Important info: This unit has 3 x NZ 3 prong sockets rather than the 6 x IEC sockets & 2 x network sockets shown in the pictures, so you do not need to buy any special cords to connect it to your computer/monitor/etc. Aside from that issue, I have no complaints about the unit so far. The unit is very noisy for the first 6 hours while it charges (the internal fan goes full tilt to keep the battery & charging circuit cool) after that the unit is silent. Thankfully I have not yet needed to try running on battery so I am unable to comment on how well it works in that regard.

Remember to keep the original packaging for a couple days after purchasing this so you can return it when the noise drives you and your coworkers insane. Otherwise you'll have a handy doorstop.

I bought a 5E1100iUSB-AU it's working well but I have 2 issues which I think are significant. 1. No USB cable is included in the box, a type A male to Type B male cable is required for communications. 2. No software is included and no there is information in the included manual about where to download it. Fortunately I had a suitable spare cable and I'm running NUT on a Raspberry Pi to monitor the UPS and that works well.

Good price and does the job. it is noisy when charging, that takes a few hours. But for me its in a cabinet and its not heard anyway. Saved us once already!

Simple unit, charged up overnight and plugged in critical components, turned on and works well. Happy with the purchase
