We own a small business that's 12 miles from the nearest city. We have a lot of equipment, such as tractors, backhoe, zero turn mowers, and personal vehicles. Batteries are constantly needing charging, and this Battery Jump Pack is perfect. It sure beats a plug-in heavy-duty charger needing an electrical outlet, especially when the nearest outlet is 600 feet away. We've used it several times in the week we've had it, even charged our -I phones. A neighbor used his to jump start our backhoe, that's when we knew we had to have one. One our best investments ever, plus we got it on sale. This would be great for people who get stuck in snow and their battery dies. Don't leave home without it!
