Common Questions
What is the warranty period and after-sales service for this power adapter?
This unit has a standard warranty period of 2 years. Non-human damage within the warranty period is repaired or replaced free of charge. Domestic customers enjoy a 48-hour response and repair completion within 7 working days; overseas customers can arrange DHL/FedEx repair or local agent warranty. Products beyond the warranty period offer paid repair services (cost approximately 30~50% of new product). Lifetime technical support (selection consultation, application solution design) is provided. Annual framework agreement customers enjoy value-added services such as priority production scheduling, free samples, and factory inspection support. Bulk purchases (500 units or more) can apply for an extended warranty of up to 3 years.
What is the polarity of the connector for this power adapter? Is it center positive or center negative?
The default polarity of this unit's DC connector is center positive (positive pole at the center), which is the standard polarity for the vast majority of electronic devices. A few special devices (such as some communication equipment, guitar effects pedals) use center negative. Before use, please check the original adapter label or the polarity marking on the device body (usually marked with a "-○ +" symbol, where the dot indicates the center polarity). If the device requires center negative, Yingna can provide a reverse polarity DC connector, or the customer can replace the wiring themselves (does not affect the warranty). Note: Incorrect polarity may cause device damage. Please confirm the polarity is correct before first use.
What is the maximum output power of this power adapter? What load can it handle?
The maximum output power of this unit is determined by the model specification. When selecting the adapter power, it is recommended to calculate the minimum adapter rated power as "Device Power ÷ 0.8" (i.e., P_adapter ≥ P_device ÷ 0.8). For example, if the device requires 200W, it is recommended to choose a 250W or higher adapter. Choosing one that is too small will cause the adapter to overheat and shorten its lifespan, while choosing one that is too large will increase procurement costs and size.
What is the difference between a PD fast charger adapter and a regular adapter?
A PD fast charger adapter supports the USB PD (Power Delivery) protocol. Its core advantages: ① Intelligent voltage regulation – outputs multiple voltage levels like 5V/9V/12V/15V/20V via USB-C interface, intelligently matching device needs;
② Bidirectional power supply – supports forward charging and reverse charging;
③ High power – supports PD3.0 up to 100W, PD3.1 up to 240W;
④ Multi-device compatibility – phones, tablets, laptops can share one adapter. A regular adapter outputs a fixed voltage (single voltage), suitable for powering a single device. If your device supports the PD protocol (such as iPhone, MacBook, iPad, etc.), it is recommended to use a PD fast charger adapter.
Does this power adapter support global voltage input?
This unit supports AC 100~240V wide voltage input, covering mainstream global grid standards (US 110V, Europe 220V, Japan 100V, Australia 230V, etc.), supporting 50/60Hz frequency. Combined with the interchangeable plug design, one adapter can be used in any country worldwide, especially suitable for export product matching and cross-border projects.
What is the Energy Efficiency Level VI? What are the requirements for power adapters?
Level VI is the sixth-generation energy efficiency standard formulated by the US DoE (Department of Energy), mandatory since February 2016. Core requirements: ① No-load power consumption ≤ 0.1W (Level V is 0.3W);
② Average conversion efficiency ≥ 87% (for ≥150W models) or ≥ 87.3% (<150WLevel VLevel VI15~20%Level VIErP
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 the rated voltage (typical value), e.g., for a 12V model, the ripple is ≤ 120mVp-p. For applications sensitive to ripple, such as audio equipment, precision measuring instruments, and medical devices, it is recommended to choose a model with lower ripple (≤ 50mVp-p), or add an LC filter circuit. Excessive ripple can cause audio background noise, measurement errors, and abnormal device restarts. Please contact Yingna technical support with your application details to recommend the most suitable model.
Can this power adapter be used outdoors or in harsh environments?
This unit is suitable for indoor environments (operating temperature 0~40℃, relative humidity 20~80%). Special handling is required in the following harsh environments: ① High temperature environment (>40℃) – derate usage (power reduces by 15% for every 10℃ increase), or choose an industrial-grade wide temperature model (-20~60℃);
② High humidity environment – install a moisture-proof sealed box;
③ Outdoor exposed environment – choose an IP67 waterproof model or install a waterproof box;
④ High altitude areas – cooling efficiency decreases, requiring derated usage. If your application environment has special requirements, please inform us in advance, and Yingna can provide customized solutions.
Can I customize the LOGO and packaging after purchasing this power adapter?
Yes. Yingna Technology provides OEM customization services: ① Shell LOGO – silk screening/pad printing/laser engraving (MOQ 500 units);
② Custom packaging – color box/white box/neutral packaging (brand, model, parameters can be customized);
③ Product label – includes customer model, certification marks, SN code, etc.;
④ Factory parameters – output voltage can be preset according to customer specifications;
⑤ Multi-language manual customization. The MOQ for OEM customization is typically 500 units, with delivery 15~25 working days after sample confirmation. For standard products (no customization), the MOQ is 100 units, with stock items shippable within 48 hours.
What certifications does this power adapter have? Does it have UL/CE/FCC certificates?
This unit is certified by UL (US safety certification), CE (EU safety certification), and FCC (US electromagnetic compatibility). Some models optionally include PSE (Japan), KC (Korea), SAA (Australia), and CCC (China Compulsory Certification). UL certification numbers are traceable, and CE declaration documents are complete. For bulk purchases, copies of UL certification, CE declaration, and FCC test reports can be provided simultaneously to ensure smooth export customs clearance and customer factory audits. For overseas clients with special certification requirements, separate certification applications can be arranged.
What type of plug does this power adapter have? Can it be replaced?
The default plug type for this unit is selected based on the target market (US Type A/B, EU Type C/F, UK Type G, AU Type I, etc.). Many models feature a replaceable plug design (modular plug), allowing one adapter to be equipped with multiple country-specific plug modules for global use. To replace the plug, simply remove the existing plug module and insert the new one—no tools required. If your device needs to be sold in multiple countries, we recommend choosing the replaceable plug version (for greater flexibility) or specifying the plug type for the target market (for lower cost).
Is this power adapter constant voltage output or adjustable output?
This is determined by the model specifications: Fixed voltage versions output the nominal voltage (e.g., 12V/24V), suitable for most standard devices. Adjustable voltage versions allow the output voltage to be adjusted within a specified range via a potentiometer knob (e.g., 9~48V adjustable), ideal for R&D testing and multi-device compatibility scenarios. Usage notes for the adjustable version: ① Disconnect the load before adjusting;
② Confirm the voltage matches the device before powering on after adjustment;
③ For long-term use, it is recommended to fix the knob position to prevent accidental changes. For bulk applications, we recommend choosing the fixed voltage version (more stable, lower cost).
