Portable power stations have become one of those products that seem indispensable once you start reading about them. Jackery, EcoFlow, Bluetti — there’s a whole category built around the idea that you need a dedicated battery bank to keep the lights on during a storm or charge your phone at a campsite. Some of those products are excellent. They’re also $150 on the low end, closer to $400 if you want real capacity, and they require their own charging ecosystem. If you already own Ryobi ONE+ tools, you may already have most of what you need. The Ryobi 18V ONE+ 150W power source costs $49 as a bare tool and snaps directly onto the batteries you already own. It changed how I think about portable power.
