A 288Wh LFP station for small AC and USB loads, combining a 300W inverter, three AC outlets, 140W two-way USB-C, app control, and a built-in light in a 9.1-pound case.

## Verdict

It is a smart apartment, garage, or car-camping companion for modest loads; buyers who expect cooking, heating, or long outage runtime should move up at least one capacity class.

## Review

The AC-version C300 earns its place by being small without becoming USB-only. Its 288Wh LFP battery feeds three AC outlets, high-power USB-C, a car socket, and a built-in light, which makes it useful for routers, laptops, camera gear, phones, and low-draw medical devices after checking their actual consumption. Fast wall charging and an under-10ms transfer mode add genuine household utility.

The 300W inverter is also a firm boundary. This is not a kettle, heater, induction-cooktop, or power-tool station, and the 100W solar ceiling limits how quickly it can recover away from the grid. Owner discussions also point to inverter standby consumption and the importance of understanding pass-through behavior. The C300 is best when the buyer defines a modest load list before relying on it.

## Why we considered it

The Anker SOLIX C300 AC packs three AC outlets, high-power USB-C, a light, fast charging, and UPS behavior into a compact 288Wh station for apartments, garages, and short trips.

## Why it missed the ranked list

Its 300W inverter, 100W solar ceiling, meaningful idle draw with AC enabled, and limited runtime make it a specialist small-load option rather than a broadly capable backup pick.

The C300 was considered because it is one of the smallest stations that still offers a convincing mix of AC outlets, fast USB-C, lighting, and UPS behavior. It missed the top 10 because the main list gives more weight to sustained appliance capability and useful outage runtime. The C300 is excellent at a narrower job, but that job stops at small loads.

## What stands out

- Three AC outlets in a 9.1-pound case
- 140W two-way USB-C charging
- Built-in light and fast transfer behavior

## Tradeoffs

- Only 300W of rated AC output
- Solar input is limited to 100W
- Leaving the inverter active reduces useful runtime

## Best for

- Apartment electronics backup
- Garage and garden power
- Car camping with modest AC loads

## Not for

- High-wattage appliances
- Long off-grid stays
- Ultralight travel

## Key product facts

- **The AC-version SOLIX C300 provides 288Wh capacity, 300W rated AC output, eight output ports, and 140W two-way USB-C charging.** The exact A1722 product page and manual define the hardware, while an independent field article confirms the practical value of its mixed AC and USB port selection.
- **The C300 can switch to battery power in under 10 milliseconds, but its 100W solar limit and 300W inverter keep it focused on electronics and other small loads.** Official documentation establishes the transfer, charging, and output limits, and independent testing frames the realistic router, laptop, lighting, and short-duration backup role.
