Frequently Asked Questions
Can this charger charge a laptop?
Yes. The YN30WPD supports 20V1.5A output with a maximum power of 30W, suitable for emergency charging of most ultrabooks or tablets, but it is recommended to confirm if the laptop's power requirement is within 30W.
Which fast charging protocols does it support?
Supports full protocol fast charging including PD3.0, QC4+, PPS, AFC, FCP, SCP, compatible with fast charging standards of mainstream brands such as Apple, Samsung, Huawei, Xiaomi, etc.
The charger is very small; how is the heat dissipation?
Adopts an ultra-slim 22mm design, but the internal heat dissipation structure is optimized. With smart temperature control technology, temperature is well managed under normal use without affecting charging efficiency.
Does it support charging multiple devices simultaneously?
No. This product features a single-port output design and can only charge one device at a time, but it can achieve universal fast charging by switching between different devices.
Can the charger be used overseas?
Yes. The input voltage range is AC 100-240V, universal for global use. Simply use the appropriate plug adapter for use in different countries.
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.
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 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.
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 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.
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 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.
