Yeah, I was aware of the charging issue, but the “cold boot” issue seems like it could be a tad annoying. Maybe the warning voltage warning for being on adapter could be modified below that “cold boot” voltage level….
On the one-slot AC/charger, my thoughts were: I’m usually on sticks, so keep the battery mounted (but’s cam’s on AC), it’s ready for the handhelds, turn cam off during breaks & lunch, so it’s charging. For longer no-AC days I’ve already got some old (recelled) ProPacs and an older charger. When not shooting I use the camera as a “feeder” to my NLE, so it can sit battery mounted, AC in, mostly in a charge-state.
Mostly I just loved the idea of a cam-mounted AC adapter. HOWEVER, I think if I want more LiON batteries (aka Dionic), I’ll buy one from a non-AB vendor for about 30% less (with it’s own charger in that price).
