APC UPS Battery Backup and Surge Protector, 600VA/330 Watts Backup Battery Power Supply, BE600M1 Back-UPS with USB Charger Port

fast switch to battery mode (no latency)
As soon as you receive the UPS, you have to charge the battery without connecting any load: after 24h it will be ready for use (that’s what manual says).First impressions after 3 days of use:This UPS does its job, it has a fast switch to battery mode (no latency): I repeatedly tested the unit by unplugging it from the wall, and the computer remained on without any interruption . The UPS app (available from website) is actually very useful: it allows you to control various settings on the unit, such as enabling or disabling the audible alarm, monitoring the charge percentage / estimated runtime, and, most importantly, automatically shutting down the computer before the battery is fully depleted. The app is available for both Windows and Linux (no macOS support). I use this UPS to protect two computers. According to the monitoring software, I’m using about 50% of the available power. In the event of an extended power outage, my battery charge is estimated to last around 16 minutes. My only concern is battery lifespan: how long will it last? Months? Years? Time will tell.
Note: the replacement battery costs about $70, which is roughly the same as buying a whole new unit.I bought this UPS backup to protect my computers from sudden outages (flickering) of the electrical network, and it works. However, if you need more protection (such as prolonged blackouts), you’ll need a higher performance model with larger batteries.

good low-cost basic UPS
Pros:Easy to replace batteryUSB monitoringUSB charging port that works off battery or utility powerWall-mountable (though screw keyholes are 213 mm or 8.39″ apart, not sure where they got this odd dimension)Entry-level costCons:No LCD displayNo mute buttonI’m not crazy about this form factorBattery is expensiveI have two of these. They don’t have huge capacity so they won’t run anything with a lot of power draw for very long, but if you want surge protection and a computer or other device to not instant-off with a 2-second interruption in power, these work great. There is an easy-to-access, toolless battery compartment though a replacement battery is more than half the cost of the unit, which is not typical. It has a USB-A charging port and a USB-B port to plug into a computer (it comes with a cable) to monitor the power status. I’m not crazy about this form factor and it doesn’t have an LCD screen or mute button (it only has one button) so you have to refer to the manual for the color and blink pattern to determine what it’s telling you and will need monitoring software to know what the load and available battery power are. It’s a good entry-level UPS.

Great investment to protect your PC.
I’m so glad I purchased the battery backup. Lately there have been alot of power failures and surges on my area. I have my monitor and gaming PC protected. There’s about 20 minutes runtime even with my new 850w power supply. That’s plenty of time to save and shutdown. I like the functionality of the PowerChute Serial Shutdown. There are logs to look through and it gives me piece of mind when I’m not home that the pc will power down at threshold that can be set either manually or automatically. It plugs into a free USB. When you download the software and install it, it turns off the native service. The PowerChute software is compatible with Windows 11.

It’s a good battery pack.
Works well, strong battery life and does what it’s supposed to do. We don’t hook it up to bigger appliances but smalls ones like our monitors and game console works perfectly and frees up other outlets.

I bought this because when the power goes out for my pellet stove it would fill up the house with smoke. This runs the pellet stove long enough to get rid of the smoke and shut the unit down exactly what I needed.

The UPS is great, been using it for over a week and throughout power outages and its been nothing but good. Its not the most powerful or not the most in battery life but its certainly enough for the average joe with their router. Its even good for a small amount of mobile power despite not being made for it, i wouldn’t suggest it as you can risj damage to your unit but as for me i am careful so i am fine (i am not responsible for any and all damages made to your unit(s). Any and all careless acts carried out by you is yours and your fault only.) Ease of use is great, just connect the battery, plug it in and hit the power button. Turns right on and starts working immediately, some things to note. In the event of a long term outage, i would recommend checking in on it every now and then as the default alarm doesn’t sound untie the battery is quite low. I would suggest either changing it or just checking in on it after a while. Other than that its a great little UPS and i would recommend it to others. One thing id like to see added is the ability for the ups to change the power button color depending on the SOC (state of charge) would be great to see that instead of a blinking green button till it starts beeping at you.
