The other option for the mobile charger is the 120 volt-cord, but that mode has a lower limit, 12 amps, and in this case, you’re multiplying it times 120.

(This is a bit difficult for people to grasp because it seems like the opposite - more current at the outlet feeding a device with lower capacity - would pose some kind of risk. The Mustang Mach-E has a generous maximum alternating current charging capacity of 10.5 kW, meaning it can draw more power than the F-150 can provide (7.2 kW), so whatever charger we’d use between the truck and the car would have to be rated at 30 amps or lower to avoid tripping the truck’s circuit breaker. We convert higher numbers like these to kilowatts, which is how we get 7.2 kW. The 240 volts multiplied by 30 amps is 7,200 watts. If it helps everyone’s understanding of the many numbers to come, power is measured in watts and is a product of the voltage (likened to an electric form of pressure, measured in volts) and the flow of current, measured in amperes (amps for short). Pro Power Onboard produces 7.2 kW, with a 240-volt outlet rated at 30 amps. To do this, we needed an EV, and while it’s not necessary to match brands, we happened to borrow a 2021 Ford Mustang Mach-E at the right time and set about our experiment charging a Ford with a Ford. ![]() View all 2021 Ford F-150 models for sale near 60606 ![]()
