Supporters of the wireless charger love it, but other people question its slow charging speed and short charging distance. 4 main points you need to pay attention to when choosing a wireless charger:
1. Charging power of 4 main points to pay attention to when purchasing a wireless charger:
The current mainstream wireless chargers mainly use Qi’s Basic Power Profile configuration, which supports 10W output. Calculating the conversion rate, it is roughly equivalent to 5W~7.5W received power. It can match iPhone 8/8 Plus and iPhone X. Although it is compatible with Qi standard, not all Qi wireless chargers can make it reach 7.5W fast charge.
2. The charging distance of 4 main points to pay attention to when purchasing a wireless charger:
The maximum charging distance of the Qi wireless charger is about 10 mm, so it can be charged with a protective cover, and the phone does not need to be “taken off” to charge.
With the development and iteration of the Qi standard, the cost of wireless charging technology has slowly come down. There are more and more products of around 100 yuan, and the experience cost can be regarded as low. At present, Xiaomi and Huawei have begun to try to add wireless charging to its products. It can be expected that the wireless charging function will be more popular in the next two years.
3. Four key points to pay attention to when purchasing a wireless charger: heat dissipation:
The output power of the wireless charger is not constant, and the peak power mainly depends on the design material and heat dissipation method of the wireless charger. We recommend buying a model equipped with an active cooling fan. Although it is thicker, it generally outputs peak power. The time is also longer.
4. FOD foreign body detection: 4 points to pay attention to when purchasing a wireless charger:
FOD foreign body detection should be the most basic safety function of the wireless charger. When a metal foreign body is sandwiched between the mobile phone and the wireless charger, the wireless charger will detect and cut off the power to prevent the metal foreign body from overheating.
