Smartphone charging: proper plug order and low‑cost fast charger

Experts advise that the safest way to plug in a mobile phone is to first connect the charger to the wall outlet and only then attach the cable to the device. This sequence allows the adapter to stabilise the electricity before it reaches the phone, reducing voltage spikes and limiting micro‑arcing that can gradually wear out charging ports and battery contacts. When unplugging, they recommend removing the cable from the phone before pulling the charger from the socket, which further protects the connectors.

Action stores in Portugal are promoting a 45‑watt GaN (gallium‑nitride) wall charger called the Re‑load GaN³ Pro, priced at €4.79. The charger features a USB‑C and a USB‑A port, can charge two devices simultaneously, and claims up to 75% faster charging compared with standard adapters. Its GaN technology keeps the unit compact and cool, making it suitable for travel and everyday use.
