as I bought a battery-powered speaker lately, I was wondering if e.g. a MOD Duo X can operate on the battery of an Unbreakable Power Supply for mobile performance.
The power supply consumes 12 Volts at 2 Ampere that comes to a total of 24 Watts (P=V*I). So it could run for 50 Minutes on an UPS like FPS Nano 600, which has a Backup Time of 10 Minutes for a 120 Watts device, right?
Does somebody know other UPSes available in Europe with a small form factor but more Backup Time?
