Not unusual when beginning with a simple proposition. A voltage difference - a spike - is causing those failures. An major anomaly between neutral (white) and hot (black) wires is made irrelevant by circuits already inside all electronics. However, the wire that can bypass all that 'robustness' is safety ground (green or bare).
Those power cycling devices create spikes that any ground wire would even make totally irrelevant. Except if the ground is connected to those many devices AND not properly connected to a breaker box safety ground bus. Sometimes that defect can be measured with a meter or even the crude and less reliable three light tester. Sometimes it cannot.
One trick used to find a defective ground is to temporarily connect an incandescent bulb between the receptacle hot wire and safety ground. Major caution: if a defect exists, then you are putting up to 120 volts on all other appliances. Best done with other appliances disconnected.
Now, when the bulb (hot to ground) is lit, then a meter must measure VAC (voltage) from that ground to neutral wire. If more than 2 volts, then you have quickly identified (without any doubts) a serious wiring problem.
