Electrical help please!!!!!

Hello all,

I’m currently living in an apartment owned by a slumlord and pretty much all of the rooms except the kitchen and bathroom have 2 prong outlets. I’ve gotten some of the grounded adapters because he refuses to change out the outlets and I’m not electrician but I’m still not sure what other possible options there are and what’s the best. These are the thoughts I’ve had so far:

1. Continue with the adapter with a power strip (I need the power strip because I have to many plugs and not enough outlets but also a couple 3 prongs plugs need to be in the same area/outlet or I need multiple to be plugged in at the same time.

Or

2. Have an extension cord going from the bathroom going to a power strip, but with one power strip it would be loaded with a lot of electronics (exact number/range below)

Also for reference I have 2 outlets with a total of 4 possible plug points and they are on completely opposite walls of the room.

For one power strip it would have the internet modem, wifi router, computer, monitor(s).

For the other power strip it would be my tv, cable modem, from time to time my Nintendo switch dock for charging and use with the tv.

Other things that I didn’t mentioned would be chargers for phone and laptop that would go between either power strip.

In total I have 6 plugs that need to be plugged in all the time (2 are 3prong and the rest are 2prong) and 12 at a time (3-4 would be 3 prong at most; mostly chargers and other electronics)

Please if any help, advice and opinion is welcome as I don’t have many choices with a slumlord who doesn’t care for this or thinks that 2 prong outlets aren’t a problem and I’ve tried talking to them about it already.
