The report covers conducted emission and radiated emission measurements, confirming that the S5C operates within the limits defined by the FCC CFR 47 Part 15 Subpart B standard for unintentional radiators.
Product Information
The equipment under test (EUT) is the S5C inflator pump, a portable cordless air compressor designed for inflating tires, sports equipment, and other inflatables. The product is manufactured by Guangdong Bestek Technology Co., Ltd. and marketed globally under the ETENWOLF brand.

| Model Number | S5C |
| Trade Mark | N/A |
| Applicant | Guangdong Bestek Technology Co., LTD |
| Applicant Address | No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R. China |
| Manufacturer | Guangdong Bestek Technology Co., LTD |
| Manufacturer Address | No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R. China |
| Operating Mode 1 | Charging |
The S5C is classified as an unintentional radiator under FCC rules, meaning it is not designed to emit radio frequency energy intentionally but must nonetheless comply with emission limits to avoid interference with other devices and radio services.
Key Details
The test report is structured across two primary emission test categories: conducted emission and radiated emission. Both measurement campaigns were completed between 2025-07-15 and 2025-07-16 at the Waltek HCT facility in Shenzhen.
Conducted Emission
Conducted emission testing measures unwanted electrical noise that the EUT injects back into the mains supply line. The test was performed in accordance with the limits specified in FCC CFR 47 Part 15 Subpart B. The S5C passed all conducted emission limits across the applicable frequency range.
| Test Item | Standard Reference | Result |
|---|---|---|
| Conducted Emission – AC Mains Port | FCC CFR 47 Part 15 Subpart B | Pass |
Radiated Emission
Radiated emission testing measures electromagnetic energy radiated from the EUT and its connected cables. The measurement uncertainty, corrected amplitude, and margin calculations are documented in Sections 4.1 through 4.8 of the full report. The S5C passed all radiated emission limits.
| Test Item | Standard Reference | Result |
|---|---|---|
| Radiated Emission – Open Area / Semi-Anechoic Chamber | FCC CFR 47 Part 15 Subpart B | Pass |

Standards & Compliance
The S5C inflator pump was evaluated against the following regulatory standard for the United States market:
| Standard | Full Title | Scope |
|---|---|---|
| FCC CFR 47 Part 15 Subpart B | Code of Federal Regulations, Title 47, Part 15, Subpart B – Unintentional Radiators | Conducted and radiated electromagnetic emission limits for digital and electronic devices sold in the United States |
FCC Part 15 Subpart B applies to any electronic device that, as a byproduct of its intended function, generates and can radiate radio frequency energy. Compliance with this subpart is mandatory for products placed on the US market and is enforced by the Federal Communications Commission (FCC).
The test report form used is TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01, a standardized reporting template aligned with FCC laboratory accreditation requirements. The decision rule applied during testing is documented in Section 2.6 of the full report, ensuring measurement uncertainty is properly accounted for in the pass/fail determination.
The laboratory applied its internal procedure reference HCT/RF-23-21 throughout all test phases, covering both conducted and radiated emission measurements.

How to interpret the answer
A technical document answers a bounded question. A positive test result means the submitted sample met the named requirement under the recorded method; it does not automatically establish legal market access, lifetime reliability, safe use in every environment, or equivalence to an untested revision. When a question goes beyond the source scope, say that the detail is not documented here and request the applicable companion evidence.
What this document does not prove
This rewrite does not create a new certification, warranty, regulatory filing, or product specification. It does not prove that a different model, supplier, battery cell, firmware build, or bill of materials has the same result. It also does not replace the model-specific user manual or advice from a qualified compliance, transport, or safety professional.
Practical review checklist
| Review item | Question to answer before relying on the page |
|---|---|
| Identity | Does the label and shipped configuration match the source sample? |
| Evidence | Can the report, workbook, manual, or MSDS be retrieved from the source notes? |
| Scope | Is the claim limited to the named method, threshold, date, and sample? |
| Change control | Have materials, suppliers, firmware, battery cells, or construction changed? |
| Human action | Has an editor checked the original document before publishing? |
Frequently Asked Questions
Does this page apply to every version of the product?
No. Use it for the exact model and configuration documented in FCC EMC Test Report – ETENWOLF S5C Inflator Pump | Reference WTH25H07183674E; later revisions require a documented equivalence review.
Can this result be used as a general safety or legal guarantee?
No. The result is evidence for a bounded technical scope. Other requirements may need separate EMC, chemical, battery, transport, or operating documents.
What if the question asks for a value that is not shown?
Do not infer it. State that the value is not documented in this source record and request the original evidence or a qualified review.
Why keep the original document after publishing?
Because the published rewrite is an explanation. The original report or manual remains the authoritative record for traceability, audits, customer support, and change control.
