The Anker SOLIX C300 DC is a compact 288Wh LiFePO4 portable power station with 300W sustained AC output and surge to higher levels. It features 7 charging ports: 1× AC outlet (120W max draw), three USB-C ports (140W+140W two-way fast charging + 100W + 15W), and two USB-A (12W each), plus a 120W car socket. Recharges to 80% in ~1 hour via dual PD 3.1 USB-C, accepts ~100W solar input (Anker 100W/60W panels recommended; incompatible with 5V/3A panels), and can top up via car charging. Weighs 6.2 lbs with compact dimensions (7.87"×4.72"×4.89"), making it 30% smaller than comparable units. LiFePO4 cells backed by 3-year warranty. Best suited for light camping, van life, emergency backup, CPAP/medical devices, and frequent travelers who prioritize portability and fast USB-C charging over large AC runtime. Not a whole-home backup solution; limited to ~1 hour of 300W continuous load.
