Headphoneus Supremus
Got a 13000mAh battery pack, so have never really tested it.
On extending playing time, depends on your cable.
Ordinary Y cable draws power from both sources. So even with a battery pack, your DAC/Amp still draws power from your Source.
So what I did I have a standard Y cable with one connecter covered its 5V pin (see red vinyl tape).
And hook up a Delock 65296 adapter to Source (Smatrphone/Tablet)
