EMI damage? Recently my F150 sat next to a pine tree that took a hit. $5k damages to the electrical. Luckily no damage to my HT/music system however my modem & charger to my laptop did not fare so well.
I don’t think the damage was caused by EMI. More likely from an electromagnetic pulse (EMP).
Edit:
I ran across this device on the Net. Does it really work?
EMP & Lightning Protection for Vehicles (DC-12V-W)
