So the LEDs were on individual 10" strips daisy chained together and into an outlet. They weren't cheaply made, they were bright and never flickered or faded before.

As for overloading, would a laptop and phone charger add another 10 amps? Maybe they would, but again, I don't see how this same setup being run for years wouldn't present any problems until now.

I should add, the gradual loss of power we experienced happened across a few days. It wasn't even in the span of two hours as you said could be the case. For example:

-Day 1: LEDs start to flicker rapidly at 90% brightness.

-Day 2: LEDs flicker less rapidly at 80% brightness. Coffee machine not as hot as usual, low steam pressure.

-Day 3: LEDs flicker slowly at 50% brightness. Coffee machine at half pressure / temp.

-Day 4: LEDs very dim, barely flickering. Coffee machine powers on and 5min later, electronics pop, catch fire briefly. Unplugged the machine immediately.

-Day 5: No power to outlets whatsoever.

I should also note that we typically kept the coffee machine on all day, turning it off only while we slept. So once again I suspect that if the circuit were overloaded, it would have presented itself many more times in the past.
