Black & Decker JUS500B 500 Amp Jump Starter
If the Black & Decker JUS300B appeals to you but you have concerns about the cranking amp rating, the JUS500B is a potential solution. This model is only slightly bigger than its lower-powered sibling, yet maintains the attractive low-profile design and portability entirely.
All of the features of the JUS300B are present, from the reverse polarity alarm to a bright built-in light to illuminate your work area in dim lighting. The battery in this unit can also be kept charged using the built-in AC charger which plugs into a standard household 110-volt wall outlet. This model is suitable if you own a heavy-duty truck, or if you live in an area with a cold climate which requires additional cranking amps to reliably start your car.
