Finally purchased a power bank. it took me forever to pick one Id like. I was expecting this to be small and what not. It is actually the same size as my galaxy s7, but heavier. However, it gets the job done. I could be at 52 percent I plug it in and 20 min later im at 80. I have checked how many charges it can do on one charge, but I do know when it was at 68% i charged 2 phones (which were at 48) and it dropped to 52%. I was able to get on more charge before I plugged it in to charge.

A lot of "facts" books are, in my opinion, not very well researched and seem to be written hastily and edited poorly. I know I'm picky, but I'm also a professional technical writer. Dan Lewis's books are exceptionally well done. _Now I Know_ is exceptionally well done and really interesting. You can read it cover-to-cover like I did, because each chapter picks up on a thread from the last one, or you can flip through the book and find something interesting whenever you have 15 minutes to spare.

the thermostat is set to low-----although stamped at 60C, or in other words 140 degrees F- it does not heat over 115 F. I found this with both thermostats I had purchased.
