What is special about the outer four outlets in the corners? They are outlined in green ink and have an icon I am not familiar with.
Kent M
on Aug 5, 2020
BEST ANSWER: These four corner outlets are spatially separated from the other outlets to provide clearance for box-type power adapters. There is no difference in surge suppression.

I wouldn't say they are special but this Power Surge Strip is a better power strip than many out there with a higher Joules rating then most which is important for protecting your sensitive equipment. Highly recommend it for any expensive computer, audio TV gear. As for the 4 corners of the outlet they were basically designed to handle those bulky AC transformer plugs which takes up a lot of space possibly blocking some of the ac outlet plugs on a surge unit. They are all protected.

I believe those are for blucky plug ends - things like vacuums/microwaves and such aren't very wide and can be set side by side without blocking any of the other sockets you may want to use. Devices that have bulky plug ins like laptops can be set in the more isolated plugs so they dont get in the way.

This is designed for the larger, wider plugs that sometimes take up more than 1 outlet in the smaller surge protectors.

These are normal power sockets, just spaced out to accommodate "wall wart" style AC adapter plugs.

Does this have any screws on the bottom that allow for wall or under desk mounting?
Alison C
on Jan 16, 2017
BEST ANSWER: It does not have screws on the bottom, however, it does have 4 holes in the corners that, say, the head of a screw would fit into. You could certainly hang it from those holes to mount on a wall. Upside should work as well, the holes get narrower so it can lock into place.

Interested in buying some of these however I have several suggestions or concerns? One is there a power switch on these as I don't see one? Second, since the indicator lights on the strip are real bright can you not just install a rheostat (dimmer) in line with the voltage feeding the lights to dim them as desired? This which would address these real bright issues (not the best to use in a audio visual or bedroom) or sticking them in a box.

BEST ANSWER: Hi, there is a switch near where the power cord connects to this surge protector. The switch is also used to reset the product if the built-in circuit breaker kicks in from overload (if there is too much current draw). About the LED light, we do not recommend modifications to the product since it could affect product safety or performance. Masking the light with electrical tape might be an easier solution if it is bothersome for your specific use, however this may negate the usefulness of having the visible indicator. Thanks for your interest in the product.

You cannot use a dimmer as that would drop the voltage to every device connected to the strip. Simply put, your devices likely won’t turn on unless they’re incandescent lights. Aka, DON’T put a dimmer in line.

When the MOVs fail, does the strip continue to work without the indicator LED? Or does it fail completely? What is the amp (not joule) rating of the individual MOVs?
Christopher B

Does flickering of the green "protected" light mean it's doing something? Is it normal for the protected light to flicker? I presume if protection has failed, the light will either change color or turn off?
Evan

Has anyone tested this to see if the joule rating is accurate? I understand the surge protection industry is rife with false claims -- even with "reputable" brands. And, a higher price isn't telling.

Quality Control and BRIGHT LED Deisgn Flaw
This item was delivered with outlet covers installed backwards, meaning that 4 of the outlets would not accept a plug without manually removing and re-seating them the right way. Also, the green LED on this is insanely bright. This product isn't marketed as a nightlight but it certainly could be. The poorly install outlet guards is a quality control issue, but the bright LED that cannot be modulated is a huge design flaw.
