SO after trying about $100 worth of c bunch of cables inlcuding one from ebay someone linked (which doesn't charge the phone but is extremely unreliable, dropping the connection almost every 5 minutes), and
Cable Matters as well as
Meenove Store (from amazon, someone suggested this as well), those two charge the Oppo. Not to mention about 10 other different variations of cables (most of which, i think, are constructed for people who want to connect their micro USB stuff to a macbook or something).
So far the ONLY thing that works are:
- Use the provided OTG cable (the one the oppo comes with) and get a USB C to micro USB OTG Adapter note: this must be an OTG adapter, there are some "usb c to micro usb adapters" that meant and built purely to be able to use your micro usb charging cable with your usb c phone, those WILL NOT WORK as the phone will not detect a peripheral e.g. of what worked for me: https://www.amazon.ca/gp/product/B01GESWAJU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1. Plug one into the other. This is still not TOO Reliable especially if you're running around with it in your pocket it does seem to disconnect sometimes, but you can try to get a better OTG adapter that's built better.
- The following stupidity will 100% work, and you're likely to find each section/cable more easily: Micro USB OTG adapter (for older android phones, ends in female USB), USB C OTG (note, this must be OTG, ending in female USB), and USB male to USB male transfer cable. Chain these 3 things together and viola!
- The above should give you a clue, something many people have mentioned on this thread, as to what should ACTUALLY be done: micro USB OTG cables short the "charging wire" for micro USB (which is why a lot of "usb to micro usb" don't work, as they wont bother shorting out the charging pins on the micro USB side, those are meant to use micro usb with usb c macbooks so they are MEANT to charge the micro usb peripheral), so even though the rest of the wire may allow pulling a charge the oppo never does as that specific pin is shorted. The usb C to USB A must be OTG cable (this is why adapters that are meant to just charge USB C phone with micro USB cables will not work), there are certain things about how these are constructed that lets my phone see a USB peripheral properly. With these two ends of the connection done up in that exact way things should work. the phone will still think it is supposed to be charging the Oppo but it never does since on the oppo's side the charging pins are shorted. Thus no electricity changes hands.
