This high-efficiency-reference AC/DC adapter family has a 5V/4A/20W version and a 5.5×2.1mm DC barrel connection, with 100–240V AC input. Actual black power choices include 24W, 12W, 36W, 20W and 18W, allowing the required electrical version to be specified for the receiving equipment.
Keep the 20W output and other versions distinct
The named 20W reference is 5V/4A, so retain those values together when that is the intended adapter. For another actual power choice, confirm the complete output voltage and current belonging to that version. Include the equipment's required supply and the approved output pairing in the request so that its electrical needs are reviewed against the same adapter as the selected DC end.
Choose the regional plug and cable arrangement
Regional references include UK, US, AU and EU, with a 2464 24–20AWG cable and an explicit PVC jacket. Agree the selected wire construction and other PVC material roles, together with the required plug and DC polarity. Physical length information includes 1m, 1.2m, 1.5m, 1.8m, 2m and custom requirements, which should be carried into one complete end-to-end cable specification.
Review the operating and acceptance requirements
High efficiency is a stated qualitative feature, while 50/60Hz information accompanies the adapter family. Agree the applicable operating and efficiency conditions for the selected output and receiving load. Request the relevant RoHS information, then complete the black adapter version, dimensioned mating, physical construction and quantity with the approved input/output arrangement.





Provide the product reference, selected configuration, quantity and destination. Confirm drawings, applicable ratings and acceptance requirements for the requested build. Lead time, shipping arrangements, charges and any return conditions should be reviewed in the agreed quotation before ordering.
