Just wondering if anyone has considered or is using for a 12 volt DC power source, one of the many "jump start" type of battery, jumper cable, and lighter plug kits that are available. West Marine has one listed for marine use, Prestone has one available, Road Pro, Sears and there are probably many more. It's a 12 VDC power pack with jumper cables, a lighter plug, and some have a built in light, available power gauge, air compressor or some other accessories that is rechargeable from 110 AC house current, or maybe 12 VDC from your vehicle cigarette lighter plug while you are driving to the launch site. They are a sealed (not gel ) type, and are rated in the neighborhood of 12 - 17 amp hours, depending on the specific company. They are to be used generally in an upright position, however they are capable of withstanding non-upright orientation for short periods. I'm wondering if this might be a viable source for power for GPS, Fishfinder, Spotlight, and running/anchor lights, or the electric hair dryer for my admirable. Any thoughts? Thanks for the ideas, expertise, and input ;-) in advance. Harvey & Deena H M-15 #348 Pelican Walla Walla, WA Just seemed to me that this might be a good power source for serving a multipurpose use.
