CyberPower M1100XL Medical-Grade UPS System, 1100VA/880W, 6 Outlets, AVR, Tower

We needed a UPS for a GE Ultrasound unit and this more than met our expectations. Looking to purchase additional units in the near future.

Using it for my CPAP machine, alarm clock, small lamp, phone charger. Works amazing.

A very solid machine that operates silently. We started having power outages so I got this for my cpap machine and it works very well.

This UPS is designed for use in medical setting but NOT to be used for keeping medical devices on. Only for non-medical or medical computer devices. So don't buy this thinking you can plug in your personal medical equipment, make sure to check with the company first. Picked this up on a sale to try and use it with my desktop PC setup. Even though this is a *modified* sine wave and not a Pure Sine Wave unit it is able to keep my LG C2 TV and my desktop PC which uses a Corsair RM850 PSU on during a power outage, brown out, etc. My whole system pulls about 110W - 140W when not gaming and the UPS can keep things on for at least 15-20 minutes. The major downside to this unit is the fan that cools the internal components. It kicks on at about the 70W range which is only about 16% capacity. So basically the fan is on the whole time my computer is on, which adds quite a bit of noise because it is a small fan that spins at a high RPM. In an office environment where there is already white noise it is ok, at a quiet home office this adds a lot of noise.

Product was damaged. Was told not not send it back but to dispose it. We did as directed.
