No you won’t. The generator runs on gas from the same tank that the engine uses, however, it stops sending fuel to the generator at about the same time the red light shows up on the dashboard telling you that you only have about 4 gallons of gas left.  That way, you can’t completely run out of gas for the engine when using the generator.

Here’s a good-to-know fact:

The traditional “noisy” generator used in the Travato from 2014 – 2021  (The QG2800) uses about 0.4 gallons/hour at half load and 0.5 at full.

The new “quiet” generator used in the Travato since 2021 ( The QG2800i)  uses:  No load — 0.14 Gal/h. Half load — 0.21 Gal/h. Full load — 0.46 Gal/h.

So, for example, if you run it for 8 hours overnight to have air conditioning while sleeping you would use about 4 gallons of gas.

NOTES:

For the Volta Pure 3 equipped Travato, the one hour manual or auto high idle cycle will also use approximately 1/2 gallon of gas per hour.
