ONE+ delivers more value with cordless convenience when you need it most. The RYOBI® 18V ONE+™ Dual Function Inflator/Deflator provides high pressure inflation for tires and other small inflatables and high volume inflation for large inflatables. The easy-to-use controls allow automatic shut-off at any pressure you choose and there is a digital pressure read-out for accurate inflation. All of the hoses, nozzles and adaptors needed are stored on-board for your convenience. The 18V ONE+™ Inflator/Deflator is sold as a bare tool, allowing you to build on your ONE+™ collection without spending additional money on batteries and chargers with each tool purchase. Best of all, like every RYOBI® 18V ONE+™ blue or green tool, this Inflator/Deflator works with any 18V ONE+™ battery. Upgrade to lithium-ion or LITHIUM+™ batteries for lighter weight and better performance.
