Belkin International, Inc. 555 S. Aviation Blvd., Suite 180, El Segundo, CA 90245, USA 2024/4/2 To: Federal Communicaons Commission 7435 Oakland Mills Road Columbia, MD FCC ID: K7SBPD007 To Whom It May Concern:
This le&er is to ascertain that (Belkin International, Inc.) Product (BoostCharge Pro Magnetic Power Bank 8K) Wireless Charger (BPD007), has been the units used for conducng FCC compliance tesng, and it meets KDB 680106 D01 V04 Clause 5(2) all 6 condions except criteria (4). Yes No Criteria Requirements
(1) The power transfer frequency is below 1 MHz.
(2)
(3)
(4)
(5)
(6) The output power from each transmi<ng element (e.g., coil) is less than or equal to 15 wa&s. A client device providing the maximum permi&ed load is placed in physical contact with the transmi&er (i.e., the surfaces of the transmi&er and client device enclosures need to be in physical contact) Only 2.1091-Mobile exposure condions apply The E-eld and H-eld 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 direcon of the esmated maximum eld strength, and for three points per axis or unl a 1/d (inverse distance from the emi&er structure) eld strength decay is observed. Symmetry consideraons may be used for test reducon purposes. The device shall be operated in documented worst-case compliance scenarios (i.e., the ones that lead to the maximum eld components), and while all the radiang 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 radiang structure, the condions specied in (5) must be met when the system is fully loaded (i.e., clients absorbing maximum power available), and with all the radiang structures operang at maximum power at the same me, as per design condions. Explanaon The power transfer frequency are 127.7kHz/360.0kHz The maximum output power of each coil is equal to 15 wa&s. Portable exposure condions See the test report. The DUT(Device Under Test) includes only one radiang structure, and operang at maximum power Belkin International, Inc. 555 S. Aviation Blvd., Suite 180, El Segundo, CA 90245, USA If the design allows one or more radiang structures to be powered at a higher level while other radiang 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. If you have any queson or concerns, please contact us.
