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

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.
I would recommend this to a friend pricey
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is the 3rd one I have purchased. They don't last long and are quite expensive
I would recommend this to a friendPerforms 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.
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Does not seem to exceed expectations from a standard battery back-up system. Have not experienced a power-outage to properly test the system.

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.

Worst power battery
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Battery time do not last long. Only one size works and makes this loud beeping sound for no reason. I wish I could return it but due to the hurricane we had in Louisiana I am out of my return period.

Posted .Hello, The SX650U is a UPS(uninterruptible power supply) battery backup. They are intended for use with small electronics such as a computer to provide enough time to save and shut things down properly, not for extended run times.
If there is an issue with the unit, please reach out to our support team at 877-297-6937 and we'd be happy to assist.
Perfect Back up
||Posted . 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.
No, I would not recommend this to a friendGood, reliable backup
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I very much like how this device is built and how the software works. I have had less and less luck over the years with APC products so decided to go with this. Works great so far.
I would recommend this to a friendBestBuy failure to deliver.
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.SInce BestBuy changed shipping companies from FedEx to a grocery delivery company named ShipT, BB has failed to follow up with delivery failures by this company. I have lost all faith in BestBuy and will likely recommend that no other Commonwealth of Virginia agencies pursue any further commerce with this company.

Posted .Thank you for sharing your feedback. We're sorry to hear about the issues you've experienced with shipping. Unfortunately, we are unable to address delivery concerns directly, as they fall under Best Buy's shipping and logistics operations. We recommend reaching out to Best Buy's customer service team to address the delivery failures with ShipT. They will be best positioned to investigate and resolve any shipping issues.
Not sure if wirks
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Power goes out and it beeps but supplied no power to electronics
No, I would not recommend this to a friendBrand response from TechSupport
Posted .Dear Smitty, Thank you for taking the time review this product. If the power is not being supplied to your electronics, we would recommend that you verify your equipment is plugged into the battery back up side of the UPS and not the surge only. The surge only side will no supply battery power when the power goes out.
I don't know
