I've been lurking on the forums looking for workarounds for getting a powerbank to remain switched on when it's attached to a 9v guitar amp via a 3v/5v-to-9v step up usb cable. Sorry for interloping in your Arduino business!
CURRENT SET UP: Powerbank>>>3v/5v-to-9v USB>>>Guitar Amp (switches on only when guitar jack is inserted)
My Anker Powercore 10000 switches off after ~1m30s and Anker customers service say it will do that if consumption drops below 50ma. This is the proposed work-around I wanted to get your advice on.
In order to stop the Powercore switching off, to give it something about 50ma to power, I'm proposing opening up a male-to-female usb power cable and a small LED reading light like this...
...and soldering the light in at a point along the cable, like this...
M
A---------- (+) FEMALE
L---------- (-)
E
LED LAMP
M ||
A-----||----(+) FEMALE
L-----------(-)
E
...and then plugging it into the 3v/5v-to-9v USB. So...
NEW SET UP: Powerbank>>>Adapted male-to-female USB cable>>>3v/5v-to-9v USB>>>Guitar Amp (switches on only when guitar jack is inserted)
I'm hoping I'll be able to plug my guitar into the amp (creating a circuit) and switch on the powerbank, which will power the amp and stay awake thanks to the lamp but when I remove the jack from the amp the circuit will be broken, the lamp will go out and the powerbank will go to sleep. Do you think that would work?

Hi, I am using a PowerAdd Pilot X7 and found that if I turn on the torch the power stays on indefinately, even after the torch has been turned off again. Just hoping this may help someone
Really? Wow, that might be the answer I'm looking for.
