OneKey Pro Wallet Passes IEC 62133-2 International Battery Safety Certification

In the field of portable electronic devices, battery safety is not only about product longevity but also directly related to user safety. Recently, the core energy component of the OneKey Pro Wallet—a 900mAh rechargeable Li-ion battery—officially passed the IEC 62133-2:2017 Safety Standard Certification established by the International Electrotechnical Commission (IEC).

This authoritative test report, numbered PNS220930306 02001, was issued by Guangdong UTL Co., Ltd. on October 26, 2022. It marks that the battery system of the OneKey Pro complies with the world's most rigorous safety specifications, meeting the access requirements for high-end markets such as Europe and America.

Part 1: What is this certification and what is its core significance?

IEC 62133 is the most universal international safety standard for portable sealed secondary cells (containing alkaline or other non-acid electrolytes). Specifically, Part 2 (IEC 62133-2) focuses on Lithium systems. It is currently recognized as the "Gold Standard for Battery Safety" in the global consumer electronics industry and is the core basis for entering the CB Scheme (IECEE).

1. Eliminating "Thermal Runaway" Hazards

If designed improperly, lithium batteries are prone to thermal runaway during overcharging, short circuits, or heating. Passing the IEC 62133-2 certification means that the OneKey Pro battery incorporates multiple protection mechanisms (such as overcharge protection ICs, MOSFET fusing, etc.) right from the design source, fundamentally eliminating the risks of spontaneous combustion and explosion.

2. The "Master Key" for Global Market Access

IEC 62133 reports are typically used to transfer CB certifications, which are then recognized by multiple countries and regions, including Europe (CE), Korea (KC), and Japan (PSE). Obtaining this certification for OneKey Pro is equivalent to holding a "master key" to the global market, proving that its hardware quality can withstand inspections by various regulatory bodies worldwide.

Part 2: What requirements must be met to pass this certification?

To obtain this certificate, the battery component of the OneKey Pro (Model: PoweRally 452265) had to pass a series of tests simulating extreme abuse scenarios. According to the detailed records in the report, the battery performed exceptionally well in the following key items:

1. Electrical Safety and Protection Circuit Tests

• Continuous Charging at Constant Voltage (7.2.1): Simulating continuous charging for 7 days while fully charged. Results showed no leakage, fire, or explosion, proving the battery is safe even when left connected to a charger for extended periods.
• External Short Circuit (7.3.1 & 7.3.2): Artificially short-circuiting the battery terminals at ambient and high temperatures (55°C). The OneKey Pro battery quickly cut off the circuit at the moment of the short circuit and remained effective even under "Single Fault" conditions, avoiding thermal runaway.
• Over-charging (7.3.6): Simulating a charger malfunction outputting high voltage. The internal protection mechanism successfully activated when the battery was subjected to excessive voltage and current surges, preventing danger.

2. Mechanical Strength and Physical Tolerance Tests

• Free Fall (7.3.3): Simulating accidental drops during daily use. The battery was dropped from a height of 1 meter onto concrete, 3 times per side, totaling 18 drops. Post-test, the battery structure remained intact with no fire or explosion.
• Crush (7.3.5): The battery withstood a crushing force of up to 13kN. Even with casing deformation, the internal components remained stable, avoiding internal short circuits that could lead to fire.
• Vibration & Mechanical Shock (7.3.8): Simulating severe bumps during transport, the battery passed the tests, proving its structural design is robust and reliable.

3. Environmental Adaptability Tests

• Thermal Abuse (7.3.4): The battery was placed in a high-temperature oven at 130°C for 30 minutes. This is a highly challenging test designed to verify the thermal stability of the battery separator. The OneKey Pro battery passed successfully, demonstrating extremely high heat resistance.

Part 3: Future Outlook

OneKey Pro's passing of the IEC 62133-2 certification is strong evidence of OneKey's adherence to the "Safety First" product philosophy.

1. Strict Supply Chain Selection, Transparent Quality

The report details the Critical Components List of the battery, including protection ICs (NEOTEC), MOSFETs, and electrolyte suppliers from well-known manufacturers. OneKey spares no expense in selecting raw materials that have passed international certifications like UL, ensuring that every battery is a premium product.

2. Safeguarding High-Frequency Usage Scenarios

As a flagship device with a large touch screen, the OneKey Pro is often used more frequently than ordinary cold wallets. The IEC 62133-2 certification not only guarantees storage safety but also ensures user safety during high-frequency charging and daily carrying.

OneKey is redefining the quality benchmark for Web3 hardware with a series of hardcore international certifications—safety lies not only in preventing hacking but also in preventing accidents.
