🔌 Charger
Discover the Charger!
A Charger is used for filling up the battery inside your devices with power.
🔌 How Does a Charger Work?
Electricity from a wall socket is very strong and keeps changing direction, which would damage a phone. A charger changes it into a small, steady flow that a battery can safely store. A tiny chip inside your device talks to the charger and slows the charging down as the battery gets close to full, so it does not overheat.
🌟 Fun Facts about Charger
- A charger sends electricity from a wall outlet into your device’s battery.
- Many devices today use USB cables to charge.
- Fast chargers can fill up a battery more quickly than regular ones.
- It’s a good habit to unplug your charger when it’s not being used.
🌟 Where You'll Find a Charger
Every home has chargers for phones, tablets, laptops and toothbrushes. Some phones and watches charge without a plug at all: you just rest them on a wireless charging pad, which uses magnets and coils of wire to send energy across a tiny gap.
