Can a hotel current regulator increase the current?

According to popular science, when the voltage stabilizer is used when the grid voltage is lower than 220V, the input current will be larger than the output current. The function of a voltage regulator is to stabilize voltage. It does not increase the current that your circuit can handle. If your hotel's internal network cable has been used at a voltage lower than 220V for a long time, and you add a voltage regulator to the main power supply and the voltage stabilizes at 220V, then you can add some equipment to your hotel appropriately.
