In the lessons

In everyday life a charger is the cable and plug for phones, tablets and laptops. In science, it moves electrical energy into a battery, which stores it as chemical energy. In safety lessons: don't charge devices on your bed or under a pillow (they can overheat and start a fire), use the right charger, don't use broken cables, and unplug when done. Phrases: phone charger, plug in the charger, charging cable, car charger.
