Minimum 1000 joules for computers. 2000+ joules for gaming PCs and home theater systems. Higher joules = more surge protection capacity before replacement needed.
Yes. After absorbing surges, protection degrades. Quality units have indicator lights showing protection status. Replace every 3-5 years or after major lightning storms.
Basic power strips have NO surge protection - just extra outlets. Always choose UL 1449 certified surge protectors for electronics. Check for "suppressed voltage rating" (SVR) under 400V.
