yaesu vx 150
Yaesu Battery Charger NC-72B getting hot?

The adapter is getting really hot. The input 120V 60Hz 12W – output 12V DC 500mA is the adapter brand. My radio is a Vertex VX-150.
Is there a defect?

where in the world are you?
if in the UK, its a wonder the thing hasn’t blown up!
if in the USA – look on the back of the radio you are powering from the adapter and look at it’s power consumption it will say something like ” input 12VDC 900mW” or 750VA or 0.5A or 500mA this Will tell you if you are over running the adapter another test would be to leave the adapter plugged in WITHOUT plugging it into the radio –

In general, adapters tend to run warm but should not run hot
