The answer to 'types of surge protector' is there are several common types of surge protectors homeowners can use to protect their electronic devices. The most basic type is a power strip with built-in surge protection, which provides a few outlets with surge suppression. Whole-home surge protectors install at the main electrical panel and protect all the circuits in a house. Plug-in surge protectors are compact devices that can be plugged directly into a wall outlet to protect a single device or a few devices. Advanced surge protectors may also include features like USB charging ports, coaxial/ethernet protection, and LED indicators to show when the surge protection is working.
When choosing a surge protector, it's important to look for one that is rated to handle the power needs of your devices and has a sufficient joule rating to withstand expected power surges in your area. Whole-home surge protectors should be installed by a licensed electrician, while plug-in and power strip surge protectors can often be a DIY installation.
