In theory you can use the higher current rated supply with no issue, assuming that you've got a purely resistive load, thus drawing only 1.8 Amps even though the supply you're feeding it with could supply up to 2.1 Amps. [This is simple Ohm's Law.] So using the other supply will most likely work. -- Chris Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Oct 6 - Creating Browser Extensions for Firefox and Chrome Nov 3 - Open Source Hardware: Bugs, Beagles and Beyond Dec 1 - IBM's Open Client Deployment
