Maybe you missed that I was replying to Jeff's message about external power 
sources in more or less the same tone as his; the pic is a mock-up BTW.

Did you notice the "you could of course just keep an AA four-pack in your 
pocket..."

However, I have used a 5-cell (6V) NiCd pack in the past and that does make a 
little more sense, but normally I just keep several sets of 4x3000mAh NiMh 
batteries charged and ready to go.

I have tried a couple of the cheap 2-3000ma USB packs and been somewhat 
disappointed in the running time; I have to get a couple of larger ones anyway 
and we'll see how they work out.

I'm currently trying out some NiZn 1.6V batteries but they're only 2800mWh 
(1750mAh); haven't used the M100s very much lately so I don't have a lot of 
comparative experience to report but the higher voltage does seem to give a 
little more running time after the light comes on.

  I don't quite see the point of that battery holder; why put your batteries 
there instead of just popping them into the laptop?

    You could even top up your bike tires, but you'd still need what started 
all this, the USB<->M100 cable.

    For $2.00 you could use this version (although you could of course just 
keep an AA four-pack in your pocket...):

    That's one of my 'frontlight's in the foreground, optionally powered by 
BarCode connector or internal battery.

      I just got one of these:

      It should power my m100 for awhile.  :)
