Forget driving over the lawn, or pushing a non-starting car out to a place where you can run jumper cables to a dead battery. And that’s if you have a second car available for the jump-start. This convenient jump-starter will start a car with a dead battery in seconds, by boosting your battery with its own internal battery. As a bonus, it’s a great source of 12V power in an emergency or on the jobsite, including not only a 12V lighter plug but also a 5V USB socket for charging laptops or cell phones. With reverse polarity protection, it’s impossible to hook it up backwards and damage your battery or vehicle’s fragile electronics. It recharges readily from an ordinary household extension cord, or by plugging it into the 12V power outlet in your running vehicle. As a bonus, there’s a swiveling LED work light that will make it easy to use underhood. Consider one for camping, for lighting near the tent, and power a radio while you charge your cellphone. Who said camping was roughing it? It’s also a reassuring source of emergency power during power outages.

Black & Decker is the 300-lb. gorilla of portable power tools, and since they patented the hand-held portable pistol-grip electric drill in 1916, it’s no wonder. They’ve also pioneered the cordless tool revolution, while maintaining industry leadership in the corded tool market. While Black & Decker tools are manufactured in 11 countries, they are marketed in more than 100.
