Detailed overview: Anker Solix C300X DC 288Wh USB-C portable power station
The Anker Solix C300X DC is a compact 288 Wh (90,000 mAh) portable power station that takes the opposite approach to classic models: it is designed for direct current and USB-C, with no inverter and no 230V mains socket. This choice has two concrete consequences. First a lighter, more compact format, easy to carry, complemented by a supplied carry strap. Then better efficiency: by powering your devices directly over USB-C or 12V, it avoids the losses of conversion to 230V, which extends real-world runtime.
Its 288 Wh battery uses LiFePO4 (lithium iron phosphate) chemistry, known for its safety and longevity. Its trump card is USB-C connectivity: it offers four 140 W USB-C ports, several of them bidirectional (which also serve to recharge it quickly), enough to power up to four devices at once, laptop included. To this are added a USB-A port and a 12V output. A built-in light proves very handy outdoors or during an outage.
It recharges from the mains, in the car or via a compatible solar panel, ideal for staying self-sufficient for several days camping or on the move. On this partner site, it is often offered with a 60 W portable solar panel, for turnkey charging in the sun.
Compact, light and 100% USB-C, the Anker Solix C300X DC is aimed at campers, videographers, remote workers and travellers who want a reliable energy reserve for their USB and 12V devices, without the burden of an inverter-based station. Just check that your devices charge over USB-C or 12V before buying.
Comparison
At around 250 to 400€, the Anker Solix C300X DC compares with compact USB-C-focused power stations and DC stations, targeted by searches such as "USB-C power station" or "camping power station". Here is how it sits against three references: the EcoFlow TRAIL 200 DC, the Anker Solix C300 (AC version) and the EcoFlow RIVER 2.
| Criterion | Anker Solix C300X DC | EcoFlow TRAIL 200 DC | Anker Solix C300 (AC) | EcoFlow RIVER 2 |
|---|---|---|---|---|
| Capacity | 288 Wh | 192 Wh | 288 Wh | 256 Wh |
| 230V mains socket | No (100% USB-C/DC) | No (pure DC) | Yes (300W) | Yes (300W) |
| USB-C | Four 140W ports | 140W + 100W | 140W | 100W |
| Light / strap | Light + strap | Light (optional) | Built-in light | No |
| Observed price | ≈ 349 € | ≈ 149 € | ≈ 230 € | ≈ 249 € |
In short, the C300X DC stands out for its four 140W USB-C ports, a record for this format, ideal for charging several demanding devices at once. The TRAIL 200 DC shares the same DC philosophy for less, but with less capacity and fewer ports. The AC C300 adds 230V sockets for the same capacity. For a 100% portable use centred on USB-C, the C300X DC is the most complete, provided you do not need a mains socket.

Our tester's review: Christophe Delpuech
The C300X DC takes the opposite approach to classic small stations: here, no mains socket, everything goes through USB-C, and it is remarkably effective. You plug the phone, tablet and laptop straight into its 140W ports, with no inverter, which avoids losses and extends real-world runtime. With four 140W USB-C ports, you charge a MacBook at full speed while powering three other devices, real comfort in remote work or a van. Its 288Wh in a compact format slip easily into a bag thanks to the supplied strap, and the built-in light comes in handy while camping or during an outage. Solar charging lets you stay self-sufficient for several days. Two honest caveats: the absence of a mains socket restricts it to USB and 12V devices, you cannot plug in a small 230V appliance, and 288Wh is a backup capacity. But to charge your portable devices fast and loss-free, in a light and versatile format, it is an excellent choice.
