A portable cordless compressor for inflating, brad nailing and airbrush work, with a quick-release coupling that fits existing air tools. Inflates a tyre from flat to full in about 80 seconds. A locking regulator sets and holds the output pressure, and an air valve empties the tank after use. A metal wrap stores the hose on board. Useful to keep in the car for topping up tyres on a long drive. Battery system: ONE+ is Ryobi's 18V platform — one battery fits over 200 tools for house and garden. Battery and charger are not included.
