Today to share the knowledge of wireless charging FCC update SAR, which will also explain the mobile phone upgrade wireless charging, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>First of all, not all wireless chargers on the market can be competent for watch charging. Many products do not clearly label the radiation value, which is in aIt's worrying to some extent. 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.
Taking 1000mAh capacity lithium battery as an example, the radiation of wireless charger is calculated. 50% charging capacity is about 7~8Wh. If it is required to be full for about two hours, the maximum charging power should reach at least 1W (the maximum power of the GSM900 mobile phone is about 2W); On account ofThe wireless charging method of the phone is to place the phone above the charger rather than inside, so the radiation leakage rate may be not small.
Under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.
Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers are not yet available5V / 5A or 5V / 4.5A super fast charge, compatible with 9V / 2A fast charge.
2, if referring to vivo mobile phone, vivo/iQOO currently supports wireless charging devices are: X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro. If you have more questions, you can enter vivo official website /vivo mall APP- my - online customer service or vivo official websiteWeb version -- bottom of the slide -- online customer service -- enter the manual customer service to enter the consultation.
3, at present, vivo/iQOO devices have supported wireless charging. Here is a list of devices that currently support wireless charging: iQOO 11 Pro, X90 Pro, X90 Pro, X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro.
2, the average time for the FCC to accept ID applications is 60 days. At the end of the hearing,The FCC will send the Original Grant of the FCC ID to the applicant. After receiving the certificate, the applicant can sell or export the corresponding products. At least one qualified prototype should be provided for each certified model.
3, FCCID certification is specifically for wireless products, certificate issued by the United States TCB agency, when applying for certification, the first need for enterprises to apply for Code code, certification companies to complete product testing issued test reports, by the TCB agency audit in the issuance of certificates, this cycle is relatively long, about 4 weeks.
