I want to plug in a 300 watt inverter into the vans Hab system. If I then use it to charge a MacbookPro laptop which uses a 60 watt charger plug. Allowing for losses, what am loading the system with ?? The socket runs from a 10 amp fused circuit.. I will be most grateful if one of you techno electrical wizards could help ....PS. I think the laptop charger works at between 18 and 20 volts.

If you are charging something that requires 60 Watts, then you will be drawing 5 Amps plus a little bit for the invertor loss

Thanks CJB.. I got tangled up with the 20 volt draw at 60 watts and came up with 3 amps "plus a bit" for losses.
This getting old lark has dulled my brain.. PS.. Where did the "Thanks" box go ??
