I use an Autoformer, basically a 38 pound potable transformer/surge protector.
For now (because of it's "value") I carry it in a plastic crate and cable lock it to one of my trailer wheels,then slide it underneath the axles and cover it.
A future project is to build a lockable mount on the trailer I-beam near the drivers side rear (where the 50 amp plug is) and reconfigure my power cords (plugs) so I only handle the unit once while traveling.

Thanks everyone. Was thinking just like a cable bike lock but wasn't sure if there was something else to try and use.

Examples voltage to high or to low it will disconnect.
Wiring issues such as missing neutral or ground, or incorrectly wired like neutral and ground reversed.
A delay before allowing power restoration to protect the a/c compressor from attempting to restart with high head pressures.
Other features may be offered depending upon make/model of unit.

I've never locked mine. Typically I'm close enough to set it under one of the slideouts. I've had a couple of folks ask me what it was. I'll tell them what it does and add "oh I forgot, it's got a feature that it's like an electric fence and will electrocute you if you don't know the correct procedure for removing it".
Never had an issue with it walking away.

thanks for the correction. I was trying to put in simple terms, with google link for more information.

The intent wasn't/isn't correction but rather clarification. I try to keep in mind the broader audience if you will of readers. While I may know what the intent is a "newbie" may not. All good.

Our hardwired is four foot of cable from the trailer's power panel, so it protects the cabling from the dungeon to the power reel at the rear corner, the power reel intern connections and brushes, and the cable that feeds out of the power reel to be plugged it.

Nice "tactic" there Marshall. I guess I'm a little more anal about locking mine up. For the price I paid (for the Autoformer) I feel a little better locking it up. I know locks can not guarantee security but they can create time that no criminal wants to have against them when speed is their friend.
And as mentioned, I have found some space behind the "J"channel skirting on the drivers side rear where I can mount/weld up a hanging and lockable bracket to the "I' beam and just run cords to the unit instead of jockeying it in and out of a compartment for each set up. It will be out of site,out of weather, easy to access and secure.

Mine is 30 Amp so not to heavy/bulky. Trailer came with power cord in a "mouse hole" where the cord stored in a space under the pantry. When I converted it to a twist lock I mounted the EMS in that space. Plenty of space left over to mount the Autoformer in there but just haven't got to it.

No it's not. That's a model 44260 which only offers surge protection and visual circuit analysis but is not an EMS.

The picture they show of a surge protector is a Surge Guard (brand) EMS not a surge protector. Just lots of misleading info there.

Unfortunately a lot of inexperienced folks look at the two devices and think they have the same functions. The recent offerings of surge protectors that offer a visual indication of some of the faults that an EMS device will PROTECT against just muddies the issue further.
An EMS device can be either permanently mounted inside the camper or portable at the pedestal. The EMS will cost considerably more than a surge protector.
Here's the bottom line...let's say two campers setting side by side one connected to a surge protector and one to an EMS. They both leave and return later. During their absence the voltage drops to say 100 volts.
The camper with the surge protector will have a burned up air conditioner and the control boards in his fridge and water heater burned up and possibly his converter before the Amp load gets high enough to trip the breaker.
The guy with the EMS will have no power until the correct voltage returns but the trailer will not have sustained any damage. For my money this option is well worth the extra cost.

In the initial post the OP was concerned about his portable EMS walking off. He posted nothing further that said he had a surge protector. Some things to remember; a surge guard is a surge guard - a device with limited functionalities. A Surge Guard made by Southwire is a brand and can be either an EMS or surge protector.

An EMS is a person riding in an ambulance called when you try to swipe the EMS off my power pedestal.
