Yes, you can inflate a SUP with the Black+Decker BDCINF18N-QS – Compressor (11 Bar, 12V/230V/18V)

Most SUP boards perform best at 15 PSI, which equals approximately 1 bar on the compressor's pressure gauge. While a SUP is rideable at 8–9 PSI, inflating it fully to 15 PSI is recommended for the best riding experience.
