How about this:

It is about $7 and is already waterproof.

I will keep your amazone link in mind, I have recieved the one I orderd and it works only I am not sure it is waterproof allready. Was able to charge my mobile for the lipo with it.
Planning on doing some testing about the amount of current that is running through it when working under different loads. Only did not find time for it so far

I can now testify that it is not guarded against reversing the + and -, it gave a nice small explosion when I made this small mistake. So I am going to order two new ones. One to power my Arduino one to power my webcam.
