Unboxing and First Impressions
The Anker SOLIX C300 DC portable power station arrived in a compact package. Included were the unit itself, a USB-C to USB-C cable, and the user manual – everything you need to get started. The device's matte finish feels solid and durable, and it has a surprising amount of weight for its size, hinting at its substantial battery capacity.

Measuring approximately 6.5 x 6.3 x 9.5 inches and weighing around 9.1 pounds, the C300 is surprisingly portable. The integrated nylon handle enhances portability, making it easy to carry and transport.
The overall design and build quality are impressive, giving a sense of reliability and longevity, which is further emphasized by the use of high-quality materials.
Specifications and Features
The Anker SOLIX C300 boasts a 288Wh battery capacity, powered by a Lithium Iron Phosphate (LiFePO4) battery. LiFePO4 batteries are known for their superior longevity, reliability, and safety compared to standard lithium-ion batteries.

With an output power of up to 300W (600W peak), this compact powerhouse can easily charge a wide range of devices, from smartphones and laptops to drones and even small appliances.
Its extensive port selection includes two 100W USB-C ports, one 140W USB-C port, one 15W USB-C port, two USB-A ports, and a 120W car socket. The addition of a solar panel input port expands its versatility for off-grid power solutions.
Performance and Testing
During testing, the Anker SOLIX C300 effortlessly charged multiple devices simultaneously, including laptops, phones, and other gadgets. I even connected a USB hub to expand the charging capacity, highlighting its ability to handle a substantial power draw.

The integrated digital display accurately reflects the remaining power and estimated time left, dynamically adjusting as devices are connected and disconnected. The real-time power usage information is incredibly helpful.
I even tested charging power-hungry appliances like a mini-cooler and a space heater, and the C300 performed flawlessly, maintaining steady power output without overheating.
Pros and Cons
The Anker SOLIX C300 shines in its portability, high-wattage USB-C ports (perfect for fast charging), multiple charging options, a long-lasting LiFePO4 battery, and smart app connectivity. Its excellent ventilation keeps it cool even under heavy load.
On the downside, the lack of AC outlets requires adapters, and the included USB-C cable isn't sufficient for maxing out the high-wattage ports. Solar charging performance may vary depending on conditions.
Conclusion and Recommendation
The Anker SOLIX C300 is an excellent portable power station, offering an impressive balance of portability, power output, and charging versatility. While the price point is competitive within the market, it's a worthwhile investment for users needing robust and reliable on-the-go power.

The high-wattage USB-C ports are a game-changer for fast-charging laptops and other high-drain devices. However, buyers should consider the necessity of purchasing a higher-quality USB-C cable for optimal performance and consider the lack of AC outlets.
Overall, this power station is a robust and reliable option that delivers excellent performance and value. Although a bit pricey, it's a top contender within its class, offering a blend of convenience, efficiency, and long-term reliability.
