Jump Starter Available here. A jump starter is a device that provides the surge of power required to start a flat car battery. Jump starters connect to the car battery terminals using jump leads and once turned on, provide power to the car battery in order for it to turn on. Noco jump starters can start a dead car battery in seconds and are ultra safe, providing a powerful jump start but also protecting the battery and the user. Portable jump starters are excellent to have in the car for an emergency and are very easy to use, ensuring almost anyone could jump start a car safely. Jump starters now double up as emergency power banks, providing a charge to your phone and other essential items via the USB ports.
