Document Overview
This article covers the FCC Supplier’s Declaration of Conformity (SDoC) issued for the ETENWOLF Air3 portable air pump. The document was produced by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an accredited compliance testing laboratory, and signed by Tony Wu, General Manager, on June 4, 2025.
The Verification of Conformity (VoC) confirms that the Air3 has been evaluated against the United States Federal Communications Commission (FCC) radio frequency emissions rules, specifically 47 CFR Part 15, Subpart B, and found to be compliant. The scope of this certification covers unintentional radiator requirements applicable to electronic devices marketed and sold in the United States.

| Manufacturer Address | No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R. China |
The Air3 operates on a low-voltage DC input of 5V at 2A, making it compatible with standard USB power sources. This design positions it as a highly portable and travel-friendly inflation tool suitable for tyres, sports equipment, and inflatables.
Key Details
The compliance evaluation was conducted on a single production sample of the Air3. The VoC establishes that the device meets the electromagnetic emissions limits set out under FCC rules for unintentional radiators. Key procedural and regulatory details are summarised below.
| Item | Detail |
|---|---|
| Test Standard | 47 CFR Part 15 Subpart B (October 2020 edition) |
| Measurement Procedure | ANSI C63.4:2014 + Amendment A1:2017 |
| Device Classification | Unintentional Radiator (Part 15 Subpart B) |
| Authorization Type | Supplier’s Declaration of Conformity (SDoC) per FCC Section 2.906 |
| Labeling Requirement | Must comply with Section 15.19(a) labeling requirements |
| FCC Logo Use | Voluntary; permitted only for products fully compliant with SDoC procedures |
| Basis of VoC | Single sample test; does not imply assessment of entire production run |
Under the SDoC framework, the responsible party (Guangdong Bestek Technology Co., LTD) is required to retain the test report and all supporting compliance documentation, and must make these available to the Federal Communications Commission (FCC) upon request before marketing the Air3 in the United States.
Standards & Compliance
The Air3 was tested and found compliant with the following regulatory standards and measurement procedures:
- 47 CFR Part 15, Subpart B (October 2020) — FCC rules governing unintentional radiators. This subpart establishes the technical standards for controlling radio frequency interference generated by electronic and electrical equipment.
- ANSI C63.4:2014 + A1:2017 — 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 is the accepted measurement procedure referenced by the FCC for SDoC compliance testing.
Compliance with 47 CFR Part 15 Subpart B means the Air3 does not exceed the permissible limits for conducted and radiated emissions that could cause harmful interference to radio communications. The FCC SDoC pathway (as defined under Section 2.906) requires the responsible party to self-declare conformity based on verified test data, rather than submitting to a third-party Certification process, though the test must still be performed by a competent laboratory.
Labeling of the Air3 must satisfy the requirements of FCC Section 15.19(a). Voluntary use of the FCC logo on the product is permitted provided full SDoC procedural compliance is maintained.

| Validity Note | Based on single sample test; does not cover full production assessment |
It is important to note that as per standard SDoC practice, this VoC is based on testing of a single representative sample of the Air3. The responsible party — Guangdong Bestek Technology Co., LTD — bears ongoing responsibility for ensuring that production units continue to conform to the tested standards, and must be able to produce supporting documentation at the FCC’s request.
Frequently Asked Questions
- What does the FCC SDoC mean for the ETENWOLF Air3?
-
The FCC Supplier’s Declaration of Conformity (SDoC) means that the Air3 has been tested and confirmed to comply with 47 CFR Part 15 Subpart B, the FCC’s rules for unintentional radio frequency emitters. It authorises the Air3 to be legally marketed and sold in the United States, provided the responsible party retains the test documentation and makes it available to the FCC upon request.
- Which test standard was used to certify the Air3?
-
The Air3 was tested according to 47 CFR Part 15 Subpart B (October 2020), using the measurement procedure defined in ANSI C63.4:2014 + Amendment A1:2017. Both references govern radio frequency emissions testing for low-voltage electronic equipment sold in the United States.
- Does the FCC SDoC cover all units produced, or just the tested sample?
-
The VoC (Reference No. WTH25H05129164E) is based on a single sample test of the Air3. It does not constitute an assessment of the entire production run. The manufacturer, Guangdong Bestek Technology Co., LTD, is responsible for ensuring ongoing production compliance and retaining all supporting test data for FCC inspection.
- Can the FCC logo be placed on the Air3 product?
-
Use of the FCC logo is voluntary under the SDoC framework. It may only be applied to the Air3 if the product fully complies with all SDoC procedures, and the labeling must additionally meet the requirements of FCC Section 15.19(a). Misuse of the FCC logo on non-compliant products is prohibited.
