Date: Sun, 4 Apr 2004 19:13:44 -0500 In mid March, I posted an email below about using the 9V Radio Shack adapter with the Recorder V2. I actually needed to use it this weekend when my battery was about half dead, and 9V is too high in my opinion. It didn't kill it, but it did get really warm, and after the battery had been charged to 3/4 it gave off that characteristic smell that if I had not checked it, I might be replacing a voltage regulator shortly. Therefore I would use either the 6V Radio Shack adapter if you want to just buy one, or an 8V regulator with a diode. 6V will charge slower than the power adapter, but it's not worth smokin' the unit just to get it charged quickly. :) 9V is probably OK if it's charged, but I wouldn't take the chance now. (Sorry if you've bought one already; you have 30 days to exchange it.) Old email below: > So which car charger to use--and is the Radio Shack 9V too high; probably > not for battery charging. But when I wire this into my car, I will probably > use something like an LM7808, which is a small fixed-voltage 8V regulator. > 6V appears to be too low and anything much over the stock open circuit > voltage of 9.47 is probably too high. _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-04-05 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
