The issuing laboratory confirms that the referred test reports demonstrate the product meets standards recognized as giving presumption of conformity with the essential requirements of EMC Directive 2014/30/EU. Following preparation of the required technical documentation and EU Declaration of Conformity, the CE marking may be affixed to the product under the sole responsibility of the manufacturer.
Standards & Compliance
The ETENWOLF S1 was tested against the following harmonized European standards. All tests returned compliant results.
| Standard | Full Title | Scope |
|---|---|---|
| EN IEC 55014-1: 2021 | Electromagnetic compatibility – Requirements for household appliances, electric tools and similar apparatus – Part 1: Emission (CISPR 14-1:2016 + COR1:2016) | Radiated and conducted electromagnetic emissions |
| EN IEC 55014-2: 2021 | Electromagnetic compatibility – Requirements for household appliances, electric tools and similar apparatus – Part 2: Immunity – Product family standard (CISPR 14-2:2015) | Immunity to electromagnetic disturbances |
| EN IEC 61000-3-2: 2019+A1:2021 | Electromagnetic compatibility (EMC) – Part 3-2: Limits – Limits for harmonic current emissions (equipment input current ≤16 A per phase) | Harmonic current emission limits |
| EN 61000-3-3: 2013+A2:2021 | Electromagnetic compatibility (EMC) – Part 3-3: Limits – Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current ≤16 A per phase and not subject to conditional connection | Voltage fluctuation and flicker limits |
These standards collectively ensure that the S1 does not cause harmful electromagnetic interference to other devices and is itself sufficiently immune to electromagnetic disturbances present in typical operating environments within the European Union.
Validity & Certification Body
The certificate was issued on December 25, 2025, and is valid as long as the product design, components, and manufacturing processes remain unchanged from those evaluated during testing. Any modifications to the product may require re-testing and re-certification.

Frequently Asked Questions
- What does the CE-EMC certificate for the ETENWOLF S1 mean for consumers?
-
The CE-EMC certificate (Ref. WTH25H12333145E) confirms that the ETENWOLF S1 has been tested and found compliant with the European EMC Directive 2014/30/EU. This means the device does not produce electromagnetic interference that could disrupt other electronics, and it can withstand electromagnetic disturbances in normal usage environments. EU consumers can use the product with confidence that it meets mandatory regulatory requirements.
- Which specific EMC standards were tested for the S1 tire inflator?
-
The S1 was evaluated against four harmonized standards: EN IEC 55014-1:2021 (emissions), EN IEC 55014-2:2021 (immunity), EN IEC 61000-3-2:2019+A1:2021 (harmonic current emissions), and EN 61000-3-3:2013+A2:2021 (voltage fluctuation and flicker). The product passed all four tests.
- What is the rated electrical input of the ETENWOLF S1?
-
The S1 operates on a rated input of DC 5V at 2A. This low-voltage DC input makes it compatible with standard USB power sources, which is consistent with its design as a portable, rechargeable inflation tool.
- Does this CE-EMC certificate cover the full production run of the S1?
-
No. As stated in the certification document, the assessment is based on one or several specimens of the product. It does not imply conformity assessment of the entire production. The manufacturer, Guangdong Bestek Technology Co., LTD, bears sole responsibility for ensuring ongoing production conformity and must maintain the EU Declaration of Conformity and technical documentation.
