What does an EMS do that a surge protector does not?
EMS monitors voltage (high, low, open neutral, reverse polarity) and cuts power when unsafe. Basic surge protectors only block spikes.
Do I need an EMS at every campground?
Recommended. Voltage and wiring faults vary by park. An EMS protects at the connection before power reaches your rig.
Should I get portable or hardwired EMS?
Portable: plug-and-play, easy to replace. Hardwired: theft-proof, always on, requires installation.
