Geeinget for the Raspberry Pi, but still trouble with automatic shutdown.

I bought this Power Bank to power a Raspberry Pi USB and a Class D amplifier via 12V power. Since the Raspberry consumes little power, there are other Power Banks often the problem is that this off Due to the low power consumption the current output after a few seconds. The problem does not arise in combination with the P and I can operate the Pi well over 10 hours. At even lower consumers results but unfortunately the problem with the low power consumption. When I connect a Class D headphone amplifier at the 12V output, I can use this only when I connect an additional consumer to a 5V output, otherwise switch off the 12V output. Apart from the 12V output is practical and works simultaneously with the 5V. It is thus possible, with the Raspberry Pi, a Class-D amplifier and normal shelf speakers (eg: JBL Control 1G) to allow for 10 hours on low volume music in stereo quality through this Power Bank mobile. (With regard to my neighbors I use time at full volume is not determined)

A disadvantage of the device is still that it requires its own power supply for charging. The USB charging cable is standard and very convenient for cheaper Power Banks, as you normally carries around already enough power supplies themselves.
