At 0W continuous, it has an unconfirmed surge rating, so this project does not assume it can start a typical well or sump pump motor. Its 288Wh battery runs a 75W CPAP with a heated humidifier for roughly 2.9 hours and a 100W mini-fridge for roughly 2.2 hours, after a 25% AC-inverter efficiency loss. At $279, that works out to $0.97 per watt-hour. Its maximum solar input is not confirmed in this project's research.
Can the Anker SOLIX C300 DC Run It? (Surge & Runtime Check)
Each row runs this unit's confirmed specs against that appliance's running watts and startup surge, then works out how long the battery would last at that load. Of these twelve: 0 safe, 0 tight, 12 overloaded.

Runtime applies the same 75% AC-inverter efficiency factor used across this site. Where an appliance cycles rather than running flat out — fridges, pumps, air conditioners — the second figure is the longer real-world runtime at its duty cycle. A blank runtime means the unit cannot run the load at all, so there is nothing to calculate. Appliance figures are typical for the class, not measurements of your specific model: check its nameplate where the margin is close.
☀️ Best Solar Panel Setup for the Anker SOLIX C300 DC
| Maximum solar input | 100W — a ceiling, not a target |
|---|---|
| Setup that fills it | 1 × 100W (100W) |
| Realistic output in good sun | about 70W at 70% of rated |
| Full charge from empty | roughly 4.1 hours of direct sun |
That matches the input ceiling exactly. Additional panels beyond this will not charge the unit any faster.
🛒 Shop 100W Portable Solar Panels on Amazon →Check the voltage range, not just the watts. Wiring panels in series adds voltage, and exceeding the charge controller's maximum input voltage can damage the unit even when the total wattage looks fine. We have not verified the voltage window of any individual panel, so confirm it against this unit's specification before buying. How solar input limits work →
Pros & Cons
- Very portable at 2.8kg
- DC output only — no AC inverter, so it cannot power standard wall-plug appliances at all
- 288Wh is a small battery — enough for devices and a CPAP, not for fridges or power tools
Who Should Avoid This
Look elsewhere if any of these matter to you: dC output only — no AC inverter, so it cannot power standard wall-plug appliances at all; 288Wh is a small battery — enough for devices and a CPAP, not for fridges or power tools.
