Questions about this item

How much heat and noise does the 20 V adapter produce when it powers the Boombox continuously?

The adapter runs silently with no fan; its over-current, over-voltage and short-circuit protections keep temperatures low during all-day use.

What must I already own for this adapter to charge my speaker?

You need a JBL Boombox model MAIN-40911, JBLBOOMBOXSQUADAM, JBLBOOMBOXGRNAM, JBLBOOMBOXBLKEU or JBLBOOMBOXBLKJN and a standard wall socket.

Will the 10 ft cord reach the mains if my Boombox sits on the far side of the room?

Yes, the total 10 ft power cord gives plenty of reach from a distant socket to the speaker.
