Pros: Seems to work plug and play with my Synology DS1513+. With just the NAS plugged in to the battery, at 100% battery I get an estimated ~2812 Seconds reported to Synology.
Cons: After simulating power failure by unplugging the UPS, I checked my reported battery level and within 1 minute I had dropped down to ~75% of battery. I tested it again and left it running longer, under 5 minutes (with the NAS in safe mode) and it only seemed to drop to ~65%. I thought that I had bought more than enough battery for my NAS power usage, so I'm left wondering if the UPS power levels are not reported correctly.
Summary: I only get between 30 and 35 minutes of battery, so if a data transfer is running over night and the power goes out for more than 30 minutes I'm in trouble. But that's more of my budget talking than an actual con of the device.
Pros: Easy install, no noises coming from the unit. Windows Vista detects it as a battery without the need to install the included software (please don't ask about the Vista). Can now image customer drives and make backups without worrying about power loss.
Cons: Very little room for transformers. I have a laptop, external HDD, and a HDD dock attached to the battery side. The dock and external drive have large transformers so a powerstrip was needed. (I don't like to plug one surge protector into another)
Summary: We have 14 of these backups, one on each workstation at our business. We've tried other backups over the years, but these are the ones that last the longest. And it's relatively easy to replace the batteries.
Summary: This is a nice compact unit. I like having the outlets on the back of the unit. One of my UPS units has the outlets on the top and they get dusty. I will replace it with one of these when the battery fails.
Summary: The backup power and surge protector came quickly and appears to work well. Only problem is that the plug receptacles on the back are a bit too close together so that plugs with transformers attached to the plug don't fit well and required some moving of plugs around in order to be able to plug the bulkier plugs into the surge protector.
Summary: Found this product to be easy to install, works well, especially with a generator backup. Old UPS system cancelled my computer while the generator took 12 seconds to come on line when power failed. This UPS System 's batteries take right over with no computer interruption.
Summary: Kind of scary knowing more about the power sent to my home than the power company knows.
Pros: Does what it should. Download the latest version of Power Chute for monitoring and PC PEACE of mind - when you are not at home that if your power goes out you PC will save your data and shut down safely.
