Document Overview
This article covers the official FCC electromagnetic compatibility (EMC) test report issued for the P300 / P300 PLUS inflator pump. The document is classified as a Test Report under reference number WTH25H09255940E (internal reference: WTH25H09255940), prepared in accordance with FCC CFR 47 Part 15 Subpart B — the United States federal standard governing unintentional radiators and their limits for both conducted and radiated emissions.
The report was issued on 2025-09-29 by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an accredited third-party electromagnetic compatibility testing laboratory located in Shenzhen, Guangdong, China. The test report form number is TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01, and the overall test result is Pass. The scope of the assessment covers conducted emissions and radiated emissions generated by the equipment under test (EUT) during normal operating conditions.
Product Information
The equipment under test is the P300 / P300 PLUS inflator pump, a portable electric inflation tool distributed under the ETENWOLF brand. The product is manufactured and supplied by Guangdong Bestek Technology Co., Ltd., whose registered address is No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R. China. The same entity acts as both applicant and manufacturer on the certification record.

The P300 / P300 PLUS is designed for inflating vehicle tires, sports equipment, and other inflatables. Its internal motor and power circuitry constitute the primary sources of electromagnetic emissions evaluated during this test campaign.
Key Details
The test campaign ran from 2025-09-25 to 2025-09-28, with the sample received on 2025-09-23 and the final report issued on 2025-09-29. Two main emission categories were assessed: conducted emissions and radiated emissions. The following table summarises the key test and report parameters.

The test report is structured across 26 pages and includes the following major sections: General Information, System Test Configuration, Conducted Emission measurements and data, Radiated Emission measurements and data, EUT photographs (Appendix A), and Test Setup photographs (Appendix B). The conducted emission section documents measurement uncertainty, applicable limits, EUT setup, instrument setup, test procedure, equipment list, and tabulated test data. The radiated emission section similarly documents uncertainty budgets, limits, antenna and receiver configurations, corrected amplitude and margin calculations, and full test data tables.
Standards & Compliance
The P300 / P300 PLUS inflator pump was evaluated against the following regulatory standard and associated technical requirements.
| Standard | Scope | Result |
|---|---|---|
| FCC CFR 47 Part 15 Subpart B | Unintentional radiators – conducted and radiated emission limits for the United States market | Pass |
Under FCC CFR 47 Part 15 Subpart B, unintentional radiators such as the P300 / P300 PLUS must demonstrate that electromagnetic emissions on the AC mains (conducted emissions) and through the air (radiated emissions) remain below the prescribed Class B limits. Class B limits apply to devices intended for use in residential environments, providing a more stringent level of protection against interference to radio communications than Class A limits.
The conducted emission tests measure noise current or voltage injected back onto the power supply lines in the frequency range typically from 150 kHz to 30 MHz. The radiated emission tests measure the electric field strength radiated by the EUT, typically from 30 MHz to 1 GHz (and above where required), at a defined measurement distance. Both sets of measurements incorporate a documented measurement uncertainty budget, and the decision rule applied for pass/fail determination is recorded within the report body under Section 2.6.
Validity & Certification Body

FCC test reports issued by accredited laboratories serve as the technical basis for a Declaration of Conformity (DoC) or FCC filing. The validity of this report is contingent on the product remaining unchanged from the tested sample configuration. Any design modification to the circuitry, enclosure, power supply, or firmware that could affect electromagnetic emission characteristics would require re-evaluation. The report covers the specific model and configuration described in Section 1.1 of the original document and should be read in conjunction with the EUT photographs in Appendix A and the test setup photographs in Appendix B.
Frequently Asked Questions
- What does the FCC CFR 47 Part 15 Subpart B test verify for the P300 / P300 PLUS inflator pump?
- The test verifies that the P300 / P300 PLUS inflator pump does not generate electromagnetic interference above the limits set by the US Federal Communications Commission for unintentional radiators. It covers both conducted emissions — noise fed back into the power supply lines — and radiated emissions — electromagnetic fields emitted through the air. A passing result means the product meets FCC Class B requirements and is suitable for sale and use in the United States.
- What is the significance of reference number WTH25H09255940E?
- WTH25H09255940E is the unique test report reference number assigned by Waltek Testing Group HCT (Shenzhen) Co., Ltd. to this specific EMC assessment. It can be used to trace the full 26-page report, including all raw measurement data, test equipment calibration records, uncertainty budgets, and photographic documentation of the EUT and test setup. The companion internal reference is WTH25H09255940.
- Does a passing FCC Part 15 Subpart B result mean the P300 / P300 PLUS is FCC authorised for sale in the US?
- A passing test report is a required technical foundation for FCC market authorisation, but the authorisation process also involves filing a Supplier’s Declaration of Conformity (SDoC) or obtaining a Certification (depending on device category), labelling the product with the FCC ID or compliance statement, and maintaining the technical documentation on file. This test report supports that process for the P300 / P300 PLUS.
- Who prepared and approved the FCC EMC test report for the P300 / P300 PLUS?
- The report was prepared by Snow Zeng and approved by Tony Wu at Waltek Testing Group HCT (Shenzhen) Co., Ltd. The laboratory’s internal form reference is HCT/RF-23-21 and the test report form number is TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01.
