I just got my powermonkey explorer so I could power/charge my zaurus c1000 + c860,

I was wondering if anybody has any input regarding this device and how one can maximize it's use happy.gif ? As I stand, I hope to also charge my psp, zune, and misc. items. Does anyone know if I can charge the powermonkey via included solar charger while powering a unit??? (charge while discharging)

Also, what can I use my solar charger for (other than charging the powermonkey)?

thank you
