[ 316 Joules] I found the Vertiv Liebert PSA5 battery backup to be very effective in running my in home office equiptment. I must mention I received this product as a free sample to review. I was not monetarily compensensated to give positive or negative response.
Upon opening the product I found the product suprisingly heavy for the size. It is a good size to have on desk top or easily conceal under the desk (my preference). Product is immediately ready to plug in and work.The outlets area all on the back 5 with battery back up/surge and 5 with just surge protection. If you have non-standard or wide bodied plugs you may need to alternate the spaces as the outlets are close together.
Testing the efficacy when I cut power to the unit the battery immediately kicked in. There is an alarm when the unit battery starts that can be silenced. I would suggest this as I could hear it in my bedroom. Overall great unit, I ran Mac desktop for 5 hours and the battery was still going.

[10x NEMA 5-15R] I received this product for free to review. I like having a battery backup option for my devices I use on our entertainment system. That's what I use it for. It's quite heavy but also small enough to be out of the way visibly. It has plenty of ports to accommodate everything I need to be plugged into it. Overall, very good product and would recommend.

[1-In
1-Out] I've had several; the worst was the most expensive. Complicated, difficult to set up; the batteries died the day the warranty expired (or close).

The VERTIV UPS, however, is easy to instal and provides superior software. Simple to set up and to maintain settings and see condition. While I cannot, as yet, comment on its longevity, so far its a bargain and highly recommended.

[90%] Needed one of these UPS for my rig. Great little unit. This should do the job nicely. Great price! Now I don't have to worry about data loss due to a power outage. Thanks, B&H!

[10x NEMA 5-15R] I got this more as an emergency backup battery than as a UPS for my computer. I have some critical appliances that require a short by heavy load and can't really have them down for one or two days if the power goes out. I'm reasonably sure this UPS will keep them running on minimal usage during a short power outage. Either that or I can run my internet gateway for several hours. Either way, it's some peace of mind.

[RJ11, RJ45] I needed a UPS system for mainly my routers and switches. The DEAL Zone had a very good deal, so I jumped at the sale. The delivery was fast. I read all the instructions for charging up the unit, 24 hours is what is stated. I let it go for 72 hours. I had no problems, It worked like I hoped it would. I waited a week later then did a test power failure. I shut off the power. Everything worked alarms sounded and all screen notifications let me know the status. Thanks B+H Photo for offering great deals. :)

[ 316 Joules] I reviewed a 1500VA UPS unit earlier after purchasing it last summer for my work-at-home workstation. It is still working fine. When the UPS's were offered again on B&H's daily Deal Zone, I purchased three additional units - (1) 1500 VA and (2) 500VA. As I commented earlier, the packaging does NOT come with an Installer/User Guide, but it is available online and a MUST-HAVE. I proceeded to charge the units for 24 hours prior to adding the intended devices for UPS/surge protection. The next day, the alarm sounded on one of the 500 VA units, and it displayed Error Code E06. The User Manual identified the Error Code as, Battery Charge Failure - Turn-off the UPS and call Vertiv technical support for a replacement unit. I emailed Vertiv and their Customer Service representative responded immediately and walked me through the replacement process. Vertiv replaced the unit under warranty and provided a shipping label for returning the defective unit. Vertiv's customer service is outstanding, just like B&H's. I previously gave this 4-stars because of the lacking User Guide, but that has been forgiven. All four of my Vertiv Liebert UPS units are functioning satisfactorily.

[12 Hours] works well
great price
just the right size

[NEMA 5-15P] Works just as well as a competitor at a better price.

[90%] I recieved this UPS free as a trial to see how it compares to other UPS battery backups that are available. This is very easy to plug in and has 10 total outlets, 5 battery & surge protected outlets and 5 surge protected outlets. There is a panel to easily monitor the power. All cables included and easy to read directions available online. I would recommend this to my family and friends
