Ryobi ONE+ 18V 150W Power Source

The Ryobi RYi150BG converts the 18V DC power of any ONE+ battery into 120V AC, the same current that comes out of a household wall outlet. It is an accessory, not a self-contained power station: you supply the battery, it supplies the socket. The unit clips onto any battery in the ONE+ lineup, from the smallest compact packs up to the largest high-capacity ones, and turns on with a press-and-hold of the power button.

Output is 150 watts continuous through a single 120V outlet, enough for charging electronics, running a small fan or lamp, or powering low-draw tools and gadgets. Two USB ports add charging for phones and tablets without needing the AC outlet at all, and a built-in LED light rounds out the feature set for use during a power outage or after dark outdoors.

Runtime depends entirely on the battery attached. A 4.0 Ah ONE+ battery, a common size in the lineup, runs the unit for roughly 20 to 30 minutes at full 150W output, but stretches to several hours at the lower draw of charging a phone or running a small light. The real advantage over a dedicated power station shows up when you already own several ONE+ batteries for your drill, saw, or other tools: swapping in a fresh one takes seconds, with no waiting on a charge cycle.

The RYi150BG does not charge the battery, it only draws from it, and Ryobi does not publish the output waveform, so it is best paired with everyday electronics rather than sensitive equipment or medical devices. For anyone already invested in the ONE+ ecosystem, it is one of the cheapest ways to add a backup outlet to a tool bag, truck, or emergency kit.
