Differences Anker SOLIX C1000 vs EcoFlow Delta 3 Plus
Below is a summary of the specifications:
Battery Capacity, Expandability, and Battery Lifespan
The Anker SOLIX C1000 comes with a built-in 1,056Wh LFP battery, slightly edging out the 1,024Wh capacity of the EcoFlow Delta 3 Plus. Both units use LiFePO₄ battery chemistry, known for exceptional thermal safety and longevity. The difference comes in the battery lifespan, where the Delta 3 Plus leads with 4,000 cycles to 80% capacity, compared to the C1000’s 3,000 cycles.
Where the Delta 3 Plus really takes the lead is expandability. It supports a massive extension up to 7,680Wh using EcoFlow’s Smart Extra Batteries, transforming it into a full home-backup solution. The Anker SOLIX C1000, on the other hand, only expands up to 2,112Wh with an additional battery module, which is more limited but still practical for short-term power needs or RV setups.
Winner: EcoFlow Delta 3 Plus
Although both use high-quality LFP cells, the Delta 3 Plus offers longer lifespan and far greater expandability, making it the more versatile long-term energy solution.
Power Output and Appliance Compatibility
The EcoFlow Delta 3 Plus delivers a powerful 2,400W AC output and supports X-Boost mode up to 5,000W, enabling the operation of high-wattage appliances such as electric stoves, dryers, and large air conditioners. With a robust 15-port array, it accommodates multi-device usage effortlessly.
The Anker SOLIX C1000 is rated for 1,800W continuous output with a 2,400W surge, enough to handle devices like microwaves, power tools, or CPAP machines. While its output is slightly lower, it remains capable of powering most household and mobile appliances. It includes 11 ports, including dual 100W USB-C and full-sized AC outlets.
Winner: EcoFlow Delta 3 Plus
The higher output capacity and powerful X-Boost feature make it the better option for users with high-demand appliances or whole-home backup needs.
Charging Speed and Solar Input Performance
The Anker SOLIX C1000 impresses with its 1,300W AC charging input, recharging the unit from 0–100% in just 58 minutes. This places it among the fastest in its category. Its solar input capacity reaches up to 600W via XT60, making it suitable for off-grid solar setups when paired with portable or rooftop panels.
The EcoFlow Delta 3 Plus, however, supports 2,200W AC input, enabling 0–80% recharge in 50 minutes, despite having a much larger internal capacity. More notably, it supports up to 1,600W solar input, giving it significant advantages in solar-only energy systems and faster replenishment during daylight hours.
Winner: EcoFlow Delta 3 Plus
Faster charging via both AC and solar, plus higher input ceilings, give the Delta 3 Plus a clear lead in charging versatility.
Portability and Design
The Anker SOLIX C1000 is compact and lightweight at 12.9 kg, making it one of the most portable high-output power stations available. Its streamlined form factor and durable handle make it easy to carry for van life, job sites, or emergency grab-and-go situations.
The EcoFlow Delta 3 Plus, in contrast, weighs a substantial 33.5 kg, more than double the weight of the SOLIX C1000. While it includes ergonomic side handles, the unit’s bulk makes it better suited for stationary use in homes or semi-permanent off-grid setups.
Winner: Anker SOLIX C1000
For users who prioritize portability and compactness, the SOLIX C1000 is the more manageable and travel-friendly unit.
Connectivity and Smart App Control
Both units offer full app-based control via Wi-Fi and Bluetooth, allowing users to monitor input/output status, control charging, enable power-saving modes, and update firmware remotely. The Anker App is intuitive and stable, providing basic functionality in a clean interface.
The EcoFlow App is more feature-rich and supports integration into EcoFlow’s broader Smart Home ecosystem, including compatibility with the EcoFlow Smart Home Panel. This makes it a stronger candidate for users building advanced energy systems that can manage entire circuits or automate power routing during grid outages.
Winner: EcoFlow Delta 3 Plus
Its deeper ecosystem integration and smart home capabilities make it the better choice for advanced users and residential energy automation.
