Accell Corporation
GreenGenius® 10 Outlet Home Theater
Smart Surge Protector

By Kevin Nakano

Accell - GreenGeniusSaving power is an important part of keeping your energy costs in check and there is more that you can do in addition to changing the inefficient light bulbs in your house. Accell has just released their new GreenGenius 10 Outlet Smart Surge Protector designed not only to save you power, but also to protect your valuable equipment with its high surge absorption capacity of 3240 Joules. The GreenGenius also provides AC line noise rejection technology to isolates your audio and video equipment from power generated noise for optimal picture and sound quality. The unit provides two banks of AC outlets (Always On and Energy Saver), phone and ethernet protection, and two pairs of coaxial (F-connectors) interfaces.

The Always On outlets are typically for devices that always need power such as phones, network devices, clocks, or DVRs. The Energy Saver outlets are ideal for components that are not typically needed when the user is not watching television such as subwoofers, DVD players or receivers. A switch on the side of the unit is provided to bypass the Energy Saver outlets to always keep them active. A Ground indicator displays when a good ground connection is present.

Surge Protection
The GreenGenius 10 features advanced X3 MOV (Metal Oxide Varistor) devices that provide a longer protection life span than regular MOV's. MOV's are active devices that are commonly used to protect connected equipment from catastrophic voltage transients. Similar to diodes, MOV's
conduct when a voltage threshold is reached. Unlike conventional power strips, the GreenGenius 10 with its Power Stop technology, automatically stops conducting power once the absorption has reached capacity on the protection devices.

Accell - GreenGeniusSaving Power
What sets the GreenGenius 10 apart from other power strips is the ability to respond to components that have gone into a lower-power state. Some devices even in their powered down (quiescent power) state use a significant amount of energy and running them 24 hours a day can greatly increase your electric bill every month. The Master output on the GreenGenius 10 monitors current and is used to trigger (on/off) the Energy Saver outlets. When a device such as a television is plugged into the Master outlet and then turned on, the current increases significantly and the GreenGenius 10 responds by turning on the five switched outlets with a relay. When the television is turned off, or goes into a low power (standby) mode, the line current will drop substantially and is detected by the GreenGenius 10, which then shuts off power to the switched outlets shedding power consumption.

The GreenGenius 10 worked well with some of our components and provided a great way to manage power consumption by controlling the Energy Saver outlets. While the concept of the GreenGenius 10 is pretty straightforward, there are some practical limitation that we ran into when using this product. Not all products have the same current draw in their low power state and some may actually be higher than the threshold level set by the GreenGenius 10, causing it not to respond properly to the low power state. For example, our older 52-inch Mitsubishi LCD television (LT-52148) consumes about 26 Watts in the standby state, which is too high for the GreenGenius 10 to detect as a low power state and shut off the Power Saving outlets. It would have been great if Accell provided a way for user to adjust the current threshold with a simple three-way switch or variable level control. A little more spacing between outlets would have also been useful for those plugging in AC (wall wart) adapters.

The Accell GreenGenius 10 is a clever product that works well if your standby power is low enough to be detected, while providing protection for your electronics. For less than $45, customers can save a substantial amount on their electric bill by turning off components that would otherwise consume power 24/7.
