Great Price & Works Great
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I needed a small UPS for some low wattage network equipment and this was perfect. So far, I’ve tested it and it works great as long as you don’t put too many devices on it.

Not to happy!!
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Honestly i wanted to return this but it's so far to be told i can't! Im not sure if it's defective or what but it's supposed to have a battery back up and it does but it's also supposed to be surge protected but it still shuts everything off when the powers out and ive had to repair my harddrive a couple times because it lags

Performs as expected for a good price
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The CyperPower 650va unit was on sale, so less expensive (and with more capacity) than replacing the defective battery in my old unit. For the first week the unit emitted an odor, "electrical" . After the first two days I contacted CyperPower customer support who said "we've heard of that before", and that they think it is paint on the transformer. After a month the odor is gone.

Posted .Thank you for submitting your review. There are always larger units but in general UPS units are designed to provide enough time to save what you're working on and to shut down properly. The SX650U is estimated to give about 9 minutes at 200 watts of load. If you are having issues with the unit, please reach out to our support team at 877-297-6937 and we'd be happy to assist.
Move the power button
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I am giving it this rating because the power button is located by the battery backup's outlets and it can be easily covered up by using the top outlet.

Works as intended so far.

Delivery Issue
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This review is not about the product, have used in the past and work very well. My issue is I received a text telling me product was delivered, since I am at home I walked out and no product to be found. I looked at my security cameras and no delivery person. Trying to contact BB through app, web site or phone is next to impossible. I hope they see my review and reach out to me.

Perfect Back up

Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Ibought a similar one last year for my tech stuff, and bought another one for my two big appliances (freezer and fridge) so it is safe when there is an outage. I love this brand and product
I would recommend this to a friendCannot use all Plug Slots
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Like the one I had before with plugs slots facing out instead of in a line -- makes it hard to add large plugs.
