D6000 Mac Book Pro Compatibility

It’s my understanding that the MBP will select one “charging” source so you don’t have any safety concerns.

I’m not sure how it goes about “choosing” but I suspect it would prioritizes it’s high-output Apple power supply over the power avail from the Dell dock.

That said, 65W is a LOT of power.

For comparison, I routinely operate my own 16” MBP on an 18W Apple charger. (Not a typo … eighteen)

The battery SoC slowly climbs in low-demand periods, and slowly drops in high demand periods.

FYI, the actual charger is INSIDE your Mac.

What we commonly call a “charger” is really a DC power supply. They are fairly smart devices today and “negotiate” a voltage to best meet the needs power needs demanded by the laptop - as possibly limited by the interconnecting cable.

After reviewing the Dell’s specs, while it WILL work, it will not support the full capability of the ports on your MBP.

If the higher USB 3.2 speeds or Thunderbolt capabilities aren’t a need in your application, you should be in good shape.

The actual power delivered is a negotiation between the source, the computer and the connecting cable.

While 65w clearly can’t restore a deeply discharged laptop as quickly, adherence to the USB-PD spec by all players ensures that all works well together.

Tip: Don’t skimp on the interconnecting cable.
