PowerUSB's power strips are designed to help users better control the energy consumption of their PCs and peripherals. Find out if Donovan Colbert thinks these products are good options for SMBs.
The folks at PowerUSB recently offered me four of their unique energy-saving power strips to keep in return for a review. The PowerUSB models, each with an increasing set of features, are: the Standard Basic, the Computer Watchdog, the Smart LCD standalone strip, and the engineering-oriented Digital IO PLC Controller. The devices are not really surge suppressors or UPS solutions, but instead power strips designed to allow the user to better control the energy consumption of their PCs and peripherals.
Feature overviews of the PowerUSB power stripsThe Standard Basic model ($69.99) (Figure A) comes with a MicroUSB port that connects the power strip to your PC via the included USB cable. You connect the power strip and install the PowerUSB software (available for Windows, Mac, and Linux), and you have access to a system tray app that allows you to customize the behavior of the power strip.

On the main screen (Figure B) you can: control the power state of three of the four outlets on the strip (the fourth outlet is always on and intended for your PC), calibrate the consumption meter to a zero state, and access the Advanced and Scheduled menus. The Outlet Details area allows you to set the outlets on or off by clicking the box or by a Ctrl-Shift-Key combination. These key combinations will enable and disable the corresponding outlets even when the app is minimized. You can also select an option here to automatically power-on Outlet 3 when you send a print job, leaving your printer powered off until it is needed. The Output window on this page displays the current consumption and cost of electricity consumed by the attached devices. Figure B

The Watchdog series also features a Shutdown And Computer Off Options menu section that allows you to schedule a daily shutdown and start time for the connected PC. This doesn't just hard-cycle power, but it initiates a graceful OS shutdown. While there are lots of ways to initiate a nightly reboot of systems, the ability to shut down a system and let it sleep until a specified time when it will automatically restart is something beyond the scope of a GPO rule, script, or batch file.Figure G

This power strip has a connector terminal block that will take lead-ins for 5 and 12Vdc signals as well as a lead out for 5Vdc. Figure I

The features here go beyond the typical system administration role and begin to cross over into more advanced electronics engineering projects. Figure J
At first I was a bit dubious about these power strips. These are not inexpensive devices considering they lack surge or UPS capabilities. The construction of the devices seems moderate in quality for the price, but the labels on some of the demo units seemed like they might have been printed on a P-Touch labeling printer. There was an inconsistency here, with the labels seeming very professional on one device, and peeling and somewhat unprofessional on the next device.
Overall, I think these devices are an excellent option for a SMB looking to implement advanced solutions on a small business budget. From automating a waiting room television's schedule to a consultant setting up a RDP server that is available only at certain times of the day or for certain durations, there are numerous examples where the PowerUSB strips could be useful. Despite the upfront expense, I believe that the power savings by turning off vampire devices can pay back for the strips in a short time. From the perspective of a systems engineer, I can see this as an inexpensive solution that provides decent security and accessibility benefits for smaller shops or those with specialized needs.
