12 Outlet Power Surge Protector w/ 2 Built-In USB Charger Ports - 3420Joules

Protect your electronic equipment from damaging voltage and current spikes with this Monoprice surge protector.

This model includes twelve protected power outlets, 4 of which are positioned for AC power adapters, and a 2-port 2.1A USB charger. The clear plastic tabs on the sides of the unit illuminate green to indicate when the surge protector is providing protection to your equipment and when a proper ground is detected.

When the protection circuitry has been fully consumed by power and current spikes, the protection light will no longer illuminate, indicating that the surge protector should be replaced. When the grounded tab is not illuminated it indicates that there is a problem with the house wiring and that the ground is not properly connected to the power outlet.

The surge protector has 4 keyholes on the back, allowing it to be secured to a wall or other surface.

Great outlets if you can deal with bright green lights

Pros: Plenty of outlets, sturdy build quality

Cons: Bright green lights on side are....bright

I use this under my desk to power my computer and all its peripherals as well as my bedroom television set. As a surge protector I have no complaints. They outlets are spaced well and can fit a number of wall warts with no issue. It has a large flat footprint but that's fine as it sits on the floor below my desk. There is however, an extremely bright green light strip along the sides of the surge protector. When I first used it, it provided so much ambient light under my desk, it looked like I had popped three chem lights under my desk. However, several strips of black electric tape later, and the light is not an issue.

Pros: Works as advertised
Plenty of of well-spaced outlets
USB charging ports very handy

Cons: Non as far as the product is concerned

They use these where I work and I thought they seemed well designed, especially with the USB outlets, so I decided to get one for myself. It's very handy, I'm glad I got it. I even like the green LED light.

Lights are too bright

Pros: Lots of plugs, 4 well spaced for use with wall warts

Cons: The plugs are all the same direction. Would be nice if some were rotated 90 degrees because there are a lot of plugs now that are designed to fit off to the left or right of a standard wall plug. On this strip that design only works with the 4 well spaced plugs. Also, lights are too bright.

Lights are bright. Would buy again though.

Very well designed

Pros: Many outlets
Spaced outlets for power converters
USB charging outlets

Cons: none (other than the green lights)

This is the best designed and most functional surge protector and power strip I have seen in 15 years of looking. The green (ground and protected lights are a little bright) but if you have any doubts if the ground and the surge protection are functional, they will keep you aware. A little red led would have been OK by me. I am replacing all my power strips with these, even where I don't need surge protection.
