all comes down to how many amps the socket and the associated breaker it's connected to. You can plug 2x 6 outlets and plug in 12 lamps and be fine, and plug 1 200,000 BTU AC into 1 plug and blow it.
I have 6 things plugged into one 6 outlet protector like tv, stereo etc. normal stuff and they are not on all at the same time, I was going to get another 6 outlet protector and plug it into the other socket and plug a fan into it this seems okay?..
