Using Xiaomi MDY-08-EH Charger for Multiple Devices: Kindle, Samsung, HTC and Teclast

Hello,

I have a few questions for you - I would like to check how you are dealing with charging your devices with different inputs?

Some time ago I bought a Xiaomi Mi5 s phone, which is the first usb c device I have.
Until now, I had everything on micro usb and still used several chargers - stronger for the Teclast X98 tablet, weaker for HTC / Samsung / Kindle ebook. I read a bit about chargers, usb c standard (and I know that it is not worth using no-name cables and adapters) and the charger attached to mi5 s - MDY-08-eh and I decided to eliminate several chargers and replace them with one - the question is whether I will not burn anything Here are some related questions - I hope someone will help me and answer them.

1) Because the Xiaomi MDY-08-EH charger has (apparently ) QC 3.0 (Quick Charge 3.0) I wonder if it can land Amazon Kindle devices, tablet or Samsung Galaxy ace 4? If these devices are not compatible with QC 3.0, I understand that the charger / device will choose the charging current themselves? Because standard chargers, even if they are more powerful, choose the values for the device (in fact, the device selects the maximum values it can take from the charger), so probably the chargers with QC 3.0 also work this way?

2) To eliminate the various ends of chargers (1 at home, 2 at work) I plan to connect the micro-usb cable (instead of the original usb-c) to the MDY-08-eh charger and to the tablet's USB-c adapter ( some company, e.g. Unitek). Such a solution carries some dangers? Because it seems to me that everything should work and depending on my needs I will be able to charge via micro-usb or usb c.

3) I will check the data of the chargers that I want to use. They have the following parameters - probably their parameters are ok, and they can be used interchangeably to charge the above mentioned devices?

MDY-08-EH - original from Mi 5 s

AC input: 100-240 VAC, 50-60 Hz; 0.5 A

DC output: 5V-2.5A; 9V-2A; 12V 1.5A

TP-u25 - from the Teclast X98 tablet

AC input: 100-240 V; 50/60 Hz; 0.3 A

DC output: 5V-2.5 A

Charging the phone with the original 0.85A charger = 400mAh power consumption.
Charging the phone with a 2A charger from the tablet = 600mAh power consumption. and faster charging.

This is how it looks with me.

Charging power banks similarly, only with smaller differences.

@ WędkarzStoLica - thanks for the feedback.
I wonder if Quick Charge chargers can be safely used in the above way?
I think so - since the systems controlling the consumption are in the devices, but I wonder if anyone can confirm these guesses? I tried to find something on this subject and only throws results on the subject of "reducing battery life" by QC chargers. There is no word about their use in devices without QC function.

You know I have your One Plus yours and on the original charger if it is hungry it takes 2A. On others, depending on the power, he takes the back what he needs. On 1A it takes 1A on 1.5A it takes 1.5A and on another 2A it also takes almost 2A. I just have a 5V / 6.5A power supply from some router and all cables soldered. All phones and tablets land on it. Somehow it works. One Plus take 2A remaining max 1A old HTC only 0.6A
I also have a long 3m cable but it is thin and max what I squeeze from it is 0.5A.

And do you think that with quick-charging chargers in the Quick Charge 3.0 technology will be the same?
Because I'm mainly worried about them.

It is true that I just found such a test:

http://onetech.pl/ladowarka-blitzwolf-bw-5s-z-quick-charge-3-0-test-i-recenzja/
which shows that the iPhone 5s was charged and worked, so there is nothing to worry about.

But I was hoping that maybe someone would share their own experience about the QC charger.
But thanks to you you have calmed me down a lot about "traditional" chargers, but with more intensity than the original ones

Cables and connectors are standard so no more electricity can be squeezed. Therefore, the QC standard increases the voltage, which gives more power at a lower current. The whole philosophy.
The battery itself will receive more power than it can. So the differences in full charge between a regular charger and QC are not large. Instead, they show up when connecting a discharged phone for those 10 or 15 minutes. Or during the charging of a deeply discharged battery and intensive use. Thanks to QC you use a phone and the battery charges very quickly because the connection cable can send more power.
Although most chargers at higher voltage have less press capacity, so much more power does not go. These 2A at 5V are 10W and 1A at 12V is 12W so only 2W more.
See this charger.

Gives at 5V 2.4A at 9V 2A and at 12V 1.5A
So from 12 to 18W

Thanks - on another forum I also got answers and I have a full set
