Just had this reply from them by email:

“The model we have on our webstore is the standard model (IP-2100-12G) at this time. We are yet to receive delivery of the higher capacity units. Once received they will be priced accordingly and available through the store.”

Another recently released UPS is this small Eaton model with selectable output voltage

That one looks really good jpm! 👍

Yes, that is neat. Dual 2200 mAh batteries, hence longer runtime.

With a "smart" UPS you can also poll it for line status, and send out an E-mail if the power has gone down. Does anyone know of a simple device that plugs into the mains and can be queried via USB or RS232? (Rather than an audible alarm)

I could kludge one up, but hopefully ought to be something cheap and off the shelf, just don’t know of it. I’m. Sure someone has come across something elegant.

One of those smart plugs with energy monitoring that you can flash MQTT firmware on would presumably do the job - when the current coming from the wall drops to zero then the power is out.

Or when it stops sending messages

Yeah I realised that after posting, that something simply not responding to ping could be a good indication that the power has failed.

I’m sure something neat could be kludged up with < £4 Pi Pico; taking a whiff of 12V output from plugpack etc. via some discretes to Pico’s A/D input. When mains fails via 12V, message out through USB. Chuck it in a food container 🤣

Indeed. I just wondered if anyone knew anything neat and off-the-shelf.
