Power Surges vs 12v adapters...what happened? HELP?

I have my 5th wheel plugged into a 50 amp Surge Guard and all of my electronics such as computers/tv's and other items plugged into a separate power-surge strips inside the RV.
Well, the other day there was a MAJOR power surge that took out our Surge Guard and the 50amp Power Cord....melted both....Thank God I listened to the RV Maintenance man when I bought the RV to spend the $$ on one cause it is an investment. It not only saved the RV, but the Truck parked next to it and my cat inside. :)
So, after all that was said and done, and replaced, I noticed that two out of three items plugged into the inside surge protector power strip were dead. My laptop was fine, but the other two electronics were not working. Found another item today that was plugged straight into the wall that was dead as well.
I bought new 12v ac universal adapters to replace them, and now they work again but I am still confused, what happened to the adapters?
Why would they go out when my RV is suppose to be "protected"?

    If it must be plugged in 24/7, I'd be very aware of the weather forecast before leaving.

    Because surge protectors do have limits, as stated.
  • It was a "man-made" power surge...let's just say someone forgot to turn off the main breaker before digging....not me... I was at work. :)
    Now I learned to unplug before a storm, but I am at work most times when the storms come through, am I to unplug every time before I leave for work? I mean, what is the sense to buy all this power "protection" and not feel safe to leave your RV plugged in?
    It might just be the result of the situation, and in the case of a real electrical storm, we might be ok, maybe? **crosses fingers** Not sure, and yes, I am lucky it was just the adapters. But I like to ask questions so I understand and learn from it. Still a newbie Living in an RV full time.
    Thanks for all your help and comments!
  • Could be the surge was just more than the protection could handle. There are limits. Your probably lucky 12 volt adapters were all you had to replace.
  • Not sure.. what caused this surge? Sounds like lightning. If so, it's best to UNPLUG from shore power during storms.
