Guys, if you need to drag around a generator trailer, you may as well just get a hybrid car and just run it on battery, because a hybrid already has a gasoline engine built in, that is essentially your "generator trailer".
The whole point of getting an EV is to be as gasoline free as possible. Again, if you ONLY compare the possibilities of extending the range, it boils down to the following:
- Adding more battery
- Adding a electric generator
- Adding a generator trailer
We've already ruled out that adding more battery is not beneficial due to its weight and it will be expensive, not to mention the usage is one charge only, if you depleted the battery, you will have to stop and recharge. So adding battery to increase the range is a no-no.
Now if you look at the next 2 possibilities, they are basically doing the same thing. They both takes gasoline and convert into electricity. Comparing them side by side, you can see the clear winner is the portable electric generator...
Weight (lighter): portable generator win
Size (smaller): portable generator win
Re-usability (backup power): portable generator win
Cost: MAYBE generator trailer if you build the whole thing yourself, otherwise for non-DIYer, there is no such thing as generator trailer that is ready for you to haul around. So portable generator win...
Availability (where to buy): portable generator win
Capacity (re-fueling): Technically, generator trailer have a bigger capacity, but that's also because the engine burns hellalot more gasoline than portable generator.
Efficiency (way greener): portable generator win
