Can I charge Sony EX1/EX3 style batteries (BP-U60 or similar) using 12V car power?
A. All our chargers for BP-U60 batteries require 18V-20V DC power. Normally it is supplied by the 19V AC adapter that comes with a charger. For the 12V DC power source to be used (car power) we suggest ordering a voltage adapter PST-ED1075-19 2.1mm plug (for TC400-EX/40EX) or PST-DC2171 2.1mm plug (for TC200-EX) from http://powerstream.com when ordering our battery charger. This DC adapter would be used instead of the AC adapter when you need to charge the batteries in the car.
