USB-C is a shape, not a promise. The same connector can trickle-charge earbuds or feed a 100 W laptop — depending on the charger's brain, the cable's wiring, and what the device negotiates. Canadians buying \"65 W GaN\" cubes at Best Buy need a short literacy course more than another mystery multipack from a marketplace seller.
Power Delivery is the common language
USB Power Delivery (PD) lets devices request voltage/current pairs. Phones often want 20–30 W class profiles; many ultrabooks want 45–100 W. A PD charger lists its maximum and sometimes per-port budgets when multiple devices plug in at once.
Proprietary fast-charge schemes still exist. Many modern phones accept PD PPS or similar; older cables and bargain bricks may fall back to slow 5 W behaviour. When in doubt, use the OEM cable for the first test, then swap.
Wattage cheat sheet
Typical useful charger class
Gaming laptops may still want proprietary barrels even if they accept USB-C for light charging. Read the manufacturer's wattage floor — underpowered PD can charge slowly while you work or not at all under load.
Cables are part of the standard
Not every USB-C cable is 100 W capable. Look for e-marker chips on high-power cables, and prefer reputable brands sold through Canadian retailers with clear return policies. Frayed cables are a fire and data risk — retire them.
USB4 / Thunderbolt cables can carry video and high power; they cost more. You do not need Thunderbolt pricing for phone-only charge cords.
Multi-port math
A \"100 W\" dual-port charger might offer 100 W on one port or 45+45 when both are used. Labels on Anker, Ugreen, Apple, Samsung, and similar lines usually show shared budgets — read them before you assume two laptops will both get full speed.
Safety and travel in Canada
- Buy certified chargers (cUL/UL marks matter more than glowing Amazon reviews).
- GaN bricks run cooler and smaller — still give them airflow in a bag.
- Air travel: power banks in carry-on; check Wh ratings on the case.
- Hotels with worn outlets: a quality surge-protecting strip can be kinder than forcing a wobbly wall wart.
One-bag recommendation pattern
Most travellers do well with a 65 W dual-port GaN brick, one 100 W-rated USB-C cable, and one shorter cable for the phone. Add a MagSafe or watch puck only if you use those devices daily. Leave the junk drawer five-packs at home.
Standards exist so you can own fewer bricks. Learn wattage and cable ratings once, then ignore the panic marketing every September.
