Need a jump starter? This is one of the most advanced models in the world that requires no maintenance just put it in your car and forget about it. Normal jump starters have batteries need regular maintenance and charge and are big and heavy. This model has no battery inside. Made with latest models of ultra capacitors which have long life cycle of 10 years with no maintenance. Plus they are 100% safe with no danger of explosion or fire.
Battery-less jump starters draw only 0.2-0.4Ah energy from the battery. A weak car battery normally has a capacity of 10-30Ah and can recharge the jump starter many times without any side effects. Easy - when you car battery is low and will not start the car just charge the starter from your weak battery and then start the car. Usually takes 100 seconds for the starter to charge. Even if the battery is too weak to start the car it will have enough to charge the starter. If your battery is completely empty - you can charge the starter from another car battery or from a USB.
