Nope! no jug. The inverter on the specs is 1500 watt and to go to a larger inverter creates two problems. Firstly, the larger inverter will not fit in the space left in the battery box. No problem it can go in the so far unused space under the 2nd seat. Sure . . . if you want to pay over $1000 more to get the bigger inverter. Expensive cuppa - drat.
Today we found an even smaller jug - a Design Go Travel Kettle - at Ray's Outdoors. Not cheap at over $50 but only 650 watts. Not 2 standard cups either - holding only 400 ml - but packs up nicely and has auto cut-off. Boils 400 ml in about 5 mins.
