How to get an IEC 62368 Test Report for Power Banks?

Overview of Power Bank Development

The development of power banks is characterized by increased battery capacity, REDuced size, and enhanced safety. Initially, power banks were bULky with limited capacity. However, advancements in battery technology—especially lithium-ion batteries—have enabled higher capacity in smaller sizes. Moreover, the integration of smart power management systems and the adoption of technologies such as GaN chargers and USB-C have significantly improved efficiency and compatibility.

Faster Charging Speeds

Technologies like Gallium Nitride (GaN) chargers and Power Delivery (PD) have enhanced charging speeds for both the power bank and connected devices.

Enhanced Compatibility

The universal USB-C interface and support for proprietary charging protocols like Qualcomm Quick Charge have expanded the range of devices that power banks can charge.

Introduction to IEC 62368

What is IEC?

IEC stands for the International Electrotechnical Commission, an organization that develops globally recognized standards for electrical, electronic, and related technologies.

About IEC 62368 Standard

IEC 62368 is a safety standard for audio/video, information and communication technology equipment, and office machines operating at voltages not exceeding 600V. This standard introduces a new safety engineering concept based on hazard-based safety principles to protect users and the environment from potential harm such as electric shock, fire, electromagnetic fields, and other hazardous energy. It integrates and gradually replaces the older IEC 60065 and IEC 60950 standards.

Process for Obtaining an IEC 62368 Test Report

Application Process:

1. Fill out the product quality inspection test application form.

2. Send samples to China’s JJR Laboratory.

3. Sample testing. If non-compliant, the lab will notify the company to revise the sample.

4. Once the sample passes, the lab issues the test report.

Required Documents:

- Product specifications and user manual.

- Design and circuit schematics.

- Battery parameters and iec 62133 compliance.

- Information on charging/discharging protection circuits.

Duration:

- Standard processing time is 5–7 working days.

Fees:

- Due to product variation, testing fees must be evaluated and confirmed by a consultant.
