1, the electricity charge is the electricity consumption for measuring the active power, and it is impossible for any "power saver" to change the active power measurement.
2. The so-called power saver can only reduce reactive current at best, which is not within the scope of residents' charges.
If the "electricity saver" can save electricity, it will make a lot of money to apply for a patent. Is it necessary to make great efforts to promote it? If it really saves electricity, the power bureau will also promote its use!
