Daily use of Neo1973

I have a Motorola A780 mobile, and the charger that comes with it has a 
mini-USB connector, and it charges the Neo1973 very good for me. It also 
handles a 500mA load.

As far as I know, Motorola has a number of mobiles that uses a mini-USB 
connector, so I guess it should be possible to get such a charger 
without too much trouble.

I don't know about a car charger (I have dis-selected having a car :-) 
so I can't advice you about that.
