The Cone of Shame - Is it okay?

Dear fellows. Recently, my puppy broke 4 mobile phone chargers, a usb connector, router connector, an Ethernet cable and just last night our Electric Fan short-circuited causing temporary power-off in our unit. I was really mad at her but then I can't do anything except stare at her and shout her words while pointing at the things she broke.
She chewed on the wires mentioned above though she already have a chew-bone, a toy ball, a pull-rope and a number of mats and rags. Every time she did it, I can't do anything to the poor puppy. I put her in her cage but her whining and whimpering is enough to let her out again after a few minutes.

Recently, I've been reading on how to prevent this but they doesn't seem to work. Just want to ask you out there if using e-collars or "cone of shame" is okay to use as punishment? I know I've spoiled her somehow but she's a dog and its natural for her to chew things specially while in the puppy-phase. Any advice would be great..
