Matters needing attention in Russian tour and group tour: Can the hotel bring its own electric kettle to boil water?

Bring your own electric kettle to boil water, but you need to bring your own adapter. Not all hotels provide conversion plugs, not because of electricity saving, because electricity in Russia is very cheap, but because Russian plugs implement European standards and the plugs are round. In the border cities of China, it is difficult to buy standard adapters. Need a travel agency to rent or buy.
