Distinct from the POWR316D and POWR320D. 20210908 appears only in the file name, not as a printed issue date. Read with Apple Vision OCR committed beside this configuration. Compliance marks and FCC/IC identifiers in it are the maker's claims, not checked with the issuers. Manufacturer claims, not independent tests.
