Power when you have no power

I like the slender shape of the battery backup. I like the added feature of the USB-A and USB-C. I’m loving the display that this backup provide. I also like that the plug is able to be flush agains the outlet. I love all the additional surge protected outlets. What I really like about this backup is that it will protect my sewing machine Incase we have a power surge. I love the added protection.

Great value

Wow, this is a heavy duty piece of equipment. I really like the size, weight, and features of this unit. In addition, this sells for $150 elsewhere but is only $100 at Sam’s?!?! Great value! I recommend.

Keeps Internet Gateway Online

Great UPS at a great price. I primarily use it to backup my Internet Gateway Device. This way, when I have brief power outages, my gateway stays up and running. Also, my laptop stays up and running off its internal battery. I can maintain my work-from-home online status for over an hour during power outages.

UPS Backup

Plenty of outlets. USB ports on the front. Leaves outlets available for other items rather than plugging in a USB charger. Like the LCD on the front.

Great UPS

This is a good value and works as advertised. They are great for a home office. I also use one in theliving room for my home theater, it works great for that and gives you a chance to shut everything down if the power goes out and keeps the power even if there is a surge or brownout.

Great

So far so good! This battery backup has lots of ports which is always something you need. It seems to be well built as it is very heavy. Fortunately, I have not lost power. Therefore I have not fully tested the capabilities of the back up, but I’m hopeful it will work.

A good investment for your electronic components.

This battery backup with surge protection is very informative about the incoming power, along with its output power. The unit is well built with quality material and is easy to check its status. I highly recommend it.

12V Battery System, Not 24V like prior versions.

Only uses a single 12V 9Ah battery, unlike the prior versions Sams used to sell that utilized a 24V system with two 12V 7Ah batteries. But in a pinch, when there isn't any other option, this works ok for a hundred bucks (on sale).

Nice functionality, disappointing battery capacity

Functionality is as expected, and nice, but not sure it holds 9Ah as spec'ed. Either that or I got a bad unit: Using it as a power bank during hurricane Milton to recharge an old phone through USB depleted over 50% of the fully charged UPS. The phone is 7yrs old with an original 3300mAh battery, prolly only half that capacity today. Mind you, this is a UPS (and used as such) not a power bank. But 9Ah should still be 9Ah.

I got a lemon/malfunctioning unit

Output voltage is about 90volts. I have tried contacting the manufacturer about the problem but its impossible to get a person on the phone. Also, the front USB-A/USB-C ports don't work. Never have. It wasn't until after the latest power outage that I went to investigate why the fan I have attached to it, sounded slow. Turns out it's always only output 90ish volts (measured on a multimeter).
