Hello everyone. I made a solar usb charger that, by having three 6W panels + 5V dc-dc converters in parallel, must be capable of providing 2 to 3 amps in full sun. I have connected a female usb connecter to the panel outputs and shorted the data pins as I read somewhere else that that tells a device it is a dedicated charger and can provide up to 1.5A.
Now when I connect a powerbank or phone to it via a usb current and voltage meter, it says to only charge the device with 500 to 800 mA. I know the panels have more power to provide because when one panel is blocked by hand, the current is maintained on the usb port.
I read having 2V on the data pins might help, but I also read that that might only help with charging apple phones. Furthermore adding an additional usb port and charging 2 devices at the same time might double the power generation but it is not ideal ofcourse.
So my question is, what do you people suggest to do in order to utilize the maximum amount of power from the solar charger? Thanks!!
