Product Information
The Equipment Under Test (EUT) evaluated in report WTH25H09239214E is the ETENWOLF C2 Wireless Portable Tire Pump, a battery-powered cordless inflation tool designed for inflating vehicle tires and other inflatables without requiring a mains power connection during operation.
| Field | Detail |
|---|---|
| Product Name | Wireless Portable Tire Pump |
| Model Number | C2 |
| Brand | ETENWOLF |
| Applicant | 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 |
As a portable, motor-driven electrical appliance, the C2 falls under the product category addressed by the household and similar electrical appliances EMC standard series, requiring assessment of both conducted and radiated electromagnetic emissions to ensure it does not interfere with other equipment operating in its environment.
Key Details
The test report WTH25H09239214E covers a comprehensive set of EMC emission measurements conducted across three primary test categories. All measurements were performed with the EUT in its intended operational mode simulating active tire inflation. The following table summarises the test areas covered and their outcomes.
| Test Category | Section | Standard Applied | Result |
|---|---|---|---|
| Conducted Disturbance at Mains Terminals | Section 3 | EN IEC 55014-1: 2021 | Pass |
| Disturbance Power in the Frequency Range | Section 4 | EN IEC 55014-1: 2021 | Pass |
| Radiated Disturbances | Section 5 | EN IEC 55014-1: 2021 | Pass |
| Harmonics Current Emissions | Referenced | EN IEC 61000-3-2: 2019+A1:2021 | Pass |
| Voltage Fluctuations and Flicker | Referenced | EN 61000-3-3: 2013+A2:2021 | Pass |
The test configuration included justification documentation, EUT exercise procedures, equipment modification records, basic system configuration descriptions, general descriptions of test auxiliaries, and application of the laboratory’s decision rule — all detailed across sections 2.1 through 2.6 of the full 51-page report. Measurement uncertainty budgets were documented for each test category in accordance with laboratory quality requirements.
Tests were carried out between 2025-09-08 and 2025-09-10 at the HCT Shenzhen facility. The report was prepared by Snow Zeng and approved by Tony Wu of Waltek Testing Group HCT (Shenzhen) Co., Ltd.
Standards & Compliance
The ETENWOLF C2 was evaluated against the following European harmonised standards. Compliance with these standards supports the CE marking declaration for the EMC Directive 2014/30/EU.
| Standard | Title | Scope |
|---|---|---|
| EN IEC 55014-1: 2021 | Electromagnetic Compatibility — Requirements for Household Appliances, Electric Tools and Similar Apparatus — Part 1: Emission | Conducted and radiated emission limits for motor-operated and switching devices |
| EN IEC 55014-2: 2021 | Electromagnetic Compatibility — Requirements for Household Appliances, Electric Tools and Similar Apparatus — Part 2: Immunity | Immunity requirements for the same product category |
| EN IEC 61000-3-2: 2019+A1:2021 | Electromagnetic Compatibility — Limits for Harmonic Current Emissions | Harmonic current emissions for equipment with input current up to and including 16 A per phase |
| EN 61000-3-3: 2013+A2:2021 | Electromagnetic Compatibility — Limitation of Voltage Changes, Voltage Fluctuations and Flicker | Voltage fluctuation and flicker limits for equipment with rated current up to and including 16 A |
The test report form used was TRF EN IEC 55014-1: 2021-EMC-001-V01, which is the standardised reporting template aligned with the EN IEC 55014-1: 2021 test methodology. The laboratory’s decision rule for determining pass/fail against measurement uncertainty was applied as documented in Section 2.6 of the report.

Frequently Asked Questions
- What does the CE-EMC test report WTH25H09239214E confirm about the ETENWOLF C2?
-
Report WTH25H09239214E confirms that the ETENWOLF C2 Wireless Portable Tire Pump passed all electromagnetic compatibility emission tests required for CE marking under the EMC Directive 2014/30/EU. Tests covered conducted disturbances at mains terminals, disturbance power, radiated disturbances, harmonic current emissions, and voltage fluctuation/flicker — all evaluated against the applicable EN IEC 55014-1: 2021, EN IEC 55014-2: 2021, EN IEC 61000-3-2: 2019+A1:2021, and EN 61000-3-3: 2013+A2:2021 standards.
- Which standards were used to test the ETENWOLF C2 for CE-EMC compliance?
-
The C2 was tested against four harmonised European standards: EN IEC 55014-1: 2021 and EN IEC 55014-2: 2021 (emission and immunity requirements for household appliances and electric tools), EN IEC 61000-3-2: 2019+A1:2021 (harmonic current emissions), and EN 61000-3-3: 2013+A2:2021 (voltage fluctuations and flicker). These standards are harmonised under the EU EMC Directive 2014/30/EU.
- Who conducted the CE-EMC testing for the ETENWOLF C2?
-
The testing was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an EMC testing laboratory based in Longgang District, Shenzhen, China. The report was prepared by Snow Zeng and approved by Tony Wu. Testing took place from 2025-09-08 to 2025-09-10, and the report was issued on 2025-09-15.
- Does the CE-EMC pass mean the ETENWOLF C2 is safe to sell in Europe?
-
A passing CE-EMC test report is a key component of the CE marking process, demonstrating that the C2 meets electromagnetic compatibility requirements for the European market. However, full CE marking may also require compliance with other applicable directives (such as the Low Voltage Directive or Machinery Directive depending on the product classification) and a complete Declaration of Conformity from the manufacturer. The EMC report alone covers the electromagnetic emissions and immunity aspect.
