The 510-joule rating means your computer, printer, scanner, external hard drive and other sensitive electronic components are protected against strong surges and spikes.
This power surge protector with USB ports features full normal mode (H-N) and common mode (N-G/H-G) line surge suppression. It filters out disruptive EMI/RFI line noise that can cause equipment damage or data loss and exceeds IEEE 587 Category A and B surge suppression specifications.
Charges a Wide Range of Electronic Devices
This 10-ft. (3.05 m) surge protector features two USB ports that produce 3.1A of combined power to charge your mobile devices, including smartphones, tablets and MP3 players. A top storage shelf holds smartphones and other small devices while they're charging.
