Thanks Mr. Squirrel and Brandon. That was what I suspected.

Mike. That DC-DC charger sounds like a neat idea. Didn't know such a
thing existed. But then I don't know a whole lot about electrical
stuff anyway!

I'll have to reassess my house electrical needs. They're small now,
and I'm sure that somewhat by chance (not totally by design), total
amps needed didn't exceeded the limits of the circuits. Still, it was
ignorant to not calculate loads, or more importantly, future loads.
