With this potent pair of power tools on board, changing a tire takes but a fraction of the time and far less effort than the old way. InstaJACK plugs into your vehicle's cigarette lighter or 12-volt power outlet. Raises and lowers with the push of a button – no cranking or levers. A built-in light illuminates your work area and fold-out mirrors let you see under your vehicle without having to lie down to see where to position the jack. Retractable wheels make positioning InstaJACK a snap. Jack range lifts from 5" to 17-1/2" and lift capacity is 7,000 lbs. – plenty for most cars, vans, SUVs and light trucks. This combo also comes with the InstaWRENCH impact wrench. It also plugs into any 12-volt vehicle power port and supplies up to 250 ft.-lbs. of torque. Forget about slipping conventional lug wrenches, busted-up knuckles or banged-up shins. InstaWRENCH will remove your wheel's lug nuts in seconds, and without the hassle or potential hazards. Two ergonomic handles give you maximum control, and a built-in light shines right on the area you need to be working on. It comes with interchangeable sockets – 11/16", 3/4", 13/16" and 7/8" (17, 19, 21 and 23mm) – that will fit the lug nuts of most vehicles. Together, the InstaJACK and InstaWRENCH make changing a flat a cinch for almost any driver. The combo comes in a convenient hard-plastic carry case and also includes a 12-volt socket adapter to let you have both tools plugged in at the same time – another time-saving innovation.
