Buyers of the wall-mounted HomeView need to check one number before they order: the power adapter. Apple's support page says the wall model needs a USB-C adapter of at least 20W that supports 9V at 2.22A or higher, sold separately. Its own 40W adapter is a compatible option; prices are listed below.
What Apple says the wall model needs
9to5Mac reported the requirement on Oct. 13 at 5:29 p.m. ET, after Apple published the document. Apple's support page lists two different requirements:
- HomeView (Wall Mounted): per Apple's support page, a USB-C cable and USB-C adapter, both sold separately, of at least 20W supporting 9V at 2.22A or higher.
- HomeView (standard): at least 30W supporting 15V at 2A or higher. Apple says this model ships with its own cable and adapter.
What happens with the wrong adapter
Apple's support page says that if the requirements are not met, HomeView shows a "Not Enough Power" message and a lightning bolt with a yellow exclamation triangle. Apple does not say whether the display still runs, at what level, or only shows the warning. 9to5Mac's headline says it "may not work"; that is its wording, not Apple's.
Which adapter, and what it costs
Apple's 40W Dynamic Power Adapter with 60W Max is described as "also a compatible power solution for Apple HomeView." The adapter comes alone, and Apple lists its own charging cable as sold separately.
The USB-C Wall Connector mount, per Apple's mount page, comes with an attached USB-C cable and needs a power adapter of at least 20W, sold separately.
The USB-C mount setup costs:
- HomeView (Wall Mounted) display: $299
- USB-C Wall Connector mount: $59.95
- Apple 40W adapter: $39
- Total: $397.95 before tax
Apple's wall-mounted HomeView page also lists two hardwired mounts. Apple's support page says a hardwired mount connects to line power instead of a separate adapter:
- Power Mount AC Wired: $79.95
- Power Mount PoE Wired: $129.95 (Apple's page shows "Check back later for availability" on this mount only)
Who is affected
Only wall-model buyers who use a power adapter. Apple's support page says that depending on the mount you can use a separate cable and adapter or connect to line power (hardwired). Apple's wall-mounted HomeView page describes the AC Wired and PoE Wired mounts as hardwired.
Why it matters
A "20W" label is not enough on Apple's wording: the adapter must also support 9V at 2.22A. Our untested assessment: check the charger's supported output profiles before relying on its wattage label. The total above is higher than our earlier cost breakdown because that figure excluded an adapter.

What we would buy
This is our read, and we have not tested HomeView or any adapter. If you are using the USB-C mount, buying Apple's adapter is the choice Apple itself names. If you already own a charger, check its label for 9V at 2.22A before relying on it. If you chose a hardwired mount, ask your installer which power it uses.
