Here's another contender for a Made By Students category, maybe?...Portability is not always everything. Check out, for example, this alternative way of charging your phone. Needs must, and the necessity is the mother of invention, etc, but don't try this at home unless you know what your are doing.
What could possibly go wrong?

And it is, writes the website, a step above the best-selling first model (!)

Wow, no kidding I did exactly the same thing some months ago using the same TTI PSU! Certainly works, and a lifesaver when you've forgotten the standard USB lead :D

And what's wrong with this? I use a similar arrangement all the time for my wife's Sony Ericson phone, whose mains charger died a while ago but we still have a car charger! Where would I be without my Thandar bench PSU?

It looks like a standard car charging lead, connected to a bench power supply (set to approx. 12V) rather than plugged into a car's cigar lighter socket.
No, I wouldn't try this at home, not having such a power supply there - but I've done it at work several times!

Nowt's wrong with this Paul, as long as you know what you are doing! :-)

"What can go wrong?"
Almost nothing. Using a car charger in a car is much more dangerous, since if there is a bad connection somewhere the lighter socket can give transients of up to 300 volts, and the normal running voltage, as any CB'er knows, is 13.8 volts. Certainly you could probably burn the charger by whacking the voltage up, but my guess would be that you would have to make it very high for a significant time and the phone would probably survive.
