The JS-15000N lithium powered vehicle jump starter/power bank is a powerful, portable device capable of jump starting automobiles, charging mobile devices and lighting your way through the dark. Only slightly larger than a cell phone, this power bank can fit anyway and retain its charge for a year without needing to be recharged. With two USB ports located beneath the water tight cover at the back of the charger, this product is more than capable of charging two phones at once. The jump start function on the JS-15000N is simple to use and takes no time at all to deploy. To jump a vehicle, simply plug the jumper cables into the battery pack, connect the clamps to your battery and start your car. The only thing more convenient than that is the fact that it will jump start a car up to 20 times on a single charge. The JS-15000N also features a powerful LED flashlight with three modes (high, low and strobe) to ensure that you are prepared no matter what situation you find yourself in. To make it even easier to use, these chargers are equipped with a digital display that clearly illustrates the battery status and output display to let you know how much battery life you have left. Included is a 19 V 3.5 A output adapter and charging tips for charging laptop computers as well as dual charging cords for apple and android devices. It even has a convenient storage case for the jump starter and all of its accessories. With hook and loop straps and molded plastic inserts, the power kit can be kept neat and organized until it is ready to use.
