“Weego’s Crankenstein Jump Starting 12V/24V Power Pack provides 1,200 cranking amps and 5,000 peak amps for 12-volt systems and 600 cranking amps and 5,000 peak amps for 24-volt systems and is engineered to jump-start 0-volt batteries safely and automatically. An OLED screen walks users through the jump and communicates warning messages and connection quality, while a built-in voltmeter measures battery voltage. The company’s Connection Detection technology displays the quality of battery terminal connections, and its Hotfoot technology allows operation in temperatures from – 28 to 140 degrees Fahrenheit. The 9-pound unit’s lithium phosphate battery is engineered for stability during jumps requiring durability and resistance to potential overheating situations.”
