The biggest cellular energy delivery business Booster was established in San Mateo, California. Booster directly provides traditional and alternative fuels and fuel to fleet cars, reducing carbon emissions, cutting expenses, and increasing access to renewable fuels. It is a folksy, tech-focused, and sustainability-obsessed company. During fleets' off-peak hours of operation, the energy-as-a-service provider purchases gasoline from the terminal and distributes it right to the fleets.
