Wireless chargers buying guide

Wireless charging is convenient but slower and warmer than a cable, so buy for the habit it suits.

1. Check that the charger supports the standard your phone uses (Qi or Qi2 with magnets) and its top wattage.
2. The power adapter often is not included, and a weak adapter cripples a fast charger.
3. Thick cases and metal plates can block charging; a good pad tells you where to place the phone.
4. Stands let you use the phone while it charges; flat pads suit the bedside.
5. Look for foreign-object detection and temperature protection.

Common mistake: Expecting cable-speed charging from a basic 5 W pad.
