The 5 trolleys we have here are all fitted with the Mascot 300W sine wave inverters Robert mentioned for two years now. We limit the equipment the number of items on the output to typically run at around half load with typical current from the 12V supply being 8 to 15 Amps (the norm usually being towards the bottom end of these figures) depending on devices running and their internal battery status.
This inverter is fitted with a 40 Amp internal fuse, therefore the cable fitted to the input is rated accordingly.
