I use them for all the big "brick" plugs, like on external hard drives.

I've never had an overload because only it takes care on things like, hard drives, battery chargers for electronic items, modems, phones, etc

Needed these for some external hard drives with the brick type power supply

I have 2 external hard drives by Seagate and Western Digital and they have these Godzilla sized plugs that they expect me to have space on my surge protector for

They keep my outlets from being blocked by the stupid wall warts from my USB hub and USB hard drive, and I can tuck them out of sight as well.

I run 6 external hard drives on my system that took up 2 power strips. using the power extension cords i was able to cut that down to a single power strip and untangle some wiring under the desk.
