Customers are saying

Customers find value in the 1500VA Sine Wave Battery Back-Up System's long battery life, strong performance, and ease of use. Many appreciate its pure sine wave output, ample power, and user-friendly display and setup. Positive feedback also highlights the unit's quiet operation and compact size. However, some customers note the system's significant weight as a drawback.

    I really like this. It works well and if the sine wave technology does what they claim that it is gentler on connected electronics, then this will have been great.

    Great power back up unit. I chose this model for its number of outlets, battery operating time, and price. I felt this was a good balance for what I needed.

    The unit did work until there was a power outage. Unit had Error E21 from the start. I contacted CyberPower and determined unit had a fault switching to battery. They immediately put in a replacement order once i provided proof of me destroying the unit. The new unit arrived shortly after and no faults or problems now.

    Exploded...

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Had this for about 2 years, worked ok. Then started giving battery fail light. purchased new batteries to replace (exact same size, voltage, and amperage as original. Also verified all wired correctly connected.) When plugging it back in, the device exploded (loud popping noises, acrid smoke, flashes of light). Opened it up, and several of the transistors had blown. Looking online, this seems to be a common problem with this model. BEWARE!!!!

      Hello Swoody, we are sorry to hear that you had issues with this product. We only recommend that you purchase the replacement battery pack supported for this product, the RB1290X2 as it is the only pack that is fully supported and warrantied for this unit. In addition, all of our products come with a 3 year warranty, If issues occur during that time please don't hesitate to reach out to us as an early battery failure could be an indication of another issue going on.

    This is the third one we have bought. Love we can mute for when the power goes out in the middle of the night. Good runtime out of the 1500VA battery.

    Yes it worked well during the hurricane! It performed as expected. When the power shuts off the unit went into powering my computer until I could turn it off
