A new Wifi router would not be the best solution. If there’s an available conduit between the houses I would go for fiber install and get 2 ethernet to fiber adapters then get plug that into your current router or look at directional antenna assuming you have line of sight between the houses.
Only if the Iphone charger is a USB-C PD rated charger.
Not without better cooling systems. Intel and AMD CPUs for higher performance can crank out performance until they hit the thermal limits.
You can do things such as Eluktronics where they have water cooling to dump the heat out faster then heat can be generated.
Batteries are going to be an inverse relationship with performance. The better the CPU the worst the battery life is going to be.
If you are running just generic stuff then a Mac will meet your needs. If you need to run games / Windows only applications then Windows laptops and desktops will meet your needs.
The Framework 16 has a 7840HS or 7940HS these are 35W to 54W TDP cpus. The battery is 85Whr.
Doing the math a minimum you get 1.57 to 2.57 hours using the TDP math. But maximum battery life will be a factor of little power the CPUs can run, (approx 5W) and the various items for the laptop systems, display bightness, , fans, M.2 drives, RAM. (approximately 5W to 10W). Crank up the power savings, reduce the brightness, turn off the Wifi / BT, and turn off not necessary programs.
Using that math you can probably get a maximum of 8.5 hours.
I think i shall pass on any WD based SSD for a while until the hardware faulted SSDs work themselves out of the market.
Its an intergrated GPU, resources are shared with your system memory and there’s a limit of how much RAM it can access. You cannot use to play hardcore games.
All rooms having dual cables pulled to each room with CAT7 wiring.
