Detailed overview: Anker Solix C300 DC 288Wh USB-C portable power station
The Anker Solix C300 DC is a compact 288Wh (90,000 mAh) portable power station that takes the opposite approach from classic models: it is built entirely around direct current and USB-C, with no inverter and no AC outlet. That choice has two concrete benefits. First, a lighter, more compact format, easy to carry, complemented by an included carry strap. Second, better efficiency: by powering devices directly over USB-C or 12V, it avoids the losses of converting to AC power, which stretches real-world runtime.
Its 288Wh battery uses LiFePO4 (lithium iron phosphate) chemistry, known for its safety and longevity. Its trump card is USB-C connectivity: four USB-C ports, two of them bidirectional up to 140W (which also serve to recharge it quickly), a third up to 100W and a fourth up to 15W, enough to power up to four devices at once, laptop included. A USB-A port and a 12V output round out the connectivity. A built-in light proves very handy outdoors or during an outage.
It recharges from the wall, in the car or via a compatible solar panel, ideal for staying self-sufficient for several days camping or on the move.
Compact, light and 100% USB-C, the Anker Solix C300 DC is aimed at campers, videographers, remote workers and travelers who want a reliable energy reserve for their USB and 12V devices, without the bulk of an inverter-based station. Just check that your devices charge over USB-C or 12V before buying.

What is this power station best for?
-
Camping & Tent Ideal
Designed for the outdoors, the C300 DC is a 100% USB-C and 12V station, with no inverter or conversion losses: its 288Wh power a 12V cooler, LED lighting and fans with excellent efficiency, and its powerful USB-C outputs up to 140W recharge phones, tablets and a laptop directly. Ultra-light (2.8 kg) and silent, it slips into a bag and recharges up to 100W from solar. Ideal for a lean camp built around 12V; however, with no household outlet, it can't run any conventional AC appliance, coffee maker or hot plate included.
-
Hiking & Bivouac Suitable
At just 2.8 kg, the C300 DC is one of the few stations light enough for a backpacking base camp: it acts as a charging hub for headlamps, GPS units, smartwatches, camera batteries and phones, with very fast USB-C outputs up to 140W. Its 288Wh of LiFePO4 last several days on measured needs, and a solar input up to 100W recharges it at camp with no outlet at all. Its lack of an inverter limits losses and maximizes usable energy for mobile devices, exactly what you want far from the grid.
-
Road trip & Car Suitable
Built around 12V, the C300 DC is an ideal road-trip companion: it recharges while driving from the car's 12V socket and keeps a cooler and your devices cold and charged at stops and overnight. Its powerful USB-C outputs up to 140W quickly fill phones, tablets and a laptop, and its lack of an inverter maximizes efficiency on these devices. Ultra-light (2.8 kg), it stows anywhere in the cabin. For long successive nights without driving, a small 100W solar panel extends its runtime; its 288Wh remain modest for heavy needs, however.
Our team's recommendations based on the model's capacity, output power and weight.
Comparison
At around $200, the Anker Solix C300 DC competes with compact USB-C-focused and pure-DC power stations, the kind shoppers search for as "USB-C power station" or "DC power station". Here is how it sits against three references: the EcoFlow TRAIL 300 DC, the EcoFlow TRAIL 200 DC and the EcoFlow TRAIL Plus 300 DC.
| Criterion | Anker Solix C300 DC | EcoFlow TRAIL 300 DC | EcoFlow TRAIL 200 DC | EcoFlow TRAIL Plus 300 DC |
|---|---|---|---|---|
| Capacity | 288 Wh | 288 Wh | 192 Wh | 288 Wh |
| AC outlet | None (100% USB-C/DC) | None | None | None |
| USB-C | Four ports (2x140W + 100W + 15W) | 140W | 140W | 140W |
| Battery chemistry | LiFePO4 | LiFePO4 | LiFePO4 | NCM |
| Observed price | $199.99 | $143.10 | $109.00 | $189.00 |
In short, the C300 DC stands out for its four USB-C ports, two of them up to 140W, a rare setup in this format, ideal for charging several demanding devices at once, plus a sturdier LiFePO4 battery than the TRAIL Plus 300 DC's NCM cells. The TRAIL 300 DC and 200 DC undercut it on price with fewer ports. For fast, loss-free USB-C charging, the C300 DC remains the most complete choice.

Our tester's review: Christophe Delpuech
The C300 DC takes the opposite approach from a classic small station: no AC outlet at all, everything runs through USB-C, and it's remarkably effective. You plug a phone, tablet and laptop straight into its 140W ports, with no inverter, which avoids losses and stretches real-world runtime. With four USB-C ports (two up to 140W, one up to 100W, one up to 15W), you can charge a laptop at full speed while powering three other devices at once, real comfort while working remotely or on the road. Its 288Wh in a compact format slip easily into a bag thanks to the included 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. One honest caveat: the absence of an AC outlet restricts it to USB and 12V devices, you can't plug in a small household appliance. But to charge portable devices fast and loss-free, in a light and versatile format, it's an excellent pick.

No. It's 100% direct current: it powers devices through four USB-C ports (two up to 140W, one up to 100W, one up to 15W), a USB-A port and a 12V output, but has no AC outlet. This choice makes it lighter and more efficient for portable devices.
Yes, and even several devices at once. With its two USB-C ports up to 140W, it charges a laptop at full speed while powering a phone, a tablet and another device in parallel on the other two ports (100W and 15W).
From the wall, in the car or via a compatible solar panel, letting you stay self-sufficient for several days.
Any device that charges over USB-C or 12V: phones, tablets, laptops, cameras, drones, small pumps. Its 288Wh make it an ideal backup reserve for camping or remote work.
