Is it okay to use 100 uniform cables on USB Type-C cable?

The USB cable that connects a personal computer and peripheral device needs to be carefully selected

A series that understands the complex strange standard and the USB Type-C.This time, let's unravel the four mysteries related to the cable.[Visual commentary] Is USB Type-C, 100 uniform cable OK?

■ Q: Doesn't the speed decrease depending on the type of cable?

I couldn't find the attached cable of the portable SSD, so I used a Type-C cable for smartphone charging behind the drawer.Is there a problem?Ariari problem.If you make a mistake here, high -speed USB devices such as SSD become treasures.If the cable support standard is lower than SSD, it will be a bottleneck.The cable standard should pay the same attention as the USB terminal of a personal computer and device.For example, if the terminals of the personal computer and SSD are USB4, the cable will not reach the USB4 speed unless it is USB4 compatible.Be careful when using high -speed equipment such as portable SSDs.On the other hand, if the cable standard is higher than the USB device standard used, you can use the surplus cable.For example, even if the PC side is a USB4 terminal, there are 2 devices to connect..If 0, 2.0 cables are OK.However, the higher the standard, the higher the price of the cable, so when purchasing a new cable, we also want to consider the equipment standard.And it is important to organize cables anyway.In particular, if the Type-C cable is taken out of the package, it may be in a no-hint state.It is good to attach a label that wrote the USB standard.

■ Q: There is no problem with the 100 Type-C cable?

The recent 100 yen uniform shop (100-yen shop) sells Type-C cables.I'm glad that you can get an item that costs more than 1000 yen for a mass retailer for 100 yen, but I'm worried about "cheap or bad".I verified the 100 uniform cable.What I want to pay attention to is power supply ability.It was about 2A when the current was measured with a 100 uniform cable that sang up to 3 amp (A).Type-A specifications for 2A (up to 1).It is a point because it exceeds 5a).For charging applications such as smartphones, I felt that the 100-percent Type-C cable had a good merit.I also used it to connect Type-C terminals for PC PD and PD compatible mobile batteries.Then, the current was about 2A and the voltage was about 20V, and I was surprised that it worked properly as a USB PD.By the way, the package of the cable does not say PD support.For more than 60 watts (W) cables that claim PD compatible, a IC chip called "EMARKER" described later is required.I checked the transfer speed of the SSD, but this was out of the question.2 on the package.There are cables with 0 corresponding descriptions and cables that are not, all of which are less than 50MB/sec.100 Type -C cable 2.It may be considered as a standard.There is no reason to use it aggressively for data transfer.The 100 uniform cable has a low price by eliminating the emarker chips mentioned above.In addition to USB PD, 3.This chip is indispensable for 2 GEN 1 or more.
