If I was not wrong, the ones who are reading my article are Engineer or Buyer (if you are not either of them, please let me know under the comments I will update my article for you, thank you in advance), so you must understand how important to choose a reliable power adapter manufacturer who could have long time cooperation, it will make you more profit and leave you more free time for your family and personal life.
This page is going to discuss with you how to choose a reliable power adapter manufacturer.
What does a power adapter manufacturer do?
Power adapter manufacturers are charged with the responsibility of manufacturing power supplies.
Develop and design the power adapter.
According to the requirements, to achieve the purpose of the power supply
converting the power from AC to DC and delivering the power to the circuit components at the correct voltage and current, voltage, max current, voltage ripple, and heat loss at maximum current are the important parameters to considering. (by R&D Department)
The design includes:
- PCB circuits design, components choosing, such as a transformer, a diode, and a capacitor……
- Case model design or choosing.
- Suitable cables choosing…
Prototyping and testing the performance,
Make sure all the parameters are satisfied. (by R&D team)
Sourcing (by Purchasing Department);
Electronic components, pcb board, casing, cable, plug……
Assembly and testing
- PCB assembly: uses either through-hole-technology (THT) or surface mount technology (SMT) to solder different parts.
- AOI testing: use an automated optical inspection (AOT) testing machine to check if every component soldered well.
- Ageing testing: is used to estimate the useful lifespan of the power adapter and its shelf life, usually in a controlled standard testing environment to let power supplies work to determine the long-term effects of expected levels of stress within a shorter time. The performance of a power adapter directly depends on the heat dissipation, let power supplies work in a testing environment could test a lot about the performance.—It’s required for a safe power adapter product.
- Case, cable, plug assembly: professional assembly technology combines PCB board, case, and cable together sturdy and works stably.
- Function testing: after the ageing testing processing check if every function is still working well, and if all the parameters are satisfied.
Final testing and packaging
- Final testing: all power supply must pass the pull and drop testing before shipping.
- Packaging: according to different customers’ requirements, the power supplies will be packed in bubble bags, white boxes, or color boxes…
What features are important for choosing a power adapter manufacturer?
Engineering or OEM capacity that satisfies your needs.
- With R&D team is better, and makes the factory reliable, and means their products more stable maybe, and they got the power to solve the problem and provide after-service.
- Especially when your projects need to customize some parameter, function, or OEM needed, you better choose the manufacturers with the R&D team.
Manufacturing Capacity that manufactures for your demand.
- Production Line: a factory could have 1 to 100 lines for different duties, it’s not the more the better, either the less the better, only when the manufacturing capacity is good enough to manufacture for you is good.
- Equipments and Technology: if the manufacturer has the necessary equipments and technology, maintenance and calibration schedules have been met and documented for manufacturing and testing is quite important.
- Workers: experience means a lot for the workers, the factory with experienced and trained workers is important and necessary.
Quality that meets your needs.
There is no highest or lowest quality for any product in the market, find the one that meets your needs is well. There are some stanard requirements for a factory that could relate to quality:
- ISO: an indicator of quality and signals an electronics manufacturing system with integrity, normally factories need to follow ISO standards to manage their quality system.
- Certification: holds an accountable for the quality of a product, where materials were sourced from, who can gain access to the designs and other information, and how a product is handled post-production. According to your market requirements, choosing the power adapter manufacturer with suitable certifications is much easier for you.
- Testing: for power supplies, testing during manufacturing is so important for safety and quality control.
Products range that match your project.
What kind of power supply do your products require? There are different types of power supply in the market, and not all power supply factories manufacture all types. Make sure the factory manufactures the type of power supply you needed.
Understand the voltage, current, and power your electronic device needs and all the related parameter, to check if the factory’s product range is covered.

Reasonable price that benefits your projects.
It’s so strange that there is also a higher price and a lower price in the market, but trust me the different price gives you the different energy for your electronic devices, choose the one that can benefit your projects.—oh hell, I know that it’s a complicated thing to do.
Summary tips for you
1. Survey more than one manufacturer.
You can start your research for a reliable power adapter manufacturer by checking their website and discovering as many details as you can. From there, you will narrow your list to at least three different manufacturers that you want to survey.
Then, you could pick up your phone to have a call to arrange a face-to-face meeting. Meet face-to-face with people, you get a better sense of what it would be like to work with them, and you are capable of telling better whether they would be a good fit or not.
2. Ask more.
Never hesitate to ask any question you are interested in. All the information related to their team, manufacturing capacity, quality control, product information, certification, price, warranty, and after-sales service……, could be your question to know your potential partners.
3. Check up on all documents and certifications.
During talking to the manufacturers, better to have the credential documents about what they said.
Especially for the certifications, it’s quite well to check if all of them are valid and true.
4. Price is important, but so is value.
Don’t treat the cost as everything.
