What should I pay attention to when buying magnetic wireless charger 25W products?
1. FOD foreign object detection
FOD foreign object detection should be the most basic safety function of the magnetic wireless charger 25W products. When there is a metal foreign object between the mobile phone and the wireless charger, the magnetic wireless charger 25W products will sense it and cut off the power to prevent the metal foreign object from overheating.
However, the FOD function cannot be judged just by looking at the promotional parameters, and the specific performance can only be seen through actual measurement. Most wireless chargers on the market are qualified in the detection of FOD foreign objects.
2. Heat dissipation problem
The output power of the magnetic wireless charger 25W products is not constant, and the peak power mainly depends on the design materials and heat dissipation methods. We recommend buying models equipped with active cooling fans. Although they are thicker, the time to output peak power is generally shorter longer.
3. Charging distance
The maximum charging distance of the magnetic wireless charger 25W products is about 10 mm, so it can also be charged with a protective case.
With the development and iteration of the Qi standard, the cost of wireless charging technology has gradually come down. There are more and more products around 100 yuan, and the experience cost can be regarded as low.
