Fewer Cords, More Batteries

This is an electrical cord.

We plug many things in with electrical cords.

We plug cords into cars to charge them.

We plug cords into phones to charge them, too.

But sometimes, we trip over cords.

And if cords get wet, it can be very dangerous!

And also, cords are too short sometimes.

And this is why batteries are important.

With a battery, she doesn’t need an electrical cord to talk on the phone.

And with a battery, she can use her computer on the beach.

And with a battery, he can raise his video game controller when he wins his game.

Of course, there are still so many cords that we need today.

And even this wireless charger needs a cord.

For example, this TV looks like there are no cords.

But behind the TV, there are many cords.

There are so many cords in the back of the TV.

When they put the TV on the wall, they hide the electrical cords.

All the time, there are fewer and fewer cords.

And more and more things have batteries in them.
