Overview

The 20W adapter is the plain, single-port option. Apple's user guide lists two USB Power Delivery output levels, 5V at 3A and 9V at 2.22A, which is the 9V profile most phones use for fast charging.

It isn't meant for laptops, and it charges one device at a time. If you only need to top up a phone overnight or at a desk, it is often all you need.

Best for: Charging one phone.

Evidence notes

Apple's US page gives a part number only. The output values come from the user guide group that includes model A2305; we couldn't confirm that model number for this exact part.
Only the UK English edition of the user guide was available.
We couldn't check the UL and Intertek certification databases automatically on 2026-10-24; a manual check is still to do.
No FCC ID is stated on Apple's pages we read.
Release month not recorded: no Apple press release or product page we read gives a date for this part number.
ChargerLAB teardowns exist for several revisions of Apple's 20W adapter, but none ties to part number MWVV3AM/A, so none is listed as a review.
No CPSC recall names this adapter (saferproducts.gov searched 2026-10-24).
