Waiting for my unit which is on the way... Just regarding the battery I would be perfectly fine to charge the reader every day or every second day if it will perform well

I don't want sluggish device lasting 2 weeks on one charge, that's what the Max 1 is. Ok, Max 1 is not that sluggish but my motivation to buy Max2 is to get 2-3x better performance so any random switching between large pdf's, searching etc would work as on typical smartphone.
