Code:
[root@kindle root]# gasgauge-info -l
-23 mA
This is what I get when wireless is on and my kindle is in partly cloudy sunlight (well, Munich ;-), so it still charges with 23 mA with some load present.
The maximum I could get so far were 40 mA (Wireless on). But I also have to say that the battery is 90% full now, so maybe the charge controller already starts limiting the current.
