* If anything needs that protection, then everything needs that protection.* Protection is always about where hundreds of thousands of joules harmlessly dissipate. Your concern is a rare and destructive transient that can overwhelm protection inside a Mac and all other household appliances.
IOW best protection at a Mac is already inside the Mac. Surges that are hundreds of joules will even be converted by a Mac into rock stable, low DC voltages to safely power its semiconductors. Destructive surges can be hundreds of thousands of joules.
It is called hearsay or junk science reasoning.Īdd facts. Because someone said you need 600 joules, that proves you need 600 joules.
