Frequently Asked Questions
Does this power adapter support charging laptops?
Yes, the YN45WPD supports 20V/2.25A output with a maximum power of 45W, providing stable charging for most thin and light laptops (such as MacBook, Dell XPS, etc.), but it is recommended to confirm that the laptop's power requirement does not exceed 45W.
What is the difference between the foldable plug and the fixed plug? How to choose?
The foldable plug is easy to store and carry, suitable for frequent travelers; the fixed plug is more robust, suitable for fixed locations. The product offers both options, and you can choose based on personal needs.
Can this adapter be used in high-temperature environments?
Yes, the product is designed with an operating temperature of 40℃, ensuring stable output and safety in high-temperature environments. However, prolonged exposure to temperatures exceeding 40℃ is not recommended.
Is it compatible with all TYPE-C devices?
Compatible with mainstream TYPE-C devices such as laptops, monitors, speakers, lithium battery UAVs, etc. However, some devices may require specific protocol support; it is recommended to check the device's charging requirements before use.
What safety certifications has the product passed?
The product has passed international certifications including CB, 3C, ETL, FCC, UKCA, SAA, RCM, PSE, KC, KCC, complying with multi-country safety standards, ensuring guaranteed quality.
What is energy efficiency level Level VI? What requirements does it set for power adapters?
Level VI is the sixth-generation energy efficiency standard established by the U.S. DoE (Department of Energy) and has been mandatory since February 2016. Core requirements: ① No-load power consumption ≤0.1W (Level V is 0.3W); ② Average conversion efficiency ≥87% (≥150W models) or ≥87.3% (<150W models). Compared with Level V, Level VI saves about 15~20% energy. Adapters exported to the U.S. market are required to comply with Level VI. The EU ErP Directive also has similar requirements for no-load power consumption and conversion efficiency; this unit complies with both U.S. and EU energy efficiency regulations.
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).
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.
What is the plug polarity of this power adapter? Center positive/outer negative or center negative/outer positive?
The DC connector polarity of this unit is factory default center positive/outer negative (center is positive), which is the standard polarity for the vast majority of electronic devices. A small number of special devices (such as some communication equipment and guitar effects pedals) are center negative/outer positive. Before use, check the original adapter label of the device or the polarity marking on the device body (usually marked with a "-○ +" symbol, where the dot is the center polarity). If the device requires center negative/outer positive, Yingna can provide a reverse-polarity DC connector, or the customer can change the wiring themselves (warranty not affected). Note: Incorrect polarity may damage the device; before first use, please confirm the polarity is correct.
Is this power adapter constant voltage output or adjustable output?
It depends on the model specifications: fixed-voltage versions output the nominal voltage (e.g., 12V/24V) and are suitable for most standard devices; adjustable-voltage versions adjust the output voltage via a potentiometer knob within a specified range (e.g., 9~48V adjustable) and are suitable for R&D testing and multi-device compatibility scenarios. Notes for using the adjustable version: ① disconnect the load before adjustment; ② after adjustment, confirm the voltage matches the device before powering on; ③ for long-term use, it is recommended to fix the knob position to prevent accidental changes. For bulk applications, fixed-voltage versions are recommended (more stable, lower cost).
What is the output ripple of this power adapter? Does it affect precision equipment?
The output ripple (Ripple & Noise) of this unit is ≤1% of rated voltage (typical value); for example, the 12V model has ripple ≤120mVp-p. For audio equipment, precision measuring instruments, medical equipment, and other applications sensitive to ripple, it is recommended to choose a model with lower ripple (≤50mVp-p), or add an LC filter circuit. Excessive ripple may cause issues such as audio background noise, measurement errors, and abnormal device restarts. Please contact Yingna technical support with your application scenario, and we will recommend the most suitable model.
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.
