FCC ID: 2ASJOSH001-2 Product Name: Power charging station RF Exposure Considerations 1. Measuring Standard KDB 680106 D01 RF Exposure Wireless Charging Apps v03 2. Requirements According to the item 5.2 of KDB 680106 D01v03: For device designed for typical desktop applications, RF exposure evaluation should be conducted assuming a user separation distance of 20cm (Top) and 15cm (Edge). E and H field strength measurements or numerical modeling may be used to demonstrate compliance. Measurements should be made from all sides and the top of the primary/client pair, with the 20cm(Top) and 15cm(Edge) measured from the center of the probe(s) to the edge of the device. Limits For Maximum Permissible Exposure (MPE)

FCC ID: 2ASJOSH001-2 Product Name: Power charging station 3. Test Setup Note: 1. The RF exposure test is performed in the shield room. 2. The test distance is between the edge of the charger and geometric centre of probe. 4. Test Equipment List Test Equipment Manufacturer Model No. Calibration Due Magnetic field meter NARDA ELT-400 Sep. 02, 2019

FCC ID: 2ASJOSH001-2 Product Name: Power charging station 5. Test Result The EUT does comply with item 5 KDB 680106 D01v03. (1) Power transfer frequency is less than 1MHz. (Conform) - The frequency for EUT is 110-205KHz. (2) Output power from each primary coil is less than or equal to 15 watts. (Conform) -10w max. (3) The transfer system includes only single primary and secondary coils. This includes charging systems that may have multiple primary coils and clients that are able to detect and allow coupling only between individual pairs of coils. (Conform) -only single coil. (4) Client device is placed directly in contact with the transmitter. (Conform) -yes, client device is put specification area of EUT directly. (5) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion.) (Conform) -yes, EUT work with plug in and AC power. (6) The aggregate H-field strengths at 15cm surrounding the device and 20cm above the top surface from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE limit. (Conform) -yes, please see data.
