Like many here I am a huge fan of the PI EMS.

For those, like myself, who prefer the portable PI EMS it is nice to have a simple analog or digital voltage meter at a convenient location inside the rig. Mine is analog and plugs into any AC outlet and cost less than $15. This enables me to see precisely what the voltage currently is as I engage different AC loads (microwave, water heater, AC etc.}. :C

No question, a portable EMS is probably the best choice for the majority of users since all one has to do is plug it in. :B The downsides are potential theft and the inability to see the display from inside the trailer. Theft can be mitigated by using the included locking ring OR running an extension cable to the campsite power post so you can locate the EMS at the trailer OR for those with electrical knowledge, wiring the portable EMS so it's inside the trailer. I chose to wire my portable TRC EMS inside the camper ...



... but eventually replaced it with a hard wire Progressive EMS which lives under the sofa ...



... with the remote monitor placed where I can easily see it at any time.



That said, I too agree that having an easy to see voltage monitor is a handy tool for anyone and although I do run an EMS I also keep a Kill-a-Watt meter plugged into one of the galley duplex receptacles where I can easily see it at a glance.
