Electric shavers that are designed to be used wet are powered by Lithium Ion batteries that have to charged with house current. The shavers will not work while plugged into the electrical outlet.I didn’t even know this was possible! Wet shaving with an electric.
Would have thought there’s an electrocution risk.
I had a roommate in college a couple of decades ago who would use talcum powder. He’d get a fantastic shave. In fact better than all of us in the hostel using carts and foam.
I never used straight talcum powder as a preshave, although it might work fine. I used a specially designed electric pre-shave stick which was a powder.
