sorry to inform you but the Camco line surge protectors also has a lifetime warranty for materials and workmanship.
Their 55301 30 AMP Power Defender Voltage Protector has a 2450 Joule rating while the Progressive industries EMS PT-30C only has a 1790 Joule rating.
The main thing everyone needs to know is the higher the joule rating the better.
The low voltage drop off on the Camco is a 102 while the power defender is a 104 which is negligable considering they are both within the UL listing required voltage range for electiric devices.
Amazon Prime price for the Camco 55301 is $199.95
Amazon Prime price for the Progressive Industries EMS PT-30C is $248.25
When comparing apples to apples, the Camco is by far the better deal
