Detailed overview: Anker Solix C300 288Wh portable power station
The Anker Solix C300 is a compact 288Wh portable power station that packs a lot of function into a very small footprint. Its battery uses LiFePO4 (lithium iron phosphate) chemistry, a mark of safety and longevity, well suited to regular use camping, working remotely or as occasional backup at home.
Despite its small size, it does not skimp on versatility: three 120V household outlets deliver 300W continuous, raised to 600W thanks to SurgePad technology for start-up surges. Its standout feature is a bidirectional 140W USB-C port, which charges a laptop at full speed and also serves to quickly recharge the station itself. Two more USB-C ports, a USB-A port and a built-in light round out the connectivity, the light proving handy outdoors or during an outage.
On comfort, it is remarkably quiet at just 25 dB measured at 1 metre, pleasant indoors even at night. Recharging is fast for its category: 80% in 50 minutes from a wall outlet, or up to 100W on solar. A retractable handle eases transport.
Compact, complete and quiet, the Anker Solix C300 suits anyone looking for a small, versatile power station for camping, outdoor leisure, remote work or occasional backup power, with the reliability of LiFePO4 chemistry and a USB-C port powerful enough for a laptop.

What is this power station best for?
-
Camping & Tent Ideal
Ultra-compact (4.13 kg) and very quiet (25 dB), the C300 is built for the tent: its 288Wh and built-in ambient lamp light the camp, while its three household outlets and, above all, three USB-C ports up to 140W recharge phones, tablets and even a laptop at night. Its 300W output (600W peak) covers small devices, a fan or a mattress pump included. Rechargeable to 80% in 50 minutes and up to 100W from solar, it tops up at camp in good weather. LiFePO4 chemistry (3000 cycles) and a 5-year warranty make it a reliable reserve season after season; large cooking appliances remain beyond its 300W.
-
Remote work Suitable
For occasional work away from the office, the C300 handles the essentials: its three USB-C ports up to 140W fast-charge a laptop and a tablet, and its 300W output powers a router or hotspot for hours. Its 288Wh suit a morning of work or a video call in a backyard, a van or a co-working spot with no outlet nearby, and its UPS function (10ms switchover) shields the setup from brief power blips. Very light (4.13 kg) and quiet (25 dB), it travels without a second thought. Its modest capacity keeps it to light work; a dual-monitor setup or a printer calls for more.
-
Road trip & Car Suitable
In the car or at a rest stop, the C300 keeps devices charged without draining the vehicle battery: its three USB-C ports up to 140W refill phones, a tablet and a laptop, and its 300W output runs a small cooler or a fan at a campsite stop. At 4.13 kg it rides easily in the trunk, and its 100W solar input tops it up during a scenic stop. Quiet at 25 dB, it won't disturb a nap in the back seat. For a multi-day trip with heavier loads, pair it with a larger station.
Our team's recommendations based on the model's capacity, output power and weight.
Comparison
At around $330, the Anker Solix C300 competes with compact power stations near 300Wh, the kind shoppers search for as "portable power station" or "camping power station". Here is how it stacks up against three alternatives: the Jackery Explorer 300, the EcoFlow RIVER 3 and the Bluetti Elite 30 V2.
| Criterion | Anker Solix C300 | Jackery Explorer 300 | EcoFlow RIVER 3 | Bluetti Elite 30 V2 |
|---|---|---|---|---|
| Capacity | 288 Wh | 292 Wh | 245 Wh | 288 Wh |
| AC output | 300W (600W peak) | 300W | 300W (550W peak) | 600W |
| Max USB-C | 140W | 100W | 100W | 100W |
| Observed price | $329.99 | $259.00 | $239.00 | $399.00 |
In short, the Anker Solix C300 stands out for its 140W USB-C port, well ahead of this comparison, along with quiet operation and a built-in light. The Bluetti Elite 30 V2 pushes harder on AC output for more money, while the Jackery and EcoFlow undercut it on price with less USB-C headroom. For a small, complete and versatile station, the C300 remains a strong all-rounder.

Our tester's review: Christophe Delpuech
We tested the Solix C300 for its format above all: three real household outlets, a 140W USB-C port that charges a laptop at full speed, and even a built-in light for camping or an outage. Its 300W output (600W in SurgePad mode) covers most small appliances, and we especially like how quiet it runs, at 25 dB you forget it completely on a nightstand or desk. Charging is fast for the category, 80% in fifty minutes on a wall outlet, and the 140W USB-C port doubles as a quick way to recharge it. The retractable handle and small footprint make it a true pocket station you grab without thinking twice. Two honest caveats: 288Wh is a backup capacity, perfect for USB devices, a mini fridge or an evening, not for several days on end, and solar input tops out at 100W. For a compact, complete and quiet station, it remains a strong value.

Yes. Its bidirectional 140W USB-C port powers most laptops at full speed. It also has three 300W household outlets (600W peak) for other devices.
Yes, remarkably: just 25 dB measured at 1 metre, making it pleasant indoors, even at night on a nightstand or desk.
From a wall outlet, it reaches 80% in 50 minutes. On solar (input up to 100W), expect roughly 2.5 hours to 80%. The 140W USB-C port also works to recharge it.
Its 288Wh and 300W suit phones, laptops, a mini fridge, a lamp or small appliances. It is a backup capacity, ideal for an outing or an evening, not for several days straight.
