Frequently Asked Questions
Will this adapter run two external monitors on my M1 or M2 MacBook Air?

How much power does it pass through to charge my MacBook?
The USB-C Power Delivery port passes through up to 60W. On the 16-inch MacBook Pro with M1 Pro/Max, the MagSafe 3 port charges at up to 140W, so plug your charger in there for faster charging.
Does it work with Thunderbolt or DVI displays?
