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.
