My beloved digital SLR camera, a Nikon D3200, uses an EN-EL14 Li-ion battery that plugs into a MH-24 battery charger for charging. Both the charger and the battery came with the camera and the charger has a standard 3 pin UK plug configuration for plugging directly into a UK socket. The rated output of the battery charger is 8.4V DC at 0.9 amps whereas the battery has a rated capacity of 7.4V at 1030 mAh. The battery pack is the sole supply of power for the camera ie there's no option to use conventional alkaline batteries of any sort.
I'll shortly need to take the camera on a canal narrowboat that does not have an inverter fitted so there will be no 240v AC supply to charge the battery. The only electricity onboard is a 12V DC supply supplied by the onboard batteries.
Can anyone suggest how I can charge the battery overnight? Are there any mini inverters available that would do the job given the relatively little current demand of the battery? It would obviously have to have a standard socket on the device so I can plug the charger in. I don't really want to consider buying another camera to take with me.
Thanks Chris. It's good advice. My only concern is how long the charge would remain in the batteries concerned. I need to be on the narrowboat for 21 days. Do you think that the batteries will remain charged for that sort of period if I charged them at home prior to the trip?
12v to mains inverters are readily available. I have 2 of them; one plugs directly into a 12v socket and has a mains 3-pin socket at the other end, the other, rather older, is a box with a wire leading to a 12v plug. I use then for exactly the reason you want one.This one is on Amazon:
