• Output: 800A (Peak), 400A (EN).• Innovative technology, which unlike traditional boosters does not require an internal battery as a primary power source but incorporates a lithium battery pack to energise unit when vehicle battery is not sufficient to energise capacitors.• Simple and safe to use with no long term battery storage issues.• Can be fully energised in approximately 2 minutes.• Digital display indicates battery voltage, capacitor charge and faults.• If the vehicle battery is faulty or is holding less than 5 volts the E/START800HY can be pre-charged via an internal lithium battery pack, another vehicle's battery, a Micro USB charging cable (not supplied) or 12V accessory lead.• Compact and lightweight for easy handling and storage, yet still delivers the same result as heavy, bulky, lead acid battery equivalents.• Ideal for the professional mechanic and DIY users.Vehicle jump starting made easy with innovative technology. Unlike traditional boosters it does not require an i
