Hi Myles,

Fuel Cell??? That is a pretty pricey option.

More than likely it is 100WH (Watt-hour, not Watt) rated.

Which reports:
Output: 12 VDC Nominal
Wattage: 100 W Continuous

So apparently your correspondent was correct after all.

WOW! Infinite Watt Hours. I think we can walk away from the mid-east
right now.

No, actually when you take time to understand the literature (like
Myles evidently has), it becomes quite clear that the limit to the
rate at which energy can be extracted from the power unit is 100
watts, and that the total amount of energy which can be extracted is
determined by the capacity of the fuel cannister; either 130
watt-hours or 360 watt-hours.

So it seems that if you want to be able to rely on this power source
for any extended length of time, 5 watts would not be an unreasonable
load. I'll wager it would even count for 100 extra points at Field
Day - albeit at a cost of $15-$20 a point.
