Nothing for an hour or less if you are going to use a "real" battery (2600mAh). I just received one of these:

but I am returning it. The charger itself is a little bulky, and the AC adapter is a brick. Instead I am going with one of these: http://www.all-battery.com/ProductIm...arger/6280.jpg
(cheapest battery+charger price is the "all-battery" store on eBay-- has the charger + 16 AA 2600mAh cells for about $45 shipped.

Though, I am thinking of the sub-C battery pack route (a couple of these 4.8v 5000mAh packs- http://www.batteryspace.com/index.as...ROD&ProdID=201) and a quicker charger (http://www.batteryspace.com/index.as...OD&ProdID=3005). The charger looks relatively light but the batteries are heavy (25oz for the 2 packs, in total), though they will hold tons of juice (though less, in total than all 16 of the AAs combined). Recharge time would be 2.5 hours per pack. However, total price jumps from $45 shipped for the AA set-up to $90 shipped for this setup. The 5 hour total recharge time is not worth it to me, and there is a 9oz weight penalty (at least) with the sub-C route.
Going the sub-C route would mean using lithiums for the camera, which isn't the end of the world (or bringing a small 2 cell MiMH charger).

In any case, a truly "quick" charger needs to push some amps, and the travel-friendly 120 gram power adapter that comes with the lower charge rate "quick" chargers is not going to cut it. I think you only get to pick 2 of these 3: low weight, high capacity, quick recharge
