My phone came with a USB C to USB A OTG adapter, can this adapter handle the power if I used it in a USB PD port and charged a larger USB device? I think it's intended for flash drives and external hard drives, but it works for charging so far. Note: for the charging device, it pulls around 3A @5v....

 

USB-PD is a USB-C feature. USB-A was not designed for 2.1A, but you can find quite a few aftermarket and even some motherboards that support >500ma @ 5V. USB-PD supports around 100w @ 19.5V 

 

The adapter is probably intended for the data transfer, not charging, but phones can usually still charge from a USB-A port, they just charge very slowly.

USB A is not rated for That much current, 2.0 only does 500mA.

You need a USB C connection for the device to accept higher voltages and currents available through PD.
