Data from official source

The Anker SOLIX C300 is a lithium iron phosphate power station, meant to live in a backpack or on a car seat rather than in a corner at home: it has no expansion battery, so the capacity it starts with is the capacity it keeps.

The USB-C port both accepts and delivers power through the same input, so a single cable serves both to recharge the unit and to power a laptop with heavy draw. Connected to the outlet, it switches to battery fast enough that a computer left on doesn't notice the outage. Remaining charge reads on its own screen, without opening the app; the phone stays useful for finer settings, like automatic shutoff.

It stays quiet at arm's length, comfortable to keep running while sleeping in a tent or working in a van. It suits anyone looking for a light reserve for a phone, lights and a laptop during a trip or a shift away from home; anyone looking for a reserve to run a fridge during a power outage at home needs more capacity than this.

The rest of the data comes from one page on the manufacturer's site, cited row by row in the table above.

A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.

03 · Summary

Pros and cons

In favour

The same USB-C port recharges the unit and powers a demanding laptop, without needing two different cables.
Connected to the outlet it acts as a safety net: if the power goes out, a connected laptop doesn't shut down.
It stays quiet at arm's length: it can be kept running close by while sleeping in a tent.
It shows remaining charge on its own screen, without needing to open the app to check it. source

Worth knowing

The starting capacity is final: no expansion battery exists for this line.
Above continuous power it relies on brief peak support, not a full and constant output.
The automatic shutoff time can only be adjusted from the app, not from the buttons on the unit. source
