Porsche Battery Maintainer

I live in Michigan and bought a 2014 Cayman S this summer, it will be parked in an indoor storage facility WITHOUT electricity.

I've heard that you really don't want to remove the battery as it causes all kinds of havoc with the car (not sure if true).

At any rate I have a Porsche Battery Maintainer (

I'm wondering if I purchased a portable battery power generator like a Yeti 400 if that would work to keep the battery charged using my Porsche Battery Maintainer.   I was hoping I could do that and charge the Yeti (or something like it) once per week.   But have no idea how much the battery maintainer would draw.   Also, the car will be in cold temperatures during the winter months.  

Any thoughts / advice?
