About Surge Protection Devices
Surge protectors protect electrical devices from voltage spikes and power surges. They limit the voltage supplied to a device by either blocking or shorting to ground voltages above a safe threshold. If voltage surges or spikes you want to be sure you've got the best surge and circuit protector to keep your electronics from getting destroyed. It is also important to note that not all power strips are surge protectors. Although many look similar, a surge protector will have a “suppressed voltage rating” while a power strip is essentially an extension cord with multiple outlets.
