Could you check what the max charing current on the OP7p is with Ampere or a similar app?

Scratch this one, after awhile it started to no longer plug in properly, I tried getting a new one and right off the bat it audio didnt work and about 2 days later the power plug no longer worked.

This is working fine for me although only up to 1200ma
1.2a @ what voltage?

Unfortunately one linked above I can not find in the US but I did find that UGREEN just released a model:
https://www.amazon.com/UGREEN-Supports-Headphone-Charging-Aluminum/dp/B07H76VRPZ/

UGREEN is the first "brand name" that I know of that has released an adapter with charging so this may be a great sign of things to come!

I don't know, i'm going off ampere app as I don't have hardware to get actual values
Strange the app would not tell you that because otherwise the app does nothing. Knowing the amps without the volts has no meaning. It is like asking how bright a star is and you tell me the temperature of the star instead and no information on the radius. lol

Now I could be wrong but maybe the Oneplus 7 only supports 5v charging in which case 1.2a is even slower than the minimum normal charging speed of 2a @ 5v.

For reference while the warp charger supports up to 30W it means that at 1.2a your charging at 6W or about 1/5 the maximum speed. (assuming 5v)

BTW this means that when looking at charging specs for batteries and other things to charge your 7 pro your going to want to look at the max amps supported @ 5v.

but it does not have charging function while headphones plugged in..
Buddy if you'll use a splitter ( which is not recommended)
You'll be compromising both audio quality and charging speeds.
I tried some of them. It's a waste of money.
What i rather do is charge my phone first coz it has 30w wrap charge which is very fast.
Then use the audio adopter to use headphones

Or a very simple solution buy galaxy buds. Better than airpods in every way and you can use you phone while charging while watching a long movie.

Profit ! ?
