The scope of this report covers electromagnetic emissions testing — including conducted disturbances at mains terminals, disturbance power in the frequency range, and radiated disturbances — as required under the applicable CE marking directives for portable power equipment sold in the European Economic Area.
Product Information
The equipment under test (EUT) is the Helios J1, a portable automotive jump starter designed to provide emergency starting power for vehicles without requiring a secondary vehicle or external power source.
| Field | Detail |
|---|---|
| Product Name | Portable Automotive Jump Starter |
| Model Number | Helios J1 |
| 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 |
| Product Category | Portable automotive starting and power supply equipment |
The Helios J1 is a battery-powered, handheld device intended for use in automotive environments. As a portable electronic product containing internal lithium battery cells and power electronics, it is subject to electromagnetic emissions requirements to ensure it does not cause harmful interference to other equipment or radio communications.
Key Details
The test report covers four primary EMC test categories as defined by the applicable standards. The following table summarises the test areas, the corresponding standard clauses, and the outcome of each evaluation.
| Test Category | Standard Reference | Report Section | Result |
|---|---|---|---|
| Conducted Disturbance at Mains Terminals | EN IEC 55014-1: 2021 | Section 3 | Pass |
| Disturbance Power in Frequency Range | EN IEC 55014-1: 2021 | Section 4 | Pass |
| Radiated Disturbances | EN IEC 55014-1: 2021 | Section 5 | Pass |
| Immunity (General) | EN IEC 55014-2: 2021 | Sections 6+ | Pass |
Additional supporting measurements were carried out in accordance with EN IEC 61000-3-2:2019+A1:2021 (harmonic current emissions) and EN 61000-3-3:2013+A2:2021 (voltage fluctuations and flicker). The full 56-page report documents detailed measurement uncertainty budgets, EUT configuration, instrument setup, and tabulated test data for each section.
The test system configuration included justification documentation, EUT exercise software details, equipment modification records, basic test system configuration, general description of test auxiliaries, and a defined decision rule applied consistently throughout testing.
Standards & Compliance
The Helios J1 was evaluated against the following European harmonised standards as required for CE marking under the Radio Equipment Directive (RED) and Electromagnetic Compatibility Directive (2014/30/EU).
| Standard | Title / Scope | Edition Applied |
|---|---|---|
| EN IEC 55014-1: 2021 | Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 1: Emission | 2021 |
| EN IEC 55014-2: 2021 | Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 2: Immunity | 2021 |
| EN IEC 61000-3-2:2019+A1:2021 | Electromagnetic compatibility — Limits for harmonic current emissions (equipment input current ≤16 A per phase) | 2019 + Amendment 1:2021 |
| EN 61000-3-3:2013+A2:2021 | Electromagnetic compatibility — Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems | 2013 + Amendment 2:2021 |
All test methods were applied using the test report form TRF EN IEC 55014-1: 2021-EMC-001-V01. Measurement uncertainty was documented per section and applied in accordance with the laboratory’s accreditation requirements. A formal decision rule was applied to all pass/fail determinations, consistent with ILAC guidelines on measurement uncertainty.

The report is valid for CE marking purposes for the exact model and configuration described herein.
Frequently Asked Questions
- What does CE-EMC certification mean for the Helios J1?
-
CE-EMC certification confirms that the Helios J1 meets the electromagnetic compatibility requirements of the European Union’s EMC Directive (2014/30/EU). This means the device does not emit electromagnetic interference beyond permitted limits and is sufficiently immune to interference from other equipment — making it safe and legal to sell throughout the European Economic Area.
- Which specific standards were used to test the Helios J1?
-
The Helios J1 was tested against four harmonised standards: EN IEC 55014-1:2021 (emissions), EN IEC 55014-2:2021 (immunity), EN IEC 61000-3-2:2019+A1:2021 (harmonic currents), and EN 61000-3-3:2013+A2:2021 (voltage fluctuations and flicker). All tests returned a Pass result.
- Who issued the test report and is the laboratory accredited?
-
The report reference WTH25H06163591R1E was issued by Waltek Testing Group HCT (Shenzhen) Co., Ltd., a professional EMC and safety testing laboratory based in Shenzhen, China. Waltek Testing Group operates accredited facilities that support CE, FCC, KC, and other international certification programmes. The report was prepared by Snow Zeng and approved by Tony Wu.
- Does this report cover both emissions and immunity testing?
-
Yes. The report covers emissions testing under EN IEC 55014-1:2021 — including conducted disturbances at mains terminals, disturbance power measurements, and radiated disturbances — as well as immunity testing under EN IEC 55014-2:2021. Both aspects are required for a complete CE-EMC declaration of conformity for the Helios J1.
