Awesome. I think this is better than the refurbish for $160. Thanks!

Got one at this price before at Costco. Great little unit - love it! And the two portable chargers are a real bonus. Recommended!

This is the one with the USB port for UPS with a computer. Unfortunately, it's not a standard protocol and has to be used with their software. People with NAS might not be able to program for shutdown.

I believe this works for Unraid - See here [reddit.com]. I'm not sure about others though but it's certainly better/cheaper than a standard lead acid system. I hate changing batteries in those things. I can confirm if it works for Unraid once I receive it.
