Default Ship to shore or battery charger??

Who has ship to shore power on there boat and who has a battery charger installed? I want somthing for during the season, I remove the batteries for the winter. I trailer my boat for now, and I keep it at my home. There is a designated spot next to the garage for the boat. Should I install a ship to shore charging system or just install a battery charger. I have used a small portable battery charger with a extension cord up till now. I would like somthing of better quality, and maybe install an outlet on the boat side of the garage.

It depends on what you want to spend. Obviously a marine grade smart charger, with a 110V AC breaker panel and a regular shore power cord is "best", but I've had good luck with simple trickle chargers. If you have a 12V cigarette lighter you can turn on all the batteries and charge them through that.

NEVER use a portable charger connected to dock power with the boat and motor both touching salt water, however. You would not believe how many people try to save a buck on an improperly installed charger and then blame the marina for having bad power when their outdrives dissolve in a couple of weeks.

I've never installed one, but the chain stores sell simple little Guest chargers that you can hard wire to the battery and then install a Marinco 150BBI or equivalent in the hull of your boat. When you plug into shore power you will light up the charger, and just unplug to shut it off. It takes a standard extension cord

Cheap portable chargers drink electrolyte. You either get away cheap on buying the charger AND pay for new batteries every year or buy a decent charger AND pay for new batteries every 3-5 years. Your choice.

Get a good quality marine grade charger even if you simply plug it into your garage extension cord and clip the output to your batteries between trips. Even then, I put a timer on the AC and only turn it on about an hour a day.
