1. First, the cityNot all wireless chargers on the surface are capable of charging the watch. Many products do not clearly label the radiation value, which is somewhat worrisome. Since the radiation standard of wireless charging technology has not yet been perfected, we need to be concerned that the current regulatory requirements, such as the Electromagnetic Radiation Protection Regulations, stipulate that the electromagnetic radiation of the user in continuous contact with the wireless charger within 24 hours shall not exceed the specific absorption rate (SAR) limit of 0.02W/kg.
2, taking the lithium battery with 1000mAh capacity as an example, the radiation of the wireless charger is calculated. 50% charging capacity is about 7~8Wh. If two are requiredThe maximum charging power should reach at least 1W (the maximum power of GSM900 mobile phone is about 2W). Since the wireless charging method of the phone is to place the phone above the charger rather than inside, the radiation leakage rate can be not small.
3, the test found: using a high-sensitivity radiation tester, the radiation value of the wireless charger is between 150 and 180, although compared to the 250 to 627 in front of the computer screen or the thousands of values when making a phone call, but the cumulative effect may not be ignored. At the same time, when wireless chargers, mobile phones, computers and other electronic devices are used in superposition, the radiation value will be displayedIncreasing.
4, according to the Electromagnetic Radiation Protection Regulations, the average radiation absorption rate of the whole body should be less than 0.02w /kg within 24 hours a day for 6 minutes. However, there are no specific standards for wireless charging. Experts say that while there are national standards for traditional mobile phone chargers, there should be national industry standards for emerging wireless charging devices as soon as possible. The Qi wireless charging standard uses a low frequency non-ionization frequency (110-205khz) that is harmless to the human body.
