Do you want to use a charger with solar cells on the plane?
When we consider whether an electronic product will interfere with other equipment, we mainly look at whether it directly or indirectly emits harmful electromagnetic waves. The mobile phone itself is directly used to transmit signals, so it cannot be used on airplanes. Although some other products do not emit directly, they emit indirectly. For example, the cell phone charger we use has a switching power supply. The circuit operates at several hundred kHz and also emits high-frequency electromagnetic interference to the outside world. during operation. The technical terms are called conducted emission and radiated emission. However, conventional products must have absorption circuits to reduce or absorb this interference below standards.my nationals.
If it is a simple solar charging circuit, of course there will be no interference. Whether it is equipped with a switching power supply, it depends on the performance of the switching power supply. Generally speaking, since the power is relatively low, there are not many problems in use. If it’s a particularly cheap product, it’s best to be careful.
