Socket Extension Lead With USB-A Port

This is the most common type of USB port built on the multi socket extension lead. You may find many of them in parallel, each of them being able to deliver 1A or 2.1A (some older versions at 0-2.1A), according to the need of attached devices. These are the same 5V USB ports on your laptop or desktop computer. Most devices in life only use this power, for example, mini fans, desk lamps, toys, electric toothbrushes, etc.

Its advantage over a 5V USB-A is significant; a QC3.0 USB-A port charges four times faster and is charge an average battery from 0 to 80% complete in one hour.

First launched by USB-IF in 2012, USB Power Delivery (PD) is now in its 3.0 version, which technically supports charging power up to 100W through a USB-C port and does not limit the compatible devices to phones, tablets, and laptops. It will also include other multimedia equipment in the list. Unlike QC3.0, which only applies to devices with Qualcomm chips, USB-PD is universal and more inclusive. The iPhone is currently using the PD charging protocol. For example, iPhone 8 and later models can support PD fast charging with proper accessories. Using multiple socket extension lead with USB PD charging can achieve 50% charging in half an hour and 80% in one hour.
