Has anyone tried one of these ? http://www.roadking.co.uk/24v-inverters/150w-can-inverter-24v.html
I need something reasonably cheap to run my laptop on occasional nights out (15V 6A). Also got a USB connection for charging the phone. I mostly use a Merc Atego. Pretty sure the lighter socket is 24V, but can’t find any information on the load capability.
