That’s what CBs are for. 
The strip is rated at 15 Amps. Johnny can note the Amperage of the appliances and make allowances.
Oh, I don’t worry about amperage. Like when my fuzes kept blowing, I just put pennies in their sockets before I screwed them in. I’m sure I can hack the power strip if I have to.
I thought CBs were for truckers to talk to each other.
That, too.
You obviously know what you are about.
I cooked corn on the cob in the toaster oven last night. When it was almost done, I warmed up some plates in the microwave oven. It tripped the breaker on the power strip. I was outside grilling the steaks when it happened, but when I came in the plates were clearly ‘done’; so it almost worked. The thing is, they were both plugged into a 1-foot power strip for years and its breaker never tripped. sigh I really wish we had a modern house.
Toaster ovens are pretty hefty, around 1,500 W.
I’ll be glad when the electrician finally comes out to install the new meter, and to replace the fuze box with a circuit breaker panel. Then I can start thinking about re-wiring the house bit by bit.
That is old.
We have a 1956 breaker panel, and should I come into money I would like to replace it with a modern load center.
The house was built in 1934.
It’s odd… Didn’t people use the microwave oven and the toaster oven at the same time, when the house was built? 
They had the same problem on Green Acres.
As for it never blowing the breaker on your old power strip, my guess is that the breaker was bad or you were just at the very edge and the new one is slightly lower than 15 (the old one being slightly more than 15) or this one is more sensitive and the other one had some leeway/time delay built into it.
The Amazon page you linked to said it’s 15a. A toaster is like 9 or 10 just by itself, so it’s not surprising that adding a microwave to the mix popped it.
You could check the nameplates for amp or watt ratings or get out a meter and see what they’re actually drawing.
I believe that microwaves were much smaller in the 1930s.
Why would you want to use the microwave when Uranium oxide on your plates would already automatically nuke the food?
The wonders of modern living!
