A 2026 MacBook Air 15" is in transit. I am looking at docking stations to enhance my setup. Since my power adapter is a MagSafe should I power the laptop and docking station separate or can they be daisy chained?
Hi,
You can power your 15inch MacBook Air and connect a docking station at the same time by plugging the dock's USB-C/Thunderbolt cable into the laptop for data and displays, while leaving the independent Apple Support MagSafe 3 Cable plugged into the MagSafe port for power. Your Mac safely manages multiple power sources and draws from the one with higher wattage.
You should power your laptop and docking station separately. Most standard docking stations cannot pass enough power through a daisy chain to charge both the dock and a high-draw laptop safely. Always plug each device into its own wall adapter for stable performance.

That is good general guidance. However my experience has been that some docking stations can adequately power the laptop plus the dock itself along with other devices that are connected.
I obtained an OWC 14-port docking station back when I had a 2019 MacBook Pro 16" that had a 96W charger. It ran fine on the 85W provided by the dock, which also had multiple external drives it was powering, plus a monitor was connected. Then I started using that setup (85W from the dock pass through power) with a MacBook Pro M3 Max, which came with a 140W charger. That also worked fine.
I think the OP should be prepared to connect both the charger and the dock as suggested but should first try with just the dock providing pass through power. It might be plenty for how their MacBook Air may be used.
Charge your Mac laptop computer - Apple Support
"If your Mac has a MagSafe 3 port, it might also have USB-C ports. Your Mac charges over only one port at a time, using the source that provides the most power. Connecting a charging solution to more than one port, whether MagSafe or USB-C, doesn't charge your Mac faster."
