I had a similar issue. If you don't keep the battery charged it will go flat and the only way to recover is to perform a reset with the power supply connected and give it a full charge. Make sure you have the original charger as well. I found instructions on the B&O web site on how to revive the battery after running it flat.
Unfortunately, this is not possible without further ado. With DC-IN, the unit expects 15V. A power bank only provides 5V. You could connect a boost converter in between. However, this requires knowledge of electronics and can damage the unit if used incorrectly!
Excellent compatibility, great product
