Ordered on the company website after a search and it came quickly. Was an upgrade perk from an old unit when I planned to order a new battery. For twice the price of a battery, I purchased this. It's got more backup outlets and filtered outlets (4 instead of 3). Nice and compact. I've already got every outlet used. Has already saved me once. I'm very pleased with my purchase.
Pros: Good Value, High Quality, High Confidence Level in 24/7 Uptime
The device works as advertised. No mus, no fuss, just reliable protection. I have 10 APC devices deployed in my home. There is a reason. I have tried other brands and always find myself comparing them to APC brands.
small enough to fit under the desk; outlets spaced far enough apart for more functional use of adapters; easy battery access; solid construction; good for few minutes of power to keep my devices from sudden shutdowns or electrical surges.
Pros: Easy to Perform Maintenance, Good Value, Good Vendor Support
The APC UPS 550VA did what it was supposed to do during our recent power outage. It seamlessly switched over to battery power when AC power went out. I had plenty of time to wrap up my work and shut down the computer safely. However, the audible reminder tone was frequent and absolutely annoying after a few minutes. I had to turn it off to save my sanity. Later when our cell phones needed a charging, I had to move the UPS to the garage to charge the phones. This was extremely inconvenient and made me wish I had purchased the 600VA which has an audible mute.
Pros: Good Value, High Quality, High Confidence Level in 24/7 Uptime
