Which one is right for you?

For permanent van life use, the best efficiency and durability (where every watt-hour from the leisure battery counts) → Dometic CFX3 35 (0.47 kWh/day, premium build quality). For occasional camping on a tight budget and more volume → Alpicool CX40 (40 L, from €170, almost a quarter of the price). If you are out and about a lot and off-grid, the efficiency pays back; for occasional use the Alpicool is easily enough.
