Also, would love to see a USB charger cable for the 770, I have a battery pack I built with a USB plug, it looks like I am going to have to build or get the parts. So far I think I have found USB to the old style nokia power plug and the CA-44 adaptor should plug into that. But if they are not exactly like the pictures and the description on Amazon, I will have to break out the side-cutters, tape and the meter and do some cut/splicing
