So one of the things I wonder here is, if I plug all 4 ports into chargers, will it charge faster? I know the onboard battery is current limited, but I wonder how it works in practice.
- randall 10y agoInteresting! I hadn't even considered this.
- SiVal 10y agoSince there will be many occasions where power is being passed in on more than one of the USB-C connectors, the new Macs are designed to take power from the ONE charger that offers the highest power (capped at some limit) and reject power from all others. So, plugging in all four will NOT charge faster than plugging in just the one offering the highest power. This is a very explicit, intentional design decision, not some hidden side effect of something else.
- jaggederest 10y agoThat also makes me wonder whether devices that both charge and provide power get confused. Is there a hierarchy of charging beyond simple amperes provided? Otherwise I could see plugging in a spec-max 100w portable battery and draining it prior to pulling from the wall charger.
