- Overall Test Result: Pass
The report covers both conducted emission and radiated emission measurements performed on the Equipment Under Test (EUT), confirming that the product meets all applicable FCC Part 15 Subpart B limits.
Product Information
The Equipment Under Test (EUT) evaluated in this report is the ETENWOLF Air3, a compact portable blowing pump designed for inflation tasks including vehicle tyres, bicycle tyres, sports equipment, and other inflatable items.
| Field | Detail |
|---|---|
| Product Name | Portable Blowing Pump |
| Model Number | Air3 |
| Trade Mark | N/A |
| Applicant | Guangdong Bestek Technology Co., Ltd. |
| Manufacturer | Guangdong Bestek Technology Co., Ltd. |
| Applicant / Manufacturer Address | No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R.China |
| Operating Modes | Mode 1: Charging; additional operating modes as defined in the full report |
The Air3 is classified as an unintentional radiator under FCC rules, meaning it does not intentionally transmit radio frequency energy but must still comply with emission limits to avoid interference with licensed radio services.
Key Details
The test report covers two primary EMC test disciplines: Conducted Emission and Radiated Emission. Below is a summary of the key test parameters and findings from report WTH25H07182969E.
Conducted Emission (Section 3)
| Parameter | Detail |
|---|---|
| Frequency Range | As defined by FCC CFR 47 Part 15 Subpart B conducted limits |
| Measurement Uncertainty | Documented in Section 3.1 of the full report |
| EUT Setup | Per Section 3.3 — standard conducted emission bench configuration |
| Instrument Setup | Per Section 3.4 |
| Test Result | Pass |
Radiated Emission (Section 4)
| Parameter | Detail |
|---|---|
| Frequency Range | As defined by FCC CFR 47 Part 15 Subpart B radiated limits |
| Measurement Uncertainty | Documented in Section 4.1 of the full report |
| EUT Setup | Per Section 4.3 — open area test site or equivalent shielded enclosure |
| Corrected Amplitude & Margin | Calculated per Section 4.6; all margins confirmed positive |
| Test Result | Pass |
Test Personnel
| Role | Name |
|---|---|
| Tested By | Snow Zeng |
| Approved By | Tony Wu |
Decision rules for pass/fail determination were applied per Section 2.6 of the report. No equipment modifications were required (Section 2.3). Supporting photographs of the EUT and test setup are included in Appendix A and Appendix B of the full report respectively.
Standards & Compliance
The Air3 was evaluated against the following regulatory standard:
| Standard | Scope | Authority |
|---|---|---|
| FCC CFR 47 Part 15 Subpart B | Unintentional radiators — conducted and radiated emission limits | Federal Communications Commission (FCC), USA |
FCC Part 15 Subpart B sets mandatory emission limits for digital devices and other electronic equipment that may unintentionally generate radio frequency energy. Compliance ensures the product does not cause harmful interference to authorized radio communications services operating across the United States.
The test methodology followed the procedures outlined in Test Report Form TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01, covering:
- Conducted emission measurement procedures (Section 3.5)
- Radiated emission measurement procedures (Section 4.5)
- Application of the laboratory’s documented decision rule (Section 2.6)
- Measurement uncertainty budgets for both conducted and radiated tests (Sections 3.1 and 4.1)
All test equipment used during the evaluation is listed with calibration details in Sections 3.6 and 4.7 of the full report.
Validity & Certification Body
This FCC SDoC test report was issued on 2025-07-25 and supports the applicant’s Supplier’s Declaration of Conformity for the Air3 portable blowing pump.

| Regulatory Framework | FCC SDoC — self-declaration by the responsible party based on this test report |
Under the FCC SDoC framework, the manufacturer or importer (responsible party) declares conformity based on test results from an accredited laboratory. This report serves as the technical basis for that declaration. The report remains valid as long as the product design and manufacturing process remain unchanged from the tested configuration.
Frequently Asked Questions
- What does the FCC SDoC test result mean for the ETENWOLF Air3?
-
A passing result on report WTH25H07182969E confirms that the Air3 portable blowing pump meets the conducted and radiated emission limits defined in FCC CFR 47 Part 15 Subpart B. This means the product can be legally marketed and sold in the United States without causing harmful interference to licensed radio services.
- What is the difference between FCC SDoC and FCC ID certification?
-
FCC ID certification requires third-party review and assignment of an FCC ID number, typically required for intentional radiators such as Wi-Fi or Bluetooth devices. FCC SDoC (Supplier’s Declaration of Conformity) applies to unintentional radiators like the Air3, where the manufacturer or importer self-declares conformity based on accredited laboratory test results — in this case report WTH25H07182969E issued by Waltek Testing Group HCT.
- Which emissions were tested in report WTH25H07182969E?
-
The report covers two emission categories required by FCC CFR 47 Part 15 Subpart B: conducted emissions (interference transmitted back through the power line) and radiated emissions (electromagnetic energy radiated through the air). Both tests returned a Pass result for the Air3.
- Does the FCC SDoC certification cover all markets globally?
-
No. The FCC SDoC certification covers the United States market only. For sales in the European Union, the product requires CE marking with EMC Directive compliance. For South Korea, KC certification is required. ETENWOLF pursues the relevant certifications for each target market independently.
