How do I change the number of energizing input items and the number of output items in powah?

[tangzixiang-hash]

Excuse me, how to modify the number of energizing input items and the number of output items in powah, I have learned how to modify the type, but how to modify the number of output, I still don't understand very well, please ask me how to do it.
For example, I want to die by typing 7ae2:certus_quartz_crystal and outputting 7X ae2:charged_certus_quartz_crystal. How do I write the code, I tried to change it a few times and it didn't work.

ServerEvents.recipes(event => {
//注册一个充能台事件
// .energizing([inputs, ...], output, energy)
event.recipes.powah.energizing(["64x ae2:certus_quartz_crystal"], "64x ae2:charged_certus_quartz_crystal", 64000)

})
