 USB Type-Cなのに充電が遅い? ケーブルと充電速度の知っておくべき関係

"I heard that the USB Type-C cable had a faster charging speed, but it wasn't charged than expected." "I wanted to charge it in a short time before leaving home ...!"Have you ever experienced?[Image] USB Type-C cable that can be purchased at 100 yen uniform shop Certainly, USB Type-A (USB Standard A) to USB Type-C cable and USB Type-A to Micro USB (USB Micro B)Unlike cables, the USB Type-C to USB Type-C cable with a USB Type-C connector on both ends has become a hot topic because the power supply is up to 100W (currently up to 240W).。However, not all USB Type-C cables support large-capacity power supply.Introducing how to choose a cable that can be charged as early as possible.

What is fast charging?

As the name implies, quick charging refers to a short time charging to a mobile device such as a smartphone or such a specification.As described below, if it is a USB Type-A to USB Type-C cable 1.Things larger than 5a (2).0a, 2.(1A, etc.), USB Type-C cable to USB Type-C cable is the charging standard that supports charging larger than 3A (5A).

Doesn't it matter much?Data transfer speed and charging speed

First, there are various versions of USB standards including USB Type-C, but it is necessary to know that there is no correlation between the version number and the power supply.The USB standard is formulated by an organization called USB-IF (USB IMPLEMENTERS FORUM).USB Type-A, which is currently on the market, USB 2.0 and USB 3.0 and 3.2 Gen2 is USB 2 for USB Micro B (known as Micro USB).0 and USB 3.0/3.There is something compliant with 1.USB 2.The data transfer speed of 0 is up to 480Mbps and the power supply is up to 0..5a (5V 2.5W), USB 3.In 0, 5Gbps and 0 respectively.9a (5V 4.5W).Nevertheless, a mobile device like a smartphone that cannot be used by that alone has appeared, and USB X.In addition to the standard X, a standard called USB Battery Charging Specification (USB BC) has been added.USB BC 1.In 2, the same USB 2.0 Even the standard cable 7.5W (5V / 2.You can charge with 5A).Furthermore, the shape of the connector called USB Type-C was born, and this is a 5V / 1 defined by the USB Type-C Current..5a (7).5W) or 5V / 3A (15W) is the largest power supply.Therefore, in USB Type-C.5W or 15W is considered a "non -rapid" legacy charging speed.The USB Type-C Current is originally USB x.Defined on a different line from the X standard.For example, USB 3.2 Maximum power supply capacity even for cables with GEN2 standards (data transfer speed up to 10Gbps).It can be 5W.Even if the USB Type-C cable, which is high-speed data transfer speed, cannot be charged quickly, it is not necessarily a bad product.
