Interesting. My microwave does exactly that and I use it all the time. It also has "more" and "less" buttons to fine adjust the time by increments of 10 seconds, meaning I never have to enter a number or hit "start" most of the time.
Look at this nerd setting the power level. Just cook it on full blast like everyone else. Just let whatever it is sit and the lava parts will warm up the frozen parts eventually.
I got one of those fancy new microwaves that does 1 minute when you hit 1, 2 minutes when you hit 2, etc. I believe it has saved me about seven octillion eons of cumulative time I would have otherwise spent typing in numbers.
My parents have a microwave like that. It drives me nuts because it's basically a better model of my old microwave. Controls look the same, but function completely differently.
I have one of those and it's cost me who knows how much time and effort. The only times I ever really use are 15 seconds (for melting butter), 50 seconds (for water for baking bread; 1 minute is too hot), and 1:45 for coffee (again, 2 minutes is too hot). I can count the number of times I've actually used the "push 1 for 1 minute" feature on one hand, and instead I have to press an additional "timer" button for absolutely no reason Every. Single. Time. I want to microwave something.
Mine does that but only the 1-6 buttons. And like... if I'm being honest microwaving something for longer than 6 minutes is probably less than 1% of my total microwave usage, but it feels like the greatest injustice ever experienced by anybody when I have to press cook time then 8 0 0 to get my microwave to run for 8 minutes
You can't put the same time every time! Are you nuts?
It needs to be a completely random number you think of right when you're pushing the buttons or they'll figure it out and the device will go off. Don't let them do it!
