However, the limited number of outlets means it might not be suitable for more extensive setups. Also, being a direct plug-in unit, it might not be as flexible in terms of placement compared to power strips with longer cords. Still, for users needing reliable surge protection for a couple of devices in a compact form, the Tripp Lite Isobar ISOBLOK2-0 is a strong candidate.

The Cable Matters single outlet surge protector is a compact and straightforward option for protecting treadmills and other home electronics from power surges. With a joule rating of 1350, it offers decent energy absorption to help prevent damage from sudden voltage spikes.

This surge protector is a practical choice if you need a simple, reliable solution for protecting your treadmill or one other key device from power surges.
