Hey Beyond, hoping to use the collective here and see what other people might use or know about.

About 7 years ago, I bought an Oxx Box CoffeeBox for a coffee maker. It's seriously awesome. Single cup coffee maker, and over the top robust. It is a job site coffee maker and damn near immune to physical damage. About a week ago, the electronics in it started to go on the blink and would suddenly power off, and the problem is just getting worse and worse. So I wanted a new one. Problem is, I found out they have gone out of business, and I am not finding any old stock anywhere. I would buy another one of these, no question. In fact, I want to.

So since they are no longer available, I need to find a suitable replacement.

Criteria:
Water reservoir for multiple cups of coffee
Portable, fine with AC power, and/or onboard battery
single cup K-cup compatible
must be robust, so no glass as I do take these to job sites.

Makita makes a little job that runs on their batteries, but this is a no go for me. Apparently, 1 cup of coffee will kill a 5ah battery and I don't own Makita tools, so I don't want to spend a fortune on more batteries.
