MacBook charging extremely slowly, after using 3rd party USB-C charger

Spread the love

I have a 16″ 2019 MacBook Pro.

A few days ago, I didn’t have my MacBook charger on hand. After a quick internet research of whether or not it works, I borrowed my wife’s DELL XPS charger (USB-C, 130W I believe). My MacBook charged fine with it.

A few days later, I noticed that my MacBook is charging very slowly (with my Apple 96W charger). I reset the SMC, rebooted, tried a different wall outlet, installed all system upgrades. No luck. Charge speed is around 1% point every 20 minutes with all apps closed. When I run a computing intense task (having a lot of Google Chrome tabs open, or compiling code), the battery discharges.

I checked the battery status with coconutBattery, but things seem to look normal. The only thing that seems off is that charging wattage. I’d expect that to be somewhat close to my 96 watt maximum.

See the attached screen shot. Note that this is with all apps closed.

Are my issues due to my charger experiment a few days ago? Is this just coincidence and my Apple charger went bad?
