is that why the cell phone has to be charged in such a short peroid of time? Never fully charging???
Could be.
My inverter is set for 110v output. I know the street power has gone out because my lights get much, much brighter, and the microwave actually heats the crap out of things.
It is common for my UPS (computers, modem, router, phone, chargers connected) to activate and beep while the power is still on. Why? The lower limit threshold for activation is 95v.
Sometimes my microwave just won't heat. A cup of water for 5 minutes barely warms it. Low voltage.
It is normal for my outlets to show 80-90v continuously.
