To recharge means to restore energy or power to something that has run down or been depleted. When your tablet's battery gets low, you plug it in to recharge it. The device draws electrical power until it's full again and ready to use.

The word works for people too. After a long week of school, tests, and activities, you might need to recharge by spending a quiet weekend reading, playing outside, or hanging out with your family. Athletes recharge between games with rest and good meals. Your brain needs to recharge after intense studying, which is why taking breaks actually helps you learn better.

You can also recharge a rechargeable battery, like the ones in a wireless game controller or a flashlight. These batteries can be used, recharged, and used again many times, unlike regular batteries that get thrown away when they're empty.

The word suggests filling something back up to its full capacity, like refilling a water bottle or restocking a pantry. When you feel worn out and then do something that makes you feel energized again, you've successfully recharged.
