Halfway There Review
We like this surge protector because it covers all the bases. I like that (although not pictured above) it has a metal link that allows it to be locked to a pole to prevent theft. It’s a nice addition that seem to be included on newer versions. The LED lights let you know that your connection is safe before you ever plug in. It’s a small price to pay to protect your RV and gear from power issues you may encounter wherever you hook up.
