Practical tip: match abbreviations on your device with the accessory's label.
Example: “If your laptop has a USB-C port with PD logo, buy a charger that lists both.”
USB-C with PD (Power Delivery) is the most common combination today. It charges everything from earbuds to laptops.
A dongle is a small adapter that converts one abbreviation port to another. For example, a USB-C to HDMI dongle lets you connect an HDMI monitor to a USB-C laptop.
Thunderbolt is faster and more capable. Every Thunderbolt port uses the USB-C shape, but not every USB-C port supports Thunderbolt. Look for a lightning bolt icon next to the port.
You need USB-C with PD (Power Delivery) and at least 45W output. Without PD, a power bank will charge your laptop very slowly or not at all.
OTG stands for On-The-Go. It allows a phone or tablet to act as a host, meaning you can plug in a USB flash drive, keyboard, or mouse directly into your phone.
No. Some are USB 2.0 (slow charging and data), some are USB 3.2 Gen 2 (faster), and some support Thunderbolt (very fast) or 100W PD (high power). Always check the full abbreviation list on the cable's packaging.
There is no single abbreviation, but look for "docking station" or "hub" with ports like HDMI, DisplayPort, USB-C PD, RJ45, and USB-A.
You have now mastered over 50 essential accessories abbreviations across computers, audio, charging, storage, and networking. The next time you see "65W GaN PD charger" or "NVMe USB-C SSD", you will know exactly what it means and whether it fits your needs.
