This is a well made, well designed two-battery charger for Sony L series
batteries which gives feedback on charging status of batteries via an LCD
screen. It has adaptors for charging batteries via mains power (110-240 V
AC), a 12 V vehicle adaptor and can be connected directly to a compatible
Sony camcorder. My only criticisms are that it is expensive, quite large
and fairly heavy (>300 grams), and according to the user instructions,
should not be subjected to vibration while in use. If this is a real
problem, I'm not sure how useful the car charger will be...
