Wireless phone chargers is a way to charge your phone without needing to plug it in with a cable. You place your device on a charging pad or stand, and it will start charging automatically using an electromagnetic field. A chip controls the charging process to ensure it's safe and doesn't damage your device. Learn more about how it works here.

Neither magnetic charging nor wireless chargers are particularly bad for batteries. A battery slowly wears as it is charged or discharged over time. Leaving devices always charging can be harmful to their batteries. It's recommended to unplug the device once it is charged. Learn more about safety here.

To use a wireless charger pad, first plug it into a power source and place your compatible device on the pad, making sure it's centered and aligned with any guidelines provided. Wait for the charging process to start, which may be indicated by a light or other indicator. It's important to note that not all devices are compatible with all wireless chargers, so check your device's specifications to ensure compatibility with the charger and the charging standard. 

Wireless charger pads use a technology called inductive charging to transfer energy wirelessly from the charger to the device being charged. This works through two coils, one in the charger and one in the device, that create an electromagnetic field. Most wireless chargers use MagSafe, Qi or Qi2 modules. Compatibility, charging speeds and other features vary based on the wireless charging technology. 

Wireless charging stands are similar to charging pads, but hold the device at an angle so it can be viewed while it charges. They work by using inductive charging, which transfers energy wirelessly from the charger to the device being charged. The charger contains a coil of wire that creates an electromagnetic field, and the device being charged contains a coil that picks up this field to charge the battery. Most charging stands use the Qi standard, which optimizes the charging process by adjusting power and speed, and the device can be used and viewed while it charges.
