Question - usb power to bluetooth speaker and usb power output port

[Warren - Salzburg]

Hi community,

I am new here and this is my first post. I am new to electronics and come from a product design background, never electronic products though until now.

I would like to know:
If I have a USB cable (plugged into 240V AC) powering a bluetooth speaker (no internal battery) which also has a usb port to provide power to a secondary device (i.e. phone charger cable, etc) will there be sufficient power through one cable from the power source? surely I don't need two cables from the power source?

Please confirm your thoughts. All advice would be greatly appreciated.

Warren.
Salzburg.

Hi Warren
welcome to EP

If I have a USB cable (plugged into 240V AC) powering a bluetooth speaker

I assume you meant to include that there was a 240VAC to 5VDC plugpack in there somewhere ?
and that being the case, you need to look on the plugpack and see what the current rating is on the 5V output
