Since I do not want to highjack Kazenorin’s Post I am starting a new one here:
I read in many posts, that other chargers than the V original charger can harm the V (mostly by over-current).
I am only talking about all the 5V technologies with the weirdest Ampere ratings. E.G. 5V@5A
That excludes Qualcom Quickcharge and other special technologies which increase the Voltage above 5V.
I also read that, the V charger can harm other devices (like phones) because of the over-voltage.
Here I am talking specifically about USB-PD
I read some explanations in the Internet about the used charging technologies and they state that this is not true, if the chargers are not defective (=working like specified).
Here is my summary, Sources with Quotes and Links following:
Harming the V:
"Intelligent" (e.g. Anker PowerIQ) and also "dumb-non-standard" (e.g. Samsung chargers which only support one charging protocol) chargers cannot force current into the device since they are Voltage Sources and the Current is determined by the internal resistance of the device.
As long as the charger does not increase the Voltage higher than USB standard and the device does not "ask" for more current (decreasing its own resistance after recieving a modifiing data Voltage from the charger ) the charger delivers exactly the current that the device wants to have.
Therefore (Not speaking about Qualcom Quickcharge and USB-PD which increase the Voltage) the anker PowerIQ and other Power adapters cannot harm the V by offering more current, sice they simply cannot force the current to flow through the device.
Qualcom Quickcharge (The only thing harmful for the V if the above is correct) would be Indicated like this on Anker products: https://www.anker.com/products/A2024111
But since the V is capable of USB-PD it should also be able to handle higher voltages .
That means the PowerIQ from Anker should not harm the V.
Harming other Devices with V's USB-PD Power supply:
This simply is not possible either, because the USB-PD protocol starts at 5V@2A  and only increases voltage if the device demands this (different technology than the old "intelligent" chargers!).
That means, if my phone does not ask for more than 5V it does not get more.
I know that giving warranty on something is another case here and I understand that EVE says that if you use another charger you can harm your device and it is not their fault. But it should be very unlikely.
I hope @Team can solve this confusion.

I have got an earlier version of this Charger at home with ~6 USB-A Ports and an 26Ah Battery-Pack from Anker with the same technology. I would also appreciate it to charge my phone (currently Nexus 6P) with the V charger (eliminating one charger out of my backpack).
