TL;DR excelent option for Yamaha YPT260 if you have UK or US plug only. My most ridiculous order from AliExpress which i made because my Yamaha keyboard comes with UK plug only (why they can't include all plugs?) So you buy new keyboard, and in addition new need to buy either new power supply, or adapter UK to EU, or order 2 plugs from this seller. New power supply is ridiculous option - i already have one. Adapter option is clumsy and looks awful. So i am glad that i found this seller - it is more pricier than adapter, it has extra head that i don't need, but at least looks perfect, and i do not need another power supply.
Adaptor for US plug APD power supply. Delivery was in time and items looks ok.
