Re: Portable power pack recommendations and esimate on baterry life

A single 18650 LiPol Cell has a usable power capacity of approximate (hand wavy) 7W/h ( 3.7V 2600mAh is a typical cell) So a single cell PSU should last about 1.5h, a two cell pack about 3h, a 4 cell 6h and so on...

Thank you for this forum. I have gotten a lot of information from you. I may be in a classroom with limited power outlets.

Re: PI top laptops- how usable?

The best VFM way to use a Pi is to plug in a keyboard,mouse and screen. - fraction of the price of a Pi Top setup If your having to move your a class set around then an integrated solution is more convenient.

PI top laptops- how usable?

We will be using our Pis mainly for physical computing. How usable would the laptop be? Can you open the laptop, put on wires and see the circuits in real life, for example?
