The RAVPower is not usable for me and the planned use (bedroom), there (about 100mA) quitscht under low load chrecklich. Add to this that the LED is too bright.
I then bought a 3.1A power supply of Twin FONTASTIC. This is extremely quiet, both under partial and full load. In addition, it is significantly smaller, the price comparable, chic, the LED very discreet (especially at night) and also the cable management is much more practical than the RAVPower (cable plugged from below, they are therefore not folded).
