7 of the Best Ethernet Surge Protectors Reviewed for 2020

0

Last Updated on October 26, 2020 by Marc Edwards

Just like Internet access, having Ethernet surge protectors for our home is a necessary evil these days.

Distant lightnings may strike and send forth electrical surges along the power line. These electrical spikes are usually powerful enough to cause irreparable damage to not only your connected electronics but Internet routers and modems too.

Unbeknown to some people, network equipment can get fried and damaged during strong and damaging electrical current spikes. To safeguard your network equipment from getting ‘fried’ (plus unnecessary outages) by power surges, having a dedicated Ethernet surge protection device is no longer a want but a NEED!
