I bet you actually have more electronics, a computer, a router, a remote control for the TV (yes it will not run directly off the AAA battery there is a power control system in it) maybe an electric shaver they show up inside all kinds of devices like the battery chargers for your DeWalt power drill and then another one inside the drill itself
Yes, I figured 30. I guessed about 20 light bulbs and I assumed you had a computer if you are reading this some phone chargers Then I assume you must have a CNC milling machine or lathe if you are reading this EMC list The typical CNC machine will have multiple switch mode power supplies and if the spindle motor is DC a supply for that too. 30 is a low estimate. Going off grid means adding even more. For example solar panels will need inverters if they are to supply AC power or DC:DC concerts if used to charge batteries. These inverters can be per panels or one large unit. Same applies to wind power. Likely each turbine has its own electronics. No modern electronics will use big iron transformers. collecting power adds more of these switching supplies and powerful ones at that. I might be an exception but I bet not by much. Where I sit right now I have three computers, 4 phone charges, three AA size battery chargers a router and Ethernet switch and some powered studio monitors and five light bulbs. I think that is 22 switch mode power supplies in just one small size office. The devices are EVERYWHERE and for good reason they save money both in use and in manufacturing.
