/ University Project - Portable Chargers
If any of you could find the time to complete the below survey, it would be greatly appreciated. Will only take like a minute of your time.

Done. Any ideas what you will use instead of solar? Seems like the only reliable portable energy available.
Define "available". Radioisotope thermoelectric generators have proven to be pretty portable and reliable ;-)
To the OP: I don't think your survey goes into enough detail. "How much are you willing to pay" depends very much on how much power the device will provide. £400 for 40 watts would be pretty good, £400 for 4 watts rather less so.
There are other things too, like the ability of the device to run unattended, and whether it requires hazardous materials in order to function, and whether it requires any maintenance during normal use, etc.
Technology wise, I am looking at body heat thermo generators, vibration utilisation, kinetic generation similar to that of self powered watches. Solar is plenty reliable, when we have some sun :P
nice (clicks on buy one now)... wait, what?... $200?
