Re: Recharging digital camera batteries (AA grip)

I tried AA batteries in my grip once...once.

Well there are some good ideas.  I always carry 3 batteries, but one never knows just how fast one is going to go through them and when one is going to decide to up and quit.  Staying out for as much as a week needing 3 batteries per day would be tough. 

I don't know if the simple light weight 9 volt battery, the type that used to be used in radios before Ipods would work.  Light, may not last that long, but a 9 volt is a couple of bucks.  Best Buy had the batteries for about $40 bucks or so.  Yes I can get them cheaper, but I am not going to get them $2 cheap and if that $2 will charge a $40 buck battery all the better.

The back packs with the solar cells look interesting and could be a solution for a laptop battery, but its also a lot more than I wanted to spend at this point.  I bought two 4 gig CF flash cards at Costco last week for about 35 bucks.  Extra cards for me would make more sense than trying to deal with an image dump till I can get to power for the laptop.

I did see what looked like a grip for the body on KEH that took AA batteries.  The AA might solve the problem if a set of batteries would last as long as a battery pack.  Again that was also a couple of  hundred bucks, but I would at least get the verticle shutter release back.

I'm curious, what voltage batteries do they charge and how small do they fold?

Rolled plastic solar chargers have been used on boats now for about 10 years.  They're all over the web, just hunt them down.
