Both are within the safe range, and the magnetic field generated by the charger is very weak, which can charge the device but will not affect nearby credit cards, video tapes and other items that use magnetic data recording. However, try to avoid direct contact with the charging platform when charging.

Wireless charging technology was granted 20 patents in 2007, and a variety of devices can use a charging base station, mobile phones, MP3 players, power tools and other power adapters. By using the magnetic field generated between the coils to transmit power, inductive coupling technology will act as a bridge between the charging base station and the device. Most current chargers, such as the iPod and iPhone, charge the device's internal battery through direct contact with a metal wire. The advantage of wireless charging technology is its convenience and versatility. The disadvantages are low efficiency and can only provide electrical energy.

The body's response to electric fields is strong, but the body's response to magnetic fields is almost non-so this system does not affect human health.

As an electronic charging product, the charger itself cannot avoid radiation, so it is inevitable that the wireless charger has radiation. However, the current power of the wireless charger is very small, the charging time is longer, the radiation generated is also small, and it should not cause great harm to people.
