How to power the radio with a USB charger?

Question

Iron

There is a radio. Power supply from 3 fingers or from DC 5V.
There is a charger with a USB mother connector (not mini, not micro, regular).
There is a DC 5V dad from a Chinese universal adapter.
There is a male USB donor cord.
How to collect power for the radio receiver from all this and will it work?
Can you buy this from DNS?
How to search? I only find expensive adapters with a different DC 5V plug.

Answer 1

Any USB adapter is suitable for powering any radio with three AA / AAA elements, since even the weakest such adapters are capable of delivering a current of 300 mA (I have not met weaker ones), and the radio consumes current depending on the volume - which means that when listening to such a low volume the current is certainly enough (well, when the volume is increased due to a lack of current, distortion will occur - these are trifles).
You cut the USB cable, there is red - plus, black - minus, connect (preferably by soldering) according to the polarity on the radio power plug - and that's it.
By the way, if the adapter is of very low quality, it can interfere with radio reception - if this happens to you, then it's out of luck, change it to another one.
