Suzhou Yoshino Power Technology Co. Ltd. Attention: Certification reviewer RE: Request for Confidentiality FCC ID: 2BAU4- To Whom It May Concern: Permanent Confidentiality [Complete this section if permanent confidentiality is requested] Request to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: [Select one or more of items below, as appropriate] Schematics Block Diagrams Operational Description Parts List Internal Photos (see note) Users Manual (see note) Note 1: Internal Photos may be held confidential 1) if the circuit board or internal components are not accessible to users. For example, it is acceptable if the circuit board is enclosed in epoxy. 2) Also, it is acceptable if the device is not accessible to the public, for example, a device mounted on the top of a large tower (or in a fenced enclosure) such that it is only serviceable by professional designated technicians under a Non-Disclosure Agreement (NDA). All sales for these devices must be under a NDA restricting the disclosure of the propriety information, including internal photos. Users Manual may be held confidential only when the manual contains proprietary technical information intended for professional technicians obligated under a NDA. All sales and distribution of the user’s manual must be under a NDA that restricts the disclosure of the information. In the application cover letter requesting permanent confidentiality the following additional description and the NDA exhibit is required: 1. Describe in detail how internal photos and/or users manual information are controlled to prevent them from becoming public or disclosed to unauthorized persons. 2. Describe how public access is restricted for products serviceable by professional designated technicians. 3.

INTERTEK TESTING SERVICES FCC ID: 2BAU4-B4000SST 1 RF Exposure The equipment under test (EUT) is Portable Power Station with Wireless Charging function operating 111KHz-205KHz, 2.4G WIFI function operating in 2412-2462MHz and BT(BLE) function operating in 2402MHz~2480MHz. The EUT is powered by AC Input: 100-120VAC, 50/60Hz or Car Input: 12VDC/10A, 120W Max; or Solar Input: 12-60VDC/10A, Max, 600W Max . For more detail information pls. refer to the user manual. Wireless Charging: Antenna type: Integral Antenna(embedded coil antenna) The maximum H-Field Strength of the EUT is: 0.0947A/m. 2.4GHz WiFi: Antenna Type: Integral Antenna. Antenna1 Gain: 3.96dBi. Modulation Type: BPSK, QPSK, 16QAM, 64QAM, CCK, DQPSK, DBPSK and DSSS. According to FCC Part 2.1091, this unlicensed transmitting devices is categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use, According to the KDB 447498 and OET 65, the simple calculation as below: The source-based time averaged maximum radiated power = 20dBm +3.96dBi = 23.96dBm = 248.886mW From above data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna for 2.4GHz band can be calculated according to OET 65 as follow: = 248.886mW/ 4πR^2 = 0.0495 mW/cm^2 <1mW/cm^2 INTERTEK TESTING SERVICES FCC ID: 2BAU4-B4000SST 2 The MPE limit is 1.0 mW/cm^2 for general population and uncontrolled exposure in the WIFI frequency range according to FCC Part 1.1310. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structure and body of the user or nearby persons. BT(BLE): Antenna Type: Integral Antenna. Antenna1 Gain: 3.96dBi. Modulation Type: GFSK. According to FCC Part 2.1091, this unlicensed transmitting devices is categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use, According to the KDB 447498 and OET 65, the simple calculation as below: The source-based time averaged maximum radiated power = 6.0dBm +3.96dBi = 9.96dBm =9.9083mW From above data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna for 2.4GHz band can be calculated according to OET 65 as follow: = 9.9083mW/ 4πR^2 = 0.00197 mW/cm^2 <1mW/cm^2 The MPE limit is 1.0 mW/cm^2 for general population and uncontrolled exposure in the WIFI frequency range according to FCC Part 1.1310. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structure and body of the user or nearby persons. Simultaneous: BT antenna and 2.4G WiFi antenna can not transmit Simultaneous; For Simultaneous transmitting of 2.4GHz WiFi +Wireless Charging and BT+Wireless Charging, According to 865664D02 2.2 d) 1): 2.4GHz WiFi +Wireless Charging: The sum of the ratios of the spatially averaged results to the applicable frequency dependent MPE limits = 0.0495/1 + 0.0947/1.63 = 0.1076 < 1 BT+Wireless Charging: The sum of the ratios of the spatially averaged results to the applicable frequency dependent MPE limits = 0.00197/1 + 0.0947/1.63 = 0.0601 < 1 INTERTEK TESTING SERVICES FCC ID: 2BAU4-B4000SST 3 Since the sum of the MPE ratios for all simultaneously transmitting antennas incorporated in the device is ≤ 1.0, the EUT is considered to satisfy MPE compliance for simultaneous transmission operations. The following RF exposure statement or similar sentence is proposed to be included in the user manual: “FCC RF Radiation Exposure Statement Caution: This Transmitter must be installed to provide a separation distance of at least 20 cm from all persons.” -End-
