First, it is not intended for use on computers and thus does not have a USB connector to tell your computer to shut down when the power goes out.
Second, and most importantly, its battery capacity is about 6 times that of a standard UPS. For instance, the Tripplite 700 UPS has a 7aH battery, which will provide 400 watts of power for about 7 minutes. This unit has 2 20aH batteries, for a total of 40aH, and should provide 400 watts for about 35 minutes. My big screen, Onkyo surround system, and satellite dish draw about 200 watts, so in an outage, I can probably watch TV for an hour. If my PVR alone is left on, it can run for 5 hours or longer.
Third, this unit has a power meter on it, so you can tell exactly how many watts you are drawing.
If you require a long run-time from a quiet back-up system this is an ideal solution. I use it to back-up power to my weather monitoring computer because I am gone too much during the day to activate my manual backup system.
If you need to stay powered up, and are concerned about intermittent AC power service, this unit is quite nice. It has 26lbs of lead acid batteries (2 12v 20ah batteries) inside, which cost a minimum $50 each to replace. So you are getting over $100 of value just in the battery of system.
It is not as "smart" as some computer oriented UPS units with USB and ethernet ports, which often drive higher output loads (often 1200 or more watts), but its battery is quite large for its price point, and its easy to use for most consumers.
I really like the display of wattage use, although it is not extremely precise. It was good enough for me to tweak my device choices.
I bought this to have a safeguard against my family being left without communication should I not be home to get the generator started in case of an outage. It also provides me a 'no panic' time frame even if I am home, to get the generator going.
I would recommend this product. For the price there is nothing out there to compare. It is a little on the heavy side due to the battery capacity, but I am not planning on moving it so that is not much of a problem. Even though it is heavy it is not bulky and fits under my desk without interferring with my movements.
It does not have any USB capability, but that also is not a deterrent for my uses.
A reviewer mentioned a bothersome beeping. The unit does signal when there is a status change, but it is not constant. it's a feature that is more covenient then bothersome in my opinion. I don't have to concern myself with keeping an eye on it's status. Having the power off is enough to think about. There is also a fan noise when the unit is recharging itself, but again, it wasn't anything that was intrusive, although it was constant for the entire recharge which lasted several hours.Read more ›
