5.0 out of 5 stars Reliable and Affordable UPS for Basic Power Backup Needs
Reviewed in the United States on July 26, 2024
Size: StandbyStyle: 6 Outlet (400VA)Verified Purchase
I recently purchased the Amazon Basics Standby UPS 400VA 255W Surge Protector Battery Power Backup to protect my home office equipment from power interruptions. Here’s my experience with this product:

**Pros:**
**Reliable Performance**: The UPS provides consistent power backup during outages and voltage fluctuations. It has kept my computer and modem running smoothly during several short power cuts, giving me enough time to save my work and shut down properly.
**Surge Protection**: With built-in surge protection, this UPS safeguards my equipment from power surges and spikes. This adds an extra layer of protection, ensuring my devices remain safe from electrical damage.
**Compact and Lightweight**: The unit is compact and lightweight, making it easy to place on or under my desk without taking up much space. Its small footprint is perfect for home offices or small setups.
- **Easy Setup**: Setting up the UPS was straightforward. The clear instructions made it simple to connect my devices, and the battery came pre-installed, so it was ready to use right out of the box.
**Affordable Price**: Compared to other UPS units on the market, the Amazon Basics Standby UPS is very affordable. It provides reliable performance at a fraction of the cost of more expensive models, making it a great value for money.
**Quiet Operation**: The UPS operates quietly, which is important for maintaining a peaceful work environment. I barely notice any noise, even when it switches to battery mode.

**Cons:**
**Limited Power Capacity**: With a capacity of 400VA/255W, this UPS is suitable for basic setups but may not be sufficient for high-power devices or larger configurations. It’s best for protecting a single computer and a few peripherals.
**Short Battery Run Time**: The battery run time is relatively short, lasting about 5-10 minutes during an outage. While this is enough to save work and shut down properly, it may not be sufficient for extended power cuts.

Overall, the Amazon Basics Standby UPS 400VA 255W Surge Protector Battery Power Backup is a reliable and affordable solution for basic power backup needs. Its compact size, ease of use, and effective surge protection make it a great choice for home offices or small setups. I highly recommend it to anyone looking for an economical and dependable UPS for their essential devices. I will buy this product again.

I don't know why there is an option to rate the wifi signal. This UPS does not have wifi.
The backup time is not long, but this thing is tiny. It's not meant to keep your server up during an outage.
I use it for my shop heater that doesn't like to lose power while running. It allows me enough time for the heater to do a controlled shutdown and avoid meltdown. Works great for that purpose.

5.0 out of 5 stars You need to get these!
Reviewed in the United States on February 3, 2024
Size: StandbyStyle: 8 Outlet (600VA)Verified Purchase
You know I kinda hate to admit this but the infrastructure in my area is in decline. The power goes out more than ever and we are literally so connected now that many times a a day I think I would rather have internet than water!
With this and as we get older we have decided to have a generator installed at our house. Last summer our electricity went out in June. Louisiana heat in June is no joke. Pushing 60 is also no joke. Pushing 60 with 104 heat index may make you not see 61.
My wife and I fled to another city. My sister and her husband stayed in their home.... for three days with no electric. It's one of those things. You always feel like it'll come back on in another hour... or by dark, by midnight... first thing in the morning.
By the time three days went by my poor sister would have been in tears but she was so dehydrated she couldn't cry. (yes she could have come to Dallas with us but they declined) Everyone affected had every bit of perishable food ruined. So after days with no electric... once it comes on the grocery stores also had no power... then it took a few days after power for them to get deliveries and then the stores were gutted for a solid week. The whole ordeal from power outage to power on to throwing out food to purchasing new food to back to normal was no kidding two weeks. It was awful and I wasn't even here. We fled. We are very fortunate to have another home in another state. All our food was ruined but we purchased food locally at our other home in Texas and just brought it back in coolers.
I say all that to say this. I purchased three of these Amazon UPS systems for our home. We are having a whole home generator installed. These power our modem our router and three of our Amazon EERO modules throughout our home.
In the past as soon as the power goes out it's internet out.
Now with these installed the power to those items goes through the battery. When the power goes out the things plugged in continue to work until the battery dies. I tested this. I have ATT fiber internet. I use Amazon EERO (which are amazing by the way) for my router with three additional modules for mesh coverage. My testing concluded that with just these items on the battery the Amazon UPS will give you about 1:45 before the battery dies and you now have no internet. It takes our new generator about 1 minute to sense a power outage, start and then put power back to the house. In this case our internet will never go down. In the past even with a split second surge it would take about 5 minutes for everything to come back online. These eliminate that.
These are a very inexpensive way to give you a moment to close out what your working on and properly shut down whatever is plugged into it. Simple plug and play install. I highly recommend.

4.0 out of 5 stars 1st Product Did not Work, 2nd Shipment is working Properly
Reviewed in the United States on August 25, 2023
Size: StandbyStyle: 6 Outlet (400VA)Verified Purchase
Update: I did find out a way to make connection when reached out and the provider of the item shipped me a replacement. It did work as we wanted it to work. I moved my rating from 1 star to 4 stars because the replacement did work as expected.

Our product arrived, plugged it in for the 8 hours, and the battery backup won't turn on. 3 of my service techs looked at it, and it's definitely defective. Amazon will not allow you to return it or exchange it. I had to use the Amazon CHAT function to get the refund. I'm going to make one more attempt to order another one. I'd like to use this product. I'll give everyone an update and change my rating if I find the 2nd attempt works.

Since starting working from home, my home PC suffered several times of power outage. Every time the power supply recovers within seconds, but my unsaved work lost. This one is small enough to be placed under the table. And when it is powered on, it is quiet. Only when disconnected from the power outlet, it produces buzz sound.
