With regards to voltage converters, that is not as big of a problem as it used to be. Most of phone and laptop chargers now support both 110v and 220v. But you should check with your equipment and check that they all support 220v. If they do not then you will need a 220v to 110v transformer. Something like this would be sufficient 2000Watts Travel Adapter and Converter Combo Step Down Voltage 220V to 110V for Hair Dryer Steam Iron Laptop MacBook Cell Phone World Plug Power Adapter for US to UK Europe AU Over 150 Countries https://www.amazon.com/dp/B07N1KWMQT/ref=cm_sw_r_cp_apa_i_ijPfEbJT5XWRA
I found one for about $30 on Amazon that claims to be sufficient.
Not sure how reliable it is though
