Honestly that really sounds odd to me. I have bought a lot of electronics in the past which cost less than scanner radios and have also spent more and I have always had either a power cord/USB charger and batteries included.
So the math just isn't adding up right to me. Help me to understand your point
It doesn't really matter that it doesn't add up to you, or anyone else. A charger is not included, it was never stated that one would be included, thus it's no surprise that one isn't in the box. Get on with life, there are far more important things to worry about.
