Learn the right order to plug in your laptop, phone, and cable on the Anker Prime Charger 100W GaN so you get the fastest charge and avoid port conflicts.

Quick answer

Plug the included 240W USB-C cable into the Prime Charger's top port first, connect your laptop, then add your phone to a remaining port. This order prioritizes the device that needs the most power and helps you avoid renegotiating power when a second device is added.

Why port order matters on a 3-port GaN charger

The Prime Charger (100W, 3 Ports, GaN) shares its total output across connected devices. When you plug in a laptop first, the charger allocates high power to that port; adding a phone afterward triggers a renegotiation that can briefly pause charging on the laptop. Starting with the highest-draw device reduces those interruptions.

The included USB-C to USB-C cable is rated for 240W and 6 ft, so it can carry the full 100W the charger offers without becoming the bottleneck. Using a lower-rated cable on the laptop port may cap charging speed even if the charger has headroom.

When you should plug in the phone first

If your laptop is already mostly charged and your phone is nearly empty, plug the phone in first. The charger will give the phone a fast top-up, and you can move the laptop to another port afterward. The trade-off is that the laptop may charge more slowly until the phone reaches a higher battery level.

There is no dedicated “phone port” on this charger; all three ports are USB-C, so the order you choose is about priority, not port capability.

Step-by-step: plugging in your devices

Connect the 240W cable to the charger first: Plug the USB-C to USB-C cable into any port on the Prime Charger before connecting your laptop. Common mistake: connecting the cable to the laptop first can cause a brief power negotiation delay when the charger is already live. Always attach the cable to the charger before the device.
Plug the laptop into the cable: Connect the other end of the 240W cable to your laptop's USB-C charging port. The charger will deliver the highest available wattage to that port. Checkpoint: confirm your laptop shows it is charging; if not, try a different port on the charger. Verify charging status before adding more devices.
Add your phone to a remaining port: Use a second USB-C cable (not included) to connect your phone to one of the two free ports. The charger will redistribute power, so the laptop may charge slightly slower. Common mistake: using a low-power cable for the phone can slow its charge unnecessarily. Use a cable rated for at least the phone's fast-charge wattage.
Leave the third port free or add a third device: If you connect a third device, expect the total 100W to be shared among all three. The charger does not have a dedicated high-power port, so plan which device needs the most power and plug it in first. Checkpoint: if a device stops charging, unplug another device to free up power. Prioritize devices by battery level and charging speed needs.
