Chargers

An iPhone and a Galaxy in the same household, or two phones for work and personal use—what should one shared charger support? iPhone 18 Pro's fastest charging needs AVS; Galaxy super fast charging needs PPS. What happens with a charger that supports only one, and why a charger with both plus a 5A cable is the pick, in a decision table.

Should you leave a USB phone charger plugged into the wall? Standby power with nothing attached, heat, and the 'tracking' phenomenon the Tokyo Fire Department warns about (dust plus moisture between plug blades igniting)—turned into a decision table for when to unplug, when it's fine, and what to clean and check.

Should your USB-C charger have one port or two to three? A multi-port charger splits its total wattage across devices, and plugging in a second device makes every port renegotiate power (on some units, charging pauses for a moment). From that mechanism: who each suits, who it doesn't, and how it fails, with 45W–100W examples.

Does an iPhone need an Apple charger? Third-party USB PD adapters fast-charge too—Apple says so. The real differences: ① iPhone 18 Pro needs a 60W+ adapter with AVS, ② MagSafe 25W needs certification, ③ cable limits (60W vs 240W), ④ safety marks (PSE, USB-IF). When genuine is worth it, when it isn't, and how each choice fails.

A decision guide that starts from what your device requests: iPhone 18 Pro / 17 / older, iPad, Android, MacBook Air / Pro and other laptops. Covers total vs single-port wattage on multi-port chargers, cable limits, and the common mistakes (buying by total, no PPS, no AVS), then points to the 65W / 100W / 140W comparisons.

What wattage charger should you buy for an iPad? Per Apple's official specs (Japan), every current iPad, iPad mini, iPad Air, and iPad Pro ships with a 20W USB-C Power Adapter, and only iPad Pro (M5) claims fast charging—up to 50% in about 30 minutes with a 60W+ adapter.
