Document DEVICE REPORTGetApplicationAttachment.html?id=8362950America Ugreen Limited 108 West 13Th Street, Wilmington, Delaware19801, United States Date: June 5, 2025 FCC ID: 2BOTB-W526 Model Number: W526 To: Federal Communication Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21048 To Whom It May Concern, We, America Ugreen Limited hereby declare that our product (2-in-1 Magnetic Wireless Charger) Model Number: W526 meet item 5.2 of KDB 680106v04 as follow; Requirements of KDB 680106 D01 Yes / Description No The device operates in the Power transfer frequency is less than 1 MHz Yes frequency range 110.1 KHz 205 KHz. The output power from each transmitting element (e.g., coil) is less than or equal to 15 Yes watts. The device contains two transmitter coisl, the maximum output power of coil is 7.5W. A client device providing the maximum permitted load is placed in physical contact Client device is placed with the transmitter (i.e., the surfaces of the Yes directly in contact with the transmitter and client device enclosures need transmitter. to be in physical contact) Only §2.1091- Mobile exposure conditions apply (i.e., this provision does not cover § 2.1093-Portable exposure conditions). Mobile exposure condition Yes only. The E-field and H-field strengths, at and beyond 20 cm surrounding the device surface, are demonstrated to be less than 50% of the applicable MPE limit, per KDB 447498, Table 1. These measurements shall be taken along the principal axes of the device, with one axis oriented along the direction of the Yes estimated maximum field strength, and for three points per axis or until a 1/d (inverse distance from the emitter structure) field The E-field and H-field strengths, at and beyond 20 cm surrounding the device surface, are demonstrated to be less than 50% of the applicable MPE limit strength decay is observed. Symmetry considerations may be used for test reduction purposes. The device shall be operated in America Ugreen Limited 108 West 13Th Street, Wilmington, Delaware19801, United States documented worst-case compliance scenarios (i.e., the ones that lead to the maximum field components), and while all the radiating structures (e.g., coils or antennas) that by design can simultaneously transmit are energized at their nominal maximum power. For systems with more than one radiating structure, the conditions specified in (5) must be met when the system is fully loaded (i.e., clients absorbing maximum power available), and with all the radiating structures operating at maximum power at the same time, as per design conditions. If Only one radiating structure the design allows one or more radiating Yes and tested at maximum structures to be powered at a higher level Output Power while other radiating structures are not powered, then those cases must be tested as well. For instance, a device may use three RF coils powered at 5 W, or one coil powered at 15 W: in this case, both scenarios shall be tested Please contact me if you have any question.
