It’s a frustration that many a car owner has experienced at some point in his or her driving lifetime. You stick the key into the ignition, give it a turn, and get nothing but noise. Or even no noise at all. Great, another dead battery.

You could call up roadside assistance and wait a couple hours for them to arrive. You could grab a typical battery booster pack, but that means you need to pop open the hood in the cold outside. You could ask for a jump from a friendly neighbor, but that requires going outside too.

Much simpler than any of these solutions is the Glove Box Battery Jumper. As its name implies, this product is small enough to fit in your glove compartment. Simply plug it into your 12V outlet and it’ll trickle charge your car battery in about ten minutes. Give the ignition a go and you’ll be back on the road.

This means you never have to leave the driver’s seat. When you are back on the road, flip the switch to reverse the current, and your car’s battery can be used to recharge the internal battery on this jumper. Pretty neat. Find it at Hammacher Schlemmer for $34.95.
