Does anyone own one of these?

A quick and dirty estimate to get amperage required is simply take charger wattage and divide by 10v instead of 12v. Using a lower number accounts for charger efficiency losses and a little extra wiggle room. If you do the full calculation for, say, a 350w charger: (350w/85%)/12v=34A. The quick and dirty method gives you 350w/10v=35A. Pretty darn close for estimation purposes.

On the house fire thing, that makes a difference. I personally would never simply twist and tape wires. Heck, I don't even like wire nuts (which are legal in elec boxes) because the wires are still exposed to air, oxidize which increases contact resistance. The only connection I like is soldering - when done right.

Thank you for another calc to add to my brain. I better save this page for future use in my decision. Your RCM name should Brian Calculator, with all of the calc pages you have supplied us with. Good info as usual Sir. I will continue my reseach for a PSU that fits my expected use. I may get a real nice on for the shop and later get a smaller one for travel.
