    Excellent choice for a backup battery. I use it on my internet and home network to keep wifi during outages. More than enough and always works unless the provider goes down.

    These things save thousands of dollars in expensive equipment. I have to have one on my TV, PC, router/modem, Xbox, and security system that has power over ethernet. Gets you through 99% of spikes and outages without powering down.

    Don't know how it is as a backup since I haven't had an outage since purchasing. A bit heavy. But has plenty of outlets.

    I got a good deal buying an open box. I think they are worth it to have a little back up power to get a chance to power down some devices in the event the power goes out.

    The purchase of this back-up system was money well-spent. I’d recommend this to anyone who works from home. To lose power in the middle of a project can create both lost productivity and unsaved work. It’s a small investment that will pay for itself within one power outage.

    This is set up on a wireless home phone base and a table lamp. It's really nice being able to continue a phone call or place calls during storms without any worry. The USB ports also help keep cell phones charged. More than happy with this unit.

    cyberpower is a very good brand. ideal for a mac mini or mini pc, and display.i replaced my 1500va cyberpower, that went out after 9 years, with this compact unit. only wish they would add a small lcd to show remaining power. overall a good buy.
