A 5V 500mA supply means 250mA max. after conversion to 9V with a 90% efficiency voltage doubler. Charging 1200mA batteries at 250mA would take around 5 hours. Would that be OK? What is the Archos operating current consumption? Is it below 250mA? Received on 2003-01-08 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
