-- Plug the charger into the wall and use it to charge a battery.

         electrical energy  ===>  chemical energy

After that:

-- Use the battery to run my electric trimmer and trim my beard.

           chemical energy  ===>  kinetic energy

OR . . .

-- Use the battery to operate my phone when I'm out of the house.

           chemical energy  ===>  back to electrical energy

OR . . .

-- Use the battery to run my little pocket radio when I'm jogging

            chemical energy  ===>  sound energy

OR . . .

-- Use the battery to run my hand-warming-gloves while I shovel snow
