I recently bought an external battery for my N9 which charges either using the solar panel or through a usb charger.

It then has a USB port which can be used to connect it to various devices to charge them.

The problem is, EVERY flipping device works apart from my stupid N9.

This is irritating, I constantly get the "Insufficient power to charge device"

This would be fine if it just happened on the external battery, but I also get this message on my PC AND my Laptop!

The N9 also detects the USB lead as a computer constantly asking what mode I want it in

"Mass Storage/Sync and Connect/SDK"

Its not being connected to a PC just a battery so why is it asking me for a mode? It also seems to be charging for the first few seconds then when I select a mode of just select nothing it gives me the Insufficient power message.

Im running out of things to try
