The Back-UPS provides abundant battery backup power, so you can work through medium length power outages. It safeguards your equipment against damaging surges and spikes that travel along utility and data lines. The Back-UPS also features automatic voltage regulation (AVR), which instantly adjusts high and low voltages to safe levels, so you can work indefinitely during brownouts and overvoltages.
The Back-UPS also includes unique "green" features, like power-saving outlets that automatically turn off idle peripherals. A high efficiency charging system and "AVR Bypass" also reduce power consumption. With the rest of the Back-UPS standard features, this is the perfect unit to protect your productivity from the constant threat of bad power and lost data.
APC Back-UPS ES 550VA UPS is rated4.67 out of5 by43.

Rated 5 out of 5 byChrisJD from Excellent Upgrade from the 330VAGreat product! Easily identifiable backed up side versus surge protection only. 550VA allows enough time to safely shut down devices. Had a little trouble installing the battery but it was minimal.

Rated 5 out of 5 byBil from Not a good experienceI installed the product on my computer and it caused my system to hang. when I tried to reboot, the system drive was corrupted. I am just now finishing the recovery of my data. The unit is sitting on my desktop because I'm not sure what to do with it. I don't want to try to hook it up again and have it cause another problem .

Rated 5 out of 5 byWalt from Saved my hard driveI bought my first APC after lightening destroyed my hard drive - that unit saved it several times later and lasted six years. My new unit has a ground detection light which told me that the outlet I was using was not properly grounded. I fixed that and now feel fully protected. The only fault I find is that the power cord is shorter than the earlier unit causing me to use an extension cord to reach the closest outlet.

Rated 5 out of 5 bybobscr from Two drawbacksAs other reviews have stated, the plugs are grouped too close together. APC's batteries do not seem to last as long as they used to. I have used APC backups for 20+ years, but this may be my last. I will be doing more research before the next purchase.

Rated 5 out of 5 byG from New UnitThe instructions for connecting battery seem to apply to a slightly different model. In step 2 of Connect Battery, I was unable to remove the battery from the unit. With some difficulty, I slid the battery wire onto the battery terminal.Since this is a new unit I have been unable to rate it's performance other than telephone pass through is ok and and other circuits provide power.

Rated 5 out of 5 byRich of Ned from Excellent for its purposeThis unit replaced an almost identical unit that had functioned well for several years but finally would no longer hold a charge. Battery replacement was an option, but I was offered a "trade-in" that was fair and reasonable. Set up is simple and power seems adequate for a home office computer. We live in a mountain area with frequent power outages, often very brief ones, so this unit keeps things going without interruption.

Rated 5 out of 5 byTony from Works fine, lasts long tmeBought BE550G for home theater PC; have 5 now. Easy to install. If you have Windows 7 make sure you use Powerchute version 2.2 It is not on CD, and currently doesn't show up in software for BE550G. You have to go to software update list for Powerchute Personal Edition. Before BE550G, had BE550R on other PC's and they worked great for both power glitches and several full power outages.
