Speed
Wired wins, and it is not close at the top end. A wired PD connection delivers 25-100W directly with the device's negotiated profile; a wireless station in the class documented here delivers up to 15W to the phone position with coupling losses on the way. For a depleted phone before a flight, wired is the answer. For the overnight and desk-top-up patterns that dominate real usage, 15W wireless fills the phone without the user noticing the difference. Sell speed wired; sell habit wireless.
Heat and battery care
Coupling losses become heat in and around the phone, and heat is the variable batteries like least. Magnetic alignment reduces the loss (better coupling), and phones taper wireless power as they warm - the mechanisms behind the heat discussion on the blog. Wired charging at moderate wattages runs cooler; wired at maximum wattage generates its own heat in the handset. For overnight charging, a lower-power wireless pad is a defensible battery-care choice, not a compromise.
Convenience and wear
Wireless removes the two daily frictions: finding the cable and aligning a connector in the dark, plus the mechanical wear that kills cables and ports. Multi-device stations extend the win: the 3-in-1 format replaces three chargers and three cables with one object. The counterweight is travel bulk and the fixed position - a wired charger works in a car, a train and a cafe with equal ease, and the retractable-cable format closes most of the tidiness gap.
Merchandising both
Programs that carry both formats sell each on its true strength: wired GaN for speed tiers (wattage ladder), wireless stations for desk, bedside and gift sets. The shared specification language - inputs, ceilings, tapers - is in how wireless charging works.
