- Fast Charging: Roughly 1.5 hours for a full charge, 80% in about 50 minutes according to Anker.
- Versatile Connectivity: Seven outputs for numerous devices, from smartphones to smaller household appliances.
- Durable LiFePO₄ Battery: High cycle stability and a five-year manufacturer's warranty underscore the quality.
Design & Technology
The Anker SOLIX C300 has a functional, understated design. With dimensions of 6.4 × 6.3 × 9.4 inches and a weight of 9 lbs, it is easy to carry thanks to an integrated handle. Anker specifies a plastic housing without an official IP rating; the manufacturer describes it as robust enough for everyday outdoor use, but it is not certified against dust or splashes.
While the C300 is designed for outdoor use, its lack of an IP rating means it's not officially protected against dust or splashes. Exercise caution in extreme weather conditions.
The heart of the SOLIX C300 is a LiFePO₄ battery. This chemistry is known for high cycle stability and a long lifespan compared to conventional lithium-ion cells. Anker backs this with a five-year warranty. The 288 Wh capacity is enough, based on manufacturer figures, to charge an average smartphone roughly 20–25 times or a laptop 3–4 times, depending on the device.
Connectivity is generous for the size: the SOLIX C300 offers seven outputs in total, typically covering multiple USB-A and USB-C ports, one or two AC outlets rated up to 300 W, and a 12 V DC output. Anker specifies a full charge in about 1.5 hours from a wall outlet and roughly 80% in 50 minutes via the built-in fast-charge mode.
The quoted 50-minute charge to 80% is enabled by Anker's proprietary HyperFlash technology and is a manufacturer specification. Real-world results depend on outlet, cable and ambient temperature.
Practical Use
Based on Anker's published specs and independent hands-on coverage, the C300 is aimed at low- to mid-draw devices: small coolers, LED lighting, fans, drones, laptops, cameras and phones. The 300 W AC output is not designed for high-wattage appliances such as kettles, coffee makers, hair dryers or space heaters.
Do not attempt to power high-wattage appliances (e.g., kettles, coffee makers, hair dryers, space heaters) with the SOLIX C300. Its 300 W AC output is insufficient and could damage the device or trip its overload protection.
Simultaneous multi-device use is straightforward thanks to the seven outputs, and the display shows charge level, input and output power, and estimated remaining runtime. Under low load the unit is described as near-silent in reviews; the internal fan spins up when the AC output is pushed close to its 300 W ceiling, but the reported noise level remains moderate for outdoor or occasional indoor use.
Solar recharging is supported via a separately sold panel. Anker lists compatibility with common portable solar panels; under strong sun, the C300 can act as an off-grid power source, though full charge times will depend heavily on panel wattage and conditions.
To get the most out of the C300 on the go, pair it with a compatible Anker or third-party solar panel that matches its DC input voltage range. This is what makes the unit genuinely grid-independent.
When estimating remaining runtime, pay close attention to the display. It dynamically adjusts based on current input and output, providing a more accurate real-time estimate than fixed calculations.
Overall, the C300 is positioned as a portable power source for smaller consumers, not as a whole-home backup. Users who need to run high-wattage appliances should look at higher-capacity models in Anker's lineup or from competitors.
