You can inflate all the tires on the car and then some with the Worx 20V Power Share Portable Inflator. It fills up 4.5 tires on one charge. And it goes from 0-36 psi in about 4 minutes per tire. That's faster and more efficient than inflators from other brands. And you don't have to plug it into your car's DC port and then park some place that's convenient to use it. Take it to the pool, the dock, even pack it for a long bike ride, it's the ultimate in portability and convenience. The LED lamp outputs 100-200 Lumens and can be used as a work light so you can see what you're doing, a flashlight if you need to take a walk in the dark to a service station, even an emergency beacon to alert other motorists that you need assistance. The flexible 3-foot hose lets you reach nozzles and stems that are hard to get at, and it comes with 3 adaptors: 1 sports ball needle, 1 Presta and bike valve adaptor, 1 tapered adaptor for small inflatables like pool toys. Plus, the soft-grip handle is comfortable to hold and use for long stretches. Keep the Worx 20V Power Share Portable Inflator in your trunk and gain the peace of mind you get from being prepared. This model does not include a Worx Power Share battery or charger.
