The Weego 70 Jump Starting Power Pack is a compact, 3-1/2 lb jump starter that delivers 700 cranking amps and features a bypass button that allows users to jump a completely dead battery. It's rated for large gas engines (10L+) and smaller diesel engines (5L+). With advanced voltage detection, the 70 can recognize a lead acid battery as low as 0.5V and provides voltage support to raise and maintain the voltage of the vehicle’s battery to a level safe for jump starting. The Weego 70 also doubles as a portable power source for recharging USB devices such as a smartphone or tablet as well as 12V tools and accessories.
