The power of a car battery in the palm of your hand
These powerful lithium-ion Jump-Starters will easily jump-start your car, truck, boat, or tractor up to ten times before they need to be recharged. Easy to use, if you connect the jumper cables to the battery incorrectly, red light and audible tone alert you of the condition and won’t let electricity flow. When correctly connected, they illuminate green - showing that they are ready to use. The IonBoost V8 Jump-Starter delivers an incredible 800 peak amps and 400 cranking amps. Each Power Bank features two USB ports that are rated at 3 and 2.1 amps and can be used to power and recharge your phone, tablet, and most USB devices. Jump-Starters easily recharge via any USB outlet or with the included cable and 12v adaptor. Padded storage case keeps the Jump-Starters ready to use and measures only about 9"w x 7"l x 3"d, small enough to fit in your glove box.
