Why Choose ETOMMENS

When sourcing DC power supplies, switching power modules and custom power solutions for your business, you need a reliable supplier who can balance stable quality, competitive pricing, flexible customization and consistent after-sales support. ETOMMENS, operated by Dongguan Jike Electronic Technology Co., Ltd., stands out as your trusted factory partner for all power supply related projects. We are not merely a product seller; we focus on solving your power supply challenges and supporting your long-term business growth.

Factory Direct Supply Without Middlemen

We are a real manufacturer based in Dalingshan Town, Dongguan, the core electronic manufacturing zone in South China. All our power supplies are produced in our own workshop, from PCB assembly, component soldering, shell assembly to finished testing. There is no trader or intermediate link between us and you. This model helps us control every production step and cut extra markup. Whether you are placing sample orders, medium batch orders or large volume bulk orders, you can get factory-direct prices and stable supply support. We also provide transparent cost breakdown for large custom projects upon request.

Strong OEM & ODM Customization Capability

Many standard power supplies on the market cannot fully match special technical requirements. This is where our core strength lies. Our in-house R&D engineering team can develop tailor-made power supplies according to your technical specifications, drawings or application demands. We support customization on output voltage, output current, power rating, constant voltage / constant current mode, protection parameters, cooling structure, outer housing size, panel layout, interface definition, silk screen logo, outer packaging and testing standards. If you only have a rough idea about your power requirement, our engineers can also offer professional technical consultation and preliminary scheme design. We will confirm samples with you before mass production to avoid any mismatch.

Strict Multi-Stage Quality Control & Testing

Power supply stability directly decides the safety and working status of your equipment. We never compromise on quality control. Our QC system runs through the whole production chain: raw material incoming inspection, semi-finished product spot check, finished product function test, aging test, load test, overvoltage protection test, overcurrent protection test and short-circuit protection test. Every unit will go through long-time aging under rated load before packing. We adopt RoHS environmental standards for material selection. Complete batch test records are kept for traceability, which makes it easier for you to handle quality feedback and after-sales issues.

Rich Product Portfolio for Multiple Scenarios

Our product series covers bench adjustable DC power supplies, high precision power supplies, high voltage power supplies, programmable power supplies, enclosed switching power supplies and constant current modules. Our products are widely used in laboratory testing, R&D prototype debugging, industrial automation, LED lighting, security monitoring, battery charging systems, 3D printing equipment and other commercial & industrial fields. No matter you need high precision for measurement, high voltage for special equipment, programmable control for automated testing or compact power modules for integration, we have matching solutions for you.

Flexible MOQ & Fast Sample Service

We fully understand that new buyers need to verify performance before bulk purchase. We accept low MOQ sample orders for your testing and evaluation. Our regular stock models can be arranged for sample shipment quickly. Once you approve the sample, we can smoothly transfer to mass production. We also support mixed small batch orders for distributors who want to test multiple models at the same time. We will clearly mark lead time for each order type at the quotation stage, so you can arrange your project schedule well in advance.

Professional Technical Support & Complete After-Sales Warranty

Our service does not end after goods are shipped. Our sales and engineering team provides pre-sales technical guidance, parameter matching help and application suggestions. During the warranty period, if any quality failure occurs under normal operation, we will provide timely after-sales solutions including repair, replacement or technical troubleshooting. We keep easy communication channels via email, and we will reply to your technical inquiries and after-sales messages efficiently. We avoid vague excuses and slow feedback that often trouble overseas buyers.

Export Experience & Smooth Shipping Arrangement

We have accumulated rich experience serving overseas B2B customers including distributors, system integrators, equipment manufacturers and research institutes from North America, Europe and Southeast Asia. We are familiar with international trade procedures, commercial invoices, packing lists and shipping documents. We can cooperate with your forwarder or arrange our own shipping channels such as express, air freight and sea freight according to your budget and delivery urgency. We will update order progress and logistics information actively during production and shipment.

Our Business Philosophy

We believe long-term cooperation is built on trust, stable quality and sincere communication. We do not chase one-time high profit; we hope to build stable win-win partnerships with every global buyer. We keep upgrading our testing equipment, optimizing production workflow and improving our product performance to keep pace with the fast-changing power electronics industry. We treat every inquiry equally, whether you are a large enterprise or a newly started trading company.
