Power outages are a reality that can threaten your productivity and sense of comfort. The XPower PowerSource 400 is the perfect backup power solution for the small-office and home-office market. During a power outage, it will supply up to eight hours of uninterrupted backup power to devices such as a small TV, a radio, a laptop computer, a desktop and LCD monitor, an inkjet printer, a copier/printer/fax/scanner, an Internet modem, a VoIP phone, a cell phone, or a cordless phone. Until now, backup power products on the market have only been able to provide limited backup power during outages and not extended runtime like the XPower PowerSource 400. With the XPower PowerSource 400, you will be able to keep working and stay productive--and meet those important deadlines. The XPower PowerSource 400 switches to backup power automatically when a power outage occurs. This happens seamlessly so that the electronic devices that are connected to it won’t sense the power outage. They’ll operate off the XPower PowerSource 400’s charged battery for hours. When grid power returns, the XPower PowerSource 400 switches the devices back to utility power, recharges its internal battery, and enters a standby mode until the next outage occurs.
Works as it says.
This is an early review in that I have not had to witness a lengthy power outage to determine its run-time, but from initial experience it seems to run as expected. Some things I do want to pass on to other people, is that this UPS is like most others, even though its from an inverter specialist, and will not operate on an existing modified sine-wave inverter. This won't bother most people however. Others should just note that it is very large as is needed for the run-time it is able to offer, and weighs a good amount too. It does not have a continous audible alarm when operating in backup mode. The documentation states it is a modified sine wave inverter, however I have not checked to see what the exact output looks like. I don't have any delicate equipment connected, so I cannot know if it would cause buzzing from audio equipment or picture distortion in video equipment.
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.
