Wireless charger, Many people think it is a great technology, but another person questioned that it
has a slow charging speed and a short charging distance. Whether you love or not, you can’t deny
that wireless charging has become very popular. Yuda phone charger supplier give some sugge-
stions to users who need to purchase, 4 key points how to choose right wireless charger for your phone:
First, wireless charger charging power:
Currently popular wireless chargers mainly use Qi’s Basic Power Profile configuration, which supports
10W output, and the real conversion rate is about 5W~7.5W. It can match the iPhone 8/8 Plus and
iPhone X Qi standards, but not all Qi wireless chargers can make it reach 7.5W fast charge.
Second, wireless charger charging distance:
Qi wireless charger’s maximum charging distance is about 10 mm, so each protective case can also
With the development of the Qi standard, the cost of wireless charging technology has gradually
dropped, and more and more products are around 100 yuan, and the experience cost is low. At
present, Xiaomi Huawei has begun to try to join the wireless charging industry, and it is expected
that the wireless charging market will become very hot in the next two years.
Third, the wireless charger cooling problem:
The output power of the wireless charger is not constant, and the peak power is mainly determined
by the design material and heat dissipation method of the wireless charger. We recommend to
purchase a model with an active cooling fan, although thick. However, the time to output peak power
is also longer.
Fourth, wireless charger FOD foreign object detection:
FOD foreign object detection should be the most basic safety function of wireless chargers. When a
metal foreign object is caught between the mobile phone and the wireless charger, the wireless
charger senses and de-energizes to prevent metal foreign matter from overheating.
However, the FOD function can not be judged by looking at the product parameters. Only the actual
measurement can be used to see the specific performance. Most of the wireless chargers on the
market are qualified for FOD foreign object detection.
