Detailed Review
Overview
The Anker SOLIX C300 enters the compact power station market with a clear advantage over budget competitors: Anker’s engineering pedigree in charging technology. Most notable is the 60W USB-C PD output, which is significantly faster than the 30–45W PD ports seen on competing 300Wh-class units. This means faster charging for modern laptops, tablets, and high-power USB-C devices without the need for an AC adapter.
At 7.7 lbs and with a slim profile, the C300 is genuinely portable — it fits in a camera bag side pocket or a carry-on bag, and the handle makes one-handed transport effortless.
Capacity and Runtime
The 288Wh capacity is honest about what it can and can’t do. You’ll get 5–6 full laptop charges, 20+ smartphone charges, or 4–5 hours running a 60W device continuously. Plug in a small drone charging hub and you can turn around 6–8 batteries per charge cycle. For a mini cooler pulling 45W, expect roughly 5 hours of runtime.
This isn’t the right unit for overnight appliance duty — for that, step up to a 1kWh station. But for day-use portable power with high-speed USB-C output, the C300 excels in its class.
Charging Speed
AC charging refills the C300 in about 1.5 hours from a wall outlet. Solar charging accepts up to 100W, which fills the battery in roughly 4 hours under optimal conditions. Car charging via the 12V/24V input is available for top-ups on the road.
The C300 supports pass-through charging, allowing you to power a device while simultaneously recharging the station — a useful feature when power is intermittent.
Who It’s For
The SOLIX C300 is ideal for photographers, videographers, and content creators who need reliable, fast power for their kit in the field. It’s also an excellent travel companion for remote workers who need a laptop backup, and a practical emergency charging station for home outage kits. Anker’s quality and the class-leading USB-C output set this apart from cheaper alternatives at similar price points.
