they forgot a battery .

I did really like this radio it was heavy well built well put together but they made it look like it's portable? it is if you carry a generator and an extension cord with you then you can take it wherever you want that's the reason I took it back to the store. that was the one deal killer for me. now I've got to go back and try to find another one that has everything including a battery that will play when I'm out somewhere without a generator.

Don’t buy!!!!!

Sounds like the music in my car, I wish the volume was more plus it’s extremely heavy. I don’t recommend I should have spent another $300 for the jbl 720 but will return.
