A watt is 1 Joule per Second (1 J/s). E.g. Every second, your device draws 1 Joule of energy. This energy over time is called “Power” and is a rate of energy transfer.

A watt-hour is (1 J/s) * (1 hr)

This can be rewritten as (3600 J/hr) * (1 hr). The “per hour” and “hour” cancel themselves out which makes 1 watt-hour equal to 3600 Joules.

1 kWh is 3,600 kJ or 3.6 MJ

That’s why you operate multiple brands. You’ve got your Walmart brand and your decent brand and your overpriced luxury brand all pumped out of the same overseas factory
