• Innovative technology with no internal battery so no need to wait hours for the unit to charge before use. • Simple and safe to use with no long term battery storage issues. • Can be fully energised in approximately 2 minutes. • If the vehicle battery is faulty or is holding less than 5 volts the E/START800 can be pre-charged via another vehicle's battery, the supplied Micro USB charging cable or the 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.
