    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.

    Hi Warren
    welcome to EP :)

    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
