No, I would not recommend this to a friendNice little unit
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I've bought this product before. After several years ir no longer retained a charge. With a new TV I wanted the power protection, so I went with this quality product again.
I would recommend this to a friendKeeps power steady
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I plugged my DVR into it to keep the power steady. Without it even a very short power flux would cause my DVR to recycle, and I would lose a part of whatever program was being recorded.

I would recommend this to a friendGood back power & surge protection
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Have been using CyberPower UPS and surge protectors for many years and thus far have not been disapointed. I gave this one 5 stars based on past performance and realibility of the ones we have bought before. Had bad luck with APC and Belkin UPS's before purchasing the CyberPower brand.

||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Works great in case the power to my room goes off. Lasts for at least 10 minutes with computer/monitor and switches over from the wall to backup instantly. Software works well to connect over usb to my computer to test software/see status.

||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great little unit. Got it for backing up power for wifi router. Works really well. Like it's interface to laptop but has to be plugged in. Would be better if it communicated through wifi.

I do not recommend it.
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I followed the manual's instructions and charged it for the indicated time before using it. As soon as I started using it, it began making the error sound (continuous beep), and I only had a PC, a PS5, and a monitor connected. I had to return it to the store—a disappointment.
No, I would not recommend this to a friendBrand response from TechSupport
Posted .We’re sorry to hear about your experience with the CyberPower 650VA UPS. The continuous beeping you described usually indicates the connected equipment is drawing more power than the UPS can safely support (the unit provides up to 390 watts).
This model is intended for smaller electronics or a single desktop setup. We’d be happy to help recommend a UPS better suited for your system or assist under warranty. Please contact us at 1-877-297-6937 or visit https://www.cyberpowersystems.com/support/submit-a-support-ticket/
