Product introduction:
This Home Use Desktop Power Adapter incorporates advanced LLC resonant conversion technology to deliver 89%+ efficiency across 90-264VAC input range, with ultra-low 0.15W standby power exceeding EUP2016 requirements. Certified by CCC/CE/UKCA and 12 other global standards, its fanless design maintains whisper-quiet operation (<25dB) while providing precision-regulated 55V±1% output - perfect for noise-sensitive home offices and bedrooms.
The adapter features a dust-proof flame-retardant enclosure (UL94 V-0 rated) that passes IEC 68-2-6 vibration tests. Its intelligent thermal management system with "sandwich" cooling architecture limits component temperature rise below 15K, while Japanese 105℃ capacitors ensure 50,000+ hours service life. Compliant with FCC/EN55022 Class B EMC standards, it won't interfere with wireless devices, making it the optimal power source for smart home hubs and NAS systems.

Frequently Asked Questions
What is the input voltage range for this adaptor? Can I use it in different countries?
+
-
Yes, you can. The adaptor has a wide AC input range of 90-264V and supports 50/60Hz frequency. This means it can automatically work with standard wall outlets in most countries around the world, such as in North America (110-120V), Europe (220-240V), and Asia, without needing a separate voltage converter.
What happens if the connected device draws too much current or the output is short-circuited?
+
-
The adaptor is designed with full protection for such events. In case of an over-current or a short circuit, it will automatically enter a "hiccup" protection mode, where it cycles on and off safely without damage. Once the fault is removed, it will recover automatically and resume normal operation.
Is this power adaptor energy-efficient?
+
-
Absolutely. This adaptor complies with the EUP 2016 (Energy-related Products) regulation. It has a high average efficiency of over 89% across various load levels and an extremely low no-load power consumption of less than 0.15W, helping you save on energy costs and reduce environmental impact.
What certifications does this product hold? Is it safe?
+
-
Yes, it is designed to be very safe. It carries multiple international safety and EMC certifications, including CE, UKCA, FCC, and CCC. These certifications ensure the product meets strict standards for electrical safety, electromagnetic compatibility, and environmental safety (it is RoHS and Reach compliant).
What is the typical lifespan of this power adaptor?
+
-
The product is built for high reliability and longevity. Its Mean Time Between Failures (MTBF) is rated for a minimum of 50,000 hours. This indicates a robust design suitable for applications requiring continuous, long-term operation.
For home offices, smart devices, or entertainment setups, this Home Use Desktop Power Adapter delivers efficient, quiet, and durable power. With global certifications and user-centered design, it stands out as a dependable power solution for household needs.
