My web page has my method of using solar power with a battery and car adapter, However, I found that a 12 volt pack of NiML batteries will jump start the Libretto without a car adapter, when full I found that with a three way plug, I could use the 12 volt battery to a lower voltage. Solar alone would let the Libretto see no input voltage when the solar output goes below about 9 volts and will not show input until the solar input goes above 14 volts. http://www.billcotton.com/bicycle_electric.htm I almost lost track of all of the changes that I have made since 1999 when I bicycle from Philadelphia PA to Wesley MA using my Libretto as moving map with a gps than didn't have built-in maps. On this trip, I recharged the external and internal battery from the Libretto wall unit, each night. http://www.billcotton.com/bike.htm This was with a 7 amp hour external battery. www.billcotton.com N40° 3.744' W75° 6.180' ----- Original Message ----- From: "Gerhard Kapusta" <[EMAIL PROTECTED]> To: "Libretto" <[email protected]> Sent: Wednesday, August 09, 2006 1:52 AM Subject: [LIB] Libretto solar powered?

I've planned a journey to an area without electricity, where I would like to use my Libretto for storing digital pictures and for diary. Does anybody of the listfolk have experience how to operate a Libretto with solar power? I've already found rollable and foldable panels on the market, but the main questions are: - Nominal input for the Lib is 15V, which fits to the output voltage of standard panels (under good light conditions). But what happens if the panel voltage is reduced because of clouds etc? Does charging continue with lower current? Or does charging stop? - 2nd importent question is the right size of the panel. The standard power adaptor is designed for 30W/2A which is quite huge for a panel which should fit into a backpack... - A smaller problem is to find a source for a power plug - maybe somebody has a damaged power adaptor to sell, where I could cut off the cable with the plug! Are there any hints avilable? regards Gerhard _________________________________________ Gerhard Kapusta Email home: [EMAIL PROTECTED] Fax&Voicebox: +4912120-201115
