Be careful with these.
When target had them for $14 clearance, I bought 2.
Both seemed to work when I did a test run.
But a week later, when power went out, they didn't do squat.
No power, just beeped.
Exchanged for another, and they wouldn't even pass initial test.
Then I got the $30 IBM unit at CC ($90-$30MIR-$30MIR), and saw what a real UPS is supposed to do,
These CyberPower units have a hard time backing up a cordless phone.
All 4 CyberPower units, after charging for a week, did not have enough power to run a 45 watt monitor at all!
Tech support confirmed all were bad, and they were bought 400 miles apart. (not a bad batch)
Previous thread for $14.95
Previous thread when it was $12.44 for the 325sl, and $19.94 for the 500sl
There is a reason these CyberPower UPS keep popping up for under $15. It's called junk.
