Frequently Asked Questions
Can this power adapter charge a laptop?
Yes. The YN120W supports adjustable output of 9-60V with a maximum power of 120W. As long as your laptop's charging voltage and current are within the adjustable range (e.g., 19V/3.42A), it can be used by adjusting the knobs. It is recommended to first confirm your laptop's charging specifications and ensure cable compatibility.
How to adjust the output voltage and current?
The product is equipped with independent voltage and current adjustment knobs (usually located on the side or top of the adapter). Use a small screwdriver or knob tool to rotate clockwise/counterclockwise for adjustment. Note: It is recommended to adjust while connected to a load and monitor the actual output values to avoid exceeding the device's rated range.
Is this power adapter compatible with sockets in all countries worldwide?
The product comes standard with three interchangeable connectors (C6/C8/C14), covering most national standards (e.g., European, American, Australian). However, some countries (e.g., India, South Africa) may require additional adapters. It is recommended to confirm connector compatibility based on your actual usage region.
What does Energy Efficiency Level VI mean? How much power does it save compared to standard power supplies?
Energy Efficiency Level VI is one of the highest efficiency levels mandated by the US Department of Energy (DOE) and EU Energy Efficiency Directives, requiring no-load power consumption below 0.1W and average efficiency ≥87%. Compared to Level V power supplies, Level VI can save approximately 20%-30% energy in standby and light-load conditions, resulting in significant electricity cost savings over long-term use.
Is it normal for the power adapter to heat up during operation? How to ensure safety?
Yes, it is normal. Under 120W power, the adapter's case temperature of 40-60°C is within a reasonable range (at 25°C ambient temperature). The product features built-in overcurrent, overvoltage, and overtemperature protection circuits and complies with IEC62368 safety standards. It is recommended to use it in a well-ventilated area, avoiding covering or placing it near flammable materials.
How do I choose the right DC connector? What are the differences between different DC connector specifications?
To choose a DC connector, confirm three parameters: ① outer diameter (OD) × inner diameter (ID), common specifications include 5.5×2.5mm, 5.5×2.1mm, 3.5×1.35mm, etc.; ② polarity—most devices are center positive, outer negative (center is positive), while a few special devices are center negative, outer positive; please check the device's original adapter label to confirm; ③ rated current—the DC connector rated current must be ≥ adapter output current. This unit comes standard with a 5.5×2.5mm center positive, outer negative DC connector and can be changed to other specifications as needed; replacement is simple and requires no tools.
What is the difference between a PD fast charging adapter and an ordinary adapter?
A PD fast charging adapter supports the USB PD (Power Delivery) protocol. Core advantages: ① Intelligent voltage regulation—outputs multiple voltage levels such as 5V/9V/12V/15V/20V through the USB-C interface, intelligently matching device requirements; ② Bidirectional power supply—supports forward charging and reverse charging; ③ High power—supports up to 100W for PD3.0 and up to 240W for PD3.1; ④ Multi-device compatibility—mobile phones, tablets, laptops, etc. can share one adapter. Ordinary adapters output a fixed voltage (single voltage) and are suitable for powering a single device. If your device supports the PD protocol (such as iPhone, MacBook, iPad, etc.), it is recommended to choose a PD fast charging adapter.
What is the difference between a medical-grade power adapter and a standard power adapter?
Medical-grade power adapters must meet the IEC EN60601 standard. Core differences: ① leakage current—standard adapters have leakage current ≤0.5mA, medical-grade ≤0.1 BF-type ≤0.1mA (patient contact part); ② isolation voltage—standard adapters 2×MOPP (4000VAC), medical BF type must meet BF type applied part requirements; ③ insulation class—must meet double insulation or reinforced insulation requirements; ④ creepage distance and electrical clearance—≥8mm (BF type application). Medical devices (monitors, ventilators, etc.) must use medical-grade adapters; standard adapters are prohibited for medical applications.
What are the warranty period and after-sales service for this power adapter?
The standard warranty period for this unit is 2 years. During the warranty period, non-human-caused damage is repaired or replaced free of charge. Domestic customers receive a 48-hour response and repair completed within 7 working days; overseas customers can arrange DHL/FedEx repair shipping or local agent warranty. For products beyond the warranty period, paid repair service is provided (cost is approximately 30~50% of a new unit). Lifetime technical support is provided (selection consultation, application solution design). Annual framework agreement customers receive value-added services such as priority production scheduling, free samples, and factory inspection support. For bulk purchases (500 units or more), an extension of the warranty to 3 years can be requested.
Does this power adapter have protection functions? What happens during overcurrent and overvoltage?
This unit has built-in multiple safety protections: ① Overvoltage protection (OVP)—automatically shuts down when the output voltage exceeds the set value (usually 110~120%), preventing damage to downstream equipment; ② Overcurrent protection (OCP)—automatically limits current or shuts down when the output current exceeds the rated value; ③ Short circuit protection (SCP)—immediately shuts down when the output terminal is short-circuited and automatically recovers after the short circuit is removed; ④ Over-temperature protection (OTP)—reduces power or stops when the internal temperature exceeds 85℃, and automatically recovers after cooling. After the fault is cleared, the adapter automatically restores power output without manual restart.
What certifications does this power adapter have? Does it have UL/CE/FCC certificates?
This unit is certified to UL (US safety certification), CE (EU safety certification), and FCC (US electromagnetic compatibility). Some models optionally have PSE (Japan), KC (Korea), SAA (Australia), CCC (China Compulsory Certification), etc. UL certification numbers are traceable, and CE declaration documents are complete. For bulk purchases, UL certificate copies, CE declarations, and FCC test reports can be provided together, ensuring worry-free export customs clearance and customer factory audits. For overseas customers with special certification requirements, separate certification applications can be arranged.
What is the service life of this power adapter? Will long-term plug-in damage it?
The design service life of this unit is ≥50,000 hours (MTTF, mean time to failure), approximately 5.7 years of continuous operation at rated load and normal temperature. Long-term plug-in will not damage the adapter. This unit complies with Level VI energy efficiency standards, with no-load power consumption <0.1W and extremely low heat generation in standby mode. It is recommended to unplug the power when not in use for a long time (such as business trips or vacations), which both saves energy and extends the life of the electrolytic capacitor (the aging rate of electrolytic capacitors is significantly slower when powered off than when powered on).
