Product Details: 

• 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.
