Phone charging guides
A phone only charges at its top rate when the charger, the cable, and the phone agree on how, which makes charging gear the category where the spec sheet matters most. The USB-C fast charger guide explains USB Power Delivery, PPS, and AVS, and lists the wired rates Apple, Samsung, and Google publish for their current phones. MagSafe and Qi2 explained covers magnetic wireless charging, the 15W and 25W tiers, and how to confirm that a charger is certified.
Power banks and flying covers capacity, watt-hours, and the airline rules that changed in March 2026. Cables have their own guide in the accessories section, choosing a USB-C cable.
