First of all,
its function is basically the same as other plug-type voltage protectors,
mainly to protect our electricity safety and make it more convenient for us to use electricity：
When the voltage is too high or low,our device will automatically cut off power, so as to protect the household appliances.
Secondly,
the biggest difference of the rail type is that multiple lines can be connected,
and when the power of the first line is exhausted or the power is cut off,
it will automatically switch to the next line.
This allows us to use electricity all the time,
and we can also give priority to choosing the most suitable circuit to power our home.
