Electronics keep breaking down within of 1 time use. Tested input at 122v, but I never had problems other places at exactly 120v.?

You guys say 122v ok within margin of error. But that takes it toll over time. Let alone the electric bill since even a fan will go faster. Electronics are mode more sensitive now which This cant be a coincidence that so many electronics break down within 1 time use or short time use while on surge protectors which are new or older electronics. Power company says its ok but electronics keep breaking down So what is happening?

    Your mains electricity must be very well regulated where you are if it varies only between 120 and 122 volts. In Britain and Europe the legally permitted variations are approximately 217 volts to 248 volts. (Check it if you must, it is certainly wide.) I have not heard of widespread breakdowns of electronics across the UK or across Europe with items nominally rated at 220, or 230, or 240 volts.

    1- the rpm of a fan depends on the frequency .....and it is constant ... 60hz ..

    if it was designed for 120 volts ... if you use it with a 122 volts power, its coils will get hot a little....

    2- for a voltage sensitive device, use a stabilizer ... the motoized type preferred ..

    You must be buying some of the worst crap ever put on the market, 

    or maybe you just have exceptionally bad luck.  

    Either way, electronics are quite tolerant of line voltage variations, 

    especially when they have "universal" (100 to 240 volt, 50/60 Hz) power supplies. 

    There may be a local problem with your power such as a bad line transformer 

    leaking high voltage between the primary and secondary, 

    or a BIG inductive load that cycles on and off frequently. 

    [Switching something ON isn't so bad for other things; 

    it's when the offending equipment shuts OFF that it puts a "kick" on the line.] 

    Without further information to go on, that's as much as I can offer.

    More modern electronics are more forgiving of line voltage, after the power supply, everything is regulated. If 125V will damage electronics so will 108 V.

    Spikes or 'brown outs' can usually be covered with surge suppressors.

    One problem with modern, is most consumer junk comes out of China, as cheap as can be made yet still work. Capacitors overheat for poor engineering.

    On and off, causes mechanical breakdown, anything moving like fans, motors, and disc wear bearing surfaces.

    Your problem is simple, the bargain basement Chinese junk has zero quality control, failures right from the box are common.

    Yep, that expensive Dyson vacuum won't last a year, and that new Iphone you paid $1000 for--you guessed it,,,Made in China.

    You have an unreliable power source.

    You are likely getting repeated "Brown Outs", lack of power drops & surges.

    Have your line checked, install UPS (Uninterupted Power Sources) surge protectors, etc.

    122 VAC is not going to damage an electronic device rated for 120 VAC. Power line surges and/or spike can though. A high quality surge suppressor is a good idea.

    Otherwise, consider Poltergeists.
