Step 1: Your Devices

How will you charge them?
Recommended Size65W GaN

A 65W GaN Charger is the ideal fit for your setup.

A 65W multi-port charger is the universal sweet spot for everyday travel and desk use. It can power your laptop at full speed on its own, and automatically drops to 45W when you plug your phone in—keeping your laptop battery steady while your phone fast-charges.

How power splits when devices are plugged in:

When both are plugged in: Port 1 gives 45W to your laptop, Port 2 gives 20W to your phone.

Cable note: Important: Standard USB-C charging cables are limited to 60W. To deliver full power from a 65W, 100W, or 140W charger, make sure your USB-C cable is rated for 100W or 240W (E-Marker certified).
Canadian safety tip: Always verify that any wall charger plugged into a Canadian outlet has a physical CSA, cUL, or cETL mark stamped into its plastic casing.
