The charging light goes from the bolt to nothing again after a few seconds once plugged in to the solar/battery charger... As far as i know there are not ant "charge converts" made for the Storm nor could i find one for just the usb... How do i go about jumping the data pins to give constant charge to the Storm... ?? A DIY web site stating the procedure would be great as i have yet to find one myself... =] Thanks... =] I am having a similar problem with my Blackberry Storm… The charging light goes from the bolt to nothing again after a few seconds once plugged in to the solar/battery charger… As far as i know there are not ant “charge converts” made for the Storm nor could i find one for just the usb…

How do i go about jumping the data pins to give constant charge to the Storm… ??

The iPhone is perfectly capable of charging from the 500mA that a standard USB port puts out. The problem is the phone - the 3G and 3GS are designed so that they will not accept a charge unless they detect an appropriate voltage on the USB data pins - which most USB-based charging devices (like the Freeloader) don't use. It's certainly possible to get around this - several people have used resistors tapping off the 5V USB power line to provide 2.5V to both the data pins - but it's fiddly and not particularly neat. There are a couple of "charge converters" knocking around, made by Ridax and Griffin respectively, which supposedly solve this problem. It’s not the amperage.

The freeloader is incapable of delivering the required current for more than a couple of seconds to charge an iPhone. A freeloader could in theory charge individual batteries which could then be used to charge an iPhone but waste your time. A solar charger to do the job needs to be capable of outputting 5V at 1AH so needs an internal battery rated of at least 5.5V at 2.5AH to be suitable.
