The SP Tools USA Next Generation Ultra-Capacitor Jump Pack, No. SP61074, utilizes ultra-capacitor technology and allows a vehicle's flat battery, with at least 5V available, to charge the jump starter's capacitors and then jump start the vehicle. Simply connect the jump starter to the vehicle battery; it will display the vehicle batteries' existing voltage and health status and, if necessary, can then charge itself from the depleted vehicle battery. Once charged, the SP61074 is then able to supply a short burst of full power back into the vehicle's electrical system, allowing for vehicle start up. Capacitors can fully charge in 45 seconds. The SP61074 is able to jump start gasoline engines up to 5L and diesel up to 3L.
