OneKey Classic Wallet Passes US DOE Federal Energy Efficiency Certification

While pursuing ultimate security, OneKey is equally committed to creating eco-friendly and energy-efficient high-quality hardware products. Recently, OneKey's classic hardware wallet—OneKey Classic (Model: BixinKey ONE)—officially passed the federal energy efficiency tests of the U.S. Department of Energy (DOE).

This test report, numbered RKSA200618001-SF-02, was issued by Bay Area Compliance Laboratories Corp. (BACL) on July 9, 2020. It marks that the OneKey Classic not only meets California's strict environmental standards but also fully complies with the mandatory energy efficiency requirements for battery charging systems under U.S. federal law (10 CFR 430).

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

DOE Certification is a mandatory energy efficiency certification implemented by the U.S. federal government for electronic products. According to federal regulation 10 CFR 430.32(z), all consumer electronic products with battery charging systems must be tested by an authorized laboratory to prove their energy efficiency metrics meet federal standards before they can be legally sold throughout the United States.

1. A Nationwide "Badge of Energy Saving"

If CEC is the passport for California, then DOE is the "Badge of Energy Saving" at the federal level. By passing this certification, OneKey Classic proves the efficiency of its power management system. Whether in New York, Texas, or any other state in the US, it is a compliant and green electronic product.

2. A Commitment to Refusing Energy Waste

For a device like the OneKey Classic that needs to be stored for long periods and charged occasionally, standby power consumption is crucial. DOE certification not only focuses on efficiency during charging but also strictly limits energy waste when the device is "idle." Passing this certification means that the OneKey Classic possesses excellent power management logic, minimizing power loss to the greatest extent, saving every cent of electricity for users, and reducing the burden on the planet.

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

DOE tests involve complex calculation formulas and strict limits for "Battery Charger Systems (BCS)." According to the actual measurement data disclosed in the report, the OneKey Classic performed exceptionally well in the following key metrics:

1. Annual Energy Consumption (UEC) Far Below Regulatory Limits

The test report shows that the Unit Energy Consumption (UEC) of the OneKey Classic is only 1.26 kWh/yr.

• Regulatory Limit: Based on the 100mAh battery capacity, the maximum allowed energy consumption for this product class is 2.993 kWh/yr.
• OneKey Performance: The measured value is less than half of the regulatory limit (about 42%). This not only means passing but signifies "excellence." The extremely low UEC value proves that the OneKey Classic is an incredibly power-efficient device; even if left on all year round, its energy consumption is negligible.

2. "Zero Power" Standby Performance

In the "No-Battery Mode" and "Off Mode" tests focused on by the DOE, the power consumption data for the OneKey Classic is 0.00 W. This means that when the device is fully charged or turned off, its internal circuits almost completely cut off unnecessary energy loss, truly achieving "zero standby power consumption."

3. Intelligent Maintenance Mode

In "Maintenance Mode" (after the battery is fully charged), the average power of the device is only 0.26 W. This indicates that the OneKey Classic features a smart charging management strategy that automatically lowers input power after saturation, preventing overcharging damage to battery life while significantly reducing ineffective energy consumption.

Part 3: Future Outlook

OneKey Classic's passing of the DOE federal energy efficiency certification is not just a compliance requirement but a practice of the brand's sustainable development philosophy.

1. Building "Green" Crypto Hardware

As the global energy crisis intensifies, low power consumption will become one of the core competitive advantages of electronic products. OneKey will continue to optimize the power management algorithms of its entire product line, striving to minimize energy consumption while providing powerful computing power and security, acting as a responsible technology enterprise.

2. A Solid Step in Global Compliance

DOE certification is a crucial part of OneKey's global compliance map. Combined with FCC, CEC, and other certifications, OneKey presents a mature, standardized brand image with an extreme pursuit of quality to global users. No matter where you are, choosing OneKey means choosing a top-tier hardware wallet that is internationally verified, secure, and eco-friendly.
