I doubt it would do any harm, so long as the volts and amps delivered are similar yo the power unit supplied by Archos. I will say that 2-2.5 hours sounds very poor performance however. I certainly get a lot longer out of mine. How do you charge the unit? Do you remove the power as soon as the charge shows 100% in Rockbox? If so, leave it overnight, as Rockbox currently shows 100% long before the charger stops charging because the battery is full. -- Mike Holden Rockbox page: http://www.mikeholden.org/~rockboxReceived on 2003-08-12 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
