Pros & Cons

Pros

288Wh LiFePO4 pack gives a little more capacity than RIVER 2 and EB3A
300W AC output plus strong USB-C makes it a tidy laptop, phone, router, and travel station
Anker's battery ecosystem and warranty posture are reassuring in the small premium tier

Cons

100W solar input is only adequate for light-duty camping recovery
Not enough inverter for kitchen appliances, power tools, or refrigerator startup loads
Premium small-station price can overlap discounted 500Wh models

Runtime Fit

Using an 85% planning assumption for AC loads, SOLIX C300 offers roughly 245 usable watt-hours before reserve and real-world variables. Treat it as a compact backup for phones, router, lights, laptop charging, and carefully verified CPAP use. Runtime changes with actual watts, duty cycle, battery age, temperature, and whether you use AC or DC output.

Output And Surge

SOLIX C300 is listed at 300W continuous output with 600W surge-class headroom. Capacity answers how long the station may run. Output answers whether the load starts at all. Check refrigerator compressors, pumps, power tools, and cooking appliances before treating any estimate as reliable.

Recharge And Solar

The published solar-input figure is 100W, and AC recharge is listed around 1.1 hours. Solar panels rarely deliver nameplate wattage all day, so plan around realistic sun, panel angle, weather, and the station's voltage/connector requirements.

Who Should Buy It

SOLIX C300 makes the most sense for budget, camping, cpap buyers who understand the limits of its capacity tier. Buy it when the load matches the station. Size up when refrigerator, CPAP, RV, jobsite, or home-panel expectations exceed the Wh, surge, weight, or recharge envelope.

Our Verdict

The SOLIX C300 is the polished small pick for USB-C-heavy users. Buy it for portable electronics and modest CPAP planning, not for household appliance backup.

How We Chose This Pick

Frequently Asked Questions

Can the SOLIX C300 run a refrigerator?

Not as a primary refrigerator plan. It may help with electronics and small loads, but fridge startup and runtime need a larger station with more surge headroom.

Can the SOLIX C300 run a CPAP overnight?

Only with exact-device verification and a conservative setup, usually humidifier and heated tubing off if that is acceptable for the user.

Is the SOLIX C300 a whole-home backup system?

No. Treat it as a portable essentials station, not a whole-home backup system.

Can the SOLIX C300 replace a UPS?

Do not assume that. Some stations offer UPS or EPS-style behavior, but transfer time, waveform, supported load, and medical/device tolerance are model-specific.
