Document Overview
This article covers the Supplier’s Declaration of Conformity (SDoC) issued under FCC Reference Number WTH25H07201499E (Registration No. WTH25H07201499). The document was issued by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an accredited third-party test laboratory, and signed by General Manager Tony Wu on August 6, 2025.
The SDoC confirms that the product has been evaluated against 47 CFR Part 15, Subpart B of the Federal Communications Commission (FCC) Rules and Regulations, which governs unintentional radiators and electromagnetic interference (EMI) limits applicable to electronic devices marketed in the United States.
Under Section 2.906 of the FCC rules, the responsible party (applicant/holder) is required to maintain the test report and all supporting compliance documentation and must provide these upon request by the FCC prior to or during marketing of the device in the USA.
Product Information
The certified product is the HB2, a compact electric inflation pump marketed under the ETENWOLF brand. Below are the key product details as recorded in the certificate:
| Field | Details |
|---|---|
| Product Name | PUMP 2 |
| Model Number | HB2 |
| Trade Mark | N/A |
| Rated Input | DC 5V |
| Applicant / Holder | Guangdong Bestek Technology Co., LTD |
| Manufacturer | Guangdong Bestek Technology Co., LTD |
| Manufacturer Address | No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R. China |
The HB2 operates on a DC 5V input, making it compatible with standard USB power sources. Its compact design positions it as a portable inflation solution for everyday use.
Key Details
The following table summarizes the critical certification details extracted directly from the FCC SDoC document:
| Parameter | Value |
|---|---|
| Certificate / Reference No. | WTH25H07201499E |
| Registration No. | WTH25H07201499 |
| Document Type | Verification of Conformity (VoC) / FCC SDoC |
| Applicable Regulation | 47 CFR Part 15, Subpart B (October 2020 edition) |
| Measurement Procedure | ANSI C63.4:2014 + A1:2017 |
| Labeling Requirement | Section 15.19(a) — FCC label required; FCC logo optional if fully compliant with SDoC procedures |
| Compliance Pathway | Supplier’s Declaration of Conformity (SDoC) per Section 2.906 |
| Issue Date | August 6, 2025 |
| Signed By | Tony Wu, General Manager, Waltek Testing Group HCT (Shenzhen) Co., Ltd. |
The VoC is based on a single-sample test of the HB2 and does not constitute an assessment of the entire production batch. The responsible party must ensure ongoing production compliance independently.
Standards & Compliance
The HB2 was tested and found compliant with the following regulatory standards and measurement procedures:
- 47 CFR Part 15, Subpart B (October 2020) — FCC rules for unintentional radiators, governing conducted and radiated emissions limits for digital devices sold in the United States.
- ANSI C63.4:2014 + A1:2017 — American National Standard methods of measurement of radio-noise emissions from low-voltage electrical and electronic equipment in the range 9 kHz to 40 GHz. This is the accepted measurement procedure under FCC rules.
- FCC Section 15.19(a) — Labeling requirements mandating that the device carry the appropriate FCC compliance statement or label prior to marketing.
- FCC Section 2.906 — Defines the SDoC authorization procedure, under which the responsible party declares conformity and retains test documentation available upon FCC request.
The SDoC pathway applies to Class B digital devices intended for use in a residential environment, ensuring they do not cause harmful interference to radio communications. The optional FCC logo may be applied to the product label only when full SDoC procedural compliance is maintained.

Regarding validity: FCC SDoC certificates do not carry a fixed expiration date. However, the declaration remains valid only as long as the product continues to be manufactured without changes that could affect its compliance characteristics. If the design, components, or circuitry of the HB2 are modified, re-testing and re-declaration may be required. The FCC retains the right to request supporting test documentation at any time, and the responsible party — Guangdong Bestek Technology Co., LTD — must be able to produce it promptly.
Frequently Asked Questions
- Q: What does the FCC SDoC mean for the HB2 pump?
- The FCC Supplier’s Declaration of Conformity (SDoC) means the HB2 has been tested and found to comply with 47 CFR Part 15 Subpart B, confirming it does not generate electromagnetic interference beyond the limits permitted for devices marketed and sold in the United States.
- Q: Is the FCC SDoC the same as an FCC ID?
- No. An FCC ID is required for intentional radiators (devices that deliberately emit radio frequency energy, such as Wi-Fi or Bluetooth products) and involves third-party certification. The SDoC pathway applies to unintentional radiators like the HB2, where the responsible party self-declares conformity based on test results from an accredited laboratory.
- Q: What standards were used to test the HB2?
- The HB2 was tested to 47 CFR Part 15 Subpart B (October 2020) using the measurement procedures defined in ANSI C63.4:2014 + A1:2017. Testing was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd.
- Q: Does this certificate cover all units of the HB2 produced?
- The VoC is based on a single-sample test as stated in the document. It does not represent an assessment of the full production run. The responsible party, Guangdong Bestek Technology Co., LTD, is obligated to ensure that all manufactured units of the HB2 conform to the same design and comply with FCC rules.
