The EXT-120 is EMP Shield's plug-in model for standard U.S. 120V AC wall outlets. EMP Shield offers it as its portable unit for RVs, campers, apartments, camping, travel and computers. According to EMP Shield, it guards against all phases of an EMP (E1, E2 and E3), coronal mass ejections (CME), lightning and power surges.
It is made for people who cannot or would rather not wire anything into a breaker panel, such as renters, RV owners and anyone running a small 110-volt generator. EMP Shield says that plugging it into a non-GFI outlet protects the entire electrical phase that outlet sits on. In a camper, that means the camper's whole electrical system and every device plugged into it.
EMP Shield calls the plug-in model the easiest way to protect your most important devices, without hardwiring or professional installation. You plug it into a standard wall outlet and it goes to work. When you move, it comes with you.
Many plug-in surge devices only look after what is plugged into them. EMP Shield says this unit protects the entire phase of the outlet it is plugged into, so other outlets and devices on that same phase share the coverage.
EMP Shield describes the EXT-120 as a 15-amp plug-in. It says the unit protects a 110-volt generator or a camper by simply plugging it into the outlet. The unit connects through a red cord with a standard three-prong plug.
EMP Shield rates the plug-in model for a surge capacity of 228kA (114kA nominal discharge current). EMP Shield states that the unit starts shunting over-voltage in less than one nanosecond, moving excess energy away from what is plugged in.
EMP Shield reports testing at Keystone Compliance to MIL-STD-188-125-1, MIL-STD-461G, MIL-STD-464C and RS-105, and states its products are listed by the Department of Homeland Security in its EMP resilience report. A green ON light sits on the front label. EMP Shield is veteran-owned and builds its units in Kansas, USA.
RVs And Campers. Plug the unit into a camper outlet and EMP Shield says the camper's entire electrical system and the devices plugged into it are protected.
Apartments And Rentals. When you cannot touch the building's panel, a plug-in model gives you protection you can set up yourself and take with you.
110-Volt Generators. EMP Shield says the plug-in model protects a 110-volt generator when it is plugged into the generator's outlet.
Home Offices And Electronics. EMP Shield lists computers, entertainment systems, office setups and personal electronics as good uses for the 120V model.
Workshops And Critical Rooms. EMP Shield also names workshops and critical rooms, and suggests the plug-in as an added layer beyond a whole-home system.
A typical power strip surge protector covers only the devices plugged into it. EMP Shield says the EXT-120 covers the whole phase of its outlet and rates it at 228kA surge capacity. If you are comparing, check the power strip's own label for its rating.
EMP Shield makes a second plug-in, the EXT/240V, for 240V outlets that serve washers, dryers, heavy tools and specialized equipment, as well as select RVs and international use. The EXT-120 is the one for standard 120V U.S. wall outlets. EMP Shield gives both the same 114kA and 228kA ratings.
A whole-home panel unit is wired into the breaker panel and stays with the house. The plug-in needs no wiring, moves with you and can work alone or as an extra layer next to a panel unit.
EMP Shield says to plug the unit into a regular non-GFI outlet, not a GFI outlet. The EXT-120 is for standard 120V AC outlets; for a 240V outlet, look at the EXT/240V instead.
Anyone can. EMP Shield says the plug-in model needs no hardwiring and no professional installation, which makes it a fit for renters, travelers and RV owners.
EMP Shield says to use a non-GFI outlet. Plugged into a regular outlet, the unit protects that entire phase.
No. The EXT-120 uses a standard U.S. 120V wall outlet plug. EMP Shield's EXT/240V model is the plug-in for 240V outlets.
Yes. Because it plugs in rather than wires in, you can unplug it and use it at the next apartment, campsite or workshop.
EMP Shield gives a 10-year limited warranty for defects in materials and workmanship and will repair or replace the unit. If lightning destroys it, EMP Shield replaces it for $50 when the destroyed unit is sent in. A separate EMP Shield protection policy can cover damaged connected electronics up to $25,000 when its conditions are met, such as a claim within 30 days with other insurance claimed first.
The EMP Shield Plug-In 120V EMP Protection unit brings EMP, CME, lightning and surge protection to apartments, RVs, generators and home offices without a single wire to connect. If you have questions about your outlet or setup, the Outbound Power team will be happy to help.
