Any ideas of a good 12V Power Outlet to connect my GPS?

[hacc81]

Hello all, I just joined a couple of days ago...
A week ago I bought my first bike, a 2008 Suzuki Marauder 250 (Canada model)... So far, a great choice for me!!
I'm back to school and I have to commute everyday (about 60 kms/day) so mainly I'll try to use it as much as I can.

Anyway, I have a big screen GPS (Garmin 1490T) and I bought a RAM Mount for it that works perfectly!!
But last weekend my wife and I went to Vancouver and the GPS run out of battery fairly quick.
So I'd like to know if any of you have installed a 12V Power Outlet on your GZ250? If so, where do you got it from? So far, I've only found these options:

And honestly, both look kind of cheap (sorry to the guys of cycleblind.com)

So, if anyone can tell me if these options are any good? or if you know of some better option, please let me know...
Also, if anyone know an easy way to install it, it'll be welcome too...
