The certification scope covers conducted and radiated emissions testing to ensure the device complies with FCC CFR 47 Part 15 Subpart B requirements for unintentional radiators.
Product Information
Product Name: Inflator Pump / Cordless Tire Inflator
Model Number: S3
Applicant: Guangdong Bestek Technology Co., LTD
Manufacturer: Guangdong Bestek Technology Co., LTD
Manufacturing Location: No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R.China
The ETENWOLF S3 is a portable electric inflator pump designed for automotive tire inflation and other air pressure applications. As an electronic device with electrical components, it must comply with FCC regulations governing electromagnetic emissions to prevent interference with radio communications and other electronic equipment.
The device was evaluated in its typical operating configuration to ensure real-world compliance with federal emissions standards applicable to consumer electronic products marketed in the United States.
Key Details
The FCC certification testing evaluated the S3 inflator pump across multiple electromagnetic compatibility parameters:
| Test Parameter | Test Standard | Result |
|---|---|---|
| Conducted Emission | FCC CFR 47 Part 15 Subpart B | Pass |
| Radiated Emission | FCC CFR 47 Part 15 Subpart B | Pass |
Overall Test Result:PASS
Test Report Form: TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01
The testing was conducted in accordance with ANSI C63.4 measurement procedures, which define the methods for measuring radio-noise emissions from digital devices. All measurements were performed at an accredited test facility with calibrated equipment traceable to national standards.
The device demonstrated compliance with applicable limits for both conducted emissions (measured on AC power ports) and radiated emissions (measured at specified distances in an electromagnetically controlled environment).
Standards & Compliance
The certification testing was performed according to the following technical standards and regulatory requirements:
- FCC CFR 47 Part 15 Subpart B: Federal regulations governing unintentional radiators, which are electronic devices that generate radio frequency energy during operation but are not intended to transmit radio signals. This standard sets maximum emission limits to prevent interference with authorized radio services.
- ANSI C63.4: American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz. This provides the detailed test procedures and measurement techniques.
- Conducted Emission Limits: Defines maximum allowable electromagnetic interference conducted through power supply lines, typically measured from 150 kHz to 30 MHz.
- Radiated Emission Limits: Specifies maximum electromagnetic field strength at specified distances from the device, typically measured from 30 MHz to several GHz depending on device characteristics.
The testing laboratory applied appropriate decision rules accounting for measurement uncertainty to determine pass/fail status. The S3 inflator pump met all applicable limits with margin, ensuring robust compliance under normal operating conditions and manufacturing variations.

Frequently Asked Questions
What does FCC-SDOC certification mean for the ETENWOLF S3?
FCC-SDOC (Supplier’s Declaration of Conformity) certification means the ETENWOLF S3 tire inflator has been tested and verified to comply with FCC Part 15 electromagnetic emission requirements. This certification is legally required to market and sell the device in the United States, ensuring it does not cause harmful interference to radio communications.
Do I need to keep this certification document with my S3 inflator?
End users do not need to retain the full certification report. However, the product should display FCC compliance information (typically an FCC ID or declaration statement) on its label or in the user manual. The manufacturer maintains the test report as evidence of compliance for regulatory purposes.
How long is the FCC certification valid?
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-SDOC Certification Report for ETENWOLF S3 Cordless Tire Inflator – WTH25H07183671E; 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.
