    The A2119 adapter will pass through up to 84 watts. Source: me, I have it and tested it on a 2019 MBP 15".

  • I’m getting only 55 watts. I noticed this when my MacBook Pro 15 2018 starts to drain the battery being connected to the original charger throuh the adapter. I looked in the iStat app the power source abd it shows 55W. Connected directly shows the full 86W and never drains the battery.

  • No, it does not.

    it will take longer to charge using this adapter than it would charging directly from the standard charger. About 30-40% longer in my experience.

    This won't be an issue for everyone, but if you need to frequently top-up between meetings, for example, you may find it can't keep up (for this reason, I often have to fall back to the standard charger).

  • Reviews online state that the previous version of this adapter, and most other adapters on the market, are limited to 60W only. There is no reason to expect this to do 87, as Apple probably would have advertised if it could.
