GuanTing Universal AC Adapter 6V 2A Power Supply with 8 DC Plug Tips AC110V to DC6V Power Driver for Digital Blood Pressure Monitor 6v Charger Transformer AC DC Adapter (DC6V-2A)

u/Right_Secret1572 Can you please advise a replacement adapter? I unfortunately can't afford one of the OEM ones and because mine is for a Japanese model, I'm a little confused on what cheaper universal one I should get for USA use. I really don't want to fry the internals!
