I have the PL6 and absolutely love it. Started to get the PL8 but decided to save some money and am glad I did. I have never even got close to maxing this thing out. This should be the last charger I ever need (famous last words)
Here are specs for a PL6 straight off Revolectrix site:

Size: 5.70" x 5.57" x 3.40"
I have not used an iCharger so I have no input on them, but several at my field are using them and really like them. Like has been mentioned above the PL's are more expensive than the iChargers, However when I bought mine there was only $30 difference between the PL6 and the equivelant iCharger.
I say if its down to these two and money isn't the deciding factor, pick the one you like the best they are both great units.
