Banggood recently sent me a flashlight with a Euro 2-prong charger outlet plug by mistake. It has a built in battery pack so I have to use their proprietary charging cord. Luckily the input voltage range is 100-240V (specified on the converter which is part of the charging cord) so it will work the same anywhere in the world. I just had to purchase a Euro-to-USA adapter for $3. Banggood refunded me $8 for my trouble. Most modern electrical items have this wide voltage range. If they do not, then you need not only an adapter, but also a converter, whether it be step-up or step-down as in this case. The OP could buy a step-down adapter/converter combo to work at 110/120V if desired.
