Super Stereo Ear MK136 Power

Hi,

I would like to be able to power my Super Stereo Ear with a 5V USB Powerbank battery system (Anker 20100).

I am not experienced in electronics, can you provide me with the basic detail to achieve this please?

I have tried to wire up a USB connection and plugged in to the mains via a USB plug, but I get a consistent hum/interference noise.

Thanks in advance for any information you can provide.

Regards

Darren

Hi

This is due to the the switch mode power supply inside your powerbank.
Due to the switching there’s “noise” on the power lines.
You’ll need to use battery
