Operating Frequency is 326.5KHz (2) Output power from each primary coil is less Yes. The maximum power is 5 Watts than or equal to 15 watts. (3) The transfer system includes only single Yes. The system includes one single primary and primary and secondary coils. This includes secondary coil and the device is designed to charging systems that may have multiple primary charge a single client coils and clients that are able to detect and allow coupling only between individual pairs of coils. (4) Client device is placed directly in contact with Yes. The client device is placed directly in contact the transmitter. with the transmitter. (5) Mobile exposure conditions only (portable Yes. Mobile exposure condition apply. exposure conditions are not covered by this exclusion). (6) The aggregate H-field strengths at 15 cm Yes.

REPORT NO: 12936083-E2V2 DATE: AUGUST 29, 2019 EUT: MAGNETIC CHARGING CABLE MODEL NAME: A2255 5. EQUIPMENT UNDER TEST 5.1. DESCRIPTION OF EUT The EUT is a magnetic charging cable which has a single inductive charging coil to charge Apple Watch. The charging frequency is 326.5 kHz, and the maximum power consumption is 5W in charging status. 5.2. WORST-CASE CONFIGURATION AND MODE The EUT is a single frequency magnetic charger enclosed in stainless steel case with different cable length USB -A type. For operation mode, it was tested with model A2095, a big watch. A2095 was chosen to test as the worst case condition since it has max load overall, hence all final data for operational mode represents EUT with the big watch. Config Mode Descriptions 1 Standby EUT Alone powered by AC/DC adapter 2 Operating EUT and Watch (big) powered by AC/DC adapter Note that the EUT was tested as standby and operation modes.
