Re: iPad - the charging conundrum
Yes, but I'm tackling one issue at a time.
It doesn't make a whole lot of sense to tackle one thing at a time when they are interrelated. If you need lights then you need a basic electrical system, which can be extended to cover the iPad problem and bilge pump problems.
By the way, have a small solar charger on my 12' dingy which I use to get to my moored boat. It keeps the battery charged very well and has no controller. I don't run the outboard enough in the short hop to the big boat to charge the battery but the solar keeps the starter and the bilge pump for the open dingy and the running lights operating well for the whole summer.
