About Anker SOLIX C1000

The Anker SOLIX C1000 is a game-changing modular portable power station that grows with your needs. The base unit has 1056Wh of LiFePO4 battery capacity and 1000W of AC output (2000W surge with SurgePad), but here's the magic: you can stack up to 3 extra battery packs on top for a total of 4224Wh — no cables, no complicated setup, just stack and go. The modular design means you can start with just the base unit for camping and weekend trips, then add batteries later when you need more capacity for longer off-grid stays or home backup. Anker's legendary build quality and reliability are here too, with a 5-year warranty and premium components throughout. Charging is fast — 0-100% in just 58 minutes via wall outlet, which is incredibly fast for a 1kWh station. Add in the 12 output ports, smart app control, and optional solar charging up to 400W, and the SOLIX C1000 is one of the most versatile and future-proof power stations available.

Key Features

🔋

Modular Expandable Battery

1056Wh base LiFePO4 battery that can be expanded by stacking additional SOLIX C1000 Expansion Batteries. Each adds 1056Wh, up to 4 total (4224Wh). No cables — just stack and they automatically connect. Start small, grow as needed.

58-Minute Fast Charging

HyperFlash technology charges the base unit from 0-100% in just 58 minutes via standard wall outlet. That's faster than most small phone power banks! Even with 2 batteries stacked, it charges in under 2 hours.

🚀

1000W with SurgePad

1000W continuous AC output with SurgePad technology that handles surges up to 2000W. Powers high-startup devices like refrigerators, window AC units, and power tools that would trip other 1000W stations.

🔌

12 Output Ports

Plenty of ports for everything: 4x AC outlets, 2x USB-C (100W PD each), 2x USB-A (12W), 1x USB-A fast charge, 1x carport (12V/10A), 2x DC 5521. Power up to 12 devices simultaneously.

Frequently Asked Questions

How does the modular stacking work?

It's really simple — each expansion battery pack has connectors on the top and bottom. You just set one on top of the other, and they automatically connect electrically. No cables, no setup, no pairing. The system automatically recognizes the added capacity and adjusts charging/discharging accordingly. The stack stays stable with alignment pins and magnets.

Can I add batteries later?

Absolutely! That's the whole point of the modular design. Start with just the base station if that's all you need today, then buy expansion packs later when you need more capacity. They're sold individually, and you can add up to 3 extra packs for 4 total (4224Wh).

How does it compare to EcoFlow Delta Pro?

The EcoFlow Delta Pro has much higher base capacity (3600Wh vs 1056Wh) and higher output (3600W vs 1000W), but it's also much more expensive and heavier. The Anker SOLIX C1000 is a better choice if you want to start smaller and have the flexibility to grow, or if you value portability when you don't need maximum capacity. For whole-home backup, Delta Pro is better. For flexible use cases, SOLIX C1000 is more practical.

Is it good for home backup?

With 1056Wh base and up to 4224Wh expanded, it can provide meaningful home backup for essential devices during outages. A single base unit might last a few hours to half a day running essentials; fully expanded to 4224Wh, you could power critical circuits for a day or more. It's not a whole-home solution, but it's excellent for essential device backup and much more flexible than fixed solutions.
