We use a laptop for a Telzon UPC reader for inventory. It's a Mobile unit and has a car battery, dumping into an inverter to power up the laptop battery. It'll run about 2 to 3 hours before having to be plugged into the wall to recharge the deep cycle car battery. Kind of a pain but can't pull the rig around with an extension cord.

I suspect that boaters using inverters would have a very short battery life.

hi skip, if all you are using inverter, is for laptop , get a adapter charger 12v to laptop...sometimes called airline adapter around $50 bucks or so, belkin maybe, alot of ones out there...no need for inverter battery adapter laptop...less draw on battery.... be sure to get correct plug to fit laptop.....if more ?????????? call me 509-486-4508 mikkel thesolarshop 12-5 m-t-w pst peace
a x v=w...........laptop 60 w 75a battery x 12v=900w for longevity of battery only discharge 50% 12.1 v read when no load or charging =450w / 60w =7.5 hrs from battery plus battery in laptop
solar panel maybe 6watt not very big............. might go bigger
Skip,
I have had a 600W inverter for the better part of the 10 years I've owned my CP23. No problem since I replaced the original too small type 27 wet cell with a 8D (255AH) AGM. The first battery going had nothing to do with the inverter and everything to do with using the nav lights and anchor light and depth and VHF for days at a time and running the battery down, plus letting it discharge over the winter, plus having it over charge in summer before I got a charge controller on my solar panel.
Battery life is greatly extended if you don't actually ever use the inverter. If I really need to use a (small) power tool on the water, its there. If not, I don't use it.
