Standards & Compliance
The ETENWOLF C2 was evaluated against the following regulatory standards and measurement procedures:
- 47 CFR Part 15, Subpart B (October 2020) – FCC Rules for unintentional radiators. This subpart sets limits on radio frequency emissions from digital devices to prevent harmful interference with licensed radio services.
- 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 measurement procedure referenced by the FCC for Subpart B compliance.
- FCC Section 15.19(a) – Labeling requirements mandating that the device bear the appropriate FCC compliance statement or logo.
- FCC Section 2.906 – Governs the Supplier’s Declaration of Conformity process, which must be completed before the product is placed on the US market.
Compliance with these standards ensures the C2 does not emit radio frequency energy that could interfere with other electronic equipment or licensed radio communications.

Frequently Asked Questions
- What does FCC Part 15 Subpart B certification mean for the ETENWOLF C2?
-
It means the C2 Wireless Portable Tire Pump has been tested and found to comply with the FCC’s limits on unintentional radio frequency emissions. This certification is required for any digital electronic device sold in the United States and confirms that the pump will not cause harmful interference to other electronic equipment or licensed radio services.
- What is the difference between the Registration No. and the Reference No. on this certificate?
-
The Registration No. (WTH25H09239219) identifies the test project file within Waltek HCT’s internal system. The Reference No. (WTH25H09239219E) is the specific certificate reference used for the FCC Verification of Conformity document. Both numbers uniquely identify the same certification engagement for the C2.
- Is the FCC logo required on the ETENWOLF C2 product?
-
Use of the FCC logo on SDoC-authorized devices is voluntary, not mandatory. However, if the FCC logo is applied to the C2, the product must be fully compliant with all SDoC procedures as outlined in FCC rules. The device label must comply with the requirements of Section 15.19(a) regardless of whether the logo is used.
- Does this certificate cover all units of the C2 produced?
-
No. As stated in the VoC, testing was conducted on a single sample of the C2. The certificate does not imply an assessment of the entire production run. The responsible party (Guangdong Bestek Technology Co., LTD) is accountable for ensuring that all manufactured units conform to the same design and specifications as the tested sample.
