Just two years ago my car’s 50 kWh battery weighed around 350 kg, now you can get a 45 kWh battery that fits in the palm of your hand!

You are off by a factor 1000 on the household power consumption (I think these numbers are without heating or assumes that you don’t have electrical heating?). And the voltage could be anything on a magical battery ;)
Whoops, you’re right the values for yearly cosumption should be x1000, or in MWh. So, it’s just enough for a day or two.
That fits with people’s stories of running their homes from their car battery for ~3 days during power outs.
