Both power stations have a long-lasting battery lifespan and excellent durability.
