Portable cooling seems perfect for camping, but energy draw is always a concern. Many 12V models claim low consumption, yet real-life results vary. How long can they actually run without draining batteries?

That really depends on your setup, but a 12V fridge can easily run 24–48 hours on a mid-sized battery if you manage it right. Pre-cool the fridge before disconnecting from shore power, keep it full, and avoid opening it often every minute open drains more energy than people think. I use a small solar panel during the day to top up. Insulation also matters; covering it lightly at night helps keep the cold longer. With planning, it’s perfectly reliable off-grid.
