UCB450-30, 15 Volts 90 Farads Capacitor onboard Jump Starter 900 Peak Amp Current for Cars, Trucks, Engine Ignition for sub-Zero Temperature, Car

The UCB450 is a versatile product that boosts engine starting and improves vehicle electric systems, especially high amperage requirements of aftermarket audio systems. It also reduces draw on batteries that operate electric appliances such as refrigerators, TVs and more. The product has a potential drawback of some power leakage, like all capacitors. The module comes complete, and the individual components used in the product are not listed. The UCB450 can be stacked for higher amperage output. It is not waterproof, but it works fine unless blasted with a high-powered pressure washer. Those who did not do any voltage testing had observed improvements in engine performance running smoothly and faster acceleration. The product seemed to be durable and built like a tank, according to one client who employed it as a current inrush surge reducer on a lithium lifepo4 battery that runs a refrigerator. They also appreciated that the on/off switch allowed them to avoid capacitor charge sparks when hooking up wires to the battery. One review suggested that the product might be better than adding a second battery to cars.
