Can this radio be bluetoothed to a bluetooth speaker

No, it can't work like that. It just works as a radio or as a bluetooth speaker.

The product information uses sd & micro sd interchangeably! It's a micro sd card slot not sd right? Can I connect via usb to copy files to micro SD?

It is a microSD slot. I don't know the answer to the 2nd part of your question - I copy my files through a card reader on my pc.

Can i charge my phone through the usb on the side of this radio??

Not really. the USB is a charging port for the radio itself.

how many watts does this radio have

I don't know the precise answer - it doesn't say on the packaging - but it produces a full sound with decent bass comparable to similar sized Bluetooth speakers costing considerably more. It is comfortably loud enough for listening to music in a kitchen or bedroom but obviously not capable of club or party volumes.
