Amazon Power Bank IEC 62368 Test Report

Current Status of Power Bank Development

The development of power banks shows characteristics of increased battery capacity, REDuced size, and improved safety. Initially, power banks were bULky with limited capacity. However, advancements in battery technology, especially lithium-ion batteries, have made them smaller and higher in capacity. Additionally, the integration of smart power management systems and the application of technologies such as Gallium Nitride (GaN) chargers and USB-C have improved efficiency and compatibility.

Faster Charging Speed

The adoption of technologies such as GaN chargers and Power Delivery (PD) has significantly increased charging speeds for both power banks and connected devices.

Enhanced Compatibility

Universal USB-C interfaces and compatibility with proprietary smartphone charging protocols such as Qualcomm Quick Charge have expanded the range of devices that power banks can charge.

IEC 62368 Requirement for International Sales of Power Banks

To sell power banks globally, IEC 62368-1 standard testing reports or cb certification is required. Today, we introduce the testing items, costs, and process for obtaining the IEC 62368-1 standard testing report.

Introduction to IEC 62368

IEC stands for the International Electrotechnical Commission, an organization that develops globally recognized standards for electrical, electronic, and related technologies, collectively referred to as "electrotechnology."

Overview of IEC 62368 Standard

The IEC 62368 standard applies to electrical and electronic information equipment in the fields of audio, video, information, communication technology, business, and office machines with rated voltages not exceeding 600V. It is a new product safety concept based on hazard-based safety engineering principles, designed to protect users and their environments from harm such as electric shock, fire, electromagnetic fields, and other hazardous energy. IEC 62368 encompasses the previous IEC 60065 and IEC 60950 standards and will gradually replace them.

Process for Obtaining an IEC 62368 Report

Process:

1. Fill out the quality inspection report application form.

2. Ship samples to the laboratory.

3. Test samples; if not compliant, notify the company to modify the samples.

4. Upon passing, JJR Laboratory issues the test report.

Required Documents:

1. Product specifications and user manual.

2. Design drawings and circuit diagrams.

3. Battery parameters and iec 62133 compliance.

4. Information about charging and discharging protection circuits.

Timeline:5–7 working days.

Note: Testing costs may vary between products and need to be verified by a consultant.
