Whoever advised me to get a big stabiliser and connect it to the entire apartment so that all my appliances depend on its voltage really did me a favour. Sometimes, when there’s electricity in the area but the voltage is too low to power the AC, freezer and other appliances properly, I barely notice because everything in my apartment keeps working just fine. The only downside is the occasional sound of the stabiliser as it regulates the voltage. Other than that, it’s one of the best decisions I’ve made. I don’t know what such a connection is called but I love it.
