Overview

Apple's 140W adapter has one USB-C port. Its user guide lists output levels up to 28V at 5A, which is above the 20V maximum of standard USB Power Delivery and is what makes 140W possible.

It is overkill for phones and most laptops, but it's the type of charger needed to reach 140W on laptops that support it. Reaching 140W also requires a USB-C cable rated for 240W.

Best for: Laptops that support 140W USB-C charging.

Editor's notes

  • High-power laptops: the 28V level is needed for 140W.
  • Other laptops and phones: works, but most won't draw anywhere near 140W.
  • Multiple devices: not suitable; one port only.

Based on published specifications and typical power needs for each device type, one device at a time. It isn't a guarantee for a specific model, so check your device's own charging specs.

Evidence notes

  • Apple doesn't name a USB PD revision. We haven't inferred PD 3.1 from the 28V output level.
  • Only the UK English edition of the user guide was available; the US English edition returned an error.
  • 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 product page or support pages we read; the FCC equipment authorization search could not be queried by model name.
  • Release month not recorded: Apple's October 18, 2021 MacBook Pro press release doesn't name the 140W adapter, and no Apple page we read states a date for this part number.
  • ChargerLAB's 2021 teardown of Apple's 140W charger doesn't state a model number, and Apple has since released a newer A3607 revision, so we can't tie it to this part number and don't list it as a review.
  • No CPSC recall names this adapter (saferproducts.gov searched 2026-10-24).
