The portable power station market has split into two camps: massive units that power a small house during a power outage, and compact units that keep devices charged during a camping trip or travel day. The Anker Solix C300 is definitely the second kind, but it’s also powerful enough to keep small appliances and other essentials working in a pinch. It’s also at its lowest price in months at Amazon, with a fast-moving 23% off deal dropping it to just $230.
The C300’s 288Wh LiFePO4 battery delivers 300W of continuous output with a 600W surge, which covers laptops, cameras, drones, CPAP machines, and small appliances — the kind of gear that needs real power rather than just a USB port. That’s more than just a convenient backup — that’s a major peace-of-mind investment for a very minor price. You can double down on that by adding the C300’s solar panel for another $80 to make it a bundle that earns its keep during just one lengthy outage.
Eight Ports of Power
The port layout is where the C300 dunks on simpler battery packs. Three AC outlets deliver 300W total for anything that plugs into a wall. Two 140W USB-C ports handle fast charging for laptops and phones simultaneously — and those same ports work bidirectionally, meaning you can recharge the station itself at 140W via USB-C PD 3.1. A third USB-C at 15W, a USB-A at 12W, and a 120W car socket round out the options. Eight ports across four connection types means you’re not choosing which device to charge — you’re charging all of them at once.
The C300’s LiFePO4 cells handle 3,000 charge cycles before meaningful degradation, which translates to roughly a decade of regular use. They’re also more thermally stable, which reduces fire risk and allows the C300 to run its smart temperature control system at just 25 dB — quiet enough to run next to a tent at night without disturbing anyone sleeping nearby. The lesser chargers and their lithium-ion batteries can’t compete.
Road Ready
The C300 is roughly 15% smaller than comparable units, which matters when it’s sharing space in a car trunk or a camping pack with everything else. It’s a hair over 9 pounds, and the sold-separately carrying strap makes it seem even lighter. Measuring in at just 9.45 inches high by 6.46 inches long and 6.34 wide, it easily earns a spot in your RV, trunk, or any other mode of transportation.
Wall charging gets the C300 to 80% in 50 minutes, and solar charging works with Anker’s 100W or 60W panels for sustainable off-grid recharging. The $310 bundle with the solar panel is worth considering for anyone planning trips where wall power isn’t available — buying the panel separately later typically costs more. With or without the solar panel, this Amazon deal on the Anker Solix C300 is beyond solid, if just for the peace of mind you’ll get from a powerful yet abundantly portable backup.
