was browsing other Treo sites and came across this item at www.treo-gear.com

oh darn the link doesn't work. It is described as an external battery for the Treo 600 and is listed in their clearance dept.

it is designed for the Treo 600. But I was wondering if it would work for the 680? Anyone out there that has had a 600 and now has a 680? is there a lot of difference in the case? do they even use the same kind of power adapters?

I got a "power sled" for my T3 which has come in handy on long trips. This looks like the same concept.

Wondering
