Please recommend a power adapter for this device

Swift66

Hello,

I recently bought this bluetooth amplifier:

https://www.amazon.co.uk/gp/product/B01LFHO7UA/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1

and this power adapter:

https://www.amazon.co.uk/gp/product/B0083S19YW/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1


The adapter makes a continuous low volume, high-pitched noise which is very irritating.

Can anyone recommend another, perhaps non adjustable, basic adapter for this ? What specs / volt etc. should I be looking for? A link to one on amazon or similar would be appreciated.

Cheers

The power adapter is grossly under rated for this amplifier. The amplifier is "rated" at 100 watts which at 24V would need about 4 to 5 amps. Granted the amplifier's spec is a little ambitious but the power adapter you have chosen to run it is only capable of 12 (v) x 1.2 (A) 14 Watts - quite a bit short of what's required.

This high load may be causing the PSU to make the noise or the PSU is just a poor quality unit ?! I can't recommend a PSU but choose something with a bit more current capability. Something like 15 - 19 Volts at 3 amps should do - I don't believe for a second that the amplifier is capable of 100 Watts but if it can deliver even half that - 50 watts - then a PSU with that rating should be usable. I can't imagine a PSU with 24 Volts at 5 Amps would be too portable
