Ask experts about the "smart selection" of charging cables in the telecommuting era

Telecommuting that spread rapidly as a result of the coronal disaster. There has also been an increase in work outside the workplace and charging cables must be carried. It should be noted that the charging cable always works comfortably.

The coronal disaster increases the chances of carrying cables with you.

A lot of cables

After the corona, the rapid spread of remote work. In 2021, there will be more and more scenes of working outside the workplace, and more and more people will carry computers, tablets, smartphones, Wi-Fi routers and so on. This is followed by a lot of charging cables. But how much do you care about the charging cable?

It's easy to buy long things before you know it.

First of all, the most important thing of the charging cable is the length. There is a proverb: "big and small". As for the cable, too long will reduce the charging efficiency. Because the longer the resistance, the more difficult it is for the current to flow, so it takes longer to charge than in the case of the same performance. It is important to see the length that suits your environment and choose something that is no longer than you need.

The charging time should be as fast as possible.

I want to charge busy hours effectively in a short time. If there is such a need, you will want to choose the cable that says "corresponding to fast charging", but be careful when using this. Even if you use a "fast charging" cable, the charging speed will not necessarily be faster. In fact, in order to maximize the power of the cable, the adapters in the upstream of the power flow and the machines themselves downstream of the receiving electricity, that is, devices such as mobile phones, must be charged quickly. The conditions of "fast charging" from upstream to downstream are available in order to enjoy the speed.

5 V 3 A

So what should I choose? Cable boxes, adapters, etc., contain supported power, etc. When charging a smartphone, using a regular USB cable ensures a voltage of 5V (volt), so the current is at least 2.4A (ampere). If possible, you can choose a product with 3A, and you can charge quickly when the power consumption is more than 15W (watt). In addition, if there are multiple cable jacks on the adapter, using only one is faster than using two at the same time.
