That’s why laptop charging is a new topic of conversation for USB connections, especially now that more laptops are entering the market with USB-C charging compatibility. This type of connection now provides enough power to juice up most laptops ( particularly the Type-C 3.0 version). However, prior versions of USB could handle a limited amount of power, which is why laptop chargers have typically retained their larger, bulkier cables. That works well because past USB connections had enough wattage to successfully power up those smaller batteries. You have probably already used USB connections to charge smaller devices either from your computer or from an outlet.
