How do you charge a phone
This depends on the phone brand. Most modern phones have wireless charging that allows phones to be placed on a charging mat or pad. Some phones require you to plug them in. Plugs for phones vary by manufacturer. Apple for instance has used a proprietary charging system called lightning for years but recently was sued and now will have to comply with an industry standard of using USB-C to charge their phones.
