Anker SOLIX C300 DC 288Wh Portable Power Station: A Full Review

I spent last weekend camping off the grid with three dead headlamps, two dying phones, and a drone that needed juice, which forced me to rethink my portable battery setup. Most heavy-duty backup power units are massive bricks that take up half a car trunk, but the Anker SOLIX C300 DC goes the opposite route. It looks like an oversized Bluetooth speaker and weighs practically nothing for what it holds inside. If you only need to run USB devices and 12V car accessories, this might genuinely be the best power station for the money right now.

It packs a 288Wh lithium iron phosphate (LiFePO4) battery, meaning it'll handle thousands of charge cycles before degrading. You get a ridiculous amount of USB-C power here—two ports push out 140W each, easily keeping a pair of MacBooks fully charged while you work from a picnic table. There are seven ports in total, including a standard 12V car socket for air pumps or portable fridges.

The catch? It's strictly DC power. There are no standard AC wall outlets on this thing, which means you can't plug in a regular lamp or a coffee maker. Anker also doesn't include a wall charger in the box; you have to use your own USB-C brick to charge the solar generator itself. But by stripping out the heavy AC inverter, Anker managed to make this unit 30% smaller than competitors. For a dedicated tech-charging hub on the road, it hits a really sweet spot between price, portability, and raw capacity.
