Key Details
The certification is based on testing of one or several specimens of the Helios J1 against all applicable EMC standards. The table below summarises the key certification findings and test outcomes.
| Standard | Scope | Result |
|---|---|---|
| EN IEC 55014-1: 2021 | EMC – Emission requirements for household appliances, electric tools and similar apparatus (CISPR 14-1:2016 + COR1:2016) | Compliant |
| EN IEC 55014-2: 2021 | EMC – Immunity product family standard for household appliances, electric tools and similar apparatus (CISPR 14-2:2015) | Compliant |
| EN IEC 61000-3-2: 2019+A1:2021 | EMC – Limits for harmonic current emissions (input current ≤16 A per phase) | Compliant |
| EN 61000-3-3: 2013+A2:2021 | EMC – Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems (rated current ≤16 A per phase) | Compliant |
The test reports demonstrate that the Helios J1 meets all essential EMC requirements prescribed by the applicable EU harmonisation legislation. Upon preparation of the required technical documentation and EU Declaration of Conformity, the CE marking may be affixed by the manufacturer.
Standards & Compliance
The Helios J1 was evaluated against four harmonised European EMC standards, each addressing a distinct aspect of electromagnetic performance. Compliance with these standards provides a presumption of conformity with the essential requirements of Directive 2014/30/EU.
- EN IEC 55014-1: 2021 — Addresses conducted and radiated electromagnetic emissions from household appliances, electric tools and similar apparatus. Based on international standard CISPR 14-1:2016 including Corrigendum 1:2016.
- EN IEC 55014-2: 2021 — Specifies immunity requirements for the same product family, ensuring the device maintains proper operation when exposed to external electromagnetic disturbances. Based on CISPR 14-2:2015.
- EN IEC 61000-3-2: 2019+A1:2021 — Sets limits for harmonic current emissions injected into the public supply network by equipment with an input current of 16 A or less per phase.
- EN 61000-3-3: 2013+A2:2021 — Limits voltage changes, fluctuations and flicker caused by equipment connected to public low-voltage supply systems, applicable to devices with a rated current of 16 A or less per phase that are not subject to conditional connection.
Collectively, these standards ensure that the Helios J1 neither causes harmful electromagnetic interference to other devices nor is susceptible to electromagnetic disturbances that would degrade its own performance.
Validity & Certification Body
This certificate was issued on September 23, 2025. No explicit expiry date is stated in the document; however, CE-EMC certificates are subject to review whenever the product design, components, or applicable harmonised standards are materially changed. The manufacturer, Guangdong Bestek Technology Co., Ltd., bears sole responsibility for maintaining conformity and for affixing the CE marking after completing the required EU Declaration of Conformity and technical documentation.

Frequently Asked Questions
- What does CE-EMC certification mean for the Helios J1?
-
CE-EMC certification confirms that the Helios J1 has been independently tested and found compliant with European Directive 2014/30/EU. This means the device meets strict limits for electromagnetic emissions and is immune to electromagnetic disturbances at levels that would impair its operation. It is a legal prerequisite for selling the product within the European Economic Area.
- Which test standards were applied to the Helios J1?
-
Four harmonised standards were applied: EN IEC 55014-1: 2021 (emissions), EN IEC 55014-2: 2021 (immunity), EN IEC 61000-3-2: 2019+A1:2021 (harmonic current limits), and EN 61000-3-3: 2013+A2:2021 (voltage fluctuation and flicker limits). All tests were conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd.
- What are the charging and output capabilities of the Helios J1?
-
The Helios J1 features a USB Type-C port that supports both input and output at DC 5V/3A, 9V/3A, 12V/2.5A, 15V/2A, and 20V/1.5A, covering the full USB Power Delivery range. The USB-A (USB1) output supports DC 5V/3A, 9V/2A, and 12V/1.5A for quick charging of mobile devices.
- Does this certificate cover all units of the Helios J1 in production?
-
No. As stated in the certificate, the evaluation is based on one or several product specimens and does not imply an assessment of the whole production. The manufacturer, Guangdong Bestek Technology Co., Ltd., is solely responsible for ensuring that all production units continuously conform to the tested standards and for completing the EU Declaration of Conformity before applying the CE mark.
