I find myself faced with having a lot of things to charge on the boat. There is stuff plugged in everywhere. I'd be interested in the solutions others have.
My own context: I have shore power in a slip most of the time, a generator, and a large battery bank and inverter. I try to unplug chargers when I'm not using them since the wall wart draws current even when it isn't plugged into its appliance.
Icom h/h VHF, 120V charger
Std Hor h/h VHF, 120V and 12V chargers
cell phone, 120V and USB chargers
iPod, 120V, 12V, and USB chargers
laptop, 120V and 12V chargers (can charge USB devices)
backup h/h spotlight, 120V and 12V chargers
backup SSB receiver, 120V charger (not used much and can use AA batteries)
electric toothbrush, 120V charger (lasts several weeks on a charge)
The VHF radios last 20 - 30 hours of receive with minimal transmission; I have a fixed VHF w/ a cockpit mic so they are mostly used from the dinghy.
The cell phone lasts a day or two per charge.
The iPod lasts almost a week even when used many hours a day.
The laptop gets used a lot - even under sail. I generally have it in a dock running directly off 12V so the battery stays charged.
Even if I don't use it the spotlight needs to be charged once a week or so; any significant use and it needs to be charged for many hours - 10 or so.
I have some ideas and I've been overthinking this in my own style for some time. I'm looking for a simple and elegant charging set up and regime. Opinions welcomed with open arms. I'll post what I decide to do when I am done.
