Try an external Solar power device with integral Lithium polymer battery... something like a PowerBee... charges from the sun (slowly) but can also be directly charged with PSU and can then charge Sony eReader for two and a half full charges and it's only a bit larger than a larger smartphone...

Not an improvement for many but I am often away from a power source and get panicky when my battery goes down to the last 1/4 mark.
