The reversible design is also a major plus, eliminating the frustration of trying to plug in a cable the wrong way.
A Word on Micro Universal Serial Bus and Mini Universal Serial Bus
While prevalent on older devices, Micro Universal Serial Bus and Mini Universal Serial Bus standards are largely obsolete for laptop charging. Their power capabilities are far too limited, and they are rarely, if ever, found on modern laptops as charging ports.
Decoding Universal Serial Bus Power Delivery
Universal Serial Bus Power Delivery, often shortened to Universal Serial Bus Power Delivery, is a game-changing technology that allows universal serial bus connections to transfer significantly more power than older universal serial bus standards. This is achieved through a more sophisticated communication protocol between the charging device (like your laptop) and the power source (like a wall adapter). This communication allows the power source to intelligently adjust the voltage and amperage it delivers, optimizing the charging process and ensuring compatibility.
Universal Serial Bus Power Delivery specifications define different power profiles, typically expressed in voltage and amperage combinations that result in a certain wattage. You might see specifications like five volts at three amps (fifteen watts), nine volts at three amps (twenty-seven watts), or even twenty volts at five amps (one hundred watts). Higher wattage levels are essential for charging laptops, which typically require much more power than smartphones or tablets.
Understanding Universal Serial Bus Power Delivery is paramount when considering charging your laptop via universal serial bus. Without Universal Serial Bus Power Delivery support, the port simply won’t be able to deliver enough power to charge your laptop effectively, if at all.
Identifying Universal Serial Bus Power Delivery Enabled Ports
So how do you know if your laptop has a universal serial bus Power Delivery enabled port? Here are a few methods:
Look for Visual Cues
Many manufacturers will include a small symbol next to the universal serial bus Type C port to indicate that it supports universal serial bus Power Delivery. This symbol often resembles a battery or a lightning bolt.
Consult Your Laptop’s Specifications
The most reliable way to confirm Universal Serial Bus Power Delivery support is to check your laptop’s specifications. This information can usually be found in the laptop’s manual, on the manufacturer’s website, or by searching for your laptop model online.
