Seems to work



Surge Outlet for TV

Written by: Carl from Worcester, MA on May 20, 2014

Crutchfield Customer Review (What's this?)

Looks to to what it is needed for. Could not give it five stars as it does not fit in a standard box.

Pros: Great for wall mount TV's

Cons: Need to make sure it will fit in the outlet box.

Great design, but too deep to use.

Crutchfield Customer Review (What's this?)

Love the design and the idea behind it. Would certainly be great for reducing the amount of space used behind your tv. Also great for hiding wiring! I can't give it a bad review because, in my particular situation, the box was too crowded and my existing wiring was too stiff to attach to outlet and fit this in the box. I wish I could use it, but I'll have to settle for the plug in surge protector.

Pros: Great design, good look

Cons: Pretty deep

Crutchfield Customer Review (What's this?)

Bought a new flat screen TV and wanted the extra protection. This one has more surge protection ability than others I studied.

Pros: Ability to deflect large surge

Cons: Need a pretty large size box to install it.

Panamax MIW-Surge-1g

Written by: Nelson from Bella Vista, AR on December 25, 2012

Crutchfield Customer Review (What's this?)

I purchased 5 of these units. 4 we put these in a bedroom that we changed into a hobby room with a murphy bed. We needed extra plugs so we changed two sets of one plug outlets to two plug outlets side by side and were able to keep the cords off the floors without adding surge protectors that just lay on floor to protect our TV and other equipment. The other outlet we put in wall for the master TV and we able to remove the surge protector that we had laying on shelve.

Pros: If these work as said no other type surge protectors will be needed. Which keeps it very clean looking. Very easy to install do need some basic electric handyman type skills.

Cons: Pricey but a good floor surge protector is pricey but a good value to protect your equipment!

Just what I needed.

Great way to avoid having a power cord hanging down the wall from your flat screen TV. I would advise that you use a larger 18 cu. in. wall box for mounting as it pretty much fills up a standard size box.
