FWIW, find attached a .pdf graph of M102 power consumption. This was compiled 6 
years ago (hard to believe).

  I just tested the power requirements of my 102. With the battery connectors 
connected to a bench supply at 5 volts, it draws a very consistent 65mA. I was 
expecting the current to vary slightly with CPU or screen activity but it does 
not. I'm so used to CPU idle states which, of course, the 8085 does not use :)


  I have one of these kicking around at home 
(https://www.sparkfun.com/products/10968) so I'm thinking to construct a 
LiPo-based AA battery replacement so I can recharge my 102 via USB. There's 
also https://www.sparkfun.com/products/11231 but that's capable of WAY more 
current than necessary and considerably more expensive.

    Yeah, I was wondering about that, especially with WiFi; definitely sounds a 
little high. Too bad.

    Maybe Jeff's solution isn't such a bad idea after all ;-)

    Anyway, the M100 works fine on a "juice pack".
