Re: Any ideas of a good 12V Power Outlet to connect my GPS?
Hey guys, a good general rule of thumb for anything that charges via a USB standard (so pretty much every phone and GPS unit) is to assume a maximum draw of 11 Watts from the unit, plus whatever inefficiencies are inherent to your charging adapter. So maybe 15 Watts with a safety margin or around 1.25 amps on the 12V leg per device.
