Noco Genius G4 4 bank
Pros: Simple to use and light weight. Gives you a visual state of battery charge. So far has not damaged any of my PWC batteries internally.
Cons: Standard wires could be a little longer as to not have to use the included extensions.
Other Thoughts: Cost was a little more than a 4 Bank Battery Tender but I feel its additional features make up for it.
