100W GaN Wall Charger

The Corn Electronics wall charger delivers up to 100W of power through four ports using gallium-nitride technology. It combines three USB-C outputs and one USB-A output in a compact black housing with a retractable plug. The adapter supports multiple fast-charging protocols for laptops, tablets and phones. A single USB-C port can provide the full 100W when used alone.

Travellers needing one charger for many devices

This unit suits users who want to charge a laptop, phone, tablet and accessories simultaneously from a single wall outlet. The foldable plug and palm-sized footprint make it practical for carry-on luggage. Buyers who need more than four ports or require a cable in the box should look elsewhere. The package contains only the charger itself.

100W single-port maximum

When a single device is connected to one USB-C port the charger can supply up to 100W, enough to bring an M2 MacBook Air to 55 percent in under 30 minutes. With multiple devices attached the total 100W budget is shared across the active ports. Choose this adapter only if your most power-hungry device can accept 100W over USB-C.

Questions about this item

Which USB-C cables do I need to get 100W from a single port?

Use a USB-C cable rated for 100W Power Delivery; the charger supplies up to 100W on one USB-C port when used alone.

Will my older USB-A phone still charge at a reasonable speed when plugged in with newer USB-C devices?

The USB-A port delivers 5V at 2.4A, so legacy phones charge at their standard rate while the USB-C ports share the remaining power budget.

How can I confirm the charger is delivering the expected 100W to my MacBook?

The MacBook battery indicator should show roughly 55% charge after 30 minutes when connected to a single USB-C port, matching the rated single-port output.
