The Afterplug Dual USB-C Extender solves a specific MacBook annoyance: hard-shell cases that block your ports just enough to make hubs and cables sit crooked or refuse to seat at all. This aluminum pass-through adapter mounts over your MacBook's built-in USB-C ports and gives you two accessible ports on the outside of the case, so you can connect a hub, a display, and a charger without stripping the case off first. Because it is a pass-through rather than a powered hub, it carries your MacBook's native signal straight through: up to 240W Power Delivery for charging, 8K video output, and…

Frequently Asked Questions

Will this work if I keep my MacBook case on?

Yes - that is the point of the design. It seats into your MacBook's USB-C ports and extends past the case edge, so hubs and cables that would otherwise be blocked by a hard-shell case can connect normally.

Does it slow down my transfer or charging speeds?

No. It is a passive pass-through, so it carries the port's native performance: up to 240W Power Delivery, 8K video output, and 80Gbps data on Thunderbolt 5/4/3 and USB4. The exception is the MacBook Neo, where the machine's own USB 3 and USB 2 ports set the ceiling.

Which MacBooks is this compatible with?

Afterplug lists MacBook Pro 2016 and newer and MacBook Air 2018 and newer. Confirm your exact model year on the product listing before ordering, since port spacing differs across generations.

How does it protect my MacBook's USB-C ports?

It stays seated and absorbs the repeated insertion and removal cycles that normally wear out the port contacts. You swap cables in and out of the aluminum extender instead of the soldered ports on the logic board.

Is this a USB-C hub with extra ports?

No. It is a 2-port extender, not a hub - it relocates your two existing USB-C ports outward and does not add HDMI, USB-A, or card slots. You can plug a hub into it if you need those.
