This will depend on weather (like winter) and weight of the car. A friend of my had a full electric vehicle and had to go back to a gas car when we went on vacation, because the weight of his luggage in the car reduced 70 miles to around 25.
No idea what this means. What electric car has a range of 70 miles? Why would it change by over half due to adding weight that's tiny in comparison to the car itself? This does not pass the smell test.
Winter is more believable, cold weather does affect electric range and older EVs didn't have good (or any) thermal management on the battery. I would expect that a combination of fully loaded and cold weather to reduce range by 10-15% these days
He had to turn around and use another vehicle.
Without the luggage, range was normal in the same weather.
