Wanted to add, as much as I like the fuel rod, for those thinking about buying one, check the map where the kiosks are.
I don't understand why every resort doesn't have a kiosk or why AK only has one kiosk but MK has 5. If someone stays at a resort without a kiosk and goes to AK a lot, one may think the offer to be awful. And even though you can charge the fuel rod yourself at night, the value of it is you shouldn't HAVE to do that.
