We are about to witness a new era of USB power supply. The new USB Type-C revision has just been released. It has some interesting improvements. One of the facts is,USB Type-C will soon be able to provide up to 240W of power. In short, it is enough to power your gaming laptop and almost any other electronic device.

This is all thanks to the new USB Type-C 2.1 revision, of course, the biggest change is the improvement of the 240W specification we have seen. Previously, Type-C connectors were limited to provide a voltage of 20V when outputting a current of 5A, which meant that they could not provide more than 100W of power.
Even 100W for standard laptops or flagship smartscell phoneIt is also impressive, but if you are using a gaming laptop that contains a standard voltage or even overclocked CPU or desktop GPU, then 100W is not enough to keep it running for a long time (not to mention many laptops connected to 100W PD charging heads. Can only get 65W or even lower power).
The new USB Type-C revision can provide up to 48V, 5A power support, which means that 240W peak power can be pulled, and almost all current laptop needs can be powered by a USB cable that will soon become popular. It should be noted, however, that this optional power supply upgrade requires a new extended power range (EPR) cable, not the standard SPR cable we are using now.
This means that SPR cables will soon be replaced by EPR cables. But at the same time, we must understand the fact that devices that do not require that high power supply may still continue to use the existing standard USB Type-C cables on the market, and they can also enjoy the transmission performance improvement beyond the power supply.
