| Test Basis | Single sample test; does not imply assessment of entire production |
The VoC is issued with the reservation that the responsible party (Guangdong Bestek Technology Co., LTD) must provide the test report and all supporting compliance documentation to the Federal Communications Commission (FCC) upon request.
Standards & Compliance
The ETENWOLF V3 air inflator was evaluated against the following regulatory standards and measurement procedures to confirm electromagnetic compatibility (EMC) compliance before being marketed in the United States.
- 47 CFR Part 15 Subpart B (October 2020) — FCC regulations governing unintentional radiators and their radiated/conducted emissions limits.
- ANSI C63.4:2014 + A1:2017 — Standard measurement procedures for determining compliance of low-voltage electrical and electronic equipment with FCC Part 15 emissions limits.
- FCC Section 2.906 — Defines the Supplier’s Declaration of Conformity authorization pathway applicable to this device category.
- FCC Section 15.19(a) — Labeling requirements for devices subject to Part 15 authorization.
As an unintentional radiator operating at DC 12V input, the V3 falls under the SDoC authorization route, which allows the responsible party to self-declare conformity based on a test report from an accredited laboratory, without requiring FCC pre-market approval.

Frequently Asked Questions
- What is an FCC SDoC and how does it differ from FCC ID certification?
-
An FCC Supplier’s Declaration of Conformity (SDoC) is a self-declaration pathway where the responsible party (manufacturer or importer) confirms that a device complies with FCC Part 15 Subpart B emissions limits, based on testing by an accredited lab. Unlike FCC ID certification, SDoC does not require pre-market FCC approval or a unique FCC ID number. It applies to unintentional radiators such as the ETENWOLF V3 air inflator.
- Is the ETENWOLF V3 air inflator legal to sell in the United States?
-
Yes. The ETENWOLF V3 has been tested and found compliant with 47 CFR Part 15 Subpart B as documented in VoC reference WTH25H05129147E. The responsible party may issue an SDoC per FCC Section 2.906 and legally market the device in the USA, provided all labeling requirements under Section 15.19(a) are met.
- What does the VoC test cover and what are its limitations?
-
The VoC is based on testing a single production sample of the ETENWOLF V3. It verifies that the sample meets FCC Part 15 Subpart B radiated and conducted emissions limits using ANSI C63.4:2014+A1:2017 measurement procedures. It does not imply conformity of the entire production batch. The responsible party must ensure ongoing production quality and retain test documentation for FCC inspection upon request.
- Can the FCC logo be placed on the ETENWOLF V3 product?
-
Use of the FCC logo is voluntary for SDoC-authorized devices. It may be placed on the ETENWOLF V3 only if the product fully complies with all SDoC procedures as defined by the FCC. The mandatory requirement is compliance with the labeling provisions of Section 15.19(a), not the presence of the FCC logo itself.
