The 12V Jump Starter Power Bank is a beast of a power bank because it can jump start a vehicle 20 times or more on a full charge! Now that’s power! Not only does it support a 12V vehicle jump start but it charges most electronics such as: cell phones, media players, PDA, laptops and more. It will even charge multiple devices simultaneously. With the power bank, you get home and car chargers and cell phone adapters for the most popular cell phone and laptops. Non-sparking technology provides an additional level of safety and an LED indicator detects if clamps are connected correctly. The voltage-smart safety clamps automatically shut-off to prevent sparking, reverse polarity or battery damage and a lithium battery provides longer shelf life. The power bank has a 12V output for vehicle jump and other 12V automotive devices; a 19V output to recharge laptop computers; and a 5V USB port to charge various model cell phones. It comes in a handy carrying case.
