Most electronic devices are very sensitive to electrical power surges and can get easily damaged if one occurs. So it’s a smart idea to invest in a good surge protector. But if you make the same mistake I made, you may still end up with damaged equipment.
We have had a lot of thunderstorms and rain over the past couple of weeks in Georgia. But I wasn’t worried, because most of the electronic devices in our household are either connected to an Uninterruptible Power Supply (UPS) or a surge protector. I have two APC Back UPS Pro 1500 units in my home office and one in the family room. This ensures, that all infrastructure to support my job remain working in case of a power loss.

A UPS device also doubles as a surge protector and on most you will find outlets marked as “Battery” and “Surge Protection only”. The latter don’t provider any battery backup, as the name implies, but the former include surge protection as well.
During a recent, heavy thunderstorm, the lights in our house flickered for a split-second and I could hear the UPS in my office beep for a moment. “I’m glad I have a UPS”, I thought. To double-check that everything was in order, I walked into my office and noticed my iMac complaining that an external disk was not properly unmounted. That was a sign of power loss of one of the external drives. Plus
