Any recommendation for a surge protector (strip with a cord that plugs
into wall) for a refrigerator (touch control panel on door) and a
touch control Samsung washing machine (as separate appliances)?

I know I asked and looked for a clothes dryer surge protector earlier
and I conclude there isn't any that will plug into wall. As a result
I may later do a whole house surge protector.

If it matters I can get the make/model numbers for the washing machine
and refrig but meanwhile, what joules, etc.. is a good number to go by
when shopping for surge protectors?
