That might be too much draw for that duplex outlet (he's saying the dryer is rated at 15a). Go with the adapter but use this one (no need for the circuit breaker). https://www.amazon.com/dp/B081PZCR65/ref=sspa_dk_detail_2?psc=1&pd_rd_i=B081PZCR65&pd_rd_w=XBDMx&content-id=amzn1.sym.386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_p=386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_r=74G6F4RPPZ1X66AJHR1G&pd_rd_wg=yXYe6&pd_rd_r=c8b8be58-b98e-4128-aea8-64a77b604eba&s=hi&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM

and this way, if / when you leave you take the adapter with you, the place still has a 220 dryer outlet ready for use.
