18V, 3A Power Supply 2.1 x5.5mm
This desktop-type AC-to-DC switching power supply from Shenzhen Ying Hui Yuan Electronics delivers 18V at 3A (54W) through a standard 5.5mm outer / 2.1mm inner DC barrel connector. It accepts a universal 100-240V AC input, making it suitable for use across different mains voltage standards without a separate voltage selector. The housing is ABS/PC with copper windings and an FR4 PCB substrate, and a European-standard AC power cord is included with each unit.
Switching power supplies in the 18V / 3A class are commonly used to drive LED strip lighting, networking routers and switches, small desktop peripherals, and consumer electronics prototypes on assembly lines. The 54W output rating places this adapter in a mid-range power bracket, enough for devices that draw up to 3A continuously without thermal throttling under normal ventilation. The 5.5x2.1mm barrel tip is one of the most widely adopted DC connectors in consumer and industrial electronics, which broadens the range of devices this adapter can power without modification.
Shenzhen Ying Hui Yuan Electronics offers this unit with a 100-piece minimum order quantity and ships in 50-unit master cartons, a configuration that suits importers consolidating freight for retail or wholesale distribution. Pricing, lead time, and specific certifications are not detailed in the listing, so buyers should request these directly from the Shenzhen supplier. The listing confirms the product is intended for export markets, and the universal input voltage supports that positioning.

Sourcing 18V 3A Power Supply 2.1x5.5mm from Shenzhen Ying Hui Yuan Electronics - China Import Guide
Before ordering, confirm that the power supply carries the certifications required for your destination market. CE marking is essential for the EU, FCC for the United States, and UKCA for the United Kingdom. Without these, customs clearance can be delayed or refused. Request scanned copies of test reports from accredited laboratories, not just a declaration of conformity from the manufacturer.
Shipping logistics for AC adapters are relatively straightforward since they contain no lithium batteries or hazardous materials. Sea freight in 50-unit master cartons is cost-effective for orders above a few hundred pieces. Clarify with Shenzhen Ying Hui Yuan Electronics whether FOB Shenzhen or CIF to your destination port is the preferred incoterm, and confirm carton dimensions and gross weight to calculate your landed cost accurately.
On receipt, inspect a sample from the batch for build quality: check that the housing seams are flush, the DC plug fits snugly in a mating socket without wobble, and the AC cord connects firmly. Power-test a unit under a moderate load (around 2A) for 30 minutes to verify that it maintains 18V output without excessive heat buildup. If the adapter runs noticeably hot or the output voltage sags under load, raise the issue with the supplier immediately under the agreed quality terms.
