One of the most common problems that we all have in our homes is the fact that we have a large number of power adapters or transformers stored in several of our drawers and cabinets. The current goal is to find a universal charger, something that was achieved with mobile phones and micro-USB. However, it is the USB-C 2.1 and its 240 W those who promise the universal charger.
Think about it, it is an incredible waste of resources that when a device stops working we have to throw away its charger. This is precisely the beauty of USB-C with fast charging capability, which allows us to charge multiple devices with a single cable and adapter connected to the power source.
In this way, we can easily charge the controller of our video game console, the mobile phone, a vape or electronic cigarette and even a portable screen. However, the charge level of USB-C was limited until relatively recently. Which led to the creation of the cable with a capacity of 240 W. Which in the short and medium term will lead many devices that we have at home to end up using this connection as a power source as well.
The first 240W USB-C cables appear
USB-C cables with the 240 W charging capacity achieve this through a voltage of 48 volts and a current of 5 amps. They were announced a few months ago and their appearance on the market is already a fact, so it shouldn’t take long to see devices like laptops, monitors and future iterations of certain tabletop consoles and even external graphics cards.
The advantage of USB-C cables is that they not only transmit data and provide power to the device they are connected to. One capability it has over the old USB types is video transfer. Which makes 240W USB-C cables not all the same and there are three different variants on the market:
- The first of the cables is the simplest of all and is called CAC-1573. It is mainly a charging cable, since its transfer speed is that of a USB2.0 and therefore only 480Mbps. Besides, lacks Alt-DP mode to stream video.
- The second type is called CAC-1575. It is part of the USB 4 standard and can transmit up to 20Gbps in 2×2. In terms of its video capabilities, it can reach 4K and a refresh rate of 60 Hz.
- The last type is CAC-1576Which is also usb4 and has a transfer rate of 40Gbps at 3×2. Its video capacity is 8K at 60Hz, so you have 4 times the bandwidth in this regard. Its disadvantage? The cable is only 1 meter long, compared to 2 meters in the other two cases.
Let’s not forget that the new cable will also need a completely new power supply, the one that connects to the wall socket, and the old ones will not be able to be used. In any case, we wonder if the houses of the future will have USB-C connectors integrated into the wall sockets. Who knows, only time will tell.
