      Hello, in order for a UPS to function properly it will need to be plugged directly into a grounded outlet and any equipment will need to be plugged directly into the UPS with no extensions, adapters or power strips in between. For more information, please reach out to us at (877) 297-6937. Thank you for your review. CyberPower

    Complete garbage. The directions are simple but the performance of this unit does not match the directions. The performance is not simple because they do not perform.Be advised I purchased two of them and they both had the same outcome.

    Battery backup is not reliable

    Posted . Owned for 9 months when reviewed.
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The battery backup on this unit does not always kick in when it should. When there is a power outage/flicker, it also does not re-engage itself, seemingly, so that it will build up charge again. The manufacturer needs to rethink this product design.

      Hello Panther911, It is best practice to look up the power requirements of the equipment before making a purchase. The SE450G1 is a 260 watt unit. A PS4 and a TV is likely exceeding the capabilities of the unit. If you need assistance with product selection, please reach out to our sales team at 877-297-6937 option 2, and we'd be happy to help.
