How to make a charger for 10 devices?

Question

Batteries

Hello! I want to make a charger for 10 devices (5 for apple and 5 for everything else), I saw ready-made solutions , but the price is very high and I want to do it myself.
Now the very essence:
1) I don’t quite understand how to properly make a power circuit, because for ipad / iPhone / iPod you need not just to short-circuit the data + and data- outputs, but as shown on here , and more, you need to do this for each port or enough to make one such circuit and connect 5 ports to it?
2) What do you need to buy in addition to the power supply, wires, usb moms, resistors, cases, fuses?
What I'm thinking of buying:
1) I want to take a power supply unit 5v 20A ( chip and dip ).
2) Instead of 10 usb moms, I want to buy a usb hub for 10 ports, it will turn out more beautiful and neat
3) 10 + 4 (for a fuse) 2A each.
I apologize for any mistakes, if any. I searched for a long time, but I didn’t find anything worthwhile (at an affordable price).

Answer 1

1. IDevices are powered by regular USB. The iPhone charges perfectly from the HTC charger and from the Chinese noname, as long as the cable is native.
2. Judging from item 1, you need a power supply, fuses, diodes, wires, USB connectors.

Answer 2

They charge, but what current do they consume (idevices), just as I understand it, when you plug into the port in which data + and data- are simply connected, the IDevice consumes only 500 mA, and when you connect, for example, an iPad to the original charger, it consumes 1.5 -2 A. I have a hub for 7 Dlink ports, it has 2 ports connected to the power supply, the iPad is charged from it, but slower than from the original charge, although its power supply is 3A.

Answer 3

Here the guy just took the watch and different adapters and wires and checked how much the ipad would charge. It tells what will happen if data + and data- are connected, hanging in the air, or a certain voltage. We just have a lot of different devices in our family, 6 iPads, 5 iPhones, 2 Androids, a couple of cameras, and they all charge in almost one place, so I want to have a lot of ports, and at the same time everything charges quickly.

Answer 4

To begin with, you need a power supply unit with a normal current strength (somewhere around 15-20A), then you connect devices to it in parallel.
