4 Key Points How to Choose Right Wireless Charger for your Phone

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

be charged.

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.
