Power geanu what I need

This is my fourth dual power supply (various products). One could not use it because it beeps constantly extremely noisy at night and I am charging my phone and my bed Kindle. The second was, although Samsung Galaxy stood in the description, my Galaxy S3 not load mini with one of the ports.
My previous favorite was the Inateck "20W 5V 1.5A / 2.4A 2-Port", it works with all of my devices and cables, and you hear nothing, neither with nor without cables or a connected device.
The "Industry Standard Double (Twin) -USB power adapter 5V / 2.5A" also invites all my devices (3 different Galaxy, Kindle, Raspberry PI) with different cables on both ports. Moreover, nothing to hear and it is significantly smaller than the Inatek, so more suitable for travel.
However, I can say something to the charging current, because I have not measured this neither to Inatek still on this device.
Both devices are very robust and I can wholeheartedly recommend.
