Anker SOLIX C300X (portable power station 300 W with connectivity): our review

A family tent after sunset can become a charging station of its own: a laptop needs attention, phones are running low, and a lamp makes the picnic table useful again. With 288 Wh of stored energy, the C300X belongs in that small-device routine. That reserve suits phones, a lamp, and a laptop, with usable energy depending on what you connect and the losses along the way.

What would you keep powered through the evening? We would prioritize communication, light, and a little work. The laptop can come camping; its inbox could use better boundaries. This model is well placed overall for a deliberately modest role. A focused reserve makes more sense when your packing list has a clear purpose.

The rated output is 300 W, enough for small devices but too limited for an electric kettle. That distinction matters when planning breakfast beside a camper van. Charging your electronics and boiling water belong on separate plans here. Stored energy describes the reserve; output describes the electrical demand the station can support at a given moment.

Keep your expectations practical. Look at the requirements of the devices you intend to connect, including their combined demand when used together. A motor can also need extra power when starting, so its running requirement does not settle compatibility. We see the strongest case in personal electronics and modest lighting, where the intended job matches the stated output without stretching the brief.

The trunk is packed, the tent is tucked beneath a folding chair, and the campsite is still a walk away. At 4,13 kg, this portable battery is light enough to carry in a single hand. Its carrying handle gives that portability a practical foundation. We like the prospect of moving your power supply along with the rest of an ordinary camping load.

That matters beyond departure day. You might want charging near the picnic table in the afternoon, then bring the station into a sheltered location for the evening. Keep it protected from rain and high heat, and charge it in a ventilated area according to the manual. Easy carrying earns its place through ordinary moves like these.

Solar charging compatibility gives you another way to replenish the reserve away from an outlet. The 100 W maximum solar input is modest, suited to a supplemental panel. At a lakeside campsite, a gap between the trees could give a panel access to morning sun while the station stays sheltered.

The maximum is a ceiling, not a promise of what reaches the battery. Sunlight, panel orientation, and the panel itself affect the result. Would your campsite have a useful patch of sun? That is a practical question before organizing a solar setup. Treat this charging option as a way to support small-device use, with room in your plans for clouds and changing shade.

The C300X makes sense when easy carrying and personal electronics define the assignment. A more demanding backup plan deserves a different shortlist. The AFERIY P310 is better suited to home backup and better rated overall. That is the direction to consider when your priorities extend beyond keeping your immediate essentials supplied.

The Jackery Explorer 2000 v2 is better suited to demanding appliances and better rated overall. Start with the equipment you actually need, then choose the station around those requirements. We would keep the C300X on the shortlist for a lamp, communications, and portable work, while giving a broader appliance plan the equipment it calls for.
