The output voltage of this circuit diagram is 12V AC, which is suitable for the low voltage power supply device of the lamp inside the lamp. This circuit does not have a voltage regulation characteristic, so be careful when using it.
Emphasis: Because of the market chaos and the cheating of bad dealers, most people simply don't understand USB 3.0 and USB 3.1. USB 3.1 Gen1 is USB 3.0. And USB 3.1 Gen2 is the real USB 3.1. The maximum transmission bandwidth of USB 2.0 is 480 Mbps (i.e. 60MB/s), USB 3.0 (i.e. USB 3.1 Gen1) is 5.0 Gbps (500MB/s), and USB 3.1 Gen 2 is 10.0 Gbps (although the nominal interface theoretical rate of USB 3.1 is 10Gbps), but it also retains some bandwidth to support other functions, so it has a good performance. The actual effective bandwidth is about 7.2 Gbps. USB 2.0 is a four-pin interface, and USB 3.0 and USB 3.1 are nine-pin interfaces.
USB 3.1 is the latest USB specification, which was initiated by big companies such as Intel. Compared with the existing USB technology, the new USB technology uses a more efficient data encoding system and provides more than twice the effective data throughput (USB IF Association). It is fully downward compatible with existing USB connectors and cables.
USB 3.1 is compatible with existing USB 3.0 software stacks and devices

Intel, which owns Thunderbolt technology, also welcomes the formation of the USB 3.1 standard. USB 3.1 contains most of the features of USB 3.0 [2]. USB 3.1, as the next generation of USB transmission specifications, is commonly referred to as "SuperSpeed+", which will replace USB 3.0 in the future. [3]
