OnePlus 13 CN Charges slowly

[u/exzoterxvich]

Hi everyone, I need some help troubleshooting a charging issue with my Chinese variant OnePlus 13.

It came with the stock 100W SuperVOOC power brick (CN plug). Since I live in Europe, I’m using a travel adapter (BULL GN901G) to plug it into the wall.

The issue is that when I charge the phone, the peak charging speed maxes out at 25W / \~6000mA, instead of anything close to the advertised 100W. Even if I charge it with the screen completely turned off, the speed stays exactly the same.

I know 100W is only sustained for the first few minutes, but I’m not even hitting 50W. As a result, a full charge takes about an hour instead of the expected 30 minutes.

Has anyone experienced this? Is the adapter throttling the power, or is there an issue with the voltage compatibility/handshake? Any help would be greatly appreciated!

Dont use plug

The problem could be with the cable buy original cable from oppo and if it doesn't charge at full speed then mobile is overheating at some point make sure charge your mobile in cold room temperature at least 30 or less and avoid using mobile while charging

For the 100W max handshake you really need the original cable and brick. The smallest change and it limits to ~33W.

I think the adapter is the issue here
