Those little 12-volt pumps are neat, but rigging out the cable from the cigaret-lighter plug is a pain, especially if you want to fill the wheelbarrow tires when the wheelbarrow tires when the wheelbarrow is flat down in the garden. Air Shot has its own internal battery, inflates a car tire in about four minutes, can be used as a 12-volt power pack and recharges from your cigaret lighter or 110-volt outlet. You can also use the Air Shot to inflate bicycle tires, basketballs, sovver balls and other kid stuff. In fact, you may have a hard time wrestling it away from the kids to adjust your air shocks. Keep it in the garage or carry it in the car. About the size of a lunchbox, Air Shot weighs 7.5 pounds. It’s $89.95 from Airshot Inc., 4530 South Berkeley Lake Rd., Norcross, GA 30071; 404-236-8346.
