Hi Mike and list:
International voltage is a pretty big thing. The US is probably the only
country in the world that uses 110 Volts at 60 Hz. The rest of the world
uses 220 Volts at 50 Hz. But that is only the simplest difference. There are
numerous styles of connectors that are used by countries other than the U.S.
If APH supplied an A.C. adapter for the Book port, they would be obliged to
supply the appropriate adapter for each country where the Book port is used.
Since battery types are more standardised on a world wide scale, it is one
less worry for them. While I can appreciate the potential benefit of an A.C.
adapter, having to carry one of those along on the off chance that you might
need it would reduce the portability of the Book port, itself a considerable
contribution to its success. So you can see that this would add more head
ache than convenience. APH is right not to pursue this. It is far simpler to
accept a small amount of personal responsibility and carry a set of extra
batteries along for the ride. It would add a bit of weight to your pack, but
probably not as much weight as an A.C. adapter would that would be capable
of operating over the wide range of power mains of the world.
Cheers,
Dave
