This is a teaser from Frank Curzio of Phase 1 Investor at Stansberry Research. He has the name of the company that has the technology that allows these small batteries to put out enough cranking power to start a car, presumably with a dead battery. I am not sure if they actually tested them on a ”dead” battery. It seems the manufacturer-Powerall, simply claims that this device can start your car. I may have missed the part that it can actually start your vehicle by jumpstarting a ”dead” battery, which is why we have and use jumper cables.
