Anker SOLIX C1000
1056 Wh · 1800 W output · LiFePO4 · $999
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
The default recommendation for most people. It clears the 1kWh bar, recharges in under an hour, and undercuts almost everything with comparable specs.
Best for: First-time buyers who want one unit for camping and short outages without overpaying.
What we like
- Full recharge in 58 minutes — fastest in its class
- 600W solar input is unusually high for 1kWh
- Expandable to 2kWh later if your needs grow
Where it falls short
- 2400W surge won't start a sump pump or well pump
- Only 1056Wh — a fridge-plus-devices outage tops out around a day
