Frequently Asked Questions (FAQ)

What is the most common accessories abbreviation for charging?

USB-C with PD (Power Delivery) is the most common combination today. It charges everything from earbuds to laptops.

What does "dongle" mean in accessories abbreviations?

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.

What is the difference between Thunderbolt and USB-C?

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.

Which abbreviation should I look for in a power bank for my laptop?

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.

What does "OTG" mean?

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.

Are all USB-C cables the same?

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.

What is the abbreviation for a docking station?

There is no single abbreviation, but look for "docking station" or "hub" with ports like HDMI, DisplayPort, USB-C PD, RJ45, and USB-A.
