Idk. Like all the usb ports were capped at like 5v 1a with shorted data lines. I always used my own charger just because it would take 6 hours to charge my phone using the built in usb plug.
This is why next to my couches are multi-port chargers.
The ones I'm using currently have 8 ports; 2 at 65W, 3 at 30W, and 3 at 20W. The 30 & 60 are USB-C, 20W is USB A. The 65W is plenty for laptops, tablets, and phones. 30W for tablets and phones if the 65W is in use or headphones, eBook reader, etc. 20W for all that miscellaneous simple device charging, anything micro USB, etc.
Way better strategy than built in IMO. Easy to replace, old one goes somewhere else (or given to family members), etc.
