I don’t think laptops are much of a concern - virtually every laptop on the planet spends 90% of it’s time plugged in.
All of mine have since the mid-90’s (back then that really shortened NiCd life).
Since they’ve gone lithium I’ve had probably 20 laptops (with multiple running since 2019 as hosts) and seen one spicy pillow - and that was on a year old machine.
My newest machines have charge limit on by default in the hardware. I assume they all do these days as it would reduce support/warranty calls.
Good to keep an eye on them because it can happen to any battery, I just don’t think it’s a huge concern.














Generally a consumer router only needs 2 interfaces - local and external.
Most consuner devices are a combination router, switch, and access point - the switch requires the multiple ports.
