And, of course, they all have different batteries. All different shapes, sizes, colours, and voltages...
So, when we travel I usually end up having to carry a whole passle of power supplies and chargers. It's got to the point that I have a small case where I can pack all the electronic widgetry.
I was rather pleased to track down a rather useful gadget from the folks at Hama. It's a "Li-Ion Photocharger Combi", which is basically a battery chargers with interchangeable faceplates that allow it to charge pretty much every camera battery on the market. Plug-in the appropriate faceplate, decipher the slightly confusing instructions as to just how to slot in the battery, connect it all up and watch the little green light flash. It's also a lot smaller than I thought it would be.
It's working for my Canon, Casio, Ricoh and Nikon batteries. There's a fairly long list of supported types, so I think I'm covered for the moment.
Only one device for the suitcase next trip. It's even got a car charger. I'll just have to find an appropriate 12-volt AC adapter for it in the US...
Not bad for £18 or so...
