At Mingxin Power, we specialize in energy-efficient power adapters that meet EU standards and deliver exceptional performance. This blog presents a real-world case study of how our energy-efficient adapters helped a European smart device manufacturer improve efficiency, reduce costs, and align with market demands. If you're an engineer, procurement manager, or business leader in the EU, discover how Mingxin Power can power your success.

The Client: A European Smart Device Leader

Our client—let's call them EuroSmart Solutions—is a Munich-based company excelling in smart home technology, including security cameras, IoT thermostats, and sensors. By 2023, EuroSmart was shipping 400,000 units annually across Germany, Italy, and Poland. However, as EU energy regulations tightened and customers demanded greener solutions, their outdated power adapters became a bottleneck.

In early 2024, EuroSmart partnered with Mingxin Power to find an energy-efficient power supply that could meet their needs. After a detailed collaboration, we delivered a sustainable, EU-compliant solution that revolutionized their operations. Here's how we did it.

The Challenge: Overcoming Inefficient Power Adapters

EuroSmart's previous adapters, sourced from a low-cost provider, posed three major hurdles:

    1. Low Energy Efficiency: With an 83% efficiency rating, the AC/DC adapters wasted power, falling short of the EU's Code of Conduct (CoC) Tier 2 standards and increasing costs for users.

    2. Regulatory Risks: Non-compliance with upcoming EU efficiency mandates threatened their market access in key regions like Germany and Scandinavia.

    3. High Failure Rates: A 4% failure rate within six months—due to poor thermal design—led to returns, undermining EuroSmart's reputation in quality-driven markets.

With a next-gen smart camera launch set for mid-2024, EuroSmart needed an energy-efficient ac adapter that ensured compliance, reliability, and sustainability. Anything less could derail their growth in Europe's competitive landscape.

The Solution: An Energy-Efficient, EU-Compliant Power Adapter

Mingxin Power has over 13 years of expertise in crafting energy-efficient switching power supply. With our ISO 9001-certified factory and 15 R&D engineers, we were ready to address EuroSmart's challenges. Here's our process:

Step 1: Defining EU-Specific Needs

We assessed EuroSmart's requirements with a European lens:

   • Power Output: 12V, 2A with minimal ripple noise for AI-powered cameras.

   • Efficiency Goals: Exceeding CoC Tier 2 (88% minimum) and ErP Directive standards.

   • Sustainability: Low standby power (<0.1W) and recyclable materials.

   • Certifications: CE, GS, RoHS, and REACH for seamless EU market entry.

Step 2: Designing an Energy-Efficient Adapter

Our team engineered a solution optimized for efficiency:

   • Advanced Efficiency: Using cutting-edge switching technology, we achieved a 91% efficiency rating, cutting energy loss by 8% compared to their old adapters.

   • Sustainable Design: A recyclable, heat-resistant casing reduced operating temperatures by 12°C, enhancing lifespan and eco-friendliness.

   • Safety Compliance: Over-voltage, over-current, and short-circuit protection met EN 62368-1 standards, ensuring reliability.

Prototypes were delivered in 10 days, rigorously tested by EuroSmart in Munich under real-world conditions like power surges and 24/7 operation.

Step 3: Integration Across Europe

We scaled production to 80,000 units in 30 days, tailoring the adapters for EuroSmart's needs. Featuring a universal input (100-240V) and Europlug compatibility, our energy-efficient power adapters integrated effortlessly into production lines in Germany, Italy, and Poland, eliminating delays.

The Results: Efficiency Gains Across the EU

Deploying Mingxin Power's energy-efficient adapters transformed EuroSmart's smart camera line:

1. Superior Energy Efficiency

   • Before: 83% efficiency, wasting power and raising costs.

   • After: 91% efficiency, saving 1.8 kWh per device annually. For 400,000 units, this meant 720,000 kWh saved—enough to power 65 European homes yearly.

This efficiency boost aligned EuroSmart with Europe's sustainability trends, especially in eco-focused markets like Sweden and Denmark.

2. Exceptional Reliability

   • Before: 4% failure rate (16,000 units returned).

   • After: 0.05% failure rate (200 units), thanks to our 0.01% defect rate and CE-compliant testing.

Returns dropped by €180,000 annually, reinforcing EuroSmart's quality reputation.

3. Faster Production

   • Before: Inconsistent adapters slowed testing by 12%.

   • After: Stable, energy-efficient adapters reduced testing time by 18%, enabling an extra 40,000 units for the Q3 2024 launch.

4. Cost Savings and Compliance

EuroSmart saved €300,000 in the first year by cutting energy waste and returns. Full compliance with CoC Tier 2 and RoHS ensured uninterrupted access to EU markets.
