Most phones come with a charger when you first purchase them. However, chargers wear out over time and need to be replaced. Wall chargers are one type of charger that you can use to charge your phone. You can find wall chargers at most electronics stores or online. Wall chargers are typically very affordable, especially when compared to other types of phone chargers. Many wall chargers come with multiple charging ports, which means you can charge more than one device at a time and they are easy to use.
