This document presents the RF Exposure Evaluation for the S20 car mobile phone holder wireless charging device, identified by FCC ID: 2A4YM-S20. The evaluation was conducted to ensure compliance with RF exposure limits as specified in Part 2.1091 and KDB 680106 D01 v04. The device supports wireless charging at various power levels: 5W, 7.5W, 10W, and 15W. Testing was performed in a continuously wireless charging mode, with input power supplied at 5V-2A and 9V-2A.
The evaluation involved measuring electric and magnetic field strengths at a distance of 20 cm from all sides and the top of the EUT (Equipment Under Test). Measurements were taken at five points (A, B, C, D, E) surrounding the device. The highest emission levels were recorded and compared against permissible exposure limits. The test setup and procedure adhered to KDB 680106 D01v04 guidelines. The results indicate compliance with RF exposure limits for general population/uncontrolled exposure.
The report details the test equipment used, including the Exposure Level Tester, Magnetic field probe, and Field Probe. Uncertainty analysis is also provided. The test results show the electric and magnetic field strengths at each measurement point, confirming that the device operates within the specified limits.
