Reversible USB port

Reversible USB port [Copy link]

 

 

I bought a mobile power board a few days ago. I didn’t think much of it at first, but later I found that the USB A port was quite special. It can be plugged in both ways.

The height of ordinary USB2.0 and USB3.0 is 5.7mm

The height of the positive and negative insertion is slightly higher

Which generation of USB does this belong to?

I've heard of it before, it seems to be the innovation of Huaqiangbei

Then there should be a certain gap when inserting it, right?

The A port is plugged in reverse! I hope it can be popularized

There is a gap

In the future, USB 4.0 will be used and the old USB 2.0 interface will be gradually phased out.

I have always had a question in my mind, why is the USB not designed to be round, so that I don’t have to worry about the problem of plugging it in the right or wrong way?

A circular data port may be more difficult to design and increase costs. There are currently circular magnetic charging ports, one that can only charge, and one that supports data:

My thoughts were hasty.

But the gap doesn't seem to be big. Will it break easily if it is only fixed by the middle column?

This is innovation.

Maybe in future applications, they will be replaced with this or with tpyeC

I tried it and it seems fine. As long as you don't damage it intentionally, it shouldn't be a big problem.

I don't know where to buy it.

Round ones are easy to squash, but flat ones are flat.

This is an idea from many years ago. Not only does it have a socket, but it also has a plug and a microUSB.

It was used a lot on power banks before, but it didn’t become popular.

I will use Type-C from now on.

Well, actually it was the mobile phone industry that impacted it, and they all unified on typec

Unification is also a good thing. You don’t have to carry a bunch of wires, and the price is also reduced.
