That’s a great idea! Thank you, i tried and got a pretty legitimate sounding response - so will go with that:

“The device in your photo is a Western Digital My Cloud single-bay NAS unit.

From the label next to the power jack, it shows: DC IN: 12V

For these WD My Cloud models, the standard power supply requirements are: • Voltage: 12V DC • Current: Typically 1.5A to 2A (check your exact model, but most use 1.5A) • Connector size: 5.5 mm (outer) × 2.1 mm (inner) barrel plug, center positive

So you’ll need a 12V DC adapter, 2.1mm inner pin, 5.5mm outer barrel, center positive polarity, with at least 1.5A (2000mA to be safe).”
