    I love the new smaller design and better layout of the actual plugs. No more bulky plugs hanging over.

    • Brand response from TechSupport
      Posted .

      Hello! Thank you for taking the time to share your experience with the CyberPower 450VA UPS.
      We’d like to clarify that standard UPS systems are not designed or recommended for use with CPAP machines or any other medical devices. While a UPS can support many electronics, using one with medical equipment is considered improper use under the product warranty and is not supported.

      For CPAP backup power, it’s best to use CPAP‑specific power stations or CPAP battery packs, which are designed to safely provide the regulated power these devices require during an outage.

      Thank you again for your feedback! CyberPower

    Less expensive to replace identical unit when the battery life ended than to replace the battery. Worked perfectly.

    I bought this Backup Power Supply for wife because she was using her devices without one. A few days after the purchase my power supply gave out. So, the new supply became mine! How is that for timing? It seems to work well. Have not lost power yet. That is the true test of one of these devices. It has 8 sockets. So far so good.
