The SIP 1000A 12v Capacitor Booster is an innovative handheld portable device designed to discharge a high current boost needed to start a larger car or van battery. Offering powerful performance in a compact unit, the 1000A Capacitor Booster is ideal as a safeguard for home users which can be easily stored or a quick and easy solution for small automotive workshops. Starts up to 5ltr petrol engines or 3ltr diesel engines. How does it work? By connecting the positive/negative clamps from the capacitor unit to the terminals of a flat battery, the capacitor cell absorbs remaining voltage in around 90 seconds. A single touch 'on' button initiates power transfer and a digital display indicates the unit is 'preparing' then 'ready' to deliver boosting current to the vehicle. Applications & uses: Perfect for larger cars and vans, home or small automotive workshop use, and starting up to 5ltr petrol engines or 3ltr diesel engines.
