I´m leaving tomorrow afternoon for a week trip to the south of Chile, probably with outstanding scenery for photography and just realized my charger (and probably my second battery) are stored in an unknown box in a mess I have as I left my apartment and All my stuff is sitting on my Mom´s patio

Just been looking around but there is very little chance I will have the time to find them so I would like to know any ideas on how to charge it without it, thought of USB but google says it can´t be done, Nikon here does not have a battery or charger on stock so I´m running out of time...ideas or whatever as jokes to cheer me up will be welcomed

pd: just emailed a friend that has a D90 but think he is out of town, will check tomorrow morning, going to sleep now.

thanks!
