Field note 07
Plugs and power banks with published wattage and plug diagrams.
Method on this page. Shortlist by stated plug set, USB-C PD wattage when printed, and current product pages.
A “universal” adapter is only as useful as its plug diagram. We log OneAdaptr OneWorld 140, a widely sold grounded universal adapter pattern (Epicka), and Anker’s high-capacity USB-C banks when the maker prints watt-hours.
If a page lists PD wattage, we copy the number and the source. If it does not, we leave the cell blank.
Columns: logged price, ASIN, Caution, Form, Key number. A figure that is not on the gear note is marked not published.
