Anker SOLIX C300
Anker's smallest. 288Wh at $179 with three USB-C ports — aimed squarely at people charging modern devices, not running appliances.
Best for: Content creators and travelers with a bag full of USB-C gear.
Where it falls short:
- 300W output is device-only territory
- 100W solar input
Anker SOLIX C2000
2048Wh at $1299 with fast 70-minute charging. Sits between the C1000 and the F-series without a standout spec of its own.
Best for: Anker loyalists who want 2kWh and fast charging in one box.
Where it falls short:
- 3600W surge trails the DELTA 3 Max's 4800W at a higher price
- 3000 cycles vs 4000 from newer rivals
