For a project i am working on i am looking for a way to build a device that will sit between a hub and a device and spoof the amperage of a wall charger.
Basically a problem that i have been having is I have a usb powered battery charger that is supposed to be able to operate at 2 amps but when plugging it into any sort of usb hub it will only draw 500mah even on a dedicated charging port and even when using a 4 plug power cable which should allow the max amperage from multiple ports on the hub resulting in a total of 2 amps.
I want to set up a breadboard project that basically connects to a usb hub via the multi ended power cable and spoofs the amperage of a dedicated wall charger to the connected device taking the negotiation of max amperage with the hub away from the device and giving it to the user as a manual setting. This would also allow me to trick the device into being able to use 2amp charging ports that it currently cannot negotiate with properly.
I know its kinda impractically but basically this is me just being bored and wanting to play around with a soldering iron for a bit to see if its possible
