Within the safe range, the magnetic field generated by the charger is very weak, which can charge the equipment but will not affect nearby credit cards, video tapes and other items that use magnetic recording data. However, when charging, try to avoid direct contact with the charging platform.
Charging technology obtained 20 patents in 2007. A variety of devices can use a charging base station, mobile phone, MP3 player, power tools and other power adapters. By using the magnetic field generated between coils to transmit electric energy, inductive coupling technology will become a bridge between charging base stations and equipment. Most current chargers, such as iPod and iPhone, charge the built-in battery of the device through direct contact with metal wires. The advantage of wireless charging technology lies in its convenience and versatility. The disadvantage is that it is inefficient and can only provide electricity.
The body reacts strongly to the electric field, but hardly to the magnetic field, so this system will not affect human health.
As an electronic charging product, the charger itself cannot avoid radiation, so it is inevitable that the charger has radiation. However, at present, the power of the charger is very small, the charging time is long, and the radiation generated is also small. It should not cause great harm to people.
