One of the most common problems that we all encounter in our homes is the fact that we have a large number of power adapters or transformers stored in many of our drawers and cabinets. The current goal is to find a universal charger, which has been achieved with cell phones and micro-USB. However, it is the USB-C 2.1 and sus 240W those who promise the universal charger.
Think about it, it’s 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 recharge the controller of our video game console, the mobile phone, a vaper or electronic cigarette and even a portable screen. However, USB-C’s charging level 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 in our homes to end up using this connection as a power source as well.
The first 240W USB-C cables appear
USB-C cables with a charging capacity of 240 W achieve this thanks to 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 be long before we see devices like laptop, monitors and future iterations of some dessert consoles It’s included external graphics cards.
The advantage of USB-C cables is that they don’t just transmit data and power the device they’re connected to. One capability it has over older USB types is video transfer. As a result, not all 240W USB-C cables are 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 primarily a charging cable, since its transfer speed is that of a USB2.0 and therefore only 480 Mbps. Besides, missing Alt-DP mode to stream the 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 video capabilities, it can reach 4K and a refresh rate of 60Hz.
- The last type is CAC-1576Which is also USB4 and has a transfer rate of 40 Gbps at 3×2. Its video capability is 8K@60Hz, so you have 4 times the bandwidth in that regard. Its downside? The cable is only 1 meter long, against 2 meters in the other two cases.
Let’s not forget that the new cable will also require a completely new power supply, the one that plugs into the wall socket, and the old ones cannot be used. In any case, one wonders if the houses of the future will have USB-C connectors integrated into the wall sockets. Who knows, only time will tell.
