Mini-USB vs. USB Power Delivery
Comparing 2 standards across 8 specifications. 8 key differences identified.
Mini-USB (Mini-B) was a compact 5-pin connector common on digital cameras, MP3 players, and the original PlayStation Portable in the mid-2000s. USB-IF deprecated the Mini connector family in May 2007, and Micro-USB replaced it in nearly all subsequent compact-electronics designs.
USB Power Delivery (USB PD) is a separate negotiation protocol governing how much power flows over a USB-C cable -- independent of the cable's data speed. Standard Power Range tops out at 100W (20V/5A); PD 3.1's Extended Power Range (2021) raised that ceiling to 240W (48V/5A), requiring cables with a built-in identification chip.
