| Product Name | Inflator Pump |
| Model Number | S6 |
| Brand / Trade Mark | ETENWOLF (filed as N/A on report cover; associated brand is ETENWOLF) |
| Applicant | Guangdong Bestek Technology Co., Ltd. |
| Manufacturer | Guangdong Bestek Technology Co., Ltd. |
| Manufacturer Address | No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R. China |
| Operating Modes Tested | Mode 1: Charging Mode; additional operating modes as defined in test configuration |
The ETENWOLF S6 is a battery-powered cordless inflator. During EMC testing, the device was evaluated across all relevant operating modes to ensure emissions remain within regulatory limits under realistic use conditions.
Key Details
The test report covers two primary EMC measurement categories required under FCC CFR 47 Part 15 Subpart B: conducted emissions and radiated emissions. Both test categories returned a passing result.
Conducted Emission Testing
Conducted emission testing measures unwanted electrical noise that a device injects back into the AC mains power line. For a cordless inflator operating from a battery or DC charging input, this test verifies that the device’s internal switching electronics do not generate excessive line-conducted interference. The test covered the frequency range applicable under Part 15 Subpart B limits.
| Test Category | Section Reference | Result |
|---|---|---|
| Conducted Emission | Section 3 of report WTH25H07183679E | Pass |
| Measurement Uncertainty Applied | Section 3.1 | Documented |
| Emission Limits Applied | Section 3.2 — FCC Part 15 Subpart B | Compliant |
| EUT Setup | Section 3.3 | Per standard configuration |
| Instrument Setup | Section 3.4 | Calibrated equipment used |
| Test Data | Section 3.7 (pages 10–12) | On file |
Radiated Emission Testing
Radiated emission testing measures electromagnetic energy radiated into free space from the device and its cables. The ETENWOLF S6 was tested at a calibrated test site with corrected amplitude and margin calculations performed to confirm compliance margins.
| Test Category | Section Reference | Result |
|---|---|---|
| Radiated Emission | Section 4 of report WTH25H07183679E | Pass |
| Measurement Uncertainty Applied | Section 4.1 | Documented |
| Emission Limits Applied | Section 4.2 — FCC Part 15 Subpart B | Compliant |
| EUT Setup | Section 4.3 | Per standard configuration |
| Test Receiver Setup | Section 4.4 | Calibrated receiver used |
| Corrected Amplitude & Margin | Section 4.6 | Positive margins confirmed |
| Test Data | Section 4.8 (pages 16–26) | On file |
Report Structure Summary
The full report (35 pages, reference WTH25H07183679E) includes Appendix A (EUT photographs, pages 27–33) and Appendix B (test setup photographs, pages 34–35), providing photographic evidence of the test configuration and physical product condition at the time of testing.
Standards & Compliance
The ETENWOLF S6 inflator pump was tested against the following regulatory standard:
| Standard | Full Title | Applicability |
|---|---|---|
| FCC CFR 47 Part 15 Subpart B | Federal Communications Commission Code of Federal Regulations Title 47, Part 15, Subpart B — Unintentional Radiators | Conducted and radiated emission limits for digital devices and unintentional radiators sold in the USA |
The test report form used is TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01, which is the standardized test report format accepted by the FCC for SDoC submissions. The decision rule applied for pass/fail determination is documented in Section 2.6 of the report.
Under the FCC SDoC framework, the manufacturer or importer (in this case Guangdong Bestek Technology Co., Ltd.) is responsible for ensuring ongoing compliance and retaining the test report as supporting documentation. The FCC SDoC process does not require a third-party certification body to grant a license; instead, it relies on the manufacturer’s declaration backed by accredited laboratory test data such as report WTH25H07183679E.
Validity & Certification Body
The test report WTH25H07183679E was prepared and approved by qualified personnel at Waltek Testing Group HCT (Shenzhen) Co., Ltd., a recognized EMC and RF testing laboratory.

FCC SDoC test reports do not carry a fixed expiration date in the same manner as some other certifications. However, the report remains valid as long as the product design and configuration remain unchanged from what was tested. Any hardware, firmware, or component changes that could affect EMC performance require re-evaluation. The report date of 2025-07-25 represents the baseline configuration for the ETENWOLF S6 at time of testing.
Frequently Asked Questions
- What does the FCC SDoC test report WTH25H07183679E confirm about the ETENWOLF S6?
-
Report WTH25H07183679E confirms that the ETENWOLF S6 inflator pump passed both conducted emission and radiated emission tests under FCC CFR 47 Part 15 Subpart B. This means the device does not emit electromagnetic interference above the legally permitted limits, making it eligible for sale and use in the United States under the FCC Supplier’s Declaration of Conformity framework.
- What is the difference between FCC SDoC and FCC ID certification?
-
FCC ID certification requires a third-party Telecommunications Certification Body (TCB) to formally authorize the device, and the FCC ID must be labeled on the product. FCC SDoC, which applies to the ETENWOLF S6, allows the manufacturer to self-declare conformity based on accredited laboratory test results without obtaining a formal FCC ID number. SDoC applies to unintentional radiators (devices that are not intentional radio transmitters) under Part 15 Subpart B.
- Which laboratory conducted the EMC testing for the ETENWOLF S6 and is it accredited?
-
The testing was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., located in Longgang District, Shenzhen, China. The laboratory prepared the report under internal reference HCT/RF-23-21. Waltek Testing Group is a recognized third-party test house serving international compliance markets. For the most current accreditation scope, contact the laboratory directly at [email protected] or call 400-0066-989.
- Does passing FCC Part 15 Subpart B mean the ETENWOLF S6 is approved for all global markets?
-
No. FCC Part 15 Subpart B compliance covers the United States market only. Other markets have their own EMC requirements — for example, the European Union requires CE marking under the EMC Directive, and South Korea requires KC certification. ETENWOLF pursues multiple certifications for its products to support global distribution. Check the product listing for the ETENWOLF S6 for the full list of applicable certifications.
