Thinking of Buying an Elroq 55KW SE 50

I have a 1.0 litre Karoq at the moment and am thinking of buying a nearly new Elroq SE50. My annual mileage isn't that much (around 5,000 miles per year), mainly around town with the odd motorway journey of around 200 miles each way maybe once a year. The Elroq is a few months old with around 1,500 miles on the clock. My questions are:

Will I be OK with the 50SE given my low annual mileage or do I need a car with a bigger battery?

Not being a technical person, is it likely to be beyond me to use a public charger on my longer journeys? I don't have a mobile phone so will have to buy one.

Is there anything I need to look out for when I test drive the car next week? Thanks to all.
